The Fedwire Funds Service is a United States real-time gross settlement service operated by the Federal Reserve Banks. Participating institutions use it for time-critical, high-value US-dollar transfers that are immediate, final and irrevocable once processed.

Most businesses access Fedwire through a bank. The bank controls customer eligibility, submission cut-offs, required beneficiary information and fees even though settlement occurs over the Federal Reserve service.

What a wire instruction should establish

  1. Confirm the beneficiary bank's routing information and the recipient's account details independently.
  2. Include the commercial purpose and invoice reference required by the bank and recipient.
  3. Require an appropriate approval level before release because completed Fedwire transfers are not ordinary reversible card transactions.
