Total cost has several layers
| Cost layer | What to inspect |
|---|---|
| Outgoing wire fee | Charged by sending bank |
| FX spread | Difference between market rate and customer conversion rate |
| Correspondent/intermediary fees | May be deducted in transit |
| Receiving-bank fee | May be charged to beneficiary |
Routing data must be exact
International instructions may require SWIFT/BIC, IBAN, local clearing code, beneficiary address and purpose-of-payment information. Requirements vary by destination.
FX can matter more than the wire fee
On a large conversion, a small change in exchange rate can cost more than the bank's visible transfer fee. Compare the delivered amount, not only the send fee.
Timing is less predictable
Time zones, compliance screening, intermediary banks and local holidays can extend delivery. Build extra time into supplier or acquisition deadlines.
Controls should be stricter
Use approved beneficiary templates, independent verification for changed instructions and limits appropriate to the company's normal payment size.
Primary sources and reference material
Match the payment rail to the operating need.
Cost, speed, finality, fraud controls, reconciliation and staff permissions all matter. The best treasury setup is the one that fits the business process—not the one with the most features.
