Parametric Trigger

A cat bond or insurance trigger based on a physical measurement rather than actual losses — enabling fast settlement.

A parametric trigger pays out based on a measurable physical or financial index — wind speed at a specific weather station, earthquake magnitude at a specific depth, a financial index crossing a threshold — rather than the cedant's actual losses. This removes the need for loss assessment, enabling settlement in days rather than months.

The defining characteristic is objectivity: the trigger either occurs or it doesn't, based on publicly verifiable data from authoritative sources (NOAA, USGS, satellite systems). This makes parametric structures ideal for capital markets distribution — investors don't need to audit claims.

The trade-off is basis risk. A parametric trigger designed to approximate a cedant's losses will always have some imperfection. The best-designed parametric structures use multiple measurement points and sophisticated index methodologies to minimise basis risk while preserving settlement speed.

Example usage

The parametric trigger uses a weighted average of peak gust wind speeds from 12 NOAA weather stations across the Carolinas, paying out $25m per 10 mph increment above 100 mph.
