What are today's mortgage interest rates: March 24, 2026?

The average 30-year mortgage rate is 6.25% and the average 15-year rate is 5.75% as of March 24, 2026; average refinance rates are 6.70% (30-year) and 5.76% (15-year). Rates have risen noticeably since late February amid recent unemployment and inflation releases and a continued Federal Reserve policy pause, though they remain materially lower than in March 2025. Borrowers are advised to shop lenders and check credit profiles to seek better offers or assess refinance savings.

Analysis

Recent repricing in long-duration consumer finance (mortgages and related securitized paper) propagates across the housing value chain through three linked mechanisms: hedging cost shock for originators, duration-driven mark-to-market for mortgage investors, and a demand-side cut in prospective buyers who become price-sensitive. Originators face a wedge between locked pipeline rates and current funding/hedge costs that can force liquidity draws or wider retail spreads; small nonbank lenders without captive funding are the first marginal sellers of loans and servicing, compressing their equity value quickly.

On the investor side, agency MBS convexity amplifies moves in underlying yields, making short-term total returns dominated by mark-to-market while carry accrues slowly; that dynamic favors capital structures and strategies that harvest carry with disciplined convexity hedges rather than outright duration punts. For housing supply, a prolonged period of lower transaction velocity (fewer refinances + fewer purchases) will shift the imbalance toward sellers, increasing inventories and pressuring new construction starts within two to four quarters.

The consensus sensitivity is to a single directionally higher-rate narrative; the contrarian view is that prepayment behavior and borrower lock-in materially blunt duration risk in the near term, creating windows where carry plus spread compression outperforms overt long-duration risk. Key catalysts to watch are rate term premium moves, agency TBA flows, and incremental data on refi pull-through and purchase application trends — any of which can flip P/L profiles in days rather than months.

Key Decisions for Investors

• Buy iShares MBB (agency MBS ETF) size 3-5% NAV, horizon 3-6 months. Rationale: harvest elevated carry while hedging with a 2yr Treasury short to control duration; target gross return 4-8% vs downside 6-10% if rates gap higher — cut to flat if TBA spreads widen >25bps.
• Pair trade: short regional banking exposure (e.g., ZION, FRC, or a regional bank basket) vs long BAC (1.5:1 notional) for 3-6 months. Rationale: regional deposit flight and higher funding costs compress NIMs faster at smaller banks; expect relative underperformance of regionals by 15-25% in stress scenario while BAC acts as a funding/scale hedge.
• Short ITB (homebuilders ETF) and long ML M (Martin Marietta Materials) or similar materials/aggregates supplier, horizon 6-12 months. Rationale: weaker demand for new construction will hit builder equities before materials via guidance cuts; target pair return 20%+ if starts drop, with limited downside if builders quickly reprice margins.
• Directional mortgage REIT option structure: buy AGNC (or NLY) with protective puts (3-6 month tenor) sizing at 1-2% NAV. Rationale: capture potential spread tightening and carry while capping tail risk from a rate shock; target asymmetric payoff of 15-30% upside vs capped loss ~2-4% depending on hedge cost.
