A new report from Willis Towers Watson Plc warns that flood-related economic losses in Southeast Asia could increase up to tenfold in the coming years. The study highlights that the region’s vulnerability to extreme weather events is expected to rise significantly, with major flooding incidents now projected to cause losses exceeding $10 billion.
Historically, regional flooding events have resulted in economic damages ranging from $1 to $2 billion annually. However, as climate change intensifies, the frequency and severity of such events are expected to escalate, posing a greater financial threat to the region’s economies.
The report, titled Natural Catastrophe Review 2026, underlines the urgent need for enhanced preparedness and better risk management strategies to cope with the escalating flood risks in Southeast Asia. As extreme weather continues to disrupt communities and industries, the financial consequences could become even more devastating in the years ahead.
