U.S. mortgage rates climbed to 7.5 percent, a level last seen during the mid-2000s housing boom, triggering a sixth consecutive week of declining home purchasing activity.
Each 25 basis point increase in mortgage rates adds hundreds of dollars to monthly payments on an average U.S. home, directly compressing buyer affordability. The sustained rise in borrowing costs reflects the broader Treasury market's recalibration to higher long-term yields, as the 10-year benchmark—the primary anchor for mortgage pricing—faces upward pressure from elevated inflation expectations.
From a fixed-income perspective, the climb introduces acute duration risk for mortgage-backed securities portfolios. As rates rise, MBS duration extends, magnifying sensitivity to further yield increases and straining valuations for institutional holders. The flattening of prepayment expectations as refinancing volumes collapse further complicates portfolio hedging.
Existing homeowners with sub-4 percent fixed rates face a powerful disincentive to sell, tightening inventory across most markets. New construction activity, while sustained in pockets, cannot offset regional demand shortfalls. The mismatch is starving the secondary market of turnover.
The Federal Reserve continues to monitor inflation data for signs of progress toward its 2 percent target. Persistent inflation could force an extended hold in policy rates, anchoring long-term yields at elevated levels and keeping mortgage rates in the 7 percent-plus zone.
