The National Flood Insurance Program (NFIP) insures 5.6 million American homeowners and some $1 trillion in assets. For many years, however, the premiums collected have not been sufficient to cover losses, resulting in a current debt to the U.S. Treasury of more than $18 billion. A number of factors, including increased flooding as a result of climate change, are likely to further widen the gap between revenue and risk. Reforms are needed to put the NFIP on the path to solvency and to reduce homeowners’ exposure to chronic and catastrophic flooding risk. Ideally, such reforms should fully account for the increased risks posed by climate change. At a minimum, steps are needed to adjust premiums, improve flood mitigation measures, and prepare for the catastrophic risk of events like Hurricane Katrina.
With government budgets still reeling from the effects of the recent recession, and ongoing debates over the future costs of Medicare and Social Security, unfunded public liabilities are of growing concern. The National Flood Insurance Program (NFIP) is one such liability that is often overlooked. The NFIP is already significantly in debt due to premiums that have not reflected the true risk of flood damages. Looking forward, the risk of further losses only increases, as demographic trends place more infrastructure in harm’s way, watersheds are developed and climate change increases flood risk over time.
This paper explores the structural issues underlying the growing gap between flood insurance premiums and actual flood risk. It also examines reforms that can put the program on a more sound financial footing and the incentives needed to reduce the potential costs of future flooding. A report by the American Enterprise Institute found that insurers have “a huge opportunity today to develop creative loss-prevention solutions.”  Using both adaptive and financial tools to manage the rising risks posed by climate change will be critical to preventing losses and maintaining the insurability (and therefore property values) of trillions of dollars in at-risk property assets.
Between 1980 and 2005, U.S. insurers paid out a total of $320 billion in weather-related insurance claims. While not all weather-related claims are flood claims, losses from weather events are increasing. Today, the NFIP covers over $1.2 trillion in assets, representing more than a fourfold increase since 1980. If providing this coverage is to remain affordable, Congress must provide FEMA with the tools to accurately price and manage risk.
