Our downloadable playbook will help you master the technical frameworks, data strategies and portfolio insights to transform flood-risk volatility into a competitive edge.
About this playbook
The global insurance market is evolving. Through 2026 and beyond, it is expected to move from a period of strong profitability and sharp rate increases into a softer phase characterised by heightened competition and more moderate pricing growth. At the same time, climate change is intensifying flood risk, while loss costs continue to rise due to economic and social inflation.
How do flood underwriters remain both competitive and profitable in this changing market? What tools, solutions and strategies are there to help you turn climate risk into opportunity? We’ve created a downloadable underwriting resource that will help you navigate the new insurance landscape, exploring how an evolving climate is affecting both flood risk and the way underwriters manage it.

Calculating flood risk in a changing climate
Climate change is increasing the frequency and severity of flood events on a significant and global scale. Floods now account for up to 40% of extreme weather-related disasters, and the number of people exposed to flood risk increased by almost 25% between 2000 and 2020.
According to Swiss Re, global insured losses from natural catastrophes reached $107 billion in 2025, with flooding a primary driver of those losses. This underlines the urgent need for better risk modeling and adaptation strategies.
The big three challenges for underwriters – and their solutions
Standing out from the crowd
Traditional risk assessment doesn’t have the granularity needed to balance profitability with competitive pricing.
Drowning in data
Processing numerous and increasingly large and complex datasets takes time – and timelines are getting shorter.
The uncertainty gap
There’s no way to avoid uncertainty in flood risk, which makes it difficult to estimate the probability and financial impact of future events.
Reliable, validated, high-resolution flood hazard data.
Agile tools such as Risk Scores that translate complex variables into a single, actionable metric.
A glass-box approach to building flood models means you can gauge and quantify uncertainty.

Our practical guide explores the challenges that underwriters are facing in a non-stationary climate, and lays out some of the tools, strategies and solutions that will help to not just survive but to thrive.
Quote When managed properly, as laid out in this guide, rising climate risk presents a valuable opportunity for proactive flood risk underwriters. Rather than posing a threat to profitability, it offers insurers a unique chance to improve and expand their margins, build resilience, and diversify in today’
