Mortgage rates climbed to 6.66% as of late July 2026, marking the highest level in over a year, with forecasters warning that rates are likely to move higher in August as inflation concerns and geopolitical tensions persist.
According to Freddie Mac’s Primary Mortgage Market Survey, the 30-year fixed-rate mortgage averaged 6.66% for the week ending July 30, up from 6.58% the previous week. This marks a significant jump from the same time last year, when rates averaged 6.72%.
The August outlook for mortgage rates appears challenging for prospective homebuyers. Mortgage interest rates are expected to move higher this month, driven by ongoing geopolitical uncertainty and persistent inflation pressures. The war in Iran, which has disrupted global trade and driven up commodity prices including oil, continues to influence mortgage rates. When investors worry about inflation, they demand higher returns on bonds, which in turn pushes mortgage rates upward.
Inflation remains a key concern. The June Personal Consumption Expenditures index came in at 3.7%, well above the Federal Reserve’s 2% target. This elevated inflation is keeping pressure on bond yields, which mortgage lenders use as a benchmark for setting rates.
The Federal Reserve held its benchmark interest rate steady at 3.5% to 3.75% at its July 28-29 meeting, and the central bank is not expected to take action through the remainder of 2026. However, mortgage rates don’t move in lockstep with Fed policy. Instead, they more closely track the 10-year Treasury yield, which closed at 4.67% as of July 29, compared to 4.37% a year prior. Mortgage lenders add a spread to the Treasury yield to cover their costs and risk, resulting in the higher rates consumers see today.
Looking ahead, forecasters don’t expect significant relief for borrowers. Fannie Mae’s July Housing Forecast puts the 30-year fixed rate at 6.4% by the end of 2026 and predicts average rates to remain near 6.2% to 6.3% through 2027. The Mortgage Bankers Association forecasts 30-year fixed mortgage rates of 6.5% in the third and fourth quarters of 2026. These projections suggest that mortgage rates are likely to remain elevated for the foreseeable future unless inflation shows sustained signs of easing or geopolitical tensions ease significantly.
