Catastrophe Bonds Face Their Biggest Test as Climate Risk Reprices

The catastrophe-bond market has drawn a new class of buyers as spreads remain attractive and issuance expands across wind, earthquake and aggregate-loss protection.

Managers point to low correlation with public assets, but the central question has shifted: can historical models adjust quickly enough when the baseline for insured losses is changing?

Last season's experience pushed investors to distinguish clean event risk from structures that retain exposure across several seasons. Secondary-market liquidity remains firm, yet pricing now varies sharply by trigger, geography and attachment point.

For buyers, expected loss is only one part of the calculation. Rebuilding costs, insurance penetration and the time required to settle modeled-loss contracts can materially alter realized returns.

“Every renewal now carries a different distribution of risk, even when the headline peril appears unchanged.”
