End of day processing guidance around Same Day ACH funds availability requirements for Receiving Depository Financial Institutions (RDFIs).


RDFIs - End of Processing Day Guidance

During Phases 1 and 2 of Same-Day ACH (September 23, 2016 through March 15, 2018), an RDFI is required to make funds available from a Same-Day ACH credit in its customer’s account no later than the end of processing of transactions for that settlement date. While funds do not need to be available for cash withdrawal at that time (e.g., via an ATM), they must be available to satisfy other subsequent debit entries against the account (e.g., to pay ACH debits and checks).

For example, if an RDFI finishes processing all credits and debits to its DDAs for the settlement date of Thursday, November 5, 2015 by 11:00 p.m. on November 5, then the funds from a SameDay ACH credit must be available in the Receiver’s account by 11:00 p.m. on November 5 and must be available to satisfy subsequent debits (other than cash withdrawals) to the Receiver’s account.

The Same-Day ACH availability requirement is a “no later than” deadline; RDFIs always have discretion to make funds available earlier. This includes flexibility to make decisions regarding availability based on the specific processing window during which Same-Day ACH transactions are received, or even on an account-by-account or transaction-specific basis, all within the individual RDFI’s risk management framework. Similarly, RDFIs are not required to make funds available for withdrawal (such as from an ATM or teller window) in the end-of-day processing cycle as part of Phases 1 and 2, but they may choose to do so in their own discretion, including on an account-by-account or transaction-specific basis.
