What are today's mortgage interest rates: December 12, 2025?

Following the Fed’s final 2025 meeting and its year-end rate cut, mortgage rates have continued a gradual decline: Zillow reports average 30‑year purchase rates at 5.99% and 15‑year at 5.37% as of Dec. 12, 2025, while average refinance rates sit at 6.77% for 30‑year (up from 6.67%) and 5.67% for 15‑year. Lenders and borrowers should note that despite the Fed cut and Chairman Powell’s guidance on 2026 policy, mortgage yields can move independently (they have ticked up after prior cuts), and refinancing economics still hinge on closing costs and break‑even timing. The current levels—near historical averages and materially below early‑2025 peaks—could prompt incremental purchase and refinance activity if borrowers can secure sub‑6% deals after shopping lenders.

Analysis

The Federal Reserve completed its final 2025 meeting and issued a year-end rate cut, leaving the federal funds rate at its lowest level since 2022; mortgage markets have reacted with gradual declines through 2025 but remain sensitive to Fed guidance. Zillow reports average purchase mortgage rates on Dec. 12, 2025 at 5.99% for a 30-year and 5.37% for a 15-year, while average refinance rates are 6.77% for a 30-year (up from 6.67%) and 5.67% for a 15-year. These levels put purchase rates near long-term historical averages and materially below early-2025 peaks, which could support incremental purchase demand and rate-shopping activity. Refinance economics remain constrained by closing costs and break-even timing; prior post-cut behavior—where mortgage rates ticked higher after earlier Fed cuts—highlights the risk that mortgage yields can move independently of the federal funds rate, so market participants should watch MBS spreads, Powell's 2026 guidance, and consumer lock-in dynamics closely.

Key Decisions for Investors

• Homeowners should calculate refinance break-even including closing costs and avoid refinancing if they plan to sell before recovering those costs,
• Mortgage borrowers looking to purchase should shop aggressively and consider locking if they can secure a sub-6% 30-year or sub-5.5% 15-year rate, given current averages and the potential for incremental improvement,
• Fixed-income and MBS investors should monitor Fed forward guidance, MBS spread behavior and post-cut yield dynamics and consider hedging duration exposure until a clear downtrend in mortgage yields is confirmed,
• Equity investors in housing services and rate-shopping platforms (e.g., Zillow-related exposure) may consider a modest tactical overweight to capture increased traffic, while watching refinance volume and consumer sentiment which are only mildly positive
