Surge in Mortgage Rates
Mortgage rates have reached their highest level since last August, as reported by Freddie Mac. The average rate on 30-year fixed home loans soared to 6.51 percent for the week ending May 21, up from 6.36 percent the previous week. By May 25, Bankrate indicated the national average had climbed to 6.65 percent, showcasing a 0.07 percent increase from the week prior.
This rise in rates follows the beginning of the Iran war in late February, conflicting with expert predictions of improved affordability in the U.S. housing market through lower borrowing costs. “Coming into the year, we anticipated a stronger spring season compared to 2025,” said Daryl Fairweather, Redfin’s chief economist. “Rates were lower year-over-year, wages outpaced home prices, and inventory was loosening. But the war in Iran emerged at a critical moment, causing rates to spike, gas prices to surge, and confidence to plummet.”
Consequently, the U.S. housing market is expected to remain sluggish over the summer following a disappointing spring, posing challenges for home sellers grappling with reduced demand and high competition.
A Look at Historical Mortgage Rates
Mortgage rates have fluctuated significantly since the pandemic. In 2020, rates dipped to 2.6 percent, sparking a nationwide homebuying surge. Rising inflation in 2022 led the Federal Reserve to implement an aggressive rate-hiking strategy, pushing mortgage rates up.
Between 2022 and 2023, rates averaged nearly double the pandemic lows, peaking at 7.8 percent in October 2023 for 30-year fixed mortgages. Although rates have lowered below 7 percent recently, high borrowing costs continue to contribute to the U.S. housing affordability crisis.
Experts initially forecasted a decline to 6 percent or less this year. However, the Iran war has disrupted expectations, resulting in a near nine-month high for mortgage rates in the week ending May 21, despite the gradual decline observed since last summer.
Whether rates will decrease or continue rising hinges largely on the situation in Iran. “It could go either way,” Fairweather stated. “The key question is the duration of the Iran conflict. Stabilization of the Strait of Hormuz and a drop in oil prices could ease inflation pressures, potentially leading to rates drifting toward 6 percent by year-end.”
Nonetheless, if the region remains unstable, rates could rise toward 7 percent or above.
Impact on Buyers and Sellers
The U.S. housing market was expected to rebound from winter with increased sales in the spring, fueled by lower mortgage rates and increased inventory. However, economic uncertainties linked to the Middle Eastern conflict, affordability challenges, and rising rates have hindered this resurgence. While there has been only a modest demand recovery, some positive trends can be observed.
“This season underperformed, but it wasn’t a defeat,” Fairweather remarked. “The war impacted the market.” New listings reached their highest April levels since 2022, with contract signings increasing by 4.5 percent. Despite adverse conditions, these trends persisted.
Jake Krimmel, a senior economist at Realtor.com, noted: “Rising rates, inflation, and low consumer confidence made it challenging. It poses questions about how the market would fare without the Iran war’s impact.” Although conditions in the housing market could have been better without the conflict, buyers are now adjusting to the ‘higher for longer’ rate environment, finding ways to manage the 6 percent rate.
Short-term projections indicate that the unexpected rate increase over recent months will impact demand, but optimism remains for a more stable market compared to the previous two summers. If demand signals hold, it could lead to a noticeable rise in closed sales during May and June, typically strong months for the market. However, geopolitical uncertainties and inflation could further influence mortgage rates and consumer behavior, potentially impacting home purchase dynamics.
