FX.co ★ U.S. Mortgage Refinance Activity Slides as Index Falls to 627.1

Mortgage refinancing activity in the United States declined, with the Mortgage Refinance Index dropping to 627.1, down from a previous level of 687.3. The latest reading, updated on 16 September 2026, points to weakening demand for refinancing among U.S. homeowners.

The decrease in the index suggests fewer borrowers are opting to refinance their existing home loans, which may reflect less favorable rate dynamics, reduced incentive to lower monthly payments, or tighter financial conditions. Market participants and lenders will be watching upcoming data closely to see whether this decline marks the start of a longer trend or a short-term adjustment in refinancing activity.
