Wire transfers are processed by our partner bank 24/7, however wire transfers are only processed by the Federal Reserve on business days (Monday to Friday + Non Federal Bank Holidays) outside of 6:45 PM EST and 9 PM EST.
This means that on a normal business day, wire transfer processing will only be paused starting at 6:45 PM EST, and then once 9PM EST comes around, your wire transfer should arrive shortly.
This schedule starts on Sunday at 9PM EST and then repeats until it ends on Friday at 6:45 PM EST.
