Rising Nat Cat Costs Challenge Homeowners-Line Carriers — and May Weigh on Municipal Credit
September 15, 2025

The rising complexity and costs of catastrophes in the U.S. are challenging homeowners carriers, hampering profitability and driving up insurance premiums. In some high-risk regions, a weaker insurance market, in combination with economic and demographic impacts of catastrophes, may be a drag on a region or state’s credit quality.
As insurers come to terms with the new realities of today’s natural catastrophes, they are raising prices and — in worst cases — abandoning certain markets altogether, adding to the cost of living and limiting home-price appreciation1. These factors can influence where people choose to live, possibly steering them away from the more exposed regions.
The impact on a region’s housing market and economic activity can be a significant factor in determining municipal credit quality, as seen in Louisiana. Texas offers an example of how a state facing a regular slate of challenging weather events can still have a vibrant economy and draw new residents.
