What it means
Banks cannot open branches in every country they trade with, so they form correspondent relationships instead. A domestic bank agrees to hold funds and process payments for a foreign bank, and the account it opens for that foreign partner is the vostro account.
The foreign bank, looking at the same account in its own records, calls it a nostro account. The distinction is purely about perspective, not about a different product.
If a bank in Singapore holds dollars with a New York bank, the New York bank calls that balance a vostro account and the Singapore bank calls it a nostro account. Both entries describe one pot of money sitting in New York.
This arrangement matters commercially because it is how cross-border trade actually settles. When an importer pays a foreign supplier, the money rarely travels physically; instead, balances are debited and credited across correspondent accounts until both banks agree the transfer has happened.
Vostro accounts carry real risk for the bank that hosts them, which is why they attract heavy compliance attention. The host bank is effectively giving a foreign institution access to its payment system, so it must satisfy itself that the correspondent screens its own customers properly for money laundering and sanctions breaches.
For business readers, the practical consequence is cost and speed. Payments that pass through two or three correspondent banks pick up fees at each hop and can take several days, which is why treasury teams push to shorten payment chains or route through banks with direct relationships.
In practice
Real-world examples.
Example
A mid sized Kenyan bank wants to settle dollar payments for its coffee exporters without holding a US banking licence. It opens a relationship with a large American bank, which sets up a vostro account holding the Kenyan bank's dollar balances and processes payments on instruction.
Example
A European bank reviews its correspondent network and finds it holds vostro accounts for eleven small foreign banks, three of which generate almost no revenue. Because each relationship carries compliance monitoring costs, the bank closes those three accounts, a decision the industry calls de-risking.
Example
A UK manufacturer complains that a $200,000 payment to a Vietnamese supplier arrived four days late and $85 short. Its bank traces the payment through two intermediary correspondents, each of which deducted a fee from the vostro settlement before passing the balance on.
Think of it
“Vostro is their account at our bank-their money held by us in our currency.
Formula
Calculation
Closing vostro balance = opening balance + inbound credits - outbound debits - charges
Banco Andino, a fictional South American bank, holds a dollar vostro account with a New York correspondent. The account opens the month at $2,400,000. During the month, Banco Andino's customers receive $850,000 of inbound export payments and send $1,150,000 of outbound import payments, and the correspondent charges $1,200 in transaction and maintenance fees.
Closing balance = $2,400,000 + $850,000 - $1,150,000 - $1,200 = $2,098,800. Banco Andino records the same $2,098,800 in its own books as a nostro asset, and any difference between the two figures is a reconciliation break that the treasury team must clear before month end.Case study
Seen in the real world.
The following is an illustrative and entirely fictional example. Meridian Trade Bank, an invented regional lender, built its export business on a single dollar vostro relationship with one large overseas correspondent. Because it had never negotiated the fee schedule, it was paying a flat $28 per payment plus a monthly maintenance charge, and its customers were routinely seeing deductions applied by a second intermediary bank in the chain.
When Meridian's fictional treasury team mapped the actual route of 500 payments, it discovered that roughly two thirds were reaching a destination bank that its correspondent could reach directly, while a third were being passed through an extra hop. It renegotiated the arrangement, agreed a tiered fee of $18 per payment above 400 payments a month, and asked the correspondent to route the remaining third differently.
The result was a saving of about $6,000 a month in fees and, more importantly, an average settlement time that fell from three days to one. Meridian used the improvement as a selling point when pitching for new exporter clients.
Watch out
Common mistakes.
- Treating vostro and nostro as two different types of account rather than two views of the same balance, which leads to double counting in group reporting.
- Assuming the host bank has no responsibility for who ultimately sends the money, when in fact regulators expect it to understand the correspondent's own customer base.
- Budgeting only for the first bank's stated fee and ignoring deductions taken by intermediary banks further along the payment chain.
Questions
People also ask.
Who owns the money in a vostro account?
The foreign correspondent bank owns it; the host bank simply holds and administers it, recording it as a liability on its own balance sheet.
Does a normal business ever open a vostro account?
No, these are interbank arrangements; a company's own foreign currency account is just an ordinary bank account, even if the bank settles it through a vostro relationship.
Why do banks close vostro relationships they already have?
Compliance monitoring costs money, and if a correspondent generates little revenue relative to the sanctions and money laundering risk it brings, the host bank often decides the relationship is not worth keeping.
