Most international supplier wires settle in one to five business days, but the exact timing depends on correspondent banks, cut-off times, currency conversion, and compliance checks. Capture the payment’s UETR when you send it, then ask your bank for a SWIFT gpi trace if the transfer stalls.
Your bank can truthfully say the money left while your supplier can truthfully say nothing arrived. The missing information is usually sitting in the payment trail between those two statements.
You wired the deposit to your manufacturer on Monday. The confirmation says the payment was sent. By Thursday the factory says nothing has arrived, and the production slot you booked is starting to look negotiable.
Your bank says the money left. Your supplier says it never landed. Both are telling the truth, and the gap between those two statements is where a lot of operators lose a week they did not have.
Most international wires arrive within one to two business days. Some arrive the same day, occasionally within minutes. A minority take three to five business days.
A domestic wire is a much simpler object, which is why it usually clears the same day. An international wire has to cross more institutions, more time zones and more checks before anyone can call it delivered.
None of those reasons appear on the confirmation you were given, which is why a wire behaving completely normally looks identical to one that has gone wrong.
An international wire does not travel directly from your bank to your supplier’s bank. It moves through one or more correspondent banks, institutions that hold accounts with each other and pass the payment along the chain.
Each bank in that chain only reports on the leg it handled.
Your bank knows it sent the payment. It does not know what the correspondent in New York or Frankfurt did next, because it does not hold that record. Your supplier’s bank knows nothing has been credited, because from where it sits, nothing has. No single party has the full picture, which is why asking either end produces a confident answer that does not help you.
This is where most operators go wrong. They try to trace the payment using a reference that was never designed to travel with it.
Your bank’s internal reference identifies the instruction inside your bank and means nothing to the next institution. A Fedwire reference number, if the payment touched Fedwire, identifies one domestic leg. Your purchase order or invoice number identifies the commercial agreement, not the payment. None of these follow the money across the correspondent chain.
The reference that survives the whole journey is the UETR, short for Unique End-to-end Transaction Reference. SWIFT has required one on every customer credit transfer since 18 November 2018. It is 36 characters long, formatted like a UUID in five groups of eight, four, four, four and twelve characters, and it sits in field 121 of the MT103 message. It usually appears on the payment confirmation your bank already gave you, whether or not anybody pointed it out.
SWIFT compares it to the tracking number a courier issues for a parcel. Intermediary banks are required to pass the same reference along rather than generate a new one, which is exactly why it works from end to end. One UETR, one payment, from the moment it is sent to the moment it is credited.
Open the MT103 confirmation in your online banking and find the UETR in field 121. With that reference you can see what the banks handling the payment have reported about it, without any banking login and without involving your account. Independent trackers such as uetr.ai do this free of charge and require no account. This breakdown of how long an international wire transfer takes covers the timings and the tracking steps in more detail.
You will not have the MT103, because it belongs to the sender’s bank. Ask the sender for the UETR by name. It is a payment reference rather than a credential, so there is nothing sensitive about handing it over, and it is far more useful than the confirmation screenshot most senders send instead.
Tracking a wire returns a four-letter status code rather than a sentence. Four of them cover most of what you will see.
ACSP means accepted, settlement in process. The payment is moving and a bank in the chain currently holds it.
ACSC means accepted, settlement completed on the sending side.
ACCC means the funds have been credited to the beneficiary account. If your supplier still cannot see the money at this point, the conversation belongs with their bank, not yours.
RJCT means rejected. The payment is coming back, so you should be planning a resend rather than waiting.
Those codes decide what you do next, and just as importantly, what you tell your supplier. “It is at an intermediary bank in Frankfurt and moving” is a very different message from “it was rejected on Tuesday.”
Tracking tells you where a payment is. It cannot move it. Only the sending bank can act on the payment itself, and how you ask makes a real difference.
Call your bank and ask them to raise a SWIFT gpi trace, quoting the UETR. Then ask two specific questions: which correspondent bank is currently holding the payment, and what it is waiting for. Those are considerably harder to deflect than a general query about a late transfer, because answering them requires somebody to actually look the payment up.
Be clear about what nobody can do for you. No tracking service can release, recall, cancel or accelerate a payment. Any service that asks for your online banking password or a one-time passcode in order to track a transfer is asking for something no tracker needs, and you should close the tab.
The operators who stop losing days to this make one change. They capture the UETR at the moment the payment is sent and record it against the purchase order.
It takes a few seconds at the point of payment and removes the twenty minutes of digging that otherwise happens later, usually while a factory waits for an answer. If you run supplier payments through a shared inbox or an ops sheet, add a UETR column next to the PO number and make filling it a step in the payment checklist.
International wires will keep being slower and less transparent than the domestic payments you are used to. That is a function of how correspondent banking works, and it is not changing this quarter.
What has changed is that the information exists, attached to every payment, sitting on a confirmation already in your inbox. The difference between a lost week and a two-minute answer is almost always whether somebody wrote down the UETR at the time.
You should contact the sending bank for a trace when an international wire exceeds the arrival window your bank quoted, or immediately when a production deadline depends on confirmation. Many international wires settle within one to five business days, but weekends, cut-off times, currency conversion, intermediary banks, and reviews can extend that timeline. Do not wait passively if your supplier needs funds to reserve inventory or release goods. Provide the payment date, amount, currency, beneficiary details, bank reference, and UETR when you contact the bank.
A UETR is the Unique End-to-end Transaction Reference that identifies a SWIFT payment across the correspondent-banking chain. On an MT103 confirmation, it appears in field 121 and is typically a 36-character UUID-style reference in an 8-4-4-4-12 pattern. The UETR is more useful than an invoice number or local bank reference when a payment needs tracing because intermediary banks preserve it through the transaction route. Ask your sending bank to use the UETR for any SWIFT gpi trace.
Your supplier can provide the UETR to its bank and use it to support an investigation, but the sending bank is normally best positioned to initiate a formal SWIFT gpi trace. The supplier does not need access to your online banking or account credentials. Send the UETR, payment date, amount, currency, and payment confirmation through your established supplier contact. If the payment has reached ACCC status but the supplier cannot locate it, the supplier should ask its bank to investigate account crediting and internal reconciliation.
ACSP means Accepted Settlement In Process, which indicates that the payment has been accepted for execution and settlement is underway. It is commonly an in-transit status rather than proof that the beneficiary has received usable funds. If ACSP persists beyond the bank’s normal delivery window, ask the sending bank for a SWIFT gpi trace and the specific reason the payment has not progressed. Do not tell a supplier the payment has arrived until the beneficiary bank confirms account credit.
You should not resend a delayed supplier wire until your bank confirms whether the original payment is still moving, rejected, or returning. A second wire can create a duplicate-payment problem if the first payment eventually arrives. Ask the bank for the UETR-based trace result, current status, reason code, and expected return process before you make a replacement payment. If beneficiary information was wrong, independently verify the corrected bank details with your supplier before submitting a new instruction.
