What it means for your shop

Lenders face a pinch: the 30-year mortgage at 6.66% is now 191 bps wide to the 10-year, compressing origination margins while the flat curve (41 bps) signals continued uncertainty around medium-term rate expectations and refinance incentives remain muted at current levels.
