FX.co ★ U.S. Mortgage Market Index Slides to 347.1, Signalling Cooler Housing Activity

The U.S. Mortgage Market Index declined to 347.1, down from a previous reading of 389.6, indicating a notable cooling in mortgage-related activity. The latest figure, updated on 18 March 2026, underscores a slowdown in demand within the U.S. housing finance sector.

The drop in the index suggests fewer applications or reduced momentum in mortgage borrowing compared with the prior period. While no specific drivers were disclosed alongside the data, the move lower from 389.6 to 347.1 points to a more cautious environment for home financing, with potential implications for lenders, homebuyers, and the broader housing market in the United States.
