Climate Change Exacerbates Mortgage Risks, Imperiling Banking System

Strategic Insights -

A new report by First Street highlights the crucial link between climate-driven extreme weather events and mortgage defaults. The analysis, which marks the first national-scale evaluation of the relationship between physical climate risk and mortgage defaults, warns that foreclosure losses could reach $5.36 billion annually by 2035, threatening nearly 30% of all bank credit losses. The study reveals that flooding, a leading climate driver of foreclosure risk, often remains uninsured due to gaps in insurance coverage, posing a significant threat to the mortgage market.
