Flood risk analytics for infrastructure debt

The flood exposure of any asset, priced in basis points.

FloodGate screens 42,037 ports, airports and power plants against 689 global flood hazard layers — and translates the hazard into expected damage and probability of default, with peer-reviewed methodology and open data.

How it works

From coordinates to basis points in three steps.

01

Find the asset

Pick a country and asset type, then select from every port, commercial airport and power plant we track there.

02

Set the scenario

Historical baseline or RCP 4.5 / RCP 8.5 out to 2080 — with full control over climate models, coastal settings and damage functions.

03

Read the risk

Flood depth by return period, expected damage as a share of asset value, and the uplift to probability of default in basis points.
