How to Insure a Metal: The Risk Roadmap

Insurance is how the metals industry transfers risk that it cannot absorb on balance sheet — from a single FIBC of cobalt hydroxide in transit to a tailings storage facility (TSF) that, if it fails, can write a US$ multi-billion loss like Brumadinho. This page distils the full lifecycle into five phases and covers every line of business a metals operator typically needs: Property All-Risks, Construction (CAR/EAR), Operational Mining, Tailings, Business Interruption, Machinery Breakdown, Marine Cargo, Stock Throughput, Warehouse Legal Liability, Specie, Product Liability, D&O, Environmental Impairment, Trade Credit, Political Risk, Marine Hull, Surety Bonds, Cyber, Crime and K&R. All references are to primary sources — Lloyd's, IUMI, IMIA, ICC, GISTM, Swiss Re sigma.

03Lines of business — pick a cover

The metals industry is insured by ~20 distinct lines of business, each with its own market, wording and exclusions. The default ICC Glossary tab "Insurance & Risk" lists every term used below.

Coverage explorer 19 lines available
Showing wording for: Property All-Risks (PAR) · Market: Lloyd's of London

PAR — Property All-Risks (operating sites)

"All-risks" really means "all risks not specifically excluded". Insures direct physical loss or damage to plant, equipment, stockpiles, buildings and infrastructure at named locations. Sub-limits typically apply to flood, earthquake, machinery breakdown, debris removal, expediting expense.

How it is rated

Rate-on-line driven by total insurable values (TIV — replacement cost not market value), COPE data (Construction, Occupancy, Protection, Exposure), claims history, distance to fire-fighting infrastructure, NatCat zone (PML / EML modelled in RMS / AIR). Typical deductible: 2–10× retained working layer.

04Detailed phases

Phase 1Pre-bind — risk identification (2–12 weeks)

Identify everything that could go wrong across the operation — not only the dam. The metals operator's risk register typically maps to ~20 lines of business: site hazards, plant breakdown, supply-chain interruption, in-transit loss, warehouse bailee exposure, product liability, environmental impairment, financial counterparty failure, political event, cyber outage, fidelity and security. Each line has its own evidence pack the underwriter expects.

Phase 2Underwriting & placement (4–10 weeks)

The broker assembles a submission pack and goes to market. For complex risks the broker chooses a "lead" underwriter (the syndicate or company that writes the largest line and dictates wording) and follows with co-insurers and reinsurers. Lead market for metals: London (Lloyd's syndicates, London company market), Munich, Zurich, Bermuda, Singapore.

Phase 3Bind & in-force monitoring (12 months)

The policy is live. Several lines require continuous in-force activity to remain valid: monthly stock declarations for Stock Throughput, quarterly TSF compliance certificates for any TSF cover, sanctions re-screening for Trade Credit, payroll declarations for Employers' Liability, sales declarations for Product Liability. Failure to deliver these on time can void cover or trigger an underwriter audit.

Phase 4Loss event response (0–24 months)

From the moment a loss happens, the clock starts. The notification window is typically 24–72 hours for material losses; faster (immediate) for events that risk public-safety attention. The first hours determine whether the claim can be defended, paid promptly, or denied entirely. See the dedicated How to Claim page for the full claim lifecycle.

Phase 5Settlement & renewal (6–36 months)

Final adjustment produces an indemnity figure; the insurer pays, less any deductible, less any sub-limit, and subject to any policy condition. The insurer is subrogated into the insured's rights against third parties (carrier, contractor, supplier) to the extent of payment. Renewal underwriting then reflects the loss experience and any risk-improvement work completed.

05Market structure — who underwrites metals

Lloyd's of London

Subscription market of ~50 active syndicates writing metals, mining, marine cargo, hull, specie, political risk, D&O, cyber. The lead syndicate sets terms; the following market signs the same slip at the same price. Stamping via Market Reform Contract (MRC).

IUMI — marine cargo & hull

International Union of Marine Insurance — the global trade body for ocean marine, river marine, energy and offshore marine. Publishes annual statistics and the Cargo Marine Risk Survey; sets thought leadership on container fires, BI in cargo, STP.

Source: IUMI

IMIA — engineering / mining

International Association of Engineering Insurers — Working Group Papers (WGPs) are the de facto reference for CAR/EAR, OM, MB and TSF underwriting. WGP 117 (2022) is the current mining risk-engineering template; WGP 72 covers Machinery Breakdown.

Source: IMIA WGPs

LMA — wording authority

Lloyd's Market Association — issues the wording library (Institute Cargo Clauses, Institute Hull Clauses, JCC war clauses, LMA property and casualty wordings). Updates published continuously; older wordings remain available for legacy policies.

ICC — Incoterms & trade-credit

International Chamber of Commerce — publishes Incoterms (2020 edition current), the Uniform Customs and Practice for Documentary Credits (UCP 600), and the Trade Register Report on global trade-finance loss experience.

Captives & mutuals

Many of the world's largest metals groups self-insure significant retention through wholly-owned captive insurers, often domiciled in Bermuda, Cayman, Guernsey or Vermont. Industry mutuals (e.g. Oil Insurance Ltd for energy; smaller cluster for mining) pool risk across operators in the same line.

Reinsurance market

Munich Re, Swiss Re, Hannover Re, SCOR, Berkshire Hathaway, RGA, Lloyd's syndicates. Most metals primaries cede 60–90% of large risks via treaty (automatic) and facultative (single-risk) placements. Retro market and ILS capacity supply the apex.

Multilaterals (PRI)

MIGA (World Bank), DFC (US), EBRD, ADB, AfDB, IDB, Sinosure, ECGD/UKEF and other ECAs underwrite political risk and trade credit for cross-border mining and metals investment. Often tenors and capacity unavailable in private market.

Source: MIGA

P&I clubs (marine liability)

13 International Group clubs mutually own General Excess of Loss reinsurance; vessel owners obtain liability cover (pollution, crew, third-party). Metal cargo claims subrogate via the carrier's P&I club — the apex of marine liability capacity.

06Typical exclusions & post-loss carve-outs

TSF carve-outs (post-Brumadinho)

Many global reinsurers fully exclude TSF from Operational Mining; standalone TSF cover requires GISTM compliance, ITRB sign-off, ANM 13/2019 compliance in Brazil, dam-break analysis, sub-limit (US$ 50–250m), high deductible. Upstream-method dams largely uninsurable in the private market.

Terrorism & political violence

Excluded from standard PAR; covered through standalone Terrorism (LMA T3 / T3A wordings) and Political Violence (LMA PV wordings). State terrorism schemes (Pool Re UK, TRIA US, Spain Consorcio) provide reinsurance to private market in many jurisdictions.

Pandemic / communicable disease

Universal exclusion from BI since COVID-19. UK FCA Supreme Court test case (Jan 2021) settled the existing-wording dispute; subsequent wordings explicitly exclude communicable disease and government order. Standalone parametric covers exist but are narrow.

Cyber war exclusion (LMA 5400 series)

From 2023, all Property and Cargo wordings carry a state-backed cyber exclusion (LMA 5400/5401/5402/5403). State-attributed cyber events (whether or not declared war) are excluded; attribution is the contentious clause — typically based on government statement or industry consensus.

Climate & ESG carve-outs

Growing list of "ESG conditions precedent": coal-bearing assets excluded by ~30 major (re)insurers; thermal coal mining and coal-fired generation outright unwritten by many. Lloyd's 2022 ESG market framework; UN-convened Net-Zero Insurance Alliance (paused in 2023 but principles persist).

Sanctions clause (universal)

Every commercial policy carries a sanctions limitation and exclusion clause (LMA 3100 / 3200 series): no cover, payment or service if doing so would expose the (re)insurer to a sanction under UN, EU, UK, US (OFAC) law. A material change in the sanctions list during the period of insurance can suspend cover for affected exposures.
