U.S. mortgage rates rise as 30-year fixed rate hits 6.66%

U.S. mortgage rates have trended higher, with the benchmark 30-year fixed-rate mortgage climbing to approximately 6.66%, according to Freddie Mac. This increase marks a stall in the recent downward drift of borrowing costs and brings rates close to their recent yearly highs. The 15-year fixed-rate mortgage also saw an increase, rising to roughly 5.98%.

Several economic factors are influencing these rates, including elevated 10-year Treasury yields, inflation expectations, and Federal Reserve policy. Recent data from the Bureau of Economic Analysis showed inflation rising by 0.2% in July, bringing the year-over-year rate to 3.7%, which remains above the Federal Reserve's 2% target. Additionally, geopolitical tensions and concerns regarding U.S. national debt have contributed to higher bond yields.

The rising costs are impacting housing affordability and market dynamics. A phenomenon known as the ‘lock-in effect’ persists, as homeowners with low-interest mortgages from previous years are reluctant to sell and refinance at higher current rates. This has resulted in tight housing inventory and a slump in home sales.
