Accounting entries and ledgers
Every payment ends as balanced ledger entries: customer accounts, nostros, and the suspense accounts that hold whatever cannot post cleanly.
IN ONE LINE
An everyday analogy: imagine every payment as a parcel that collects a signature at each handover — and then realise the signatures are the point.
The parcel is fiction; the signatures are real.
When you pay someone abroad, no money travels: instead, a chain of banks each writes a matched pair of entries in its own books — take from this account, give to that one — and the sum of all those pairs is the payment.
Accounting is not the paperwork after the payment; it is the payment.
And when an entry arrives that cannot be matched to anything — money with no explanation — it goes on a special shelf called a suspense account until someone works out whose it is.
The shelf must be emptied regularly; that is a rule, not a preference.
WHAT IT ACTUALLY IS
Every payment resolves into balanced double entries at each institution it touches.
An outgoing customer transfer, at its simplest: debit the customer's account, credit the account through which the bank settles — a nostro at a correspondent, or a settlement account at the central bank or CSM.
The receiving bank mirrors it: debit its nostro or settlement account, credit its customer.
A nostro account is 'our account at your bank'; the same account seen from the servicing side is a vostro.
Suspense accounts hold entries that cannot yet post finally — an incoming amount whose beneficiary reference fails, a return awaiting investigation.
Institutions design their charts of accounts differently, but the grammar is universal: every movement lands somewhere, and unexplained money parks in suspense, briefly.
HOW IT WORKS
The practitioner's discipline is knowing which event triggers which entries, and when.
Message and money move separately: an MT103 can arrive today for cover arriving tomorrow, so posting logic must decide what the customer sees in the gap.
Each hop in a correspondent chain posts across its own books only — no bank writes entries in another bank's ledger — and the end-of-day MT940 statement is how the account owner learns what its correspondent actually did, feeding reconciliation.
Value dates drive interest: post with the wrong value date and someone gains or loses a day of funds, which is why back-valuation exists as a repair.
Suspense hygiene is audited: entries carry aging limits, named owners, and escalation when they linger — a suspense account that only ever grows is a control failure in slow motion.
