Mortgage Credit Availability Index
Complimentary for MBA Members! The Mortgage Credit Availability Index (MCAI) is a barometer on the availability or supply of mortgage credit at a point in time, using criteria from institutional investors who purchase loans through the broker and/or correspondent channels. The MCAI is calculated using several factors related to borrower eligibility (credit score, loan type, loan-to-value ratio, etc.) using data made available by ICE Mortgage Technology. These metrics and the underwriting criteria for numerous lenders/investors are analyzed and, through a proprietary formula, MBA calculates the MCAI which include indices for Total, Conventional, Government, Conforming and Jumbo segments. The base period and values for the total index is March 31, 2012=100; Conventional March 31, 2012=73.5; Government March 31, 2012=183.5.

Mortgage Credit Availability Increased in January
“Credit availability increased to start 2025, driven by conventional credit supply rising to its highest level since June 2022,” said Joel Kan, MBA’s Vice President and Deputy Chief Economist. “There were expanded loan offerings for cash-out refinances, along with more jumbo and non-QM loan programs. Although similar to last month, these were limited to borrowers with better credit. All other subindexes saw increases in January, a positive development for the spring homebuying season, if these trends continue.”
The MCAI rose by 2.5 percent to 99.0 in January. The Conventional MCAI increased 3.8 percent, while the Government MCAI increased by 1.0 percent. Of the component indices of the Conventional MCAI, the Jumbo MCAI increased by 5.3 percent, and the Conforming MCAI rose by 0.5 percent.
The Total MCAI has an expanded historical series that gives perspective on credit availability going back approximately 10-years (expanded historical series does not include Conventional, Government, Conforming, or Jumbo MCAI). The expanded historical series covers 2004 through 2010 and was created to provide historical context to the current series by showing how credit availability has changed over the last 10 years – including the housing crisis and ensuing recession. Data prior to March 31, 2011 was generated using less frequent and less complete data measured at 6-month intervals and interpolated in the months between for charting purposes. Methodology on the expanded historical series from 2004 to 2010 has not been updated.
