Federal flood insurance loses its authority on December 11 and nearly 4.5 million policies ride on it

Section 139 of a stopgap spending law moved the expiration of the National Flood Insurance Program’s authority from September 30 to December 11, 2026, which leaves a little over two months before Congress has to act again. The Congressional Research Service says the program insures nearly 4.5 million policies, a count it takes from FEMA data. Those policies do not vanish on the deadline, but the program’s power to sell new coverage and renew expiring policies does stop, and that matters most to anyone buying a home or renewing a policy in a flood zone.

What section 139 of Public Law 119-103 actually changed

The text is on GovInfo. H.R. 6500, the Continuing Appropriations and Extensions Act, 2027, became Public Law 119-103 when it was enacted on September 2, 2026. Section 139(a) directs that sections 1309(a) and 1319 of the National Flood Insurance Act of 1968, codified at 42 U.S.C. 4016(a) and 4026, “shall be applied by substituting the date specified in section 106(3) of this Act for ‘September 30, 2026.’” Section 106(3) of the same law names December 11, 2026.

The mechanism is an edit to the program’s expiration dates, not a new appropriation for flood insurance. Section 139(b) makes the change effective on enactment and adds that, if the law had been enacted after September 30, it would be applied as though it had been in effect on that date. Because the law was signed on September 2, that backstop never came into play, and the program went into October with its authority intact.

The 4.5 million figure belongs to CRS, citing FEMA

The policy count comes from a Congressional Research Service report titled “What Happens If the National Flood Insurance Program (NFIP) Lapses?”, dated September 11, 2026. The sentence reads that the NFIP has “nearly 4.5 million flood insurance policies,” and the footnote points to FEMA’s flood insurance data page. The report does not date the count, so it is best read as the approximate size of the book of business rather than a figure measured on a particular day.

The phrase “nearly 4.5 million” is the source’s own wording, and it is a count of policies, not of homes or people.

Existing policies keep paying through their terms

A lapse in authority is not a cancellation notice. CRS states that existing policies continue through their one-year terms, and the National Association of Realtors, in its FAQ on the December 11 expiration, says that “Existing NFIP policies remain in effect until their expiration date, including a 30-day grace period.” Claims keep moving too: CRS writes that FEMA “would continue to adjust and pay claims as premium dollars come into the National Flood Insurance Fund and reserve fund,” and NAR says claims “will continue to be paid as long as FEMA has funds.”

What stops is issuance. NAR’s FAQ says new and renewal policies cannot be issued during a lapse. A policy that comes due for renewal in that window therefore has no NFIP renewal to buy until Congress restores authority, which is why the calendar position of each policy matters more than the headline number. NAR adds that private flood insurance is unaffected by a lapse, and that an insurer can assign a seller’s NFIP policy to a buyer by substituting names, so coverage on the property stays in place.

Why home closings are the pressure point

The mandatory purchase requirement, which ties flood coverage to federally backed mortgages in high-risk zones, is enforced by lenders rather than by FEMA. CRS recalls that during a 2010 lapse “over 1,400 home sale closings were canceled or delayed each day.” That is a historical figure from one episode, not a forecast for December.

Lenders’ behavior has varied since. CRS notes that during the October to November 2025 government shutdown, some lenders suspended the flood insurance requirement. NAR describes the regulators’ side of the same dynamic: “Most federal lending regulators suspend the flood insurance purchase requirement during a lapse, leaving it up to lenders to decide whether to make loans in special flood hazard areas.” The decision for a given closing, in other words, belongs to the lender, and NAR’s description is its own reading of regulator practice, not a rule that the requirement is cancelled.

Borrowing authority drops from $30.425 billion to $1 billion

The lapse also changes the program’s finances. CRS writes that “the authority for NFIP to borrow funds from the Treasury will be reduced from $30.425 billion to $1 billion.” That cut is a statutory consequence of the same expiration, and it bears on how much a heavy claims year could be absorbed without new action from Congress. The report does not forecast a specific storm season or a specific claims total.

The reduction in borrowing authority does not itself stop claims from being paid. CRS ties continued payment to premium dollars flowing into the program’s funds, the same sentence quoted above, and NAR’s version ties it to FEMA having funds. Both descriptions leave the question of a very large claims year open and attribute no figure to it.

Thirty-six short extensions and counting

The December 11 date is the latest of many. CRS counts 36 short-term reauthorizations since the end of fiscal year 2017, with lapses along the way, including during the October to November 2025 shutdown. Most lapses were repaired retroactively, but the gaps affected sales and renewals while they lasted.

A short date is the pattern the program has run on for nearly a decade. Congress can again move the expiration in another stopgap before December 11, let it pass, or pass a longer reauthorization; the statute as enacted sets only the date. The primary documents to watch are the GovInfo text of any later law and the CRS report, which carries the lapse mechanics in full.


Flood coverage is one line in a home’s yearly carrying costs

The December 11 date and the policy count are about one cost of owning a home, and that cost sits next to property taxes, utilities and repairs that arrive on their own calendars. Homeowners and renters who track those bills together are better placed when one of them shifts.
