"This commentary is based on new data released by the FRPS in March, detailing payments activity by the 100 largest DIs by transaction account deposit size. The release provides the number and value of check, ACH, wire, and alternative payments (bank bill pay and person-to-person) at the 100 largest DIs and all other DIs for 2015, 2018, and 2021. The average business transaction account balances at the Top 100 DIs by deposit size imply that these DIs serve the largest businesses in the US. This flows through to payments."
