Key Highlights

● Long-term Treasury yields jumped after the Fed's decision.

● The average 30-year fixed mortgage rate had already been rising.

● Housing-linked stocks lagged on the day.

● Higher yields make affordability tougher for buyers.

Homebuyers had another reason to wince after the Federal Reserve's decision, as long-term Treasury yields, which help set mortgage rates, jumped. The 10-year Treasury yield posted its biggest daily gain in a month, pushing past a key psychological threshold, and the 30-year yield also rose.

Because 30-year fixed mortgage rates tend to track the 10-year yield, that move puts upward pressure on borrowing costs for home loans, which were already climbing over the past month according to mortgage trackers.

The Fed's Role

The Fed left its benchmark rate range unchanged in a 10-2 vote, but the decision leaned hawkish, with Governor Lisa Cook and Cleveland Fed President Beth Hammack dissenting in favor of a hike. The statement said economic activity is expanding at a strong pace while inflation remains elevated.

The Fed does not set mortgage rates directly, but its policy outlook influences the long-term yields that lenders use as a benchmark, and Fed Chair Kevin Warsh said financial and credit conditions have tightened for some households and businesses.

Housing-Linked Stocks Lagged

Rate-sensitive sectors lagged, with real estate among the weakest S&P 500 sectors, alongside utilities and consumer staples, while regional banks slipped as higher yields weighed.

Lennox International, which makes heating and cooling systems used in homes, tumbled after cutting its earnings guidance sharply, and Whirlpool slipped after an analyst downgrade citing weak demand for big-ticket home goods.
