Flood parametric insurance

Flood parametric insurance pays when a measured flood level or extent crosses an agreed threshold, settling quickly when conventional flood claims are slow, restricted or excluded altogether.

Flood is one of the most frequently sub limited or excluded perils in standard cover, which leaves many businesses badly exposed to a risk that is growing. Parametric closes that gap by paying on independent flood data rather than a surveyed loss.

This page explains what flooding costs a business, why traditional cover falls short, how Trigger structures flood 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 flooding costs a business

Flooding damages stock, premises and equipment, and cuts the roads, ports and supply routes a business depends on, so the loss extends well beyond the water damage itself. Recovery costs climb with every day of disruption, and contaminated or ruined goods often cannot be recovered at all. Because flood affects whole areas at once, it hits many businesses and many borrowers together, and it is one of the perils where the gap between economic loss and insured loss is widest. Where flood is offered at all in standard cover, it often comes with tight limits, high deductibles, exclusions and slow settlement, because assessing flood damage across a large area is time consuming. Many businesses find that their most serious flood exposure is precisely the part their policy carves out. Parametric pays on the measured flood rather than a surveyed loss, so funds arrive when they are most useful and cover the exposure the standard market restricts.

Where traditional cover falls short

Conventional policies for this peril are often slow to pay, restricted or heavily excluded, and they settle only after the loss has been assessed. Parametric removes that delay by paying on the event itself. Compare the two in parametric vs traditional insurance.

How Trigger structures flooding cover

Triggers can be built on river gauge levels, rainfall accumulation over a catchment, or satellite confirmed flood extent at your location. You set the limit and the payout scale, and the agreed amount is paid when the measured value crosses the threshold, free to use across recovery and operating costs. Scaled structures pay more as the flood worsens, up to an agreed maximum. Because the trigger relies on published data, there is no adjusting and settlement follows within days.

The trigger and the data behind it

The trigger uses independent flood data. River gauges provide continuous level readings, rainfall records capture the driving conditions, and earth observation satellites map flood extent, including in regions with limited ground infrastructure. A trigger might be defined as a gauge exceeding a set level, a rainfall total over a catchment, or a mapped flood extent reaching the insured location. Combining sources can strengthen the trigger where a single measure would not track the exposure closely enough. Read more on satellite data in insurance and the data used in parametric insurance.

Reducing basis risk on flooding cover

Basis risk on flood cover comes from the relationship between the measured level or extent and the flooding actually experienced at your site, which depends on local topography and defences. It is reduced by choosing the gauge or satellite product closest to your exposure, blending sources where helpful, and calibrating the threshold against local flood history. Every trigger is back tested against past floods so the fit is clear before cover is bought. See how basis risk is managed.

Why flood risk is rising

Flood is becoming more frequent and more severe as heavier rainfall, rising sea levels and expanding development put more assets in harm's way. Areas once considered low risk now flood, and existing defences are increasingly overtopped, which widens the gap between the flooding businesses expect and the flooding they experience. As that gap grows, conventional flood cover is coming under pressure, with tighter limits and higher prices in the most exposed areas. Parametric offers a way to keep meaningful, fast paying flood protection in place even where the traditional market is retreating, because it prices and pays on measured flood data rather than on a shrinking appetite for the risk. For any business in or near a floodplain, or dependent on routes that flood, the case for a defined, independent flood trigger is strengthening year on year.

Example structure

A logistics operator takes cover that pays when a nearby river gauge exceeds a defined level, releasing funds to reroute freight, hire temporary capacity and cover the cost of idle assets. When the gauge reading is confirmed, the payout is settled within days, long before a conventional flood claim across the affected region would be resolved.

Which businesses and sectors it suits

Flood parametric cover suits agriculture and food production, construction and real estate, supply chain and logistics operators, and public sector bodies and infrastructure owners. Lenders use it to protect property and agricultural loan books in flood exposed areas. It is valuable to any business whose premises, stock or supply routes would be disrupted by a flood the standard market will not fully cover.

How fast the cover pays

Because there is no loss to assess, a flood parametric policy pays within days of the flood data being confirmed. River gauge readings are available continuously and satellite flood maps are produced quickly after an event, so the timing depends on confirming the official data rather than surveying the damage. Funds therefore arrive in the crucial early days, when a business is deciding how to keep operating. Flood is written as part of our catastrophe parametric insurance line, so it can be combined with the other catastrophe perils in one programme.
