Rising Treasury yields and stubborn inflation are pushing borrowing costs to levels not seen since late 2023
The window that briefly cracked open for U.S. homebuyers earlier this year has all but closed again, and the latest data from Freddie Mac suggests it is not reopening anytime soon.
The 30-year fixed-rate mortgage climbed to 7.28% in the week ending October 1, its highest level in nearly three years, as surging Treasury yields and persistent inflation continued to squeeze American homebuyers.
The benchmark rate rose from 7.03% the prior week, extending a six-week streak of consecutive increases. It now sits nearly a full percentage point above the 6.34% recorded a year ago and within a single basis point of the November 22, 2023 peak of 7.29%.
The 15-year fixed-rate mortgage, widely used by borrowers refinancing a home loan, also rose to 6.60% from 6.42% last week, up from 5.55% a year ago.
Bond market turbulence pushes rates higher
The primary catalyst behind the rate surge is a sharp climb in the 10-year US Treasury yield, the benchmark most lenders use to price home loans. It reached 5.34% early Thursday, up from 3.97% in late February.
Over the three months ending Wednesday, the 10-year yield posted its largest quarterly jump since 1994, driven largely by inflation expectations tied to surging energy costs.
The Federal Reserve's preferred inflation gauge, the Personal Consumption Expenditures (PCE) index, rose 3.4% on a year-over-year basis. It's below the 3.7% forecast, but offering little reassurance to those watching the underlying trend.
KPMG chief economist Diane Swonk put it plainly: "Cooler on paper, hot underneath. The measuring stick moved. The inflation problem did not."
Minneapolis Federal Reserve President Neel Kashkari held to his hawkish line, telling a Council on Foreign Relations event in New York that a cooler-than-expected August inflation reading had done little to alter his thinking on the rate path ahead.
"It's been elevated now for more than five years. I didn't think the inflation data today really changed that story for me very much," he said.
Market pricing currently implies approximately a 60% probability of a further Federal Reserve rate hike at its December meeting.
David Russell of TradeStation says a softer-than-expected core PCE reading supports the case against an October rate hike, though recent data revisions make it difficult to assess how much of the slowdown reflects genuine disinflation.https://t.co/zAz3k1sW7M

Affordability tightens for buyers and brokers
The cost of the rate climb is concrete. At 7.28%, a borrower financing a $400,000 home loan now pays roughly $276 more per month than someone who locked in near late February's brief dip to 5.98%.
The impact is feeding directly into buyer hesitation and subdued broker deal volumes.
The National Association of Realtors (NAR) reported that existing-home sales fell 2% in August from July to a seasonally adjusted annual rate of 3.98 million units, their slowest pace in more than a year.
High mortgage rates have kept the US housing market under pressure throughout 2026, and with Treasury yields at multi-year highs, a quick reversal appears unlikely.
Economists at PNC wrote that affordability concerns "extend beyond the government's inflation measures," adding: "There may be some relief coming on affordability, but in the near term the cost of living will continue to stress households."
