Fed's Williams warns low-rate mortgage lock-in will persist for years
In brief
- Nearly half of US mortgages carry rates below 4%, with 19.5% locked below 3% as of Q1 2026.
- Current mortgage rates at 6-7% create 300+ basis point gap, discouraging refinancing and home sales.
- Fed research shows 44% decline in homeowner mobility and 8% price gains in lock-in markets since 2022.
- Fed officials now view mortgage lock-in as structural feature, not temporary market quirk.
The Scale of the Lock-In
As of Q1 2026, roughly 19.5% of outstanding US mortgages carry rates below 3%. That's down from a peak of 24.6% in Q1 2021, but the decline has been painfully slow. Current mortgage rates hover between 6-7%, creating a 300+ basis point gap that leaves homeowners trapped. Selling means losing a 2.5% or 3% mortgage. Refinancing means locking in 6.5% or higher. Neither option appeals.
Williams and other Fed officials have indicated this is now a structural feature of the housing market, not a temporary glitch. The imbalance will persist for years, shaping both real estate dynamics and monetary policy.
Impact on Supply, Prices, and Mobility
Fed research estimates that the rate hikes beginning in 2022 drove a 44% decline in homeowner mobility. Fewer people move when they can't afford to leave their low rate. Fewer homes on the market means prices stay elevated. In fact, Fed research suggests home prices have risen by approximately 8% in markets most affected by this dynamic.
The supply crunch has become self-reinforcing. Tight inventory keeps prices high, which further discourages sales and locks in existing homeowners.
Fed's Portfolio Runoff
The Federal Reserve is also conducting a gradual runoff of its mortgage-backed securities portfolio, shedding roughly $15-20 billion per month. This reduces the Fed's balance-sheet support for the mortgage market but doesn't directly address the lock-in problem.
Williams' acknowledgment that resolution will take years signals the Fed expects elevated housing costs and constrained supply to remain a headwind on consumer spending and inflation dynamics for the foreseeable future.
"Williams stated that many Americans still hold low-rate mortgages secured during the pandemic-era borrowing bonanza, and that resolving this structural imbalance will take years." — New York Fed President John C. Williams
Frequently asked questions
Why won't homeowners with low mortgage rates sell or refinance?
Current mortgage rates are 6-7%, compared to the 2.5-3.5% rates many homeowners locked in during the pandemic. Selling means losing that low rate; refinancing means accepting a much higher rate. Neither is economical, so homeowners stay put.
How does the mortgage lock-in affect home prices?
Fewer homes on the market due to the lock-in effect means supply is tight. Fed research shows home prices have risen approximately 8% in markets most affected by this dynamic. The supply crunch keeps prices elevated.
Why is the lock-in effect a structural problem, not temporary?
Williams and other Fed officials now view the lock-in as a permanent feature of the housing market. The percentage of mortgages below 3% has only declined from 24.6% in Q1 2021 to 19.5% in Q1 2026 — a painfully slow pace. Resolution will take years.
