The Clearing House (TCH) submitted a letter to NACHA regarding the proposal to expand Same Day ACH, and a related request for information regarding weekend and holiday ACH processing. Among other things, the letter stated that (i) in its role as an ACH Operator, TCH is prepared to implement the necessary changes to support a third Same Day ACH window if it is approved through the NACHA rulemaking process; but that (ii) TCH does not support any approach for either a third Same Day ACH window or weekend and holiday ACH processing that would create unnecessary credit and settlement risk for financial institutions.
