A what‑if from the future

What if one mega-hurricane wipes out a swath of catastrophe bonds?

A mega-hurricane wiping out cat-bond principal vaporizes ILS-fund capital and reinsurance capacity, hardening property rates — a sector-contained insurance shock, not a grain-supply event. Rhymes with Hurricane Ian (2022), which triggered cat-bond losses and a hard 2023 reinsurance renewal. The roots wrongly pull in climate_supply, dragging wheat/corn crop-stress into a wind/insurance event — a hurricane does not lift grains; the correct map is a credit/risk shock plus geopolitical/no-ag.

What it would mean

If this plays out, it is a risk-off shock. A single mega-hurricane triggers principal losses across a swath of catastrophe bonds, vaporizing ILS-fund capital and reinsurance capacity. The trigger decomposes into signed root‑shocks — Credit spreads ▲ · Risk appetite ▼ · Financial conditions ▲ — which propagate through our causal graph to the markets below.
