US Q4 MBA Purchase Index Rebounds to 134.1, Falling Mortgage Rates Bring Brief Respite
According to the latest data provided by DataTrack, the US Q4 MBA Purchase Index (observation date October 23, 2026) reported at 134.1, a significant rebound from 129.2 in the previous reading (October 16). This crucial indicator measuring home purchase application demand in the housing market rebounded for the first time after bottoming out in recent weeks, indicating that as the pressure of funding costs slightly eased, market buying sentiment showed signs of a minor recovery. Despite this, the current index level remains far below the historical average, reflecting that the overall housing market is still in a relatively long-term trough.
Looking at the key breakdown, according to supplementary data from web searches, the main reason driving this index rebound is the drop in the 30-year fixed mortgage rate to 7.37%, hitting a near three-week low. Furthermore, to lower initial monthly payments in the current high-interest-rate environment, an increasing number of homebuyers are choosing adjustable-rate mortgages (ARM). The latest data shows that the share of ARMs in total mortgage applications has climbed to 11.3%, reaching a high over the past year or more, highlighting that the public is actively seeking flexibility in capital deployment to successfully purchase homes.
Regarding the rebound in this data, Mortgage Bankers Association (MBA) Vice President and Chief Economist Joel Kan pointed out that the continuous two-week drop in mortgage rates has indeed brought long-awaited breathing room for some borrowers, thereby boosting application volumes primarily driven by conventional mortgages. However, he also warned that current mortgage rates are still more than one percentage point higher than the same period last year, and the "lock-in effect"—where most existing homeowners hold mortgage rates far below current levels—remains. This has led many potential buyers to put their home-buying plans on hold, with overall purchase demand still lagging significantly by nearly 18% compared to the same period last year.
Looking ahead, in the short term (1-2 months), if US Treasury yields can continue to retreat from recent highs, driving mortgage rates steadily lower, it is expected that deferred home-buying demand may be released to some extent, bringing more bargain-hunting buying sentiment. However, in the medium term (3-6 months), the greatest risk to a comprehensive housing market recovery remains inflation stickiness and the pace of the Federal Reserve's (Fed) monetary policy. If the Fed delays the timeline for easing policy, causing mortgage rates to spike upward again, it will not only stifle the newly budding buying sentiment but could also trigger a further contraction in housing market transaction volumes.
