FX.co ★ U.S. 30-Year Mortgage Rate Ticks Higher to 6.30%, Extending Housing Affordability Squeeze

The average contract interest rate for 30-year fixed-rate mortgages in the United States has risen to 6.30%, up from 6.19%, according to data updated on 18 March 2026. The move reflects a continued upward drift in borrowing costs that threatens to keep pressure on already stretched homebuyers.

The latest reading from the Mortgage Bankers Association’s 30-Year Mortgage Rate series underscores how sensitive the housing market remains to interest-rate fluctuations. Even modest increases in mortgage rates can significantly affect monthly payments, impacting affordability for first-time buyers and those looking to trade up.

With rates now at 6.30%, prospective borrowers face a higher cost of financing than in the prior period, which may weigh on purchase activity and refinancing demand. Market participants will be watching upcoming economic data and central bank signals closely for clues on whether mortgage rates will stabilize or continue to trend higher in the months ahead.
