FX.co ★ U.S. Mortgage Refinance Activity Cools as Index Slips to 687.3

The U.S. Mortgage Refinance Index declined to 687.3, down from a previous reading of 732.6, according to data updated on 09 September 2026. The latest figure signals a moderation in refinancing activity across the U.S. mortgage market.

The drop in the index suggests fewer homeowners are pursuing refinancing compared with the prior measurement period, reflecting a shift in demand after the earlier, higher level of 732.6. Market participants will be watching upcoming readings to determine whether this move marks the start of a broader slowdown in refinance activity or a temporary adjustment in the mortgage landscape.
