Fedwire is the US Federal Reserve's real-time gross settlement rail for USD. SWIFT is the global messaging network for cross-border wires. They work together on most inbound USD payments. Track the SWIFT leg free by UETR on Ohmyfin →
Fedwire Funds Service is operated by the Federal Reserve Banks and has been the backbone of large-value US dollar settlement since 1918. It settles in central-bank money — not commercial bank money — which means there is zero credit risk between participants. Fedwire is irrevocable: once a payment is posted, it cannot be recalled unilaterally by the sender. The service runs from 21:00 ET the prior calendar day to 19:00 ET on the settlement day, giving a daily processing window of 22 hours.
SWIFT does not settle anything. SWIFT is a secure financial messaging network — it carries instructions between banks, but the actual movement of funds always happens inside a domestic settlement system. For USD, that is Fedwire (for large-value same-day wires) or CHIPS (Clearing House Interbank Payments System, for netting of large interbank flows). For EUR it is T2 (formerly TARGET2), for GBP it is CHAPS, for JPY it is BOJ-NET, and so on. SWIFT is the pipe; Fedwire is the vault.
How they work together on a typical cross-border USD payment: suppose a company in Germany wires USD to a supplier in New York. The German bank sends a SWIFT MT103 message (or pacs.008 under ISO 20022) with the payment details. That message travels through any correspondent banks in the chain. The last correspondent in the US receives the MT103, then funds the beneficiary's US bank account via Fedwire. The SWIFT message carries a UETR (Unique End-to-end Transaction Reference) that you can look up on Ohmyfin to see exactly where the payment is. Once the funds hit Fedwire, SWIFT's role is finished.
CHIPS vs Fedwire: large interbank USD flows often settle on CHIPS rather than Fedwire. CHIPS is operated by The Clearing House and uses a multilateral netting algorithm that reduces the gross value of funds actually moved. CHIPS settles $1.8 trillion per day on average. Most incoming international wires from correspondent banks ultimately flow through either CHIPS or Fedwire — from the beneficiary's perspective the result is the same: same-day USD credit.
Tracking differences: the SWIFT leg carries a 36-character UETR that works globally across every bank in the chain. The Fedwire leg is tracked by an IMAD (Input Message Accountability Data) and OMAD (Output Message Accountability Data) — a bank-specific reference assigned by the Federal Reserve. The IMAD/OMAD is only visible to the originating and receiving banks and cannot be looked up publicly. If your USD wire is delayed, Ohmyfin can tell you the latest SWIFT status; for the domestic US Fedwire leg you will need to contact your US bank.
Fedwire vs ACH: Fedwire is not ACH. ACH (Automated Clearing House) is the US batch-settlement system for low-value, reversible domestic payments like payroll and consumer bills. Fedwire is high-value, irrevocable, and real-time. For a $500k business payment, Fedwire is used — ACH has per-transaction limits and next-day settlement. For a $200 payroll payment, ACH is used. SWIFT is only relevant for the cross-border leg in either scenario.

No — Ohmyfin tracks SWIFT GPI payments via UETR. Fedwire-only intra-US wires (no SWIFT leg) are tracked by the originating or receiving bank using IMAD/OMAD references. Contact your US bank for those.
Almost all of them, yes. USD cross-border payments settle in the US via Fedwire or CHIPS. The cross-border messaging leg uses SWIFT; the final USD settlement uses Fedwire or CHIPS. There is no public cross-border USD rail that bypasses both.
Fedwire Funds runs from 21:00 ET the previous calendar day to 19:00 ET on the settlement day (22-hour window). Payments received by a US correspondent after 19:00 ET will settle on the next business day. SWIFT GPI payments that arrive in the US after the cut-off will be queued overnight.
In the US, "wire transfer" in common usage refers to a Fedwire-settled same-day USD payment, whether it originated domestically or arrived via SWIFT from abroad. Technically Fedwire, CHIPS, and SWIFT are all separate systems — but the customer-facing product at a US bank is usually called a "domestic wire" (Fedwire-only) or "international wire" (SWIFT + Fedwire).
CHIPS (Clearing House Interbank Payments System) is a private-sector USD multilateral netting system run by The Clearing House. It settles ~$1.8 trillion per day on average by netting flows between large banks. Fedwire is the Federal Reserve's RTGS that settles gross (no netting). Most international USD wires flow through CHIPS for the interbank leg; individual customer wires show up as Fedwire credits at the receiving bank.
No — Fedwire is US-domestic only. To send USD to a foreign bank account, your US bank will send a SWIFT MT103 or pacs.008 message to the foreign bank, using Fedwire only to debit your account and fund its own correspondent. The SWIFT GPI message is the cross-border layer.
