Mortgage rates hit 6.46% last week, marking a significant rebound from the three-year low reached in February. Homebuyers face renewed volatility as Federal Reserve policymakers wrestle with twin risks in a fragile geopolitical environment that's reshaping housing market dynamics. This move reflects not just the immediate tensions of the U.S.-Iran conflict, but deeper uncertainties about the economic trajectory facing policymakers.

The 57 basis point increase since February represents one of the sharpest moves in mortgage rates since the 2023 crisis, highlighting how geopolitical shocks can rapidly transmit to domestic credit markets. For a typical buyer of a $400,000 home with a 20% down payment, this increase translates to approximately $150 in additional monthly mortgage payment, significantly reducing purchasing power in a market where home prices have only just begun to moderate after years of sustained appreciation.

Mortgage Rates: Fed's War Dilemma Sparks Volatility Shift in Housing M

Federal Reserve officials expressed substantial concerns about the economic impact of the U.S. war with Iran at their last interest rate meeting, according to minutes released Wednesday. The discussions behind closed doors on March 17-18 occurred just weeks into the conflict that has since entered a fragile two-week ceasefire. This geopolitical uncertainty injects fresh complications into a housing market already showing mixed signals after three rate cuts in 2025 that had provided temporary relief to buyers.

The Federal Open Market Committee meeting concluded with a majority voting to leave interest rates unchanged in a range of 3.5% to 3.75%, where they've stood since December. But the tone of discussions marked a notable shift: almost all participants said upside risks to inflation and downside risks to employment were elevated. Many noted those risks increased after the Middle East conflict, creating a dilemma for central bankers who use higher rates to fight inflation and lower rates to stimulate the job market.
