Correspondent banking, nostro & vostro
How banks pay across borders with no shared system: accounts held at each other, chains of correspondents, and what nostro and vostro mean.
IN ONE LINE
There is no world central bank where every bank holds an account, so banks in different countries need another way to pay each other.
The solution is old and simple: they open accounts with each other.
This arrangement is called correspondent banking.
Analogy: a trusted friend abroad.
You leave money with a friend in another city; when you need to pay someone there, you message your friend, who hands over local cash from your stash.
Banks do exactly this.
The account my bank holds at your bank is, from my side, a 'nostro' — banking Latin for 'ours'.
The same account seen from your bank's side is a 'vostro' — 'yours'.
Long chains of such relationships let a payment cross the world without any single shared system, one trusted hop at a time.
WHAT IT ACTUALLY IS
Correspondent banking is one bank providing accounts and payment services to another.
The bank holding the account is the correspondent; the bank owning the money is the respondent.
A nostro account is 'our account on your books' — Bank Alfa's euro account held at Nordbank is Alfa's nostro.
The identical account viewed from Nordbank's side is a vostro: someone else's money that Nordbank holds and services.
Payments move along these relationships: to pay in a currency it cannot settle directly, a bank debits or credits its nostro with a correspondent that can.
When the sending and receiving banks share no relationship, one or more intermediary agents bridge the gap, each hop settling across an account pair somewhere in the chain.
HOW IT WORKS
Operationally, correspondent banking is account management at a distance.
Treasury keeps each nostro funded — enough to cover the day's payments, not so much that idle balances cost money.
Ops works to the correspondent's cut-off times, not just its own, and watches for fees deducted along the chain that make the delivered amount smaller than the sent one.
Every statement from a correspondent must be reconciled against what the bank believes happened — unmatched entries become investigations.
The model is also under structural pressure: banks have reduced correspondent relationships over cost and financial-crime risk, so remaining chains can be longer and alternatives fewer, particularly in smaller currency corridors.
Institutions vary a great deal here.
THE WORDS
- Correspondent banking
- One bank providing payment and account services to another, so banks can reach currencies and countries where they have no presence.
- Nostro account
- 'Our account with you' — an account a bank holds at another bank, usually in that bank's home currency, to make and receive payments there.
- Vostro account
- 'Your account with us' — the same correspondent account seen from the servicing bank's side: an account it holds for a foreign bank.
- Intermediary agent
- A bank between the debtor agent and creditor agent that passes the payment along when the two have no direct relationship.
