US Mortgage Rates Climb to 6.64% After Hawkish Fed Signal Despite Easing Oil Prices

American homebuyers continue to face an expensive borrowing environment as the summer homebuying season reaches its peak. The average interest rate on a 30-year fixed purchase mortgage stood at 6.64% on June 24, 2026, according to Zillow data — up from 6.632% the previous day. Freddie Mac's weekly Primary Mortgage Market Survey placed the 30-year rate at 6.47% as of June 18, down five basis points from the prior week, while Bankrate's lender survey held at 6.48%.

The recent upward drift in daily rates is notable because it occurred despite a development that would normally push rates lower: news that a potential end to the war in Iran appears imminent, which eased oil prices and reduced upward pressure on Treasury yields. WTI crude fell to roughly $71 per barrel. The reason rates rose anyway lies in the Federal Reserve's June 17 meeting — not because the central bank held rates steady, which was widely expected, but because of the hawkish tone in its updated economic projections, where a majority of policymakers now anticipate a rate hike later in 2026 rather than a cut.

The broader inflation picture remains the dominant force. May CPI came in at 4.2% annually, the highest in over three years, while the May jobs report showed employment growing by 172,000 — outpacing expectations and reinforcing the case for elevated rates. As Cotality chief economist Selma Hepp noted, mortgage rates are unlikely to fall meaningfully until inflation cools and long-term yields move decisively lower, regardless of Fed action.

The affordability strain is significant. Based on a 20% down payment and a 6.48% rate, the monthly principal and interest payment on a median-priced home now consumes about 24% of the typical family's monthly income, according to Bankrate analysis. The median existing-home price reached an all-time high of $429,300 in May, per the National Association of Realtors, though home price growth has slowed sharply — the S&P Cotality Case-Shiller index showed national prices growing just 0.7% over the past year, the weakest reading since 2011. More than half of the 20 major US housing markets recorded year-over-year price declines, signalling a broadening housing slowdown.
