Briefing

The US 30-year fixed mortgage rate rose to 6.46% in the week to April 2, its fifth consecutive weekly increase, as the Iran war sustained upward pressure on borrowing costs. The rate had briefly fallen to 5.98% on February 26, its lowest since 2022, before conflict in the Middle East disrupted bond markets. Refinance demand has fallen more than 40% over the past month, according to CNBC, as the rate reversal sidelines both buyers and existing homeowners.

Iran war erases a four-year low in US mortgage rates

The 30-year fixed US mortgage rate reached 6.46% as of April 2, according to Freddie Mac data cited by Reuters and Bloomberg, marking five straight weeks of increases and reversing what had briefly looked like a meaningful opening for prospective homebuyers.

The rate had touched 5.98% on February 26, its lowest level since 2022, according to MarketWatch. The 48-basis-point move since that date represents a material deterioration in affordability at a moment when many buyers had begun to re-engage with a market that had been suppressed by elevated rates throughout 2024 and 2025.

The Iran war has been the primary driver of the reversal. Conflict in the Middle East has pushed inflation expectations higher and kept Treasury yields elevated, feeding through directly to mortgage pricing. The New York Times and CNN have both attributed the sustained rise to war-related anxiety in fixed-income markets.

The consequences for housing activity are already visible. Refinance applications have dropped more than 40% over the past month, according to CNBC, as the brief window of sub-6% rates that briefly made refinancing economically rational for many borrowers has closed. Purchase demand faces analogous headwinds, with CBS News reporting that buyers who had structured plans around lower rates are being caught out by the renewed rise.

The trajectory of mortgage rates from here depends heavily on how the conflict develops and its knock-on effects for US inflation and Federal Reserve policy. Until those questions are resolved, the housing market faces a ceiling on any recovery in transaction volumes.

Analysis

Five consecutive weeks of mortgage rate increases, combined with a 40%-plus collapse in refinance demand, removes the refinance-driven fee income that had provided a partial cushion for mortgage originators and servicers. With rates now 48bps above the February trough, the addressable refinance pool has effectively closed again, and purchase demand faces an affordability wall that was thin even at 5.98%. Non-bank originators with higher fixed-cost structures are most exposed to the volume compression.
The Iran war energy shock is now transmitting simultaneously through mortgage rates, oil prices, fuel surcharges, and consumer sentiment. With OECD projecting 4.2% US inflation, the Fed cannot cut rates to relieve housing affordability without abandoning its inflation mandate. This stagflationary lock-in is credit-negative for homebuilders: they face both a financing cost problem for buyers and input cost inflation on materials and logistics, with no policy relief plausible in the near term.

OECD warns Iran war will push US inflation to 4.2%, erasing global growth gains

The OECD's 4.2% US inflation forecast driven by the Iran war energy shock is the macro constraint that prevents any Fed rate relief for mortgage borrowers. The conflict-driven oil price surge is the common cause behind both the inflation projection and the five-week mortgage rate rise.

Iran war hammers consumer sentiment as Dow flirts with correction

The sharp drop in consumer sentiment documented in late March, driven by the same Iran war dynamics, compounds the mortgage rate problem: buyers who are already psychologically retreating from major purchases now face a near-half-point financing cost increase, making the demand destruction in housing more durable than either factor alone would produce.
