Multi-currency accounts explained: IBAN, routing numbers, BSB and when to use each
A virtual account with real local details lets you get paid like a local in multiple countries. Here is what those details mean and when local rails beat a SWIFT wire.
A multi-currency account holds and moves money in several currencies from a single place. The feature that makes it genuinely useful, though, is local account details: real identifiers in each market that let you receive and send money as if you held a domestic account there. Understanding what those details are — and when to use local rails versus an international wire — turns a multi-currency account from a novelty into an operating advantage.
Virtual accounts with local details
A virtual account is a set of receiving details issued to you in a specific currency and market, backed by a licensed banking or payment partner. To the person paying you, it looks and behaves like a normal local bank account: they send to a familiar-looking identifier over their domestic rails, and the money arrives in your multi-currency balance. You can hold that currency, convert it when the rate suits you, or pay it out locally — without a foreign wire in sight.
IBAN, routing number, sort code, BSB — the same idea in different clothes
Different markets identify accounts differently, which is why the details you receive depend on the currency and country. The concept is always the same — a way to route money to the right institution and the right account — but the format and the accompanying rails differ.
- IBAN — the International Bank Account Number, used across the euro area and much of the wider region; pairs with SEPA for local euro transfers.
- Routing and account number — the United States format; pairs with ACH for domestic dollar transfers and FedWire for wires.
- Sort code and account number — the United Kingdom format; pairs with Faster Payments for near-instant local sterling transfers.
- BSB and account number — the Australian format; pairs with local Australian dollar rails.
- SWIFT/BIC — an international identifier used to route cross-border wires between banks when no local option exists.
Local rails versus SWIFT
When you hold local details in the destination currency, payments can move over that country's domestic rails — fast, low-cost and with the full amount arriving intact. A SWIFT wire, by contrast, routes internationally through the correspondent-banking network: it reaches almost anywhere, but it is slower, often more expensive, and intermediary banks may deduct fees along the way. The rule of thumb is simple: if you already hold the currency and the recipient is local to it, use local rails; reserve SWIFT for the cases nothing else reaches.
The power of a multi-currency account is not holding many currencies. It is being able to get paid, and pay, like a local in each of them.
When it earns its keep
Multi-currency accounts pay off whenever your money crosses borders repeatedly: businesses invoicing customers in several countries, freelancers with international clients, or anyone who would otherwise convert to their home currency and back again, losing a little on each leg. By receiving in the customer's currency, holding it, and converting on your own terms, you cut out needless conversions and keep control of both timing and cost.
