PARAMETRIC wind INSURANCE
Your client is hit by winds, not by a category.
Most parametric hurricane triggers pay based on storm category and where its centre crosses a polygon. Neither tells you what wind speed your client's location actually experienced. That's where payouts disconnect from damage, and where renewal conversations break down.
THE CHALLENGE
You sit down with the client to walk them through their parametric cover. The conversation goes the way it always does. The client follows your argument. They nod agreeably.
Two weeks later, the email comes. Polite. They've increased their traditional limit at renewal. They won't need a parametric layer this year.
Not a rejection. Another exit. The hit rate is brutal.
THE PROXY GAP
What the trigger measures ≠ what the location experienced
Every parametric hurricane trigger on the market measures a proxy: distance from the track, a sensor somewhere else, a reconstruction from stations that may not have survived. None of them measure what your client's location actually experienced. At Reask, we call it the proxy gap.
Cat-in-a-Circle
Measures whether the storm centre crosses a boundary — not what wind your location experienced. A direct hit can miss the trigger. A distant storm can fire it.
Cat-in-a-Shape
A polygon instead of a circle doesn't close the proxy gap. The trigger still measures storm geometry, not conditions at the insured location.
Simplified wind-field models
Mathematically a moving Cat-in-a-Circle with finer payout steps. Terrain doesn't exist. A hotel behind a hill gets the same number as one in front of it.
Physical anemometers
Sensors fail during extreme events — exactly when the measurement matters. The proxy gap isn't eliminated. It's relocated to a fragile instrument somewhere else.
Observation-based reconstruction
Inheriting every limitation of anemometers. Historical footprints are not based of today's station network. Back-testing payouts is inconsistent. Expert judgement enters where objectivity is needed most.
THE SOLUTION
Wind speed at the location.
Not a proxy.
Metryc is a parametric trigger based on modelled wind speed at the insured location. It starts with the same NHC, JTWC, JMA and BOM track data the rest of the market uses. From there, it samples uncertain wind-field parameters, runs 100 physically grounded simulations of every storm, applies a terrain correction at 1 km resolution, and returns the most probable wind speed at your specific location.
After the storm, everything changes.
For the broker. For the insured. For the renewal conversation.
