1. Capacity and competition
WTW's Mining Risk Review 2026, published Oct. 28, found that abundant capacity and intense competition are driving mining insurance rate reductions. Global liability capacity exceeds US$1.2 billion after eight consecutive years of growth, while property placements are frequently oversubscribed.
2. Risks for miners
The report urges miners to optimize insurance programs under favorable conditions as interconnected risks increase potential disruption. It identifies supply chain concentration as a strategic priority, notes that greater technology integration is increasing potential cyber losses, and says tailings governance remains central to underwriting.
