Blocked or rejected international bank transfer: the most common causes

A rejected transfer is almost never random

An international transfer can be blocked, delayed, or rejected for several well-identified reasons, almost always linked to incorrect information, a regulatory check, or a technical limit on the bank's side. Understanding which one applies to your case often allows the issue to be resolved in a few exchanges, rather than remaining in limbo for days.

Incorrect beneficiary details

This is by far the most frequent cause: a mistyped IBAN, an incorrect SWIFT/BIC code, or a beneficiary name that does not match the one registered on the account exactly. Some banks automatically reject the transfer as soon as a consistency check fails, without always specifying which one. Before resending the funds, verify these three details one by one with your supplier, ideally by requesting a recent bank statement or proof of bank details rather than an old document.

Compliance and anti-money laundering checks

Banks and payment intermediaries are legally required to screen every transaction against international sanctions lists and anti-money laundering rules. A sensitive destination country, an unusual amount compared to your typical activity, or a name that resembles that of a sanctioned person or entity can trigger a manual review. This is not an accusation: it is a routine check that can add one to three business days, sometimes requiring supporting documentation (invoice, commercial contract).

Delays linked to correspondent banks

An international transfer rarely travels directly from bank to bank: it often passes through one or more correspondent banks, each carrying out its own checks before passing the funds to the next. A simple public holiday in an intermediary country, a time difference, or an occasional technical outage can suspend the transaction for several hours without any error having occurred. This is also why the timeframe quoted by your bank ("1 to 3 business days") is an estimate, not a guarantee.

Practical steps to take when a transfer is blocked

• Contact your bank or payment intermediary and provide the transfer reference: ask explicitly whether it is a definitive rejection or simply an ongoing check

• Check and confirm the beneficiary's bank details in writing before attempting a new transfer, rather than resending the funds with the identical details

• If supporting documentation is requested (invoice, contract), provide it promptly and clearly: this is often the only step holding up the release of the hold

FAQ: blocked or rejected international transfers

How long can a compliance check take? Usually one to three business days, but it can be faster if you provide the requested supporting documents straight away.

Does a rejected transfer incur fees? That depends on your bank: some charge rejection fees, whilst others do not if the error was not your fault. Check your provider's fee schedule before resending the funds.
