Currency Conversion with Fees

Typical retail markups vs the mid-market rate: 0.5%–1% at fintech apps (Wise, Revolut), 2%–4% at major banks, 3%–6% at non-bank money transfer services, and 5%–10%+ at airport kiosks and hotel desks. On a $5,000 transfer, a 4% bank markup costs $200 - usually the largest hidden fee in the transaction.

The mid-market (interbank) rate is the midpoint between the buy and sell quotes large banks use to trade currency with each other. It's the "true" market rate you see on Google or XE.com. Consumers never get the mid-market rate exactly - the spread between mid-market and the rate offered to you is the provider's effective fee.

Use no-foreign-fee credit cards for purchases (typically priced near mid-market plus 0%–1%), withdraw cash from in-network ATMs with no-foreign-fee debit cards, send money via fintech transfer services rather than banks, and decline "Dynamic Currency Conversion" prompts at foreign POS terminals (always choose local currency).

DCC is a "service" foreign merchants offer to charge your card in your home currency instead of theirs. The exchange rate they apply is typically 3%–8% worse than your card network's rate. Always decline DCC and pay in the local currency - your card's network (Visa/Mastercard) gives you a much closer-to-mid-market rate.
