U.S. Mortgage Applications Grow Despite Rising Rates: MBA

MBA weekly survey showed U.S. mortgage activity mixed: the market composite index rose 0.2% (SA) in the week to Nov. 21, the purchase index jumped 8% while the refinance index fell 6%, and refinance share declined to 53.4% of applications. Adjustable-rate share rebounded to 7.9% and the average 30-year fixed rate climbed to 6.40% from 6.37% (highest since early October); government purchase applications (FHA/VA/USDA) rose 9%. Rising rates have curbed refinance demand despite stronger purchase activity, pointing to continued affordability pressures even as demand in government-backed channels strengthens.

Analysis

Market structure: Rising purchase applications despite a 30‑yr rate at 6.40% (fourth weekly rise) implies resilient demand concentrated at the entry-level/government‑insured segment (FHA/VA/USDA up 9%). Winners: entry‑level homebuilders, community banks and originators focused on government programs; losers: refinance‑dependent mortgage originators and mREITs exposed to negative convexity and servicing runoff. Expect modest upward pressure on agency MBS yields and wider mortgage spreads if rates keep drifting higher by 20–50 bps.

Risk assessment: Near term (days–weeks) tail risk is a rate shock (>40bp move) that would instantaneously knock purchase momentum and widen spreads; medium (months) risk is regulatory changes to FHA/VA underwriting or caps that would reallocate demand; long run (quarters) affordability constraints (loan size falling) signal structural demand compression for higher‑end builders. Hidden dependency: continued labor/land supply constraints can keep home prices sticky even as loan sizes shrink.

Trade implications: Favor long exposure to affordable‑home builders and short or hedge mREITs/mortgage originators; use ~3–6 month horizons with defined rate triggers (30‑yr >6.6–6.8%). Options: use short‑dated put spreads on mREITs and call spreads on entry‑level builders to control risk. Cross‑asset: buy protection in duration (2s10s steepener) if purchase momentum falters; expect slight USD support if rates re‑price higher.

Contrarian angles: The market expects higher rates to crush purchases — current data shows purchase resilience concentrated in government loans and smaller loan sizes, so pure cyclical homebuilder shorts may be overdone. Historical analog: 2018 saw temporary resilience then pullback; if mortgage rates stabilize ≤6.3% within 6–8 weeks, builders can re-rate. Unintended consequence: aggressive shorting of mREITs could be painful if agency MBS spreads tighten on sustained purchase demand.

Key Decisions for Investors

• Establish a 2% long position in DHI (DR Horton) and 1% long in LEN (Lennar) as a combined 3% allocation targeting 20–30% upside over 6–12 months; trim or stop‑loss if 30‑yr mortgage >6.8% or MBA weekly purchase index falls >10% for two consecutive weeks.
• Establish a 2% tactical bearish exposure to mREITs (AGNC or NLY) via a 3‑month put‑spread (buy 1 ATM put, sell lower strike for premium offset) sized to limit max loss to ~2% of portfolio; unwind if 10‑yr Treasury yield drops >25bps or agency MBS spreads tighten >15bps.
• Implement a pair trade: long 1–2% in an agency MBS ETF (MBB) for carry versus a 1–2% short in a refinance‑exposed mortgage originator (e.g., RKT or a bank with high mortgage pipeline exposure) for 3–6 months; re‑evaluate if the government purchase index falls for three consecutive weeks.
• Monitor weekly: MBA purchase index, government purchase subindex, and 30‑yr mortgage rate thresholds at 6.3%, 6.6%, 6.8%; use these triggers to scale positions (add at stabilization ≤6.3% over two weeks, reduce if >6.6% persistence).
