Federal Reserve’s Williams says low-rate mortgage lock-in will persist for years
Nearly half of all US mortgages still carry rates below 4%, creating a housing market gridlock that the New York Fed president says won't resolve anytime soon
New York Fed President John C. Williams has a message for anyone waiting for the US housing market to unclog: bring a chair, you’ll be here a while.
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. The comment underscores a growing consensus among Fed officials that one of the most stubborn side effects of aggressive rate hikes, the so-called “lock-in effect,” has essentially frozen a massive chunk of the housing market in place.
The numbers behind the gridlock
As of the first quarter of 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.
Nearly half of all US mortgages still sit below 4%. Meanwhile, current mortgage rates hover between 6-7%. Fed research estimates that the rate hikes beginning in 2022 drove a 44% decline in homeowner mobility.
That reduced mobility has a cascading effect. Fewer people selling means fewer homes on the market. Fewer homes on the market means prices stay elevated. Fed research suggests home prices have risen by approximately 8% in markets most affected by this dynamic.
Why the thaw has stalled
Recent observations suggest that momentum has stalled in early 2026. Williams and other Fed officials have indicated this is now a structural feature of the housing market, not a temporary glitch. The only reliable mechanism for unwinding it is time itself, as mortgages naturally mature and people’s lives change in ways that override financial optimization.
The Federal Reserve is also conducting a gradual runoff of its mortgage-backed securities portfolio, shedding roughly $15-20 billion per month. But this is a slow-motion process designed to avoid disrupting bond markets, not a tool for directly addressing housing supply constraints.
What this means for investors and crypto markets
First, it signals that the Fed is unlikely to slash rates aggressively anytime soon. If officials like Williams are describing the lock-in effect as a multi-year structural problem, they’re implicitly acknowledging that the current rate environment is here to stay for an extended period.
The 8% price appreciation in lock-in-affected markets represents a form of silent inflation that doesn’t always show up cleanly in the Fed’s preferred metrics. Housing costs remain one of the stickiest components of inflation readings. As long as supply stays constrained and prices stay elevated, the Fed has less room to justify significant easing.
Williams has essentially confirmed what market participants have suspected: this is a multi-year workout, not a quick fix.
