Mortgage rate-lock activity declined sharply in September as higher borrowing costs and a selloff in bonds weighed on lending pipelines, according to Mortgage Capital Trading’s October Lock Volume Indices.
Total rate-lock volume fell 10.15% from August, while purchase locks dropped 9.85%. Compared with September 2025, total locks were down 27.25% and purchase locks fell 11.86%. These figures measure MCT’s participating lender activity, not every U.S. mortgage application or funded loan.
Bond-market pressure reaches mortgage borrowers
MCT attributed the September pullback to a bond selloff and higher mortgage rates. The 10-year Treasury yield rose by more than half a percentage point during the month, according to the company’s analysis. Rising yields generally push mortgage funding costs higher and can discourage both refinancing and home purchases.
The Federal Reserve also raised its benchmark interest-rate target by a quarter percentage point in September. Mortgage rates do not move mechanically with the Fed’s policy rate, but expectations for inflation, Treasury yields and mortgage-backed securities pricing all influence the rates offered to borrowers.
What lenders should watch
Purchase lock volume is particularly important because it reflects demand from borrowers seeking to secure financing for home transactions. A monthly decline can signal a weaker near-term origination pipeline, although seasonal factors and changes in the lender sample also affect comparisons.
MCT’s report showed the downturn was not limited to one month: the 27.25% year-over-year drop in total volume points to a more substantial contraction compared with the same period in 2025. Its data should be read alongside Mortgage Bankers Association application figures, housing sales and lender earnings to assess the broader market.
For mortgage brokers, loan officers and lenders, the immediate implication is continued competition for a smaller pool of rate-sensitive borrowers. The next month’s lock-volume report will help establish whether September was an unusually steep decline or the start of a longer slowdown.
