MT103: the customer credit transfer

IN ONE LINE

An everyday analogy: an MT103 is the banking world's version of a fully filled-in international money transfer form.

One form, one payment, one customer being paid.

The form has a box for who is sending the money, a box for who should receive it, a box for the amount and the day it is due, and a box answering the awkward question every international delivery raises: who pays the shipping? The form itself is not the money — it is the instruction that makes banks move the money across the accounts they keep with each other.

When something goes wrong weeks later, investigators pull out this form first, because every detail of the payment was fixed the moment it was written.

WHAT IT ACTUALLY IS

The MT103 is the single customer credit transfer: the MT message one bank sends another to execute one customer payment.

It names the ordering customer (the payer) and the beneficiary, and carries the value date, currency, and settlement amount, the payment reference, and a charge option that decides who bears the banks' fees — the sender, the beneficiary, or both sides sharing.

The MT103 travels between banks; the customer never sees it directly.

Depending on routing, the same MT103 may pass through one or more intermediary banks (serial routing) or go straight to the beneficiary's bank while the money moves separately (cover routing).

At each hop, the banks involved settle across the correspondent accounts they hold with one another.

HOW IT WORKS

Operationally, the MT103 is where most cross-border investigation work starts.

Field 20, the sender's reference, is the handle a case is opened under, and every later message about the payment should quote it.

The charge option matters commercially: OUR means the sender pays the charges, SHA splits them, BEN lets them be deducted from the beneficiary's amount — a frequent cause of "short payment" complaints.

Beneficiary details that fail validation at the receiving bank trigger repairs or returns, and how a return travels back varies by market and bilateral practice.

Names, addresses, and free-text fields are exactly what sanctions screening engines parse, so a poorly structured ordering-customer field can put an otherwise clean payment into a review queue.

Cut-off times at each bank decide whether the stated value date can actually be met.
