MT191 / MT291 ↔ camt.106

1 pair on this page · Use case: Charges/interest

Direct message-level match

Business purpose

Request for Payment of Charges, Interest and Other Expenses — a financial institution requests reimbursement of charges, interest, or other expenses (previously unknown to the receiver) arising from handling a prior transaction. MT191 is the category-1 (customer/FI-facing) variant, MT291 the category-2 (FI-to-FI) variant; both carry an identical official name and differ only in SWIFT message category.

What does NOT map cleanly

Swift lists MT191/MT291 against camt.106 (Charges Payment Request), distinct from MT190/MT290 against camt.105 (Charges Payment Notification). This is a message-purpose mapping, not proof that every field or bilateral charge workflow maps directly. For reconciliation, keep the request and any subsequent charge settlement separate: a request for reimbursement does not by itself prove that the requested amount was paid.

Migration notes

Swift's September 2026 roadmap shows a Standards Release 2028 planning aim for charge messages and says enforcement depends on adoption. The same document warns that roadmap dates are under review after the SR2026 deferral. Do not treat the aim as a confirmed universal retirement deadline for MT191/MT291.
