Mortgage Rates Jump to 7.28% — Biggest Weekly Spike in Nearly Four Years

Mortgage rates just posted their biggest one-week jump in nearly four years. The average 30-year fixed rate climbed to 7.28% this week, up from 7.03% last week, according to Freddie Mac data released Thursday, October 1 — the sixth straight weekly increase, and the highest reading since November 2023, per Reuters coverage.

The driver is the bond market. The 10-year Treasury yield hit its highest level in nearly a quarter century this week after revised data showed the economy grew faster in the first half of the year than previously estimated, with inflation still running more than a percentage point above the Federal Reserve's 2% target. Investors now expect at least one more Fed rate hike this year, and the ongoing war with Iran plus elevated government spending and heavy AI data-center investment are adding to inflation pressure.

The 15-year fixed rate rose to 6.60% from 6.42%. Homebuilder stocks are feeling the pain: Barron's notes the iShares U.S. Home Construction ETF fell 8.1% in September, its worst September since 2023, and was heading for its lowest close since November 2023. First American chief economist Mark Fleming calculates that the half-point rise in rates since summer has cut a typical house hunter's buying power by about $19,000.

The Mortgage Bankers Association is already seeing the fallout in its application data, with volumes sliding again in the face of rising rates. "Affordability and borrower demand have weakened in recent weeks as the higher-rate environment continues to put pressure on both prospective homebuyers and homeowners looking to refinance," said MBA President and CEO Bob Broeksmit.

For South Bay buyers, the jump is the latest reminder that the 7% era is not a blip — rates are now a full percentage point above late February's 5.98% low, which works out to roughly $276 a month more on a $400,000 loan. The upside of the rate shock is thinner competition: rate-sensitive buyers are stepping back, sellers are conceding more (56% of LA-area sales included seller concessions in August), and negotiating on price, buydowns and terms has more room than it did a month ago.
