Key Highlights

  • For housing stocks, one number matters more than almost any other: the rate on a 30-year mortgage.
  • Consumer Discretionary, the sector that houses homebuilders and home-improvement retailers, was among the S&P 500 groups that fell hardest.
  • Crude prices rose after President Trump rejected Iran's plan to reopen the Strait of Hormuz, reviving Inflation worries.
  • The 10-year Yield ended the session near its highs, and futures kept pricing more Fed tightening.

The average 30-year Mortgage rate has climbed to its highest level since January 2025, and on Monday, September 28, homebuilders and home-improvement names felt the pressure as Treasury yields hit multi-year highs.

The number housing investors fear

For housing stocks, one number matters more than almost any other: the rate on a 30-year mortgage. According to Schwab (NYSE:SCHW), the average 30-year mortgage rate has climbed above a closely watched threshold for the first time since January 2025. That puts home loans at their most expensive in more than a year and a half.

The driver is the bond market. Mortgage rates tend to track the 10-year Treasury yield, and on Monday that yield climbed to its highest level since 2007. The 30-year Treasury Yield hit its highest since 2004. When the benchmarks lenders price off rise, borrowers pay more, and monthly payments on a new home balloon.

Homebuilders under pressure

Home Depot (NYSE:HD), a member of the Dow Jones Industrial Average, slipped again on Monday, with no company-specific news to explain it. The pattern is familiar. When borrowing costs rise, fewer people buy homes, fewer move, and fewer take on big renovation projects financed with credit. That hits builders' order books and home-improvement sales at the same time.

Consumer Discretionary, the sector that houses homebuilders and home-improvement retailers, was among the S&P 500 groups that fell hardest. The broader market offered no cushion: the S&P 500 fell 59.72 points to 7,683.69 and the Dow dropped 347.11 points to 51,481.51.

The Fed is not helping

The Federal Reserve raised rates at its September meeting, its first hike in three years, in a unanimous vote under Chair Kevin Warsh. Warsh said: "Inflation is too high and has been for too long." Futures now price a strong majority chance of another hike at the October 28 meeting, according to several market trackers.

Oil adds another layer. Crude prices rose after President Trump rejected Iran's plan to reopen the Strait of Hormuz, reviving inflation worries. Fed Governor Lisa Cook said in a speech on Monday: "I expect to see continued pressure on inflation from the AI build-out … and from the pass-through of higher oil prices." For housing, that signals little relief from rates any time soon.

Commercial real estate feels it too

It is not just homes. CoStar Group (NASDAQ:CSGP)'s own data showed third-quarter Commercial Real Estate Demand "slightly negative, with net absorption expected to give back 2.7 million square feet,", and CoStar shares slid on Monday. Higher financing costs weigh on property values across the board.

Any relief for housing-related stocks would likely depend on the Bond Market turning, and on Monday there was no sign of that. The 10-year yield ended the session near its highs, and futures kept pricing more Fed tightening. Schwab's Nathan Peterson put the broader point simply: "If Treasury yields pull back (or at least stop moving higher), this could help provide a lift to stocks."

Case-Shiller and consumer confidence test housing

Tuesday brings the Case-Shiller home price index, alongside consumer confidence and the August JOLTS job-openings report. Wednesday's August PCE inflation data will be closely watched for signs that the Fed must keep hiking. Thursday adds construction spending and the ISM Manufacturing survey, and Friday's September jobs report could move Treasury yields, and with them mortgage rates, in either direction.
