Mortgage rate projections for the next 5 years

Mortgage rates have fallen roughly 0.5 percentage point over the past year but are expected to remain elevated over the next five years because 30‑year fixed rates track the 10‑year Treasury; Deloitte’s baseline forecast (cited here) sees the 10‑year at or above about 4.1% through 2030, with Goldman and the CBO offering slightly different paths. Using Deloitte’s Treasury view and an assumed Treasury‑to‑mortgage spread in the ~2.1–2.5 percentage‑point range (historical ~1.7 in the 2010s, recent ~2.6), the article projects 30‑year mortgage rates around roughly 6.3%–6.5% by 2027 and sees little chance of a return to 3% in the next five years absent a major economic shock. Key risks to the call are deviations in 10‑year yields, a widening or narrowing of the spread, and shifts in Fed policy, all of which would materially affect housing affordability and refinancing activity.

Analysis

Mortgage rates have declined about 0.5 percentage point over the past year (Freddie Mac) but remain materially above pre‑pandemic lows because 30‑year fixed mortgages track 10‑year Treasury yields with a historical spread that has widened recently. As of Dec. 4 the 10‑year was 4.11% and the 30‑year fixed was 6.19% (spread 2.08pp), and recent spreads have hovered around 2.1–2.5pp versus the 2010s norm near 1.7pp.

Economists’ long‑run views diverge but cluster above prior lows: Deloitte expects the 10‑year to remain above 4.1% through 2030, Goldman Sachs projects 4.5% by 2035, and the CBO sees roughly 3.8–3.9% by 2030. Using Deloitte’s baseline plus a 2.1–2.5pp spread produces a five‑year 30‑year mortgage range near roughly 6.3%–6.5% (the article’s 2027 estimate 6.28%–6.48%), and no credible forecast in the piece predicts a return to 3% mortgage rates absent a major economic shock.

Persistently elevated mortgage rates imply continued pressure on housing affordability, lower refinance activity and rate‑sensitive earnings for lenders and builders. Key upside/downside risks that would materially change this outlook are large moves in the 10‑year Treasury, a narrowing/widening of the Treasury–mortgage spread, or a decisive shift in Federal Reserve policy or macroeconomic shocks.

Key Decisions for Investors

• Reposition rate‑sensitive allocations: reduce duration exposure in mortgage‑sensitive sectors and avoid relying on refinancing tailwinds given a central case of 30‑year mortgages near 6.3%–6.5% over the next five years
• Hedge interest‑rate risk by using duration or Treasury‑linked hedges (targeting protection if 10‑year yields rise above ~4.5%) and monitor the Treasury–mortgage spread for entry/exit signals
• For borrowers and mortgage exposure, prefer locking fixed rates now rather than waiting for a return to 3% rates, and if using ARMs align the initial fixed period with expected holding horizon
• Monitor three triggers to revise positioning: 1) a sustained fall of the 10‑year toward ~3.8%–3.9%, 2) a significant contraction of the Treasury–mortgage spread toward 1.7pp, and 3) clear changes in Fed guidance or recession indicators that would materially lower yields
• Avoid asymmetric bets that assume a rapid normalization to pre‑pandemic mortgage levels; maintain liquidity and stress‑test housing and credit exposures against the article’s outlined downside scenarios
