The Mortgage Bankers Association's (MBA's) Mortgage Credit Availability Index (MCAI), a measure of access to mortgage credit, partially rebounded from an unusually large downturn in December. The Index rose 2.3 percent in January to 179.0. A lower MCAI indicates that lending standards are tightening while increases means credit is loosening. The MCAI fell 7.3 percent the prior month, driven by a 14.5 percent decline in the Conventional MCAI. The Conventional MCAI increased 4.9 percent while the Government MCAI was unchanged. Of the component indices of the Conventional MCAI, the Conforming MCAI increased by 7.3 percent, and the Jumbo MCAI increased by 3.0 percent.
