Mortgage rates surge to nearly four-week high as Iran headlines impact markets

• The 30-year fixed mortgage rate climbed seven basis points to 6.45%, the highest level since April 3, as rates follow the U.S. 10-year Treasury yield
• Despite rate volatility, mortgage applications to purchase homes last week were up 1% week-over-week and 21% higher compared to the same period a year ago
• More housing supply is entering the market with prices easing in some areas, as homebuyers appear to be adapting to the higher rate environment and economic uncertainty from ongoing conflict

SUMMARY: Mortgage Rates Climb on Iran-Related Geopolitical Tensions

Mortgage rates surged to nearly a four-week high on Wednesday, April 29, 2026, driven by escalating geopolitical tensions with Iran. The average 30-year fixed mortgage rate rose seven basis points to 6.45%, the highest level since April 3. This increase followed President Trump's announcement that the U.S. would maintain its naval blockade against Iran until a nuclear deal is reached.

Key Market Drivers:

Mortgage rates, which track the 10-year U.S. Treasury yield, reversed course after hopes for de-escalation in the Iran conflict dissipated. According to Matthew Graham of Mortgage News Daily, the market had positioned for reduced tensions just over a week ago, but renewed escalation fears triggered the sharp rate increase.

Housing Market Impact:

Despite higher rates since the war began, mortgage applications for home purchases showed resilience, rising 1% week-over-week and surging 21% year-over-year, according to the Mortgage Bankers Association. The housing market is seeing increased supply and moderating prices in some areas, with real estate brokerages reporting stronger buyer traffic, suggesting consumers may be adapting to the elevated rate environment.

Fed Policy Context:

The Federal Reserve was not expected to adjust interest rates at its Wednesday meeting, leaving mortgage rate movements primarily dependent on geopolitical developments and bond market reactions.

Outlook:

Uncertainty remains regarding whether this rate surge will persist and how it might affect the spring housing market. The continued Iran conflict and economic uncertainty are creating volatility that could impact both buyer demand and overall housing activity in the coming weeks.
