Mortgage and refinance interest rates today for December 8, 2025: Will rates go down after the Fed meeting?

Mortgage rates ticked higher last week despite expectations of another Federal Reserve cut, with Zillow reporting the 30-year fixed at 6.10% (up 13 bps), the 15-year at 5.55% (up 14 bps) and a 5/1 ARM at 6.45%; refinance averages are similarly elevated. The Fed’s forthcoming decision could influence direction, but past cuts have not reliably pushed mortgage rates lower — they would likely fall only if the Fed signals materially more aggressive easing next year — a dynamic that matters for housing demand, refinance activity and MBS valuations. Absent clearer Fed easing or lower inflation, economists cited in the piece don’t expect significant rate declines before year-end, so investors should watch Fed guidance and mortgage spread behavior for housing-sector and mortgage-backed security risks/opportunities.

Analysis

Zillow's latest national averages show the 30-year fixed mortgage rate at 6.10% (up 13 basis points week-over-week) and the 15-year fixed at 5.55% (up 14 basis points); ARMs remain elevated with a 5/1 ARM at 6.45% and the national 30-year refinance average at 6.15%. These figures are rounded national averages and indicate borrowing costs ticked higher despite expectations of Fed easing.

The Federal Reserve's upcoming decision on a potential third cut this year is the immediate catalyst; many experts predict another cut, but the article emphasizes that past Fed rate cuts have not reliably translated into lower mortgage rates. Mortgage rates are likely to decline only if the Fed signals materially more aggressive easing next year, and economists cited do not expect significant rate drops before year-end.

Sustained elevated mortgage rates imply weaker housing demand and lower refinance activity, pressuring MBS valuations and mortgage-originator pipelines. Investors should therefore monitor Fed forward guidance, mortgage spread behavior versus Treasuries, inflation signals and regional housing differentials as the primary drivers of near-term performance in housing-related assets.

Key Decisions for Investors

• Reassess duration exposure in mortgage-backed securities and consider interest-rate hedges given a 30-year average at 6.10% and limited near-term downside
• Delay new long-duration housing or homebuilder positions until the Fed provides clearer forward guidance or mortgage spreads compress materially
• Monitor mortgage spread versus Treasury moves and Fed language closely as the decisive trigger for mortgage-rate relief and set alerts for materially more aggressive easing signals
• For lenders and originators, selectively lock pipelines and stress-test credit and prepayment assumptions under a higher-for-longer mortgage-rate scenario
