Mortgage and refinance interest rates today, March 14, 2026: These are not 'normal world' rates

The national average 30-year fixed mortgage rate is 6.08% (Zillow), up 10 basis points from last weekend, while the 15-year fixed is 5.62% (+12 bps); Zillow's 30-year refinance average is 6.24%. Rates have risen as Treasury yields climb amid oil-driven inflation fears tied to the Middle East conflict, even as forecasts (MBA/Fannie Mae) project ~6.0–6.1% through the near term. Mortgage rates remain below the January 2025 peak above 7% and have been gradually drifting down since late May 2025; refinance rates are generally higher than purchase rates.

Analysis

The geopolitical shock is transmitting to mortgage markets through the inflation channel rather than the classic flight-to-safety channel: a jump in oil raises near-term CPI expectations and breakevens, which lifts nominal long yields and forces mark-to-market losses in long-duration, convex bond instruments (including long-dated agency MBS). Because mortgage pipelines are rate-sensitive, origination volumes and lock-ins will reprice within days, but the balance-sheet and valuation effects (servicing rights, MBS inventories) play out over 1–3 quarters as issuers digest higher funding costs.

Winners and losers are non-linear: upstream energy producers and integrated E&P benefit within weeks of sustained higher oil, while homebuilders, mortgage originators, and regional banks with large MBS/servicing exposure are vulnerable to both immediate demand destruction and longer-term credit repricing. A less-obvious beneficiary is government-guaranteed MBS relative to private-label product — tighter private mortgage issuance widens market share for GSEs and could compress spreads on agency paper even as rates rise.

Key risks and catalysts: a rapid diplomatic de‑escalation, coordinated SPR release, or a weaker-than-expected CPI print could reverse the inflation impulse within days and trigger sharp tightening in breakevens (bad for TIPS, good for long MBS). Conversely, persistent oil above recent levels for multiple months forces the Fed to keep rates higher for longer, amplifying convexity losses in agency MBS and pushing housing activity into a protracted slowdown over 3–12 months.

Key Decisions for Investors

• Buy iShares TIPS Bond ETF (TIP) — 12–24 month trade. Rationale: inflation breakevens should reprice higher if oil remains elevated; TIP gains from rising breakevens and real yield compression. Position sizing: 2–4% portfolio, take profits at +12–15%, stop-loss -6%. Risk: disinflation/SPR release can produce 5–8% drawdown.
• Short iShares MBS ETF (MBB) via outright short or buy 3-month puts — 1–3 month trade. Rationale: agency MBS suffer convexity and duration losses as nominal yields climb; expect 3–8% downside if 10–25bp move in 10y yields persists. Position sizing: 1–2% portfolio equivalent, tighten if 10y moves >40bp in opposite direction.
• 2s/10s steepener using futures (sell 2y TU, buy 10y TY) — tactical 2–8 week trade. Rationale: inflation scare pushes long yields faster than front end while Fed remains data‑dependent, creating steepening; target 15–30bp steepening. Risk management: cut if front-end yields rise >25bp relative to long end (front-end dominance) and cap exposure to 1–2% notional.
• Short public homebuilders (PHM or DHI) — 3–6 month trade. Rationale: higher sustained mortgage costs reduce purchase demand and margins; target downside 10–25% with catalysts tied to sequential decline in weekly rates and builder order print. Risk: idiosyncratic pricing actions or incentive programs can produce sharp rebounds; use 15–20% stop-loss and keep exposure small (1–3%).
