Mortgage Rates Slide After Iran War Spike, Offering Spring Homebuyers Relief

After spiking in March amid the Iran conflict and renewed inflation concerns, mortgage rates have reversed course—offering spring homebuyers a timely break. According to recent data, the average 30-year fixed mortgage rate dipped to a one-month low as market volatility eased following the initial shock of the U.S.-Iran conflict.

The U.S.-Israeli military strikes on Iran that began February 28, 2026, triggered immediate turbulence in financial markets, pushing mortgage rates upward from recent lows. Just two days before the attacks, on February 26, the average 30-year fixed mortgage rate stood at 5.98%—the lowest level since September 2022, according to Freddie Mac’s Primary Mortgage Market Survey. But, by March 12, that rate had climbed to 6.11% as oil prices surged and inflation expectations rose.

This increase represented the biggest weekly jump since April 2025, when former President Trump’s “Liberation Day” tariffs caused bond yields to spike. On a $400,000 mortgage, the rise from 5.98% to 6.11% added roughly $31 per month—or over $11,000 over the life of a 30-year loan—placing additional strain on first-time buyers already facing high home prices.

The primary driver behind the rate volatility lies in the connection between oil markets and inflation. Oil prices jumped 25% from $71.23 per barrel on March 2 to $119.48 on March 9—the first time exceeding $100 since Russia’s invasion of Ukraine in 2022. Higher oil prices tend to lift inflation expectations, which in turn push Treasury yields and mortgage rates higher.

Despite the initial spike, recent trends show mortgage rates retreating from their March peak. As geopolitical tensions stabilized and inflation concerns moderated, rates began to decline, offering renewed affordability for spring homebuyers. This reversal has injected momentum into a housing market that had been stalled by elevated borrowing costs for months.

Industry analysts note that even as the Iran conflict introduced short-term volatility, the long-term direction of mortgage rates will depend more heavily on domestic economic indicators—particularly employment data and inflation trends. If job growth remains steady and inflation continues to cool, experts suggest mortgage rates could remain favorable for homebuyers through the remainder of 2026.

For now, the recent dip in rates provides a window of opportunity for those looking to enter the market. With spring traditionally a peak season for homebuying, the improvement in affordability could help unlock pent-up demand and support increased transaction activity in the coming weeks.
