On December 31, 2018, the CFPB adjusted the HMDA exemption threshold from $45 million to $46 million. The adjustment is based on the 2.6 percent increase in the average of the CPI-W for the 12-month period ending in November 2018. Therefore, banks, savings associations, and credit unions with assets of $46 million or less as of Dec. 31, 2018, are exempt from collecting data in 2019.
