MT950 — Statement Message
Interbank account statement (nostro) issued by the correspondent bank to the nostro account holder. Strictly interbank counterpart of MT940 (corporate customer statement). Cornerstone of nostro/vostro reconciliation in bank treasury.
Purpose
MT950 sends to the nostro account-holding bank an exhaustive list of movements operated on D and the closing balance. Without MT950, the bank cannot reconcile its internal books (vostro) with the effective position at the correspondent. Differences = reconciliation "breaks", typical source of treasury incidents.
MT950 vs MT940 — the interbank nuance
- MT940 — Customer Statement Message: statement for corporate/institutional client. Includes rich descriptive fields (:86:) with labels, invoice references, BAI codes.
- MT950 — Statement Message: interbank statement. Stripped-down format, machine-optimized. No "Customer" concept — it's between two banks.
- A bank may send MT940 to its corporate client and MT950 to its correspondent in parallel for the same account. ISO 20022 camt.053 unifies both flows.

-}{5:{CHK:778899AABBDD}}Common pitfalls
- :60F: inconsistent with prior MT950: opening balance must be strictly equal to closing balance of previous statement. Otherwise reconciliation break.
- :61: with operation date ≠ value date: conflating them fails: liquidity impact depends on value date.
- Too much :86: free text: MT950 flows are machine-to-machine; verbose :86: breaks automatic parsers.
- Duplicated :28C: number: each statement must have a unique sequential number. Duplicates = forced re-reconciliation.
