This Insight provides a short overview of what would happen if the National Flood Insurance Program (NFIP) were not to be reauthorized by May 31, 2019, and allowed to lapse. See CRS Report R45099, National Flood Insurance Program: Selected Issues and Legislation in the 115th Congress for the current status of NFIP reauthorization legislation.

Expiration of Certain NFIP Authorities

The National Flood Insurance Program (NFIP) is authorized by the National Flood Insurance Act of 1968 (Title XIII of P.L. 90-448, as amended, 42 U.S.C. §§4001 et seq.). The NFIP does not contain a single comprehensive expiration, termination, or sunset provision for the whole of the program. Rather, the NFIP has multiple different legal provisions that tie to the expiration of key components of the program.

Since the end of FY2017, 12 short-term NFIP reauthorizations have been enacted. The NFIP is currently authorized until September 30, 2019. Authorization of the NFIP was extended from September 30 until December 8, 2017 (P.L. 115-56), extended until December 22, 2017 (P.L. 115-90), and again until January 19, 2018 (P.L. 115-96). The NFIP lapsed between January 20 and January 22, 2018, and received a fourth short-term reauthorization until February 8, 2018 (P.L. 115-120). This legislation also authorized FEMA to honor all policy-related transactions accepted during the NFIP lapse. The NFIP lapsed again for approximately eight hours during a brief government shutdown in the early morning of February 9, 2018, and was then reauthorized until March 23, 2018 (P.L. 115-123). The NFIP received a sixth reauthorization until July 31, 2018 (P.L. 115-141), a seventh until November 30, 2018 (P.L. 115-225), an eighth until December 7, 2018 (P.L. 115-281), a ninth until December 21, 2018 (P.L. 115-298), a tenth until May 31, 2019 (P.L. 115-396), an eleventh until June 14, 2019 (P.L. 116-19), and a twelfth reauthorization until September 30, 2019 (P.L. 116-20).

The cancellation of $16 billion of NFIP debt (P.L. 115-72) has no effect on the impact of a lapse of NFIP authorization. Unless reauthorized or amended by Congress, the following will occur on September 30, 2019:

Other activities of the program would technically remain authorized, such as the issuance of Flood Mitigation Assistance Grants. However, the expiration of the key authorities listed above would have potentially significant impacts on the remaining NFIP activities.

The NFIP is the primary source of flood insurance coverage for residential properties in the United States. The NFIP has nearly 5.1 million flood insurance policies providing over $1.3 trillion in coverage, with over 22,000 communities in 56 states and jurisdictions participating. The program collects about $3.6 billion in annual premium revenue.

If there were to be a lapse in authorization on or after September 30, 2019, and the borrowing authority is reduced to $1 billion, FEMA would continue to adjust and pay claims as premium dollars come into the National Flood Insurance Fund (NFIF) and reserve fund. If the funds available to pay claims were to be depleted, claims would have to wait until sufficient premiums were received to pay them unless Congress were to appropriate supplemental funds to the NFIP to pay claims or increase the borrowing limit.

The Mandatory Purchase Requirement

The expiration of the NFIP's authority to provide new flood insurance contracts has potentially significant implications due to the mandatory purchase requirement. By law or regulation, federal agencies, federally regulated lending institutions, and government-sponsored enterprises must require certain property owners to purchase flood insurance as a condition of any mortgage that these entities make, guarantee, or purchase. Property owners, both residential and commercial, are required to purchase flood insurance if their property is identified as being in a Special Flood Hazard Area (SFHA, which is equivalent to having an estimated 1% or greater risk of flooding every year) and is in a community that participates in the NFIP. Without available flood insurance, real estate transactions in an SFHA potentially would be significantly hampered.

In the Biggert-Waters Flood Insurance Reform Act of 2012 (Title II of P.L. 112-141), Congress explicitly allowed federal agencies to accept private flood insurance to fulfill this mortgage requirement if the private flood insurance met the conditions defined in statute. The private flood insurance market, however, has been slow to develop and the mandatory purchase requirement is still generally met through NFIP coverage.

Past Lapses of the NFIP

The NFIP was extended 17 times between 2008 and 2012, and lapsed four times: March 1 to March 2, 2010; March 29 to April 15, 2010; June 1 to July 2, 2010; and October 1 to October 5, 2011. In most cases when the NFIP lapsed, Congress reauthorized the NFIP retroactively. During these NFIP lapses, the FDIC issued guidance to lending institutions, and the Federal Reserve also issued informal guidance to lenders. FEMA provided guidance for the Write-Your-Own (WYO) Program, where private insurance companies are paid to write and service NFIP policies.

In past NFIP lapses, borrowers were not able to obtain flood insurance to close, renew, or increase loans secured by property in an SFHA until the NFIP was reauthorized. During the lapse in June 2010, estimates suggest that over 1,400 home sale closings were cancelled or delayed each day, representing over 40,000 sales per month. These figures applied to residential properties, but commercial properties were also affected by the NFIP lapse. In addition, the largest WYO insurer left the NFIP in 2011 reportedly because of the administrative burden associated with very short-term reauthorizations and lapses in authorization. Although no detailed analysis of the NFIP lapses in 2010 and 2011 has been undertaken, the economic impact could potentially have been broader than the reported effects on the domestic real estate market.
