Mining Risk Review 2026: How mining & metals companies can optimize international liability programs

The international liability market for mining has continued to soften over the past 12 months, trending in line with the dynamics of the broader general liability market. This has been driven by an increase in capacity available, with several carriers entering or reentering the mining liability market and others relaxing restrictions around tailings storage facilities (TSFs), underground exposures and certain geographies.

While concerns around social inflation, prior loss deterioration and insufficient reserving persist, a surplus of available capacity is driving competition and downward pressures on rates.

“For many liability insurers, mining remains an attractive sector due to the comparatively high rate-on-line of placements compared to other, lower hazard occupancies”, Matt Clissitt, Managing Director & Head of Liability, GB, Willis Natural Resources.

For well risk-managed mining clients with little-to-no prior loss activity, mid-single digit rate reductions are the typical starting point, with larger decreases available on smaller, less complex programs where sufficient capacity is available to place the program limit multiple times over. However, caution remains for those placements with exposure in the U.S., with insurers looking to ringfence and rate the premium associated with U.S. exposures separately.

How much international liability capacity is available to mining companies?

Published global international mining liability capacity is estimated to have increased for an eighth successive year, now exceeding $1.2 billion, surpassing levels recorded before the Brumadinho tailing dam failure.

But while capacity has increased, the broader market dynamics have not returned in parallel. Placements are more widely syndicated across a greater number of carriers, underwriting has become more technical and risk engineering-led (particularly in relation to TSFs) and the underlying market pricing is at a higher, albeit more sustainable, level.

Mining liability insurers are focusing on two key risks

1. Despite the absence of a major catastrophe mining liability loss impacting the global market for several years, primary loss activity from more traditional worker-injury style claims persists, leading to continued underwriting scrutiny.
2. TSFs remain an underwriting concern for liability underwriters. Mining companies need to demonstrate current, high-quality risk engineering information and a clear strategy for tailings management and alignment with the Global Industry Standard on Tailings Management (GISTM), which is widely regarded as the best-in-class standard for tailings governance and management.

Across the mining and metals sector, growing scrutiny of sustainable environmental management in mining has also driven increased interest in environmental impairment liability (EIL) as a complementary risk transfer mechanism for environmental liabilities. EIL policies can be broad and offer several coverage benefits beyond those available under traditional general liability, and property damage and business interruption policies.

Is now the right time to reassess and structure a mining liability program?

Against a backdrop of ample capacity, mining companies have an opportunity to look beyond immediate premium savings and reassess:

• Program limits and attachment points
• Retention levels
• Insurer participation and panel structure
• The intersection of international liability coverage with other products and solutions
• The overall resilience of the placement strategy

These insights will be particularly valuable where an existing program was created in harder market conditions where choice was scarcer and typically bound by limited capacity.

“While stronger balance sheets are generally driving a trend towards higher retentions, insureds now have greater flexibility to structure programs to better meet their risk transfer strategy”, Raj Vora, Director, Liability, GB, Willis Natural Resources.

Translating soft market conditions into longer-term resilience

The international liability market for mining continues to be favorable for well-risk-managed mining companies, with surplus capacity driving competition and downward pressure on rates. This presents an opportunity to not only achieve pricing efficiencies but also to optimize the program structure, insurer composition and the overall resilience of the placement.

The key challenge for buyers today is no longer how to access capacity, but how best to optimize its deployment.
