MT103 confirmation doesn’t prove beneficiary received funds

An MT103 is a standardized SWIFT message that records a sending bank’s instruction and the route a cross-border payment took. Financial institutions and corporate treasuries commonly use copies of MT103 to show that a payment was initiated and processed through correspondent banks. The message, however, is a record of the instruction and the path, not a receipt from the beneficiary’s account.

An MT103 includes sender and beneficiary details, amounts, value dates and bank identifiers. It can show when and how a payment moved through intermediaries, but it cannot show whether the beneficiary bank posted the amount to the recipient’s ledger, routed the funds to another account, or returned the payment.

Intermediary banks can affect final credit. Correspondent banks that maintain nostro and vostro accounts may apply fees that reduce the net amount credited. Currency conversions by intermediaries can change the received amount. Errors in account numbers or name mismatches can cause returns. Compliance checks for anti-money laundering or sanctions, and technical or operational holds, can delay or reverse a payment after an MT103 has been generated.

When a sender needs proof that funds arrived, the most reliable documents are a credit advice or a bank statement from the beneficiary’s bank showing the amount posted to the beneficiary account. Some banks can issue MT910 or other confirmation messages that indicate a credit posting, but those messages are not used by all banks and depend on the institutions’ messaging arrangements.

‘An MT103 proves the payment instruction existed and was transmitted, but it does not prove the beneficiary’s account was credited,’ payments industry compliance advisers noted. They recommend requesting direct confirmation from the beneficiary’s bank for high-value or time-sensitive transfers, verifying account numbers and IBANs before sending, and monitoring transaction references for any returns or charges.

Banks can trace the message flow in disputes and explain returns or rejections, but tracing can take time and may require formal tracing requests or legal assistance. For accounting and legal purposes, an entry on the beneficiary’s bank statement or a formal credit advice from that bank is treated as the decisive evidence that funds were received.
