The average 30-year fixed mortgage rate climbed to its highest level in nearly three years last week. According to the Mortgage Bankers Association, the average contract rate on conforming 30-year loans rose 19 basis points to 7.49% in the week ended October 2, versus 7.30% the prior week — a level last seen in November 2023. Freddie Mac's separate survey, reported by Beinsure, put the average at 7.4%, up from 7.28% a week earlier and well above the 6.3% rate a year ago. The Mortgage News Daily daily survey cited by Beinsure even showed lenders offering 7.56%, near the highest borrowing costs since 2003. Higher rates are adding to affordability pressures for homebuyers and have sharply reduced refinancing activity.

The jump is striking because it reverses an earlier improvement in borrowing conditions. Beinsure reports that mortgage rates had fallen below 6% in February, shortly before the war in Iran began, raising expectations that housing affordability could finally improve. Since joint US-Israeli strikes against Iran began in late February, Prop News Time reports mortgage borrowing costs have risen about 1.4 percentage points, broadly tracking the 10-year Treasury yield, which moved above 5.3% and recently reached its highest level in 24 years on inflation concerns from higher oil prices and stronger-than-expected US economic growth. Inflation tracked by the Federal Reserve rose to 3.4% in August, well above the central bank's 2% target, keeping rate-cut hopes at bay.

Mortgage demand is visibly cracking under the weight of higher rates. The Mortgage Bankers Association's seasonally adjusted index showed total applications fell 4.2% week-on-week to their lowest level since February 2025, and Prop News Time notes volumes have fallen nearly 50% since January. Refinance applications dropped 8% for the week and 56% year over year, with purchase applications 15% below their year-earlier level. "Very few homeowners have an incentive to refinance at these rates," MBA economist Joel Kan said, per Beinsure, which also reports FHA purchase applications fell the most, down 6%. Borrowers are increasingly turning to adjustable-rate mortgages, which held a 10.3% share of applications versus under 3% in the early pandemic.

The rate surge lands on a housing market already strained by elevated prices — the Federal Housing Finance Agency reported nationwide home prices up 2.6% in July year over year, per Beinsure. Prop News Time reports the Federal Reserve raised rates in September and policymakers have signaled another hike could come before year-end, though markets currently price no change at the Fed's upcoming meeting. Politically, the pressure arrives ahead of the November 3 elections, with President Trump criticizing Fed board members while praising Chairman Kevin Warsh. Treasury Secretary Scott Bessent attributed inflation and mortgage-rate pressure partly to temporary oil-price spikes, arguing rates could ease once the Iran conflict ends. Unless inflation and Treasury yields relent, borrowing costs above 7% are likely to keep constraining housing demand.
