US long-term mortgage rates climb to 6.51%

Average U.S. long-term mortgage costs increased in the latest weekly reading, according to data released by Freddie Mac on May 21, 2026. The company’s survey showed the benchmark 30-year fixed-rate mortgage averaging 6.51%, indicating elevated borrowing costs for many prospective and current homeowners.

Freddie Mac’s weekly figures are widely followed in housing and financial markets because they reflect typical terms offered on conventional mortgage products across the country. The reported increase in the 30-year rate was highlighted in national business coverage on May 21, underscoring a shift in financing conditions for home purchases.

Alongside the 30-year loan, Freddie Mac reported that the average 15-year fixed-rate mortgage stood at 5.85% as of May 21, 2026. This shorter-term product is often used by borrowers seeking faster payoff schedules and potentially lower total interest costs compared with longer maturities.

The 5.85% average for 15-year fixed mortgages confirms that higher borrowing costs are not limited to the standard 30-year loan. Both key products tracked in the weekly survey showed elevated levels, affecting options for homebuyers weighing different repayment horizons.

The latest mortgage figures came as the U.S. 10-year Treasury yield traded near 4.6% in midday activity on May 21, 2026. Treasury yields are closely watched by lenders and analysts because they are commonly used as a reference point when pricing fixed-rate home loans.

With the 10-year yield around 4.6%, the relationship between bond-market benchmarks and mortgage rates was a focus of the same market coverage. Movements in Treasury yields can influence funding costs for lenders and, in turn, the interest rates offered to consumers on long-term mortgages.

The reported averages of 6.51% for 30-year fixed mortgages and 5.85% for 15-year fixed mortgages imply higher monthly payments for many borrowers compared with lower-rate environments. This affects affordability for households considering entering the housing market.

For homeowners evaluating whether to refinance existing loans, the current averages suggest less favorable conditions than periods of lower rates. The latest data highlight the importance of prevailing bond yields and weekly mortgage surveys in shaping financing decisions across the housing market.
