What are today's mortgage interest rates: January 15, 2026?

As of January 15, 2026 Zillow reports average mortgage rates at 5.87% for a 30-year fixed and 5.25% for a 15-year fixed; median refinance rates are 6.62% (30-year) and 5.53% (15-year). Rates have fallen from above 7% in early 2025, creating refinancing and purchase opportunities, though upcoming unemployment and inflation releases plus the first Fed meeting of 2026 could drive further movement and make timing a risk for borrowers.

Analysis

Market structure: Falling 30-year mortgage averages (5.87% purchase, 6.62% median refi as of 1/15/26; 15-year 5.25%/5.53%) benefits homebuyers, homebuilders (ITB constituents: DHI, PHM, LEN) and mortgage originators via higher purchase/refi volume, while compressing margins for mortgage brokers and amplifying prepayment risk for mortgage REITs (AGNC, NLY). Pricing power will shift to lenders with lowest cost of funds and best tech to capture volume; large national banks and online originators (RKT) can scale, regional banks face NIM pressure if deposit costs lag.

Risk assessment: Near-term (days–weeks) volatility centers on CPI and the Fed meeting; a single CPI print >0.4% m/m or hawkish Fed communication could re-price 10yr yields +50–75bp and push 30yr mortgage >6.5%, reversing opportunistic trades. Tail risks include a rapid spike in unemployment >6% or regulatory limits on nonbank mortgage capital that would freeze credit and widen spreads; medium term (3–12 months) prepayment acceleration can erode MBS yields and equity cushions.

Trade implications: Tactical opportunities include long home-construction (ITB, DHI) and long agency MBS (MBB) duration plays hedged with short Treasury futures to capture spread compression if rates fall further (target expansion if 30yr <5.5% within 3 months). Short/hedge mortgage REITs (NLY, AGNC) via put spreads to protect vs prepayment-driven NAV compression; consider small long position in RKT for originator share gains if purchase volumes rise.

Contrarian angles: Consensus assumes steady declines; it underestimates that median refi rates (6.62% 30yr) still deter many borrowers — refi wave may be smaller than priced, limiting mortgage lender EPS upside. Also underappreciated is bank NIM lag: lower headline rates can still compress bank earnings for 2–4 quarters. Historical parallel: 2019 MBS rally was followed by fast prepayment pain for REITs; expect similar asymmetric outcomes this cycle.

Key Decisions for Investors

• Establish a 2.5% notional long in ITB (iShares U.S. Home Construction ETF) and add 1% each to DHI and LEN names if 30-year mortgage rate drops below 5.5% within 90 days; set stop-loss to trim full position if 10yr Treasury yield rises above 4.25% or CPI month >0.4%.
• Initiate a 3% notional long in MBB (iShares MBS ETF) hedged duration-neutral by shorting 10-year Treasury futures (match DV01) to capture MBS-Treasury spread compression; unwind if MBS spread over Treasuries widens >25bp from entry within 60 days.
• Put on a short position in mortgage REITs: buy 3-month NLY 5–7% OTM put spread sized to 2% portfolio risk (define max loss = premium) to protect against NAV/prepayment downside; widen to AGNC if volatility compresses premium.
• Allocate 2% to long RKT (Rocket Companies) as a directional originator play if purchase/refi volumes rise and 30-year mortgage <6.0% within 30 days; sell into a 25% rally or if monthly origination margins compress by >50bps.
• Implement a pair trade: long 2% KRE (regional bank ETF) vs short 2% NLY to express relative benefit of loan growth over MBS NAV risk, recalibrate after 30 days or if unemployment >6% or CPI surprises to upside.
