On September 23, 2015, the US Federal Reserve Board approved enhancements to its automated clearing house service that will require its receiving depository institutions to process same-day payments. Morning settlements will now be cleared by 1pm, and afternoon settlements by 5pm, according to the approved plan. Originating banks will be required to pay a 5.2 cent interbank fee to receiving banks for each same-day electronic payment. The enhancements become effective September 23, 2016.
