Mortgage Rates Today, March 28, 2026: 30-Year Fixed Ends Week at Six-Month Highs as Yields Rise
Mortgage rates in the U.S. squeezed higher by week’s end—Freddie Mac put its benchmark 30-year fixed at 6.38% while Mortgage News Daily’s read was a steeper 6.64% on Friday. The two surveys differ in method, but this week, both tracked another bump in borrowing costs. The timing stings: just as the spring selling season kicked into gear, higher rates have pushed up monthly payments for buyers and made refinancing less attractive. Mortgage rates typically move with the 10-year U.S. Treasury yield, the key government benchmark for long-term borrowing. Lately, that yield’s been climbing, fueled by inflation worries tied to oil.
