The Clearing House Comments on Nacha’s RFC on the Definition of Banking Day Date: October 23, 2026 Blurb: The Clearing House submitted a comment letter in response to Nacha’s Request for Comment on proposed revisions to the definition of “Banking Day.” The Clearing House supports the proposal, which would provide greater clarity, consistency, and predictability in the application of the Nacha Operating Rules and related ACH processing deadlines. The Clearing House also supports the proposed clarification regarding settlement when an ODFI or RDFI is closed on a Banking Day, noting that the proposed revisions align more closely with the existing EPN Operating Rules and operations.
