On December 23, 2021, the CFPB adjusted the HMDA exemption threshold from $48 million to $50 million. The adjustment is based on the 4.7 percent increase in the average of the CPI-W for the 12-month period ending in November 2021 (up from 1.6 in 2019 and 1.3 in 2020). Therefore, banks, savings associations, and credit unions with assets of $50 million or less as of Dec. 31, 2021, are exempt from collecting data in 2022.
