- The average rate on a 30-year fixed mortgage rose for a fifth consecutive week to 6.46% — the highest since early September — up from 6.38% last week and sharply above the sub-6% rates seen in late February before the Iran war began
- Capital Economics downgraded its already bearish 2026 forecast for existing home sales, citing the rate jump fueled by Iran war inflation fears and rising benchmark Treasury yields
- The rate surge has materially reduced purchasing power for new buyers, who now face significantly higher monthly payments than they would have in late February when rates briefly dipped below 6%
- The housing market is entering its traditional peak spring season, but the combination of higher rates, elevated home prices, AI-driven job insecurity, and economic uncertainty threatens to keep both buyers and sellers on the sidelines
What Happened?
U.S. mortgage rates rose for a fifth straight week, with the average 30-year fixed rate climbing to 6.46% — the highest level since early September — according to Freddie Mac data. That is up from 6.38% last week and represents a sharp reversal from late February, when rates briefly fell below 6% before the Iran war broke out on Feb. 28. The Iran war has pushed oil above $100 a barrel and revived inflation concerns, driving up Treasury yields — to which mortgage rates are closely linked. Capital Economics responded by downgrading its already-bearish 2026 forecast for sales of previously owned homes, citing the rate increase. The spring homebuying season — typically the most active period for real estate transactions — is just getting underway, but market watchers are cautious about what the higher-rate environment means for transaction volumes.
Why It Matters?
The housing market has been one of the most rate-sensitive sectors of the U.S. economy, and a fifth consecutive weekly rate increase underscores just how completely the Iran war has reversed the mortgage market’s trajectory. As recently as late February, the industry was pricing in a gradual rate decline that would finally unlock the “lock-in effect” — the phenomenon where existing homeowners with sub-4% mortgages refuse to sell because they don’t want to trade into a higher-rate loan. With rates now back above 6.4%, that lock-in effect deepens, constraining inventory even as demand softens. Hannah Jones of Realtor.com framed the concern directly: “This fast-changing mortgage math, combined with general economic uncertainty, could keep more buyers on the sidelines as the typically busy spring market gets into full swing.” The simultaneous headwinds of elevated home prices, rising rates, AI-driven job insecurity, and general economic uncertainty make this one of the most difficult spring seasons the housing market has faced in years.
What’s Next?
Mortgage rates will remain elevated as long as the Iran war keeps oil prices high and Treasury yields rising. A resolution to the conflict that brings oil back below $80 a barrel could allow rates to fall meaningfully — potentially re-energizing the housing market in the second half of 2026. In the absence of that catalyst, the spring season is likely to see depressed transaction volumes with prices holding relatively firm due to ongoing inventory constraints. For homebuilders, the equation is particularly difficult: demand is softening but land and construction costs remain elevated, compressing margins. For real estate investment trusts and mortgage companies, the rate trajectory directly determines origination volumes and refinancing activity — both of which are effectively frozen at current levels. The housing market’s recovery has once again been deferred pending an Iran war resolution.
