RELATED CONCEPT
Vostro Account
A vostro account is an account that a servicing financial institution maintains on behalf of a foreign correspondent bank in the domestic currency.
FINANCIAL INFRASTRUCTURE CONCEPT
Nostro Account
A nostro account is a bank account held by a domestic financial institution at a foreign correspondent bank in the currency of that foreign country.
Architectural context & analysis
Expressed from the account-owning institution perspective (literally 'our money held by you'), it enables cross-border trade, foreign currency clearing, and bilateral settlement.
Internal accounting ledgers must continuously reconcile expected nostro balances against external bank statements (MT940/camt.053) to catch value-date discrepancies and unconfirmed debits.
Worked operational scenario
A London bank holds a EUR account at a Frankfurt clearing institution to settle euro-denominated obligations arising from corporate customer trades.
Implementation considerations & controls
Treasury operations must model cutoff windows, intraday overdraft thresholds, and pending payment reservations independently for each active currency corridor.
