Fed Rate Cut in December: What It Could Mean for Mortgage Rates

Mortgage rates today are hovering near a 13-month low even as traders once again price in a strong chance of a December Federal Reserve rate cut, but history shows those two facts don't automatically move together. The average 30-year fixed rate sits at 6.43%, and whether it falls further after the Fed's Dec. 10 decision is far from guaranteed.

Markets Swing Back Toward a December Cut

As of this writing, fed funds futures assign roughly an 85% probability to a quarter point cut at the Fed's December meeting. That's a striking reversal from just a week earlier, when traders were split on a cut versus a hold, and from five days ago, when a pause looked like the consensus call.

Some of that whiplash traces back to a data vacuum left by the recent government shutdown, which delayed timely economic releases the Fed normally relies on. But the bigger driver is the tension policymakers are wrestling with: inflation remains above target, which would typically argue for holding rates steady, while labor market softness points toward easing.

The tipping point came Friday, when a senior Fed official signaled openness to a December cut. That single comment was enough to flip futures pricing from a likely hold to a likely cut almost overnight. It's a reminder that rate cut odds are as much a function of Fed communication and investor interpretation as they are of hard data, and they can shift again before the committee actually meets.

Why the Fed's Move Won't Dictate Mortgage Rates

The instinct to assume a Fed cut trickles straight into mortgage pricing is understandable, but it doesn't hold up well empirically. The Fed's benchmark rate primarily governs short-term borrowing costs, things like credit cards, auto loans and savings account yields. Mortgage rates answer to a different master: the bond market, particularly the 10-year Treasury yield.

That yield reflects investor expectations for growth, inflation and the Fed's future policy path, not just its next move. When investors anticipate resilient growth or worry inflation could reaccelerate, yields and mortgage rates can climb even as the Fed cuts.

The recent record backs this up. Mortgage rates rose, not fell, after the Fed's cuts in September and October. Go back further: the Fed slashed rates by a full percentage point between September and December 2024, yet the average 30-year mortgage rate was nearly 1.25 points higher by January than it had been before those cuts began. Anyone counting on a mechanical, one-to-one relationship between Fed action and mortgage pricing has been repeatedly disappointed.

Where Rates Actually Stand

Context matters here. The 6.43% average 30-year rate is above October's 6.35%, which was the lowest print in 13 months, but it's meaningfully below the 7.15% peak hit in mid-May. That puts current rates roughly 10% below their spring high, a real if modest improvement for affordability.

Weighing Whether to Lock Now or Wait for Lower Rates

Forecasters aren't projecting a dramatic drop. Fannie Mae and most other major forecasts see 30-year rates settling in the low 6% range by the end of 2025 and slipping just under 6% sometime late in 2026. That's a gradual grind lower, not a return to the sub-3% and sub-4% rates borrowers got used to a few years ago.
