FX underpins everything from international trade and ecommerceeCommerce ecommerce Commercial transactions conducted electronically on the internet. Includes digital payments, shopping carts, and fraud prevention. to treasury operations and remittances.
In cross-border payments, FX often involves physical settlement: the actual movement of currency from one account to another.
🧾 Simple Example: USD to EUR
- John (USA) wants to pay Bob (Germany) EUR 100.
- John holds USD at Bank of America; Bob holds EUR at BBVA.
- At an exchange rate of 1 EUR = 1.20 USD, John pays USD 120.
- BofA debits USD 120; BBVA credits EUR 100 to Bob.
But how does this actually happen behind the scenes?
🏦 Key Infrastructure: Nostro and Vostro Accounts
| Term | Definition |
|---|---|
| Nostro | An account a bank holds in a foreign bank, in the foreign currency |
| Vostro | An account a foreign bank holds in the domestic bank, in local currency |
📌 In our example:
- BofA’s Nostro account in BBVA (in EUR) is debited
- BBVA’s Vostro account in BofA (in USD) is credited
These accounts are maintained between correspondent banks to enable cross-border settlements.
