Mortgage lenders broadened their available loan programs modestly in October, ending two consecutive months of tightening, but the improvement was concentrated in conventional and jumbo products rather than across the entire borrower market.
The Mortgage Bankers Association’s November 10, 2026, Mortgage Credit Availability Index report, calculated using ICE Mortgage Technology data, showed the overall index increasing 0.4% to 107.5. Higher readings generally indicate more available mortgage credit, but the measure is based on lenders’ program terms and eligibility criteria, not an observed increase in loan approvals.
Conventional and jumbo lending drive the increase
The Conventional MCAI rose 0.6%, compared with a 0.1% gain in the Government MCAI, which covers FHA, VA and USDA programs. Within conventional lending, the Jumbo MCAI increased 0.8%, while the Conforming MCAI was unchanged. The divergence matters: borrowers seeking loans above conforming limits may have seen more program choices, while buyers relying on government-backed financing experienced little measurable change.
MBA Deputy Chief Economist Joel Kan attributed part of the increase to additional adjustable-rate mortgage offerings for borrowers with lower loan-to-value ratios, including certain cash-out refinance programs. The association said the jumbo index reached its highest level in three months. These developments point toward competition for borrowers with substantial equity rather than a broad easing for households with limited savings or weaker credit.
What the index does—and does not—tell borrowers
MBA’s index is benchmarked to 100 in March 2012 and combines underwriting and program criteria across more than 95 lenders and investors. The association cautions that movements in the index reflect the availability of credit products. A 0.4% increase does not mean mortgage approval rates rose by 0.4 percentage points, nor does it establish that mortgage costs fell.
The timing also matters. The underlying data cover October and were released November 10. This is a catch-up report on that release, not a new November 11 index reading. The modest change follows two months of declines, so it would be premature to characterize one month as a sustained loosening cycle.
Implications for originators and housing demand
For mortgage originators, expanded ARM and jumbo menus may create refinancing or purchase options for well-qualified households. For policymakers concerned about access to ownership, the nearly flat government and conforming readings suggest that the improvement is not evenly distributed. Credit availability remains only one constraint alongside interest rates, household income, down payments, inventory and insurance costs.
The next monthly release will indicate whether October’s increase was an isolated adjustment or the start of a more durable shift in underwriting offerings. Until then, the appropriate conclusion is narrow: mortgage credit supply edged higher, with most of the movement in conventional lending.

MBA reported November 10 that mortgage credit availability rose 0.4% in October to an index reading of 107.5, ending two months of declines. Conventional and jumbo offerings drove the increase, while government-backed and conforming credit changed little. The report measures program availability, not approval rates.
