Fedwire is the Federal Reserve's real-time gross settlement (RTGS) system used by US banks and financial institutions to transfer large sums of US dollars domestically. Each transfer settles individually and immediately — final and irrevocable — making Fedwire the backbone of high-value US dollar movement, including the correspondent banking leg of most international wire transfers.
Fedwire operates as a real-time gross settlement system, meaning each payment is processed individually and settled instantly rather than batched and netted at end of day. When a bank initiates a Fedwire transfer, the Federal Reserve debits the sending bank's reserve account and credits the receiving bank's reserve account in real time. The settlement is final and cannot be reversed. This is fundamentally different from ACH, which batches transactions and settles on a net basis hours later. Fedwire processes over $4 trillion in transfers on a typical business day.
When you send an international wire through your US bank, Fedwire is almost always involved in the domestic leg. Your bank moves dollars to a US correspondent bank via Fedwire before those funds are converted and routed onward to the recipient country. This means Fedwire is an invisible infrastructure layer behind most SWIFT transfers that originate in the US. The Fedwire leg itself settles in seconds, but the subsequent correspondent banking steps — often including foreign exchange conversion and routing through additional banks — are what cause the 2-5 day delay for international wires.
Fedwire and ACH (Automated Clearing House) are both operated or overseen by the Federal Reserve, but they serve different use cases. Fedwire is designed for large, time-critical, irrevocable transfers — minimum practical amounts are typically $10,000 or more, and banks charge $15-35 per transaction. ACH is designed for smaller, lower-urgency transfers like payroll and bill payments, settling in 1-3 business days at near-zero cost per transaction. Most retail bank wires and international transfers use Fedwire. Most direct deposits and automated bill payments use ACH.
Fedwire solves the domestic settlement problem well — it is fast, final, and reliable for moving dollars between US banks. The bottleneck for international payments is everything that happens after the Fedwire leg: currency conversion, correspondent bank routing, and foreign receiving bank processing. Digital asset rails like Stellar and Tron bypass this correspondent banking chain entirely. A sender converts USD to USDC on Coinbase, sends it cross-border in seconds on-chain, and the recipient converts locally via an exchange like CoinDCX or Bitso. All-in costs are typically 0.5-1.5% versus 3-8% for a full Fedwire-plus-SWIFT chain.
Fedwire is used for large-value, time-critical US dollar transfers between banks and financial institutions. Common uses include interbank settlements, corporate treasury transfers, real estate closings, and the domestic leg of international wire transfers. It is not typically used for everyday consumer payments.
Fedwire settles in real time — individual transactions are processed and finalized in seconds. Settlement is final and irrevocable. However, Fedwire only operates about 21 hours per day on business days, so transfers initiated after the cutoff time are processed the next business day.
The Federal Reserve charges banks a small per-transaction fee (fractions of a cent to a few dollars). Banks pass this through to customers as a domestic wire fee, typically $15-35 for outgoing transfers. International wires add additional costs for SWIFT messaging, intermediary banks, and FX conversion.
Not exactly. A bank wire transfer is the product your bank offers you. Fedwire is the underlying infrastructure the bank uses to move funds between reserve accounts at the Federal Reserve. Your bank wire typically rides on Fedwire domestically, then connects to SWIFT for international delivery.
No. Fedwire only moves US dollars between US-based banks and financial institutions. It handles the domestic settlement leg of an international transfer, but the cross-border portion requires a separate system — typically SWIFT — to route funds to a foreign bank. You access this indirectly through your bank's international wire service.
For international transfers, digital asset rails skip the Fedwire-plus-SWIFT correspondent chain entirely. Using USDC on Stellar or Tron, a sender on Coinbase or Kraken can reach recipients via exchanges like CoinDCX, Luno, or Bitso with all-in costs often under 1%. Wise also offers better rates than traditional bank wires for most corridors. RemitRoutes compares both options live for your specific send and receive currencies.
