Mortgage Rates Spike Amid Iran Tensions, Prompting New Housing Legislation

On the week of July 16, 2026, the average rate on a 30-year fixed mortgage rose to 6.55 %, the highest level in nearly a year. The increase followed renewed fighting in Iran that unsettled bond markets, pushing 10-year Treasury yields higher. Consequently, pending home sales fell 5.4 % month-over-month in June, and mortgage applications dropped 7 % week-over-week, according to the Mortgage Bankers Association. The National Association of Realtors reported a 0.3 % year-over-year decline in pending sales.

Higher borrowing costs, combined with a record-high national median home price, have strained first-time buyers. Inflation eased to 3.5 % in June from 4.2 % in May, but rising oil prices—gasoline jumped 15 cents to $3.94 per gallon—have revived inflation concerns, keeping mortgage rates elevated.

Lawrence Yun, chief economist of the National Association of Realtors, linked the rate surge to reduced market optimism. Zillow senior economist Kara Ng noted that rates are “caught between cooler inflation data and renewed energy risks.” Zillow projects rates will ease modestly to 6.4 % by the end of 2026, still above last year’s levels. In response to the housing-affordability bill that passed without President Donald Trump’s signature, Trump posted that the law was “of minor importance compared to lower interest rates.”

Critics argue the new bipartisan legislation—designed to expand housing supply and limit private-equity purchases of single-family homes—fails to address the primary barrier for buyers: mortgage rates, which are set by the bond market rather than congressional action.
