What Happens If the National Flood 
Insurance Program (NFIP) Lapses?  
Updated October 4, 2021 
This Insight provides a short overview of what would happen if the National Flood Insurance Program 
(NFIP) were not to be reauthorized by December 3, 2021, and al owed to lapse. 
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, 17 short-term NFIP reauthorizations have been enacted. The NFIP is currently 
authorized until  December 3, 2021. 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 al  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 6th reauthorization 
until July 31, 2018 (P.L. 115-141), a 7th until November 30, 2018 (P.L. 115-225), an 8th until December 7, 
2018 (P.L. 115-281), a 9th until December 21, 2018 (P.L. 115-298), a 10th until May 31, 2019 (P.L. 115-
396), an 11th until June 14, 2019 (P.L. 116-19), a 12th until September 30, 2019 (P.L. 116-20), a 13th until 
November 21, 2019 (P.L. 116-59), a 14th until December 20, 2019 (P.L. 116-69), a 15th until September 
30, 2020 (P.L. 116-94), a 16th reauthorization until September 30, 2021 (P.L. 116-159), and a 17th 
reauthorization until December 3,2021 (P.L. 117-43).   
The cancel ation of $16 bil ion  of NFIP debt (P.L. 115-72) had no effect on the impact of a lapse of NFIP 
authorization. Unless reauthorized or amended by Congress, the following wil  occur on December 30, 
2021:

  The authority to provide new flood insurance contracts wil  expire. Flood insurance 
contracts entered into before the expiration would continue until the end of their policy 
term of one year.  
  The authority for NFIP to borrow funds from the Treasury wil  be reduced from $30.425 
bil ion  to $1 bil ion.  
Other activities of the program would technical y remain authorized, such as the issuance of Flood 
Mitigation Assistance Grants. However, the expiration of the key authorities listed above would have 
potential y 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 more than 5 mil ion  flood insurance policies providing over $1.3 tril ion  in coverage, with 
22,522 communities in 56 states and jurisdictions participating. The program collects about $4 bil ion in 
annual premium revenue and fees. 
If there were to be a lapse in authorization on or after September 30, 2021, and the borrowing authority is 
reduced to $1 bil ion, 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 potential y significant 
implications due to the mandatory purchase requirement (MPR). By law or regulation, federal agencies, 
federal y 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 potential y 
would be significantly hampered.  
In the Biggert-Waters Flood Insurance Reform Act of 2012 (Title II of P.L. 112-141), Congress explicitly 
al owed federal agencies to accept private flood insurance to fulfil  the MPR if the private flood insurance 
met the conditions defined in statute. Although the private flood insurance market is growing, the MPR is 
stil  general y met through NFIP coverage. FEMA does not enforce the MPR, but lenders must continue 
their regulatory requirements during a lapse, including MPR enforcement. 
Past Lapses of the NFIP 
The NFIP was extended 17 times between 2008 and 2012, and lapsed 4 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 over 1,400 home sale closings were cancel ed 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 have been broader than the reported effects on the domestic real estate market.
