Mortgage Rates Rise Again on Saturday, September 12, 2026

Mortgage and refinance interest rates edged higher on Saturday, September 12, 2026, extending an upward move from the prior session. The latest reading from Yahoo Finance shows the second consecutive daily increase, a signal that borrowing costs remain sensitive to broader market forces.

For prospective homebuyers, even modest rate changes can affect monthly payments and affordability calculations. Homeowners weighing a refinance face a similar equation, since a higher rate can reduce or eliminate the savings that might come from replacing an existing loan.

Mortgage rates often track the yield on government bonds, which can shift with inflation data, Federal Reserve expectations and investor demand for fixed-income assets. When those underlying yields rise, lenders typically adjust their offered rates in response, though the exact timing and size of changes can vary by lender and loan product.

The move marks another day of upward pressure rather than a reversal. Whether the trend continues will depend on upcoming economic reports and how financial markets interpret them. For now, borrowers comparing options may want to monitor daily quotes closely, as even small swings can influence long-term costs.
