IBANs, BIC codes, nostro accounts and virtual accounts — the account infrastructure behind international business banking.
Quick answer
International banking runs on standardised identifiers (IBAN for accounts, BIC for institutions) and inter-bank account structures (nostro/vostro). Virtual and multi-currency accounts sit on top of this infrastructure, letting one business hold and receive multiple currencies without opening accounts in each country.
