Geochemistry and Ore Bodies: Why Six Metals Trade as One Basket
Platinum, palladium, rhodium, ruthenium, iridium, and osmium (PGMs) are grouped commercially
because they share a geochemical fingerprint, not because they are chemically identical.
All six are siderophile/chalcophile elements that concentrate in mafic-ultramafic magmas and typically
occur together in the same ore — a single tonne of Bushveld reef ore might yield 2–10 g/t of
combined PGM content, but almost never yields only one of the six metals
(
British Geological Survey, Platinum Mineral Profile).
1. Siderophile behaviour and crustal scarcity
The platinum-group elements are classified geochemically as siderophile (iron-loving) and chalcophile
(sulphur-loving), meaning they partition preferentially into metallic and sulphide phases rather than
into silicate melts during planetary differentiation. This is why PGMs are extraordinarily scarce in
the Earth's crust — most of the planet's PGM inventory sank into the core during early
differentiation — with average crustal abundances in the low parts-per-billion range. Relative to
other rock types, PGEs are enriched in ultramafic lithologies such as peridotite, where platinum and
palladium concentrations are commonly 10–20 parts per billion, still requiring massive tonnages of
rock to be processed for each ounce of metal recovered
(British Geological Survey, Platinum Mineral Profile).
This scarcity, not any single supply disruption, is the structural reason PGM ore grades are measured in
grams per tonne rather than percent.
2. Typical ore grades: 2–10 g/t on a 4E or 6E basis
Economic PGM ore grades vary by deposit type and mining method but cluster in a narrow band. Underground
narrow-reef mining of the UG2 chromitite typically requires a minimum cut-off around 2–2.5 g/t 4E
(platinum+palladium+rhodium+gold), while open-pit disseminated deposits such as Platreef can be mined
economically down to roughly 1–1.5 g/t 4E because of lower operating costs per tonne
(industry mining-engineering rule-of-thumb summary, 2026).
Reserve-grade assays published by South African and Zimbabwean producers show Merensky Reef grading
around 2.3–4.1 g/t 4E, UG2 grading 3.3–3.5 g/t 6E, and Great Dyke reserves in the
3.3–4.2 g/t 4E/6E range
(PorterGeo, Great Dyke ore deposit description;
NS Energy, Mimosa Platinum Mine).
Norilsk-Talnakh sulphide ore in Russia runs to a notably higher combined PGM content of roughly 8.6 g/t
alongside substantial nickel and copper credits, reflecting its magmatic sulphide (rather than
stratiform reef) genesis
(Nornickel, 2019 Annual Report, Business Overview).
3. Mineralogy: sulphides, tellurides, arsenides, and alloys
The six PGMs do not occur as native metal nuggets but as discrete micron-scale mineral grains —
sperrylite (PtAs2), cooperite (Pt,Pd,Ni)S, laurite (Ru,Os)S2, and various Pd-Pt tellurides and
bismuthides — typically 20–60 microns in size, hosted within or adjacent to base-metal
sulphides (pentlandite, chalcopyrite, pyrrhotite) and chromite grains
(Journal of Petrology, Merensky Reef PGM mineral associations).
This mineralogical intimacy with base-metal sulphides is precisely why PGM mining is inseparable from
nickel-copper mining at Norilsk-Talnakh and Sudbury, and from chromite mining at UG2 — the PGM
grains report to the same flotation concentrate as the base metal or chromite value, and PGM recovery
depends on capturing that concentrate stream intact.
4. Ore body classification across the major provinces
| Ore body / province | Country | Genetic type | Key operators |
|---|
| Merensky Reef, UG2, Platreef (Bushveld Complex) | South Africa | Stratiform PGM reef in a layered mafic intrusion | Amplats, Implats, Sibanye-Stillwater, Northam, Royal Bafokeng |
| Great Dyke | Zimbabwe | Stratiform PGM reef in a layered ultramafic intrusion | Zimplats, Implats (Mimosa, Unki) |
| Norilsk-Talnakh | Russia | Magmatic Cu-Ni sulphide with PGM as by-product credit | Nornickel |
| Stillwater Complex | United States (Montana) | Stratiform PGM reef (J-M Reef) in a layered intrusion | Sibanye-Stillwater |
| Lac des Iles | Canada (Ontario) | Disseminated PGM in a layered intrusive complex, palladium-dominant | Impala Canada (Implats) |
| Sudbury Basin | Canada (Ontario) | Magmatic Ni-Cu sulphide with PGM as by-product credit | Vale, Glencore (Sudbury INO) |
Why it matters: the stratiform-reef provinces (Bushveld, Great Dyke, Stillwater) mine
PGMs as the primary value driver, while the magmatic sulphide provinces (Norilsk-Talnakh, Sudbury) mine
PGMs largely as a by-product credit on top of nickel and copper. This distinction explains why Russian
and Canadian PGM supply responds to nickel-price and nickel-demand cycles as much as to PGM prices
themselves, whereas South African and Zimbabwean supply responds directly to the PGM basket price.
Current status (July 2026): The Bushveld Complex remains the anchor of global PGM
reserves, hosting the large majority of identified world PGM reserves according to USGS
(
USGS MCS 2026, platinum-group metals chapter).

4E, 6E, and Pt-Equivalent: Why PGM Disclosure Is Not Standardized
There is no single global PGM reporting standard. South African and Zimbabwean
producers commonly report 4E (Pt+Pd+Rh+Au) or 6E (Pt+Pd+Rh+Ru+Ir+Au), Russian and North American
producers commonly report 2E (Pt+Pd) or 3E, and Johnson Matthey's market-balance reports treat platinum,
palladium, rhodium, ruthenium, and iridium as five separate, individually balanced markets rather than
one basket.
1. The 4E and 6E conventions explained
Implats' published glossary defines 4E as "the sum of platinum, palladium, rhodium and
gold content as determined by a nickel sulphide collection fire assay procedure," and 6E
as "the sum of platinum, palladium, rhodium, ruthenium, iridium and gold content" by the same assay
method
(Implats, Minerals Report glossary).
Sibanye-Stillwater's reserve disclosures confirm the same convention for its South African operations,
explicitly noting that "4E" covers platinum, palladium, rhodium and gold while "6E" adds ruthenium and
iridium, with base metals (copper, nickel, cobalt, chromium) valued separately in the basket-price
economic model
(Sibanye-Stillwater, Mineral Resources and Reserves report).
2. Regional divergence: why US operations report differently
Sibanye-Stillwater's own disclosure highlights the contrast directly: its US Montana PGM
operations report only 2E (palladium and platinum), because "other associated precious metals,
such as rhodium, iridium, ruthenium, osmium, as well as gold and silver occur in low concentrations and
… are generally not material to the estimation or calculations" at Stillwater's J-M Reef, in
contrast to the 4E/6E basket used for its Bushveld operations
(Sibanye-Stillwater, Mineral Resources and Reserves report).
This means a "PGM production" figure from Montana is not directly comparable to a "PGM production"
figure from Rustenburg without adjusting for the metal basis — a frequent source of confusion when
comparing company disclosures across jurisdictions.
3. Grade variance by ore body under the same convention
Even within the 4E convention, the metal split differs sharply by ore body: published assays show
Merensky Reef running roughly 63.5% platinum / 28.1% palladium / 4.4% rhodium / 4.0% gold of its 4E
content, UG2 running roughly 56.7% platinum / 29.4% palladium / 13.0% rhodium (a much richer rhodium
credit), and Platreef running a near 1:1 platinum-to-palladium ratio at roughly 45% each with a higher
6.0% gold credit
(IntechOpen, Extraction of Platinum Group Metals).
UG2's disproportionately high rhodium content is one reason South African supply dominates the global
rhodium market even though rhodium is a minor share of overall basket tonnage.
4. Johnson Matthey's five-metal disaggregated balance approach
Johnson Matthey's semi-annual PGM Market Report
deliberately avoids a single combined "PGM basket" balance, instead publishing separate supply-demand
balances for platinum, palladium, rhodium, ruthenium, and iridium (osmium is excluded as commercially
immaterial). Its May 2026 report notes that "the five platinum group metals… are often discussed
as a group, but their outlook for 2026 is anything but uniform," with platinum set for a fourth
consecutive deficit while palladium and rhodium are forecast to move into small surpluses
(Johnson Matthey, LinkedIn PGM Market Report summary, 14 May 2026).
This disaggregated treatment is the industry-standard analytical approach precisely because 4E/6E basket
reporting, useful for mine economics, obscures the highly metal-specific supply-demand dynamics that
drive each PGM's price independently.
Current status (July 2026): No convergence toward a single global PGM reporting
standard is underway; 4E/6E remains the South African/Zimbabwean norm, 2E/3E remains the North
American norm, and market reports from Johnson Matthey, WPIC, and Heraeus treat the five commercially
significant PGMs (Pt, Pd, Rh, Ru, Ir) as individually balanced markets. Watch: any
future harmonization push from SAMREC/CRIRSCO reporting-code reviews.

Geographic Concentration: The Defining PGM Supply Risk
South Africa and Russia together account for roughly 85%+ of global PGM mine supply
— a concentration level higher than almost any other industrial metal complex. USGS reserve data
show South Africa holding
63,000,000 kg of PGM reserves against a world total of more
than
76,000,000 kg, i.e. roughly 83% of identified world reserves
(
USGS MCS 2026, platinum-group metals chapter).
1. Reserves: South Africa's near-monopoly
USGS's 2026 reserve table lists South Africa at 63,000,000 kg of PGM reserves, Russia at roughly
1,011,000,000 — recorded in the source data on a different combined basis reflecting Russia's
Norilsk-Talnakh sulphide system — Zimbabwe at 1,300,000 kg, Canada at 310,000 kg, and the United
States at 590,000 kg, against a world total exceeding 76,000,000 kg
(USGS MCS 2026, platinum-group metals chapter).
Natural Resources Canada's tabulation of the prior year's data similarly shows South Africa at 63,000
tonnes (77.5% of the 81,330-tonne world total), Russia at 16,000 tonnes (19.7%), Zimbabwe at 1,200
tonnes (1.5%), the United States at 820 tonnes (1.0%), and Canada at 310 tonnes (0.4%)
(Natural Resources Canada, Platinum facts).
The Bushveld Complex alone represents about 75% of the world's platinum resources and about 50% of
world palladium resources, with the Merensky and UG2 reefs together containing approximately 90% of the
world's known PGM reserves
(Bushveld Igneous Complex, geological reference summary).
2. Mine production: 2024–2025 country breakdown
| Country | Palladium 2024 (kg) | Palladium 2025e (kg) | Platinum 2024 (kg) | Platinum 2025e (kg) |
|---|
| South Africa | 82,600 | 70,000 | 126,000 | 120,000 |
| Russia | 89,000 | 84,000 | 22,000 | 20,000 |
| Canada | 17,000 | 16,000 | 5,700 | 5,000 |
| Zimbabwe | 15,200 | 15,000 | 18,400 | 18,000 |
| United States | 10,200 | 6,200 | 3,010 | 1,800 |
| Other countries | 2,870 | 2,900 | 3,860 | 3,900 |
| World total (rounded) | 217,000 | 190,000 | 179,000 | 170,000 |
Source: USGS MCS 2026, platinum-group metals chapter.
On these figures South Africa alone supplies roughly 63% of world platinum and 37% of world palladium
mine production, while Russia supplies roughly 12% of platinum and 44% of palladium — confirming
that South Africa dominates the platinum side of the basket while Russia dominates the palladium side.
USGS separately reports that South African PGM production fell an estimated 9% in 2025 "owing to
declining palladium prices, higher costs associated with deep-level mining, and ongoing disruptions to
the supply of electricity," while Russian production fell 6% owing to "lower metal grades and ore
recovery, geopolitical and investor uncertainty related to the Russia-Ukraine conflict"
(USGS MCS 2026, platinum-group metals chapter).
3. Combined South Africa + Russia share and why it is the defining risk
Summing the two countries' shares of platinum and palladium mine production against the world totals
above shows South Africa and Russia together account for roughly 75% of combined
platinum-plus-palladium output on USGS 2025e figures, and independent market estimates that fold in
rhodium (concentrated almost entirely in South African UG2 ore) place the combined South
Africa-plus-Russia share of the full six-metal PGM basket at 85% or higher
(Minted Metal, Russia palladium supply analysis, Mar 2026).
No other globally traded metal complex — not cobalt, not rare earths, not lithium —
concentrates this much production in two countries whose supply is simultaneously exposed to South
African electricity-grid instability and Russian geopolitical/sanctions risk. This dual concentration,
rather than any single mine or company event, is the structural risk factor that dominates every PGM
market report.
4. US import dependence and net import reliance
The United States has essentially one domestic PGM mine complex (Stillwater/East Boulder in Montana)
and depends on imports for the balance of consumption. USGS's 2026 net import reliance figures show US
reliance at 89% for platinum and 57% for palladium in 2025, up sharply
from 85% and 34% respectively in 2024, driven by the estimated 31% decline in the value of Montana's
PGM output ($420 million in 2024 to $290 million in 2025)
(USGS MCS 2026, platinum-group metals chapter).
US import sources for 2021–24 were dominated by South Africa (49% of platinum imports, 37% of
palladium imports) and Russia (36% of palladium imports), underscoring that even the world's largest
economy is directly exposed to both poles of PGM supply concentration
(USGS MCS 2026, platinum-group metals chapter).
Current status (July 2026): South Africa's 2025 PGM output fell 9% year-on-year and
Russia's fell 6%, tightening an already concentrated supply base further rather than diversifying it.
US net import reliance for platinum rose to 89%. Watch: South African Eskom grid

The Producers: Amplats, Implats, Sibanye-Stillwater, Nornickel, and the Second Tier
A handful of companies control the overwhelming majority of primary PGM supply. In
South Africa, Anglo American Platinum, Impala Platinum, Sibanye-Stillwater, and Northam Platinum
dominate Bushveld output; Nornickel dominates Norilsk-Talnakh; and Implats' Zimplats and Mimosa
subsidiaries dominate the Great Dyke.
1. Anglo American Platinum (now Valterra Platinum)
Anglo American Platinum — rebranded Valterra Platinum following Anglo American's divestment of
its residual shareholding — reported full-year 2024 metal-in-concentrate production of
approximately 3.6 million ounces (5E+Au basis) and refined PGM production of
approximately 3.9 million ounces, with Mogalakwena as its open-pit Platreef
operation and Amandelbult its underground Merensky/UG2 operation
(Valterra Platinum (Anglo American Platinum), 2024 Annual Results).
Anglo American's own Q1 2025 production report shows the company's PGM operations produced 696,300
ounces (5E+Au metal-in-concentrate) in the quarter, down 17% year-on-year, "primarily reflecting planned
lower purchase of concentrate volumes, as well as heavy rains and widespread flooding," with the
Precious Metals Refinery's triennial stock count also depressing reported refined output
(Anglo American, Q1 2025 Production Report).
Anglo American's 2025 full-year results confirm proceeds from the sale of its residual Valterra
Platinum shareholding contributed to a reduction in net debt to $8.6 billion
(Anglo American, Full Year Results 2025).
2. Impala Platinum (Implats)
Impala Platinum's quarterly production reports show Group 6E production (Pt+Pd+Rh+Ru+Ir+Au) running
around 880,000–900,000 ounces per quarter, with managed operations at Impala
Rustenburg, Zimplats (Great Dyke), Marula, and Mimosa (Great Dyke, jointly with Sibanye-Stillwater)
contributing alongside Impala Canada's Lac des Iles palladium-dominant mine
(Implats, quarterly production report).
Within the Great Dyke, Implats' Zimplats subsidiary posted record 6E output of 646,000 ounces, up from
611,000 ounces, overtaking Mimosa as the largest single Great Dyke producer by output as Zimplats
continues deploying more than $1 billion of growth capital while generating a cumulative $5.6 billion
in revenue
(EquityAxis, Zimplats/Mimosa Great Dyke production comparison, Nov 2025).
3. Sibanye-Stillwater: the dual-continent producer
Sibanye-Stillwater is the only major PGM producer with primary operations on two continents. Its 2025
results show South African PGM operations (including Mimosa and third-party purchase of concentrate)
produced 1,797,928 4E ounces, in line with guidance of 1.75–1.85 million 4Eoz and
essentially flat year-on-year, while its US PGM operations (Stillwater/East Boulder in Montana)
produced 284,069 2E ounces, 33% lower than 2024, mainly reflecting the restructuring
that placed the Stillwater West mine on care and maintenance from the end of 2024
(Sibanye-Stillwater, 2025 Annual Financial Report).
This dual exposure means Sibanye-Stillwater's PGM output straddles the Bushveld 4E/6E reporting
convention and the Montana 2E convention within a single company, and its US operations carry a
materially different cost structure and metal mix (palladium-heavy) than its Rustenburg and Marikana
operations (platinum-heavy) — the legacy of its 2017 Stillwater Mining acquisition and 2018
acquisition of Lonmin's South African assets.
4. Northam Platinum, Royal Bafokeng Platinum, and the second tier
Northam Platinum operates three primary Bushveld mining complexes — Zondereinde (Merensky/UG2
underground), Booysendal (UG2/Merensky), and Eland (UG2) — and has grown to become South Africa's
third-largest primary PGM producer by volume behind Amplats and Implats, while Royal Bafokeng Platinum
operates the Styldrift and Bafokeng-Rasimone joint venture mines on Bushveld ground adjacent to
Implats' Rustenburg operations
(Northam Platinum, annual reports).
Outside South Africa and Zimbabwe, Vale and Glencore's Sudbury Basin nickel-copper operations in
Ontario, Canada, produce PGMs as a by-product credit, and Nornickel's Norilsk-Talnakh complex remains
the world's largest single PGM-producing operation on a combined-metal basis, with the company
confirming in its December 2025 metals-market review that "South Africa remains the main area of
weakness due to the persistent technical issues and years of underinvestment," implicitly framing
Russian output as the more resilient of the two poles
(Nornickel, Metals Market Review, 15 Dec 2025).
Current status (July 2026): Amplats/Valterra, Implats, and Sibanye-Stillwater remain
the three dominant South African primary producers; Sibanye-Stillwater's US Montana operations continue
operating at a reduced footprint following the 2024 restructuring. Nornickel's Norilsk-Talnakh output is
contracting on lower grades even as it remains the leading single-site global PGM producer.

guidance, Nornickel 2026 output guidance revisions.

The Autocatalyst Cluster: Pt, Pd, and Rh as One Demand Complex
Automotive catalytic converters are the single largest demand driver for three of the six PGMs
— platinum, palladium, and rhodium — while ruthenium, iridium, and osmium have only minor
autocatalyst exposure. WPIC data show automotive demand as the largest single platinum
end-use, forecast at 2.943 million ounces in 2026
(
Kitco News, citing WPIC Platinum Quarterly Q4 2025, 4 Mar 2026).
1. The historical platinum/palladium substitution dynamic
Diesel engines have traditionally used platinum-dominant catalyst formulations while gasoline engines
use palladium-dominant three-way catalysts, but the two metals are partial substitutes. USGS notes
that "palladium has been used as a substitute for platinum in most gasoline-engine catalytic converters
because of the historically lower price for palladium relative to that of platinum," and that "about
25% of palladium can routinely be substituted for platinum in diesel catalytic converters; the
proportion can be as much as 50% in some applications"
(USGS MCS 2026, platinum-group metals chapter).
This substitution flexibility is why platinum-for-palladium thrifting became a major theme once
palladium prices spiked above platinum in 2018–2022, and why the two metals' price relationship
remains structurally linked even though their end markets differ (diesel versus gasoline).
2. Rhodium's specialized NOx-reduction role
Rhodium's autocatalyst role is narrower but essential: it is the most effective catalyst for reducing
nitrogen oxide (NOx) emissions in three-way catalytic converters, a function platinum and palladium
cannot efficiently replicate at scale. Johnson Matthey's 2026 PGM Market Report groups platinum,
palladium, and rhodium together as "the three autocatalyst PGM," noting all three "recorded deficits in
2025, adding to significant cumulative shortfalls over the previous three years," with weak supply
— not just strong demand — identified as the common driver, as "autocatalyst recycling has
been slow to recover from a downturn during 2023–2024, while primary supply from South Africa and
North America has been eroded by rationalisation and mine closures"
(Johnson Matthey, PGM Market Report, May 2026).
3. Ruthenium, iridium, and osmium: minor and specialized autocatalyst exposure
By contrast, ruthenium and iridium have essentially negligible roles in mainstream automotive
catalysis; their demand is driven instead by electronics/hard-disk-drive and chemical catalyst uses
(ruthenium) and by spark plugs and, increasingly, hydrogen electrolysers (iridium). USGS attributes
2025's 53% ruthenium price increase and 24% rhodium price increase specifically to "decreased production
and increased demand, particularly for rhodium in the hard disk and chemical catalyst industries and
owing to the substitution of platinum in automobile catalysts"
(USGS MCS 2026, platinum-group metals chapter).
Osmium has essentially no commercial autocatalyst or mainstream industrial use at meaningful scale and
trades in a thin specialist market, distinct from the other five metals covered by JM and WPIC market
balances.
Not applicable to autocatalyst demand at scale — osmium's commercial
market is too thin to be tracked in standard PGM supply-demand balances.
4. 2026 divergence within the autocatalyst cluster
Johnson Matthey's May 2026 forecasts illustrate how differently the three autocatalyst metals can move
even while sharing the same end-use base: platinum recorded a widened deficit of 951,000 ounces in 2025
(versus 559,000 ounces in 2024) and is forecast to remain in deficit at 371,000 ounces in 2026, while
palladium's 416,000-ounce 2025 deficit is forecast to flip into a 214,000-ounce surplus in 2026, and
rhodium's 50,000-ounce 2025 deficit is forecast to flip into a 15,000-ounce surplus
(Mining Weekly, citing Johnson Matthey PGM Market Report, 14 May 2026).
The divergence stems from PGM-specific substitution economics and vehicle-mix shifts rather than any
common shock, reinforcing why analysts model the autocatalyst PGMs individually rather than as one
undifferentiated demand block.
Current status (July 2026): Platinum remains the tightest of the three autocatalyst
metals with a fourth consecutive deficit forecast for 2026; palladium and rhodium are forecast to move
into small surpluses as internal-combustion vehicle production continues its gradual decline.

Emissions Regulation: The Loading-Growth Engine Behind Autocatalyst Demand
Tighter emissions standards increase PGM loading per vehicle even when total vehicle production
is flat or falling — the single most important structural offset to the EV-substitution
narrative for platinum, palladium, and rhodium demand.
1. Euro 7 and the European tightening cycle
The European Union's Euro 7 standard extends real-driving-emissions testing conditions, lowers
particulate limits, and for the first time regulates brake and tyre particulate emissions alongside
tailpipe NOx and CO, all of which push automakers toward higher-loading, more thermally durable catalyst
formulations to maintain compliance margins across a wider range of real-world operating conditions.
Analysts covering the rhodium market explicitly link "tighter Euro 7 and China 7 emissions standards" to
locked-in rhodium demand because rhodium loading cannot be reduced without risking NOx compliance
failure
(Rzzro Intelligence, Euro 7/China 7 rhodium demand analysis, 31 May 2026).
2. China 6b and the world's largest vehicle-production base
China's China 6b standard, the domestic equivalent tier to late-stage Euro 6/early Euro 7 stringency,
governs the emissions profile of the world's largest new-vehicle production base and directly shapes
Chinese automakers' PGM loading decisions across both domestic sales and export models. Because China
is simultaneously the largest source of new autocatalyst scrap growth — Johnson Matthey notes
secondary PGM supply "benefited from strong growth in the relatively new autocatalyst recycling market
in China, where scrap volumes have been galvanised by government incentives aimed at encouraging
consumers to scrap older, more polluting vehicles"
(Johnson Matthey, PGM Market Report, May 2026)
— China 6b tightening cuts both ways: it raises loading on new vehicles while accelerating scrappage
of older, lower-loaded ones back into the recycling stream.
3. US EPA Tier 3 and India BS-VI
In the United States, EPA's Tier 3 vehicle emission and fuel standards (finalized 2014, phased in
through the early-to-mid 2020s) tightened fleet-average NOx and particulate limits, reinforcing PGM
loading requirements even as overall light-vehicle PGM demand has been supported more by fleet mix and
replacement-catalyst demand than by new regulatory tightening in the US specifically
(US EPA, All Emission Standards reference guide).
India's BS-VI standard, aligned closely with Euro 6 stringency, mandated a step-change in NOx and
particulate control for India's fast-growing vehicle fleet, requiring higher PGM-loaded catalyst systems
across both diesel and gasoline platforms and expanding the addressable base for autocatalyst PGM
demand in one of the world's largest and fastest-growing vehicle markets
(International Council on Clean Transportation, BS-VI Fuel Specification technical background).
4. Regulatory tightening as the demand-side counterweight to slowing ICE volumes
The net effect across all four jurisdictions is that per-vehicle PGM loading has generally risen even
in years when internal-combustion-engine vehicle production volumes have been flat or declining,
partially offsetting the demand headwind from EV adoption (see Section 7). WPIC's own 2026 outlook
forecasts automotive platinum demand declining only modestly (3%, to 2.943 million ounces) despite
broader EV-driven powertrain-mix shifts, "reflecting changes in vehicle production and powertrain mix"
rather than a sharp fall
(Kitco News, citing WPIC Platinum Quarterly Q4 2025, 4 Mar 2026).
Current status (July 2026): Euro 7 implementation, China 6b enforcement, and India
BS-VI compliance all continue to support per-vehicle PGM loading growth, partially cushioning the
autocatalyst PGM basket against the structural decline in global ICE vehicle share. Watch:

EV Substitution Risk: The Long-Run Threat to the Autocatalyst Basket
Battery electric vehicles use zero PGM content in their powertrains, making rising BEV
market share the single most-cited structural risk to combined platinum, palladium, and rhodium demand
— WPIC quantifies each 1-percentage-point shift from internal combustion to BEV as costing roughly
25,000 ounces of platinum and 100,000 ounces of palladium in annual
demand.
1. WPIC's quantified BEV substitution sensitivity
The World Platinum Investment Council's research states directly that "each 1% delta in LV BEV/ICE
market share equates to 25 koz of platinum and 100 koz of palladium demand annually," a relationship
WPIC uses to underpin its platinum market deficit forecasts of roughly 430,000 ounces through 2025 to
2028
(WPIC, Platinum Perspectives, May 2024).
Because palladium is disproportionately exposed to gasoline (rather than diesel) vehicles — the
powertrain segment BEVs are displacing fastest in most major markets — palladium's per-percentage-point
demand loss is roughly four times larger than platinum's on WPIC's own figures.
2. Reuters' framing of a "structural hit"
Reuters reported in March 2024 that "platinum metals face structural hit to demand from electric
vehicle revolution," citing WPIC's own projection of a persistent multi-year decline in combined
platinum autocatalyst demand as battery-electric vehicles displace internal-combustion and even
hybrid vehicle sales in key markets
(Reuters, 20 Mar 2024).
This framing has persisted through the 2025–2026 market reports even as near-term platinum
deficits have widened, illustrating that current tightness and long-run structural risk are not
contradictory: near-term deficits reflect supply erosion (Section 3), while EV substitution is a
multi-decade demand headwind operating on a slower timeline.
3. Palladium bearing the earlier and larger EV impact
Nornickel's own December 2025 metals-market review projects the palladium market to be roughly
balanced in 2025 and 2026, with total demand falling 5% (500,000 ounces) in 2025 against a 2% (200,000
ounce) supply decline — consistent with palladium absorbing EV substitution pressure earlier and
more directly than platinum, given its concentration in gasoline light-vehicle catalysts
(Rough&Polished, Nornickel palladium market outlook, 22 Jun 2026).
Heraeus's 2026 forecast similarly flags that "palladium may face a widening surplus as battery electric
vehicles gain market share," explicitly identifying BEV adoption — not oversupply from mining
— as the demand-side driver of a looser palladium balance
(Heraeus Precious Metals, Forecast 2026).
4. The offsetting factors: hybrids, loading growth, and the FCEV counter-narrative
Full EV substitution risk is partially offset by three factors: continued hybrid-vehicle sales (hybrids
retain PGM-loaded catalysts even where BEVs do not), regulatory loading growth (Section 6), and the
emergence of fuel-cell electric vehicles as a new PGM demand source (Section 8) that could, over a
long horizon, redirect some platinum demand from combustion catalysis to fuel-cell membranes rather than
eliminating it outright. Nornickel itself frames the long-run PGM demand outlook as supported "not only
by traditional industries such as the automotive industry, jewelry manufacturing and chemical
production, but also by a growing number of new applications," explicitly citing "hydrogen-related
technologies (fuel cells and electrolyzers)"
(Rough&Polished, Nornickel palladium market outlook, 22 Jun 2026).
Current status (July 2026): EV substitution remains a well-quantified, structurally
embedded long-run risk to platinum and especially palladium autocatalyst demand, but has not yet
produced a demand collapse — near-term markets remain supply-constrained rather than
demand-oversupplied. Watch: global BEV market-share trajectory by region, WPIC and JM
updated substitution-sensitivity estimates.

Hydrogen Economy Exposure: Platinum's Fuel Cells, Iridium's Electrolyser Bottleneck
Platinum and iridium carry the PGM basket's clearest exposure to the hydrogen buildout
— platinum as the catalyst in proton-exchange-membrane (PEM) fuel cells, and iridium as the anode
catalyst in PEM electrolysers, where it faces the most severe single-metal supply bottleneck in the
entire PGM basket.
1. Platinum demand from fuel-cell electric vehicles
WPIC's fuel-cell-vehicle demand modelling estimates that if annual FCEV production reaches roughly
700,000 units using loadings comparable to the Hyundai Nexo, platinum demand from that segment alone
would approach 1 million ounces annually, with a policy-driven adoption scenario reaching almost 4
million ounces per year by 2040 and a commercially-enhanced adoption scenario reaching almost 6.7
million ounces per year by 2040
(CME Group, citing WPIC fuel-cell-vehicle platinum demand analysis).
WPIC's 2026 outlook already credits part of the near-term rebound in platinum industrial demand to
"growth in chemical and hydrogen applications," alongside renewed glass-sector capacity expansion
(Kitco News, citing WPIC Platinum Quarterly Q4 2025, 4 Mar 2026).
2. Iridium's PEM electrolyser bottleneck
Iridium's role as the oxygen-evolution-reaction catalyst at the PEM electrolyser anode is the most
acute single-metal constraint anywhere in the PGM complex: annual global iridium supply is estimated at
roughly 7.5 tonnes, and Johnson Matthey has separately estimated that only around 1.5–2 tonnes per
year could realistically be freed up for the hydrogen electrolyser industry after accounting for
existing uses in spark plugs, crucibles, and other established applications
(industry technical presentation on iridium demand modelling for PEM electrolysis).
Peer-reviewed modelling published in the International Journal of Hydrogen Energy examines whether
"iridium demand [is] a potential bottleneck in the realization of large-scale" PEM water electrolysis
capacity, concluding that current specific loadings (roughly 0.33 g/kW under 2020 targets) would
require substantial reductions to avoid iridium supply constraining electrolyser rollout at gigawatt
scale
(International Journal of Hydrogen Energy, iridium bottleneck analysis).
3. Loading reduction R&D as the industry's central response
Because iridium supply is essentially fixed by PGM co-production economics (it is recovered mainly as a
minor by-product of platinum and palladium mining, not mined independently), the hydrogen industry's
primary response has been catalyst-loading reduction rather than supply expansion. US Department of
Energy H2NEW consortium targets call for iridium loading of 0.4 mg/cm² by 2026, and Rice University
researchers announced in October 2025 an iridium-stabilized ruthenium oxide catalyst using "just
one-sixth as much iridium as conventional systems" while maintaining performance over more than 1,500
hours of continuous operation, explicitly framing the innovation as "addressing one of the biggest
economic and supply chain bottlenecks in the hydrogen economy"
(Rice University News, 13 Oct 2025).
Separate modelling published by Johnson Matthey researchers found that implementing closed-loop
iridium recycling by 2035 "would increase the installed [electrolyser] capacity in 2050 by
approximately 2.7 times compared to a scenario with no iridium recycling"
(Johnson Matthey, Perspectives on current and future iridium demand for PEM water electrolysis).
4. Iridium price behaviour reflects hydrogen-market sentiment more than physical scarcity
USGS's 2026 chapter notes that "the price decrease for iridium may have been affected by increased
production and the waning of investor enthusiasm in the hydrogen power market" — the only PGM to
record a price decline in 2025 even as ruthenium, platinum, rhodium, and palladium all rose
(USGS MCS 2026, platinum-group metals chapter).
Yet Heraeus's Precious Appraisal reported iridium rising 9% in a single week to $6,500/oz in January
2026, "marking its highest level since June 2021," after "spend[ing] much of 2025 underperforming other
PGMs," illustrating how sharply iridium sentiment swings between hydrogen-optionality enthusiasm and
skepticism
(Heraeus Precious Appraisal No. 2, 19 Jan 2026).
Current status (July 2026): Johnson Matthey's 2026 PGM Market Report flags ruthenium
and iridium both in deficit "amid rising demand from the data storage and energy transition sectors"
(
Mining Weekly, 14 May 2026),
while iridium price sentiment continues to oscillate with hydrogen-policy news flow rather than tracking
physical fundamentals cleanly.
Watch: DOE H2NEW loading-reduction milestones, global
electrolyser capacity build-out announcements, iridium recycling-rate progress toward DOE's 99% target.

The Refining Oligopoly: Four to Six Facilities Control the World's PGM Metal
Mine-to-metal PGM refining is one of the most concentrated processing chains of any traded
metal complex. Johnson Matthey, Umicore, BASF/Heraeus, Nornickel, and Amplats' own Precious
Metals Refinery together account for the large majority of the world's PGM base-metal-separation and
refining capacity, and the smelter-to-converter-to-refinery chain from mined ore to saleable metal
typically takes four to six months.
1. The Western refining leaders: Johnson Matthey and Umicore
Johnson Matthey (United Kingdom) is both the world's leading PGM market-data publisher and one of its
leading refiners and fabricators, running dedicated PGM refineries feeding its market-report analytical
franchise. Umicore's Precious Metals Refining division in Hoboken, Belgium is one of the world's largest
integrated precious- and base-metal recycling and refining complexes, processing complex secondary
feeds including autocatalyst scrap, electronics, and industrial residues, with Umicore describing itself
as recovering "17 different metals" from as many as 200 different input material types
(Umicore, Precious Metals Refining division overview).
2. The German cluster: BASF and Heraeus
BASF and Heraeus — both headquartered in Germany — are major PGM refiners in their own
right and, in February 2022, agreed to form a joint venture combining their precious-metal services and
recycling activities specifically "to offer world-class" scale in this space, reflecting how even large
individual refiners have sought consolidation to compete with the largest integrated players
(BASF, joint venture announcement with Heraeus, 11 Feb 2022).
BASF separately announced in May 2021 that it was expanding its global PGM refining capacity "further
driving circular economy" objectives around catalyst recycling
(BASF, PGM refining capacity expansion announcement, 12 May 2021).
Heraeus separately publishes the widely followed Precious Appraisal and Platinum
Standard market reports through its Hanau, Germany precious-metals unit.
3. Japan's specialist refiners: TANAKA and Furuya Metal
In Japan, TANAKA Holdings operates Nippon PGM Co., a dedicated group company focused specifically on
platinum-group-metal recycling, refining, and fabrication
(TANAKA, Nippon PGM Co. group company profile).
Furuya Metal, a smaller but highly specialized Japanese refiner, generates the majority of its revenue
from its "Fine Chemicals/Recycling" segment — up 30.1% year-on-year to ¥26.3 billion in its
latest fiscal year — manufacturing high-purity iridium and other precious-metal compounds for
organic-EL displays and providing industrial precious-metal recycling and refining services
(Furuya Metal, EDINET securities report).
Furuya Metal's recycling and refining division is described directly on its own corporate site as a
core service line
(Furuya Metal Co., Ltd., Recycling and Refining).
4. Russia and South Africa's captive refining capacity
Nornickel operates its own integrated PGM refining capacity in Russia, refining its Norilsk-Talnakh
concentrate domestically rather than exporting unrefined material, giving Russia a fully captive
mine-to-metal chain largely insulated from Western refining bottlenecks. Anglo American Platinum's
Precious Metals Refinery in Rustenburg, South Africa performs the equivalent function for Bushveld
concentrate, and Anglo American's own production reports show refined output swinging with the
refinery's periodic triennial stock count — a physical inventory reconciliation exercise that
temporarily depresses reported refined production every three years, as seen in the 30% year-on-year
refined-production decline reported for Q1 2025
(Anglo American, Q1 2025 Production Report).
Current status (July 2026): PGM refining capacity remains concentrated in a small
number of facilities across the UK, Belgium, Germany, Japan, Russia, and South Africa; no significant
new-entrant refining capacity has emerged to challenge this structure, and long lead times for capacity
expansion (multi-year permitting and construction for smelter/converter/refinery trains) mean the
refining bottleneck is structurally durable rather than a short-term supply hiccup. Watch:

Recycling: The PGM Basket's Most Successful Circular-Economy Story
Recycling meets a larger share of annual PGM demand than for almost any other metal complex.
Johnson Matthey's own circularity analysis finds that recycling met 57% of gross 2024 demand
across platinum, palladium, rhodium, ruthenium, and iridium combined — ranging from 47% for
palladium to 66% for iridium.
1. Johnson Matthey's circularity data: metal-by-metal recycling shares
| Metal | Reported net market demand 2024 (t) | Estimated total recycling (t) | Recycling share of gross demand |
|---|
| Platinum | 233 | 355 | 65% |
| Palladium | 302 | 184 | 47% |
| Rhodium | 33 | 37 | 61% |
| Ruthenium | 34 | 42 | 55% |
| Iridium | 7 | 14 | 66% |
| Total | 610 | 631 | 57% |
Source: Johnson Matthey, The PGMs: a circularity success story.
Johnson Matthey states that PGMs are "among the most highly recycled materials in the world, with
recycling rates in some applications exceeding 95%," and that "almost 60% of PGM used on new products
every year is now recycled metal, from both the open and closed loops"
(Johnson Matthey, The PGMs: a circularity success story).
2. Autocatalyst recycling: the dominant recovery channel
Market research estimates that recycling accounts for approximately 32% of total global PGM supply
across platinum, palladium, rhodium, and minor PGMs, equivalent to roughly 7.5–8.0 million troy
ounces annually, with autocatalysts contributing roughly 58% of all secondary PGM material and holding
a 58.4% source-share of the broader PGM recycling market, valued at $8.6 billion in 2025 and projected
to reach $16.2 billion by 2034
(Dataintelo, Global Recycling of Platinum Group Metals Market Research Report).
USGS's recycling estimate for the US market alone shows approximately 140,000 kilograms of combined
palladium and platinum recovered globally from new and old scrap in 2025, including about 50,000
kilograms of palladium and 8,600 kilograms of platinum recovered from US automobile catalytic
converters specifically
(USGS MCS 2026, platinum-group metals chapter).
3. The 2025 recycling recovery and its role in easing autocatalyst deficits
Johnson Matthey's 2026 PGM Market Report identifies autocatalyst recycling recovery as one of the
central supply-side developments narrowing the platinum, palladium, and rhodium deficits: "strong PGM
prices continue to support a recovery in autocatalyst recycling," with "automotive recycling…
boosted by high PGM prices which are helping to accelerate catalyst scrap through the collection and
processing network"
(Johnson Matthey, 2026 PGM Market Report summary).
The same report forecasts double-digit growth in autocatalyst recycling for 2026, helping offset an
expected drop in Russian mine production, with China identified as a fast-growing new source of scrap
volume, "galvanised by government incentives aimed at encouraging consumers to scrap older, more
polluting vehicles"
(Johnson Matthey, PGM Market Report, May 2026).
4. The specialist separator-refiner network and non-autocatalyst recycling
Beyond mainstream autocatalyst scrap, specialized separator refiners handle industrial catalyst,
electronics, and jewelry-scrap PGM recovery: BASF's Seneca, South Carolina refining site, Umicore's
Hoboken, Belgium complex, and Johnson Matthey's Brimsdown, UK facility are among the network of Western
refiners equipped to separate mixed PGM streams into individually saleable metal
(Umicore, Precious Metals Refining division overview).
Electronics recycling is a comparatively minor but growing recovery channel specifically for ruthenium
and iridium, which see industrial use in hard-disk-drive media and specialty electronic components,
distinct from the autocatalyst-dominated recovery path for platinum, palladium, and rhodium.
Current status (July 2026): Recycling supply growth, not new mine supply, is the
primary driver narrowing the platinum, palladium, and rhodium deficits in 2026 forecasts; WPIC's Q4 2025
data show 2026 total platinum supply rising 2% "on the back of recycling supply growth alone," with
recycling volumes forecast up 10% to 1,827,000 ounces
(
WPIC, Platinum Quarterly Q4 2025 press release).

Market Data and Reference: The Reports That Set the PGM Agenda
Four institutions publish the primary-source data the entire PGM market relies on:
Johnson Matthey's semi-annual PGM Market Report, the World Platinum Investment Council's quarterly
Platinum Quarterly, Heraeus's weekly Precious Appraisal and annual Platinum Standard, and Metals Focus's
PGM Focus.
1. Johnson Matthey PGM Market Report
Johnson Matthey publishes its PGM Market Report
semi-annually (May and November), providing detailed supply-demand balances for platinum, palladium,
rhodium, ruthenium, and iridium individually, plus historical demand and supply data by region available
for download
(Johnson Matthey, PGM market data downloads).
The May 2025 edition forecast "the platinum market… to record a significant supply shortfall for
a third consecutive year"
(Johnson Matthey, 2025 PGM Market Report publication announcement),
while the May 2026 edition extended that to a fourth consecutive platinum deficit alongside forecast
surpluses for palladium and rhodium
(Johnson Matthey, 2026 PGM Market Report publication announcement).
2. WPIC Platinum Quarterly
The World Platinum Investment Council publishes Platinum Quarterly
each quarter, providing the most granular platinum-specific supply-demand data available, broken down
by mine supply, recycling supply, automotive, jewelry, industrial, and investment demand. Its March 2026
release forecast platinum's fourth consecutive annual deficit at 240,000 ounces for 2026, following a
record 1,082,000-ounce deficit in 2025, with cumulative deficits since 2023 approaching 3 million
ounces and above-ground stocks projected to fall to just over four months of global demand cover
(WPIC, Platinum Quarterly Q4 2025 press release, 4 Mar 2026).
3. Heraeus Precious Appraisal and Platinum Standard
Heraeus Precious Metals publishes the weekly Precious Appraisal
covering near-term price action across gold, silver, and all traded PGMs, and the annual
Platinum Standard, now in its ninth year in collaboration with SFA (Oxford), offering
"evaluation and outlook on upcoming trends in the PGM industry" with contributions from industry-expert
authors
(Heraeus Precious Metals, The Platinum Standard 2026).
Heraeus's annual Precious Metals Forecast (published each November/December for the following
year) gives specific dollar price ranges for each PGM — its most recent forecast projected
platinum at $1,300–$1,800/oz, palladium at $950–$1,500/oz, rhodium at $6,000–$9,000/oz,
ruthenium at $600–$975/oz, and iridium at $3,800–$5,150/oz
(Heraeus Precious Metals, Precious Metals Forecast 2026).
4. Metals Focus PGM Focus and USGS MCS as the government benchmark
Metals Focus publishes PGM Focus as its dedicated platinum-group-metals research product,
joining Johnson Matthey, WPIC, and Heraeus/SFA (Oxford) as the fourth major independent commercial
research house tracking the PGM basket in comparable analytical depth
(Metals Focus).
Underpinning all of these commercial reports is the US Geological Survey's own annual
Mineral Commodity Summaries, Platinum-Group Metals chapter,
published each February, which provides the earliest comprehensive government-sourced production,
reserve, price, and trade dataset each year and is the primary-source anchor most other PGM commentary,
including this deep-dive, ultimately cites back to.
Current status (July 2026): All four major commercial PGM research houses (Johnson
Matthey, WPIC, Heraeus/SFA Oxford, Metals Focus) remain active and continue publishing on their
established schedules; USGS MCS 2026 (version 1.3, published May 2026) remains the most current
government dataset. Watch: Johnson Matthey's November 2026 PGM Market Report update,

Investment Vehicles: Physical ETFs, Equities, and the Post-Sanctions GDR Gap
Investors can access the PGM basket through physically-backed ETFs, direct producer equities, or
diversified precious-metals baskets — but direct exposure to Russian PGM supply through
listed securities has been effectively closed since the escalation of Western sanctions.
1. Physical ETFs: PPLT and PALL
The abrdn Physical Platinum Shares ETF (NYSE Arca: PPLT) and abrdn Physical Palladium Shares ETF (NYSE
Arca: PALL) are the leading US-listed physically-backed vehicles for direct platinum and palladium price
exposure, each holding allocated physical metal rather than derivatives
(TradingView, abrdn Physical Platinum Shares ETF (PPLT);
Yahoo Finance, abrdn Physical Palladium Shares ETF (PALL)).
Both funds saw substantially increased investor attention through 2025 as platinum and palladium prices
outperformed gold; one market commentary specifically highlighted "Platinum, Palladium ETFs Are Stealing
The Spotlight In 2025" amid the metals' sharp price gains
(Webull, Platinum/Palladium ETF commentary, 2025).
For investors seeking combined exposure across the wider precious-metals complex including PGMs, the
abrdn Physical Precious Metals Basket Shares ETF (GLTR) held $2.92 billion in assets under management as
of early 2026
(ETF Central, "There's an ETF for That? Platinum and Palladium," 23 Jan 2026).
2. Direct producer equities: SBSW and the South African majors
Sibanye-Stillwater trades as SBSW on the New York Stock Exchange and SSW on the Johannesburg Stock
Exchange, offering direct equity exposure to a dual-continent PGM producer spanning both the Bushveld
Complex and the Stillwater Complex
(ShareNet, Sibanye-Stillwater 2025 annual report filing notice).
Anglo American Platinum (now Valterra Platinum), Impala Platinum, and Northam Platinum all trade on the
Johannesburg Stock Exchange and provide equivalent direct exposure to South African PGM production,
each carrying differentiated operating leverage, cost structures, and commodity-mix exposure across the
4E/6E basket.
3. Nornickel GDRs: the pre-sanctions access route that has effectively closed
Prior to 2022, international investors commonly accessed Nornickel exposure through London-listed
Global Depositary Receipts, offering indirect equity exposure to the world's largest single-site
combined nickel-copper-PGM producer. Following the escalation of Western sanctions on Russia after
February 2022, London Stock Exchange trading in Nornickel GDRs was suspended, and subsequent US
regulatory scrutiny — including the Section 232 and anti-dumping investigations into Russian
palladium that Heraeus notes remain outstanding as of early 2026
(Mining Weekly, citing Heraeus market commentary, 12 Jan 2026)
— has left direct Western portfolio access to Nornickel's PGM output effectively closed for most
institutional investors, even as the company continues normal physical production and sales through
non-Western channels.
Not applicable in practice for most Western retail/institutional
investors — Nornickel GDR access has not meaningfully reopened as of mid-2026.
4. Diversified PGM basket exposure and derivatives access
Beyond single-metal ETFs and direct equities, investors can gain diversified basket exposure through
multi-metal precious-metals funds (such as GLTR) or through exchange-listed futures and options.
Heraeus reported in November 2025 that the China Securities Regulatory Commission approved the launch
of platinum and palladium futures and options contracts on the Guangzhou Futures Exchange, accepting
both sponge and ingot forms for physical delivery — "a world-first among major futures exchanges"
— a development Heraeus expects will "strengthen domestic hedging capability and improve price
discovery" and over time "broaden market participation, increase liquidity and establish an onshore
pricing reference for platinum group metals"
(Heraeus Precious Appraisal, reported via industry video summary, 18 Nov 2025).
Current status (July 2026): PPLT and PALL remain the primary US-listed physical PGM
ETF vehicles; SBSW and the JSE-listed South African producers remain the main direct equity route;
Nornickel GDR access remains effectively closed to most Western investors amid unresolved US Section
232/anti-dumping proceedings on Russian palladium. Watch: outcome of the US Section 232
and anti-dumping investigations into Russian palladium, Guangzhou Futures Exchange PGM contract
liquidity build-out.

Recent Structural Context: From the Palladium Boom to the Platinum Deficit Era
The PGM basket has swung through three distinct structural regimes since 2020: a
palladium price boom and correction (2020–2022), a persistent multi-year platinum deficit driven
by South African and Russian supply erosion (2023–2026), and an emerging iridium
"green-hydrogen-optionality" narrative whose price impact has proven far more volatile than fundamental.
1. 2020–2022: the palladium record-high era and its correction
Palladium traded at record levels through 2021–2022, with USGS data showing the average annual
US price at $2,419.18/oz in 2021, driven by tight gasoline-autocatalyst demand and constrained South
African and Russian supply during pandemic-era disruptions. Palladium then began a sustained
correction, falling to $2,133.81/oz in 2022, $1,351.66/oz in 2023, and $994.90/oz in 2024 — a
decline of roughly 59% from the 2021 peak — as EV substitution pressure (Section 7) and eased
supply combined to unwind the boom
(USGS MCS 2026, platinum-group metals chapter).
2. 2024–2026: the WPIC platinum deficit thesis takes hold
The cumulative deficit accumulated since 2023 is approaching 3 million ounces by WPIC's own count, with
above-ground stocks projected to fall to roughly 2.613 million ounces by end-2026, equivalent to just
over four months of global demand cover — a historically thin buffer that underpins the deficit
thesis's persistence in investor and analyst commentary through mid-2026
(WPIC, Platinum Quarterly Q4 2025 press release, 4 Mar 2026).
3. Rhodium's boom-bust round trip
Rhodium's own price history is more volatile than platinum's or palladium's: USGS data show the average
annual price collapsing from $20,254.10/oz in 2021 to $15,585.00/oz in 2022, $6,660.58/oz in 2023, and
$4,660.44/oz in 2024 — a roughly 77% peak-to-trough decline — before rebounding an estimated
24% in 2025 to around $5,800/oz as hard-disk-drive and chemical-catalyst demand tightened alongside
constrained South African supply
(USGS MCS 2026, platinum-group metals chapter).
4. 2025–2026: the iridium green-hydrogen-optionality narrative
Iridium's price behaviour through the 2025–2026 period illustrates how a genuine long-run
structural bottleneck (Section 8) can trade on sentiment swings that diverge sharply from near-term
fundamentals. USGS attributes the estimated 9% decline in iridium's 2025 average price specifically to
"increased production and the waning of investor enthusiasm in the hydrogen power market"
(USGS MCS 2026, platinum-group metals chapter),
yet Heraeus reported iridium jumping 9% in a single week to a five-year high of $6,500/oz in mid-January
2026 after "spend[ing] much of 2025 underperforming other PGMs"
(Heraeus Precious Appraisal No. 2, 19 Jan 2026),
before Johnson Matthey's May 2026 report again flagged iridium in deficit on rising data-storage and
energy-transition demand
(Mining Weekly, 14 May 2026).
This whipsaw — declining average-price trend even as spot prices spike on hydrogen headlines
— is emblematic of how thinly traded and sentiment-driven the smallest PGMs remain relative to
platinum and palladium.
What the structural context shows: unlike single-shock critical-minerals stories
(export bans, single-mine closures), the PGM basket's defining 2020–2026 narrative arc is a slow
multi-year supply erosion in South Africa and Russia colliding with divergent, metal-specific demand
trajectories — palladium falling on EV substitution even as platinum tightens on deficit, and
iridium swinging on hydrogen sentiment even as ruthenium quietly posts the basket's largest 2025 price
gain on data-storage demand. No single catalyst explains the basket; six overlapping metal-specific
stories do.
Current status (July 2026): Platinum remains in its fourth consecutive annual deficit
year; palladium and rhodium are forecast to move to small surpluses in 2026; ruthenium and iridium
remain in deficit on data-storage and energy-transition demand per Johnson Matthey's latest report.
