The Federal Reserve’s long-awaited 25-basis-point rate cut on September 17, 2025, was supposed to usher in cheaper home loans, but mortgage rates climbed anyway, leaving buyers scratching their heads. With mortgage rates rise Fed cut, Fed rate cut mortgage impact, 30-year mortgage rates 2025, housing market Fed decision, and refinancing after rate cut surging in searches, this counterintuitive twist underscores how bond markets, not just Fed actions, dictate borrowing costs.
The Fed’s Move: A Modest Cut Amid Cautious Optimism
The Fed trimmed its benchmark federal funds rate to 4.25%-4.50%, the first reduction of 2025 after holding steady through January to July. Officials signaled two more cuts this year and one in 2026, citing a softening labor market and elevated uncertainty despite sticky inflation.
This 0.25% trim followed three cuts in late 2024 (September, November, December), totaling 1% easing. Yet, markets had already baked in the move, with 30-year fixed rates dipping to 6.35% pre-announcement.
The Immediate Backfire: Rates Climb Despite the Cut
Post-announcement, the average 30-year fixed mortgage rate rose to 6.20% by September 18, up from 6.13% the prior day. This echoes patterns from December 2024 and September 2024, where cuts preceded upticks.
The culprit? A hotter-than-expected jobs report on September 19, showing robust growth and steady 4.1% unemployment. This signaled economic strength, prompting investors to demand higher yields on 10-year Treasuries—the key mortgage benchmark—pushing it up and dragging rates higher.
August inflation ticked to 2.9% from 2.7%, adding fuel to the fire. As one Reddit user noted, “Long-term rates are market-driven; Fed cuts don’t always override inflation fears.”
Background: Why Mortgage Rates Defy Fed Logic
Unlike short-term Fed funds, 30-year mortgages track the 10-year Treasury yield, influenced by investor bets on growth, inflation, and policy. Yields fell mid-July on weak jobs data, dropping rates to 6.35% by September 11.
But post-cut, positive data reversed course. In 2024, after three Fed easings, rates climbed from 6.09% to 6.91% by early 2025 due to election outcomes and tariffs stoking inflation. Secondary spreads—risk premiums on mortgage-backed securities—widened to 1.73%, amplifying hikes.
