Mortgage Rates Rise Amid Iran Tensions and Oil Price Surge

Average rates for 30-year fixed home loans increased to 6.49% for the week ending July 9, a rise of 6 basis points from the previous week's 6.43%, according to Freddie Mac. This uptick reverses a recent trend of stable or declining rates and impacts homebuyer affordability. For comparative context, rates averaged 6.72% during the same week in 2025.

The increase in mortgage rates is directly linked to geopolitical developments involving the U.S. and Iran. A fragile peace deal between the two nations reportedly disintegrated this week, leading to mutual airstrikes. This escalation has heightened concerns about inflation, particularly through its effect on oil prices. U.S. crude oil prices surged to $76 per barrel following President Donald Trump's remarks on Wednesday, declaring the agreement with Iran "over" and criticizing its leadership. This marks the largest single-day price increase for oil since early June.

Sam Khater, Freddie Mac's chief economist, noted that while mortgage rates have been relatively stable recently, economic growth and housing affordability continue to improve for homebuyers. However, the current market dynamics suggest otherwise. Joel Berner, a senior economist at Realtor.com®, explained that the primary driver for inflation and subsequent higher interest rates is the price of oil. The deterioration of the situation in Iran has placed mortgage rates on an upward trajectory, countering earlier expectations of a retreat.

Given the looming threat of inflation, the Federal Reserve is unlikely to intervene by lowering interest rates, even with a recent soft jobs report. This economic outlook suggests that mortgage rates may continue to face upward pressure, further challenging prospective homebuyers. Berner predicts that the trend observed in Freddie Mac's latest report will likely persist.
