Typically, local payments in the NGN run on NIP (NIBSS Instant Payments).
NIBSS Instant Payments (NIP) is an account-number-based, online-real-time Inter-Bank payment solution.
Unlike SWIFT most transactions completed via Fedwire should be completed on the same day.
You should not need to instruct the sending bank specifically to use Fedwire. However, if asked how to send a payment to your USD account then you should instruct them to use Fedwire.
