Frost parametric insurance

Frost parametric insurance pays when temperatures drop below an agreed threshold during a sensitive period, protecting crops and operations that a cold snap can ruin overnight.

Frost is a timing dependent risk that can wipe out a year of work in a single night, and it is hard to assess and slow to settle under conventional cover. Parametric pays the moment the cold crosses the agreed line.

This page explains what frost costs a business, why traditional cover falls short, how Trigger structures frost parametric cover, the trigger and data behind it, how basis risk is managed, an example structure, the businesses it suits, and how fast it pays.

What frost costs a business

A single frost at the wrong moment can destroy a fruit or vine crop, damage sensitive produce and disrupt operations, wiping out a year of work in a night. For orchards and vineyards, a late spring frost during budding is one of the most feared events of the year. Because the loss is so timing dependent, and because a damaged crop is hard to value precisely, the financial impact is severe and the recovery long.

Where traditional cover falls short

Valuing a lost harvest after a frost is slow and contentious, and named peril crop cover can be narrow, excluding the specific conditions or timing that caused the loss. The delay in settlement is especially damaging when a grower needs funds quickly to manage the aftermath and prepare for the next season. A minimum temperature trigger pays the moment the cold crosses the agreed line, with no need to assess the crop.

How Trigger structures frost cover

Cover is built on a minimum temperature trigger at your location during the sensitive window, paying when temperatures fall below the agreed level. Payouts scale with how far and how long temperatures breach the threshold, so a deeper or longer frost releases a larger payout up to the agreed maximum. The window, threshold and scale are fixed in advance, and the payout follows the published temperature data.

The trigger and the data behind it

The trigger uses independent temperature data. Minimum temperature is precisely and reliably measured by meteorological stations and reanalysis data, which makes the trigger robust and easy to verify. A trigger is typically defined as the temperature falling below a set level at the site during a defined budding or growing window. The accuracy and long history of temperature data make frost a clean peril to structure. Read more on the data used in parametric insurance.

Reducing basis risk on frost cover

Basis risk on frost cover comes from the distance between the measurement station and your land, and from local variation in temperature, such as frost pockets. It is reduced by using data as close to the site as possible, choosing the threshold that matches the point of crop damage, and calibrating the window to your crop's sensitive period. Every trigger is back tested against past seasons so the fit is clear before cover is bought. Read more on how basis risk is managed.

Who should consider frost cover

Frost cover is most valuable to growers of high value, frost sensitive crops, where a single cold night at the wrong moment can destroy a year of production. Orchards, vineyards and horticultural producers are the clearest examples, because their crops are especially vulnerable during budding and flowering, and the loss from a late frost can be catastrophic and impossible to recover in the same season. Agricultural lenders financing these producers also benefit, because frost cover protects the revenue that services seasonal debt. Because frost is so timing dependent, the design of the sensitive window and the temperature threshold is central to a well fitting structure, and we calibrate both against each grower's crop and location. For any producer whose livelihood can turn on a single cold snap, a defined minimum temperature trigger turns one of farming's most feared risks into fast, certain protection.

Example structure

A vineyard takes cover that pays when temperatures fall below a set level during the budding window, with a larger payout for a deeper or longer frost. When the temperature data confirms a qualifying frost, the payout is settled within days, funding recovery and the cost of the lost vintage.

Which businesses and sectors it suits

Frost parametric cover suits agriculture, orchards and vineyards, food production, and horticulture. Agricultural lenders use it to protect the revenue that services seasonal debt. It is valuable to any grower whose crop can be destroyed by a cold snap at the wrong moment.

How fast the cover pays

Because there is no loss to assess, a frost parametric policy pays within days of the temperature data confirming the trigger. Timing depends on the publication of the official reading rather than a survey of the crop, so funds arrive soon after the frost, when the grower is managing the aftermath. Frost sits within our weather parametric insurance line, and is often structured alongside drought and heatwave cover for the same season.
