"Currency fees" on a card are a stack of separate costs: the **spread** (3 to 6% baked into the rate by big banks), the **foreign transaction fee** (up to 3% on most cards), and **DCC** (4 to 7% if you accept paying in your home currency). Zeroing one layer is not enough.
The single biggest lever for a US traveler is a **no foreign transaction fee** card. That 3% surcharge on every purchase in a foreign currency adds up to real money over a trip.
**Chase Sapphire Preferred and Reserve, most Capital One cards, and Amex travel cards** charge no foreign transaction fee. They use the Visa, Mastercard, or Amex network rate, which is close to the interbank rate.
**DCC (Dynamic Currency Conversion)** is the invisible trap. Whenever a terminal or ATM asks "pay in USD or local currency?", the answer is **always local currency**. Accepting USD costs 4 to 7% more.
**Multi-currency accounts** like Wise and Revolut give you near-interbank rates by letting you hold and convert balances ahead of time. Useful for long trips and digital nomads.
