Currency, FX & Banking

For tracking spending across a trip, see Business Travel & Expense and Subscriptions & Billing. For getting cash on arrival, see practical rules below.

The four costs of money abroad: (1) the actual exchange rate, (2) FX markup (typically 0.5–4%), (3) cross-border / "foreign transaction" fees, (4) ATM fees. The right card and bank account zero out most of these.

Multi-currency / nomad-friendly accounts

• ★ ★ Wise (was TransferWise) — free account + paid debit card (~$9 one-time issuance, varies by country); ★ for sending FX cheap — true mid-market rate plus a small fee (0.4–0.6% typically). Hold 50+ currencies, get local IBAN/SWIFT in major ones. Card is great for spending; ATM withdrawals are free up to a small monthly cap then 2%.
• ★ Revolut — free + paid Plus / Premium / Metal (~$3–$15/mo); UK/EU origin, now broadly global. Good FX on weekdays (small markup on weekends), commission-free trading, vaults, group bills. Card is great daily-driver in EU.

• Monzo (UK) — free + paid Plus / Premium; great FX on Mastercard rate; £200/mo free ATM abroad.

• ★ GnuCash / Beancount — free OSS desktop; double-entry; the power-user pick for trip ledgers.

Practical rules (2026)

• ★ Always pay in local currency at the terminal. "Dynamic Currency Conversion" (DCC — "would you like to pay in USD?") adds 3–8% on top of your card's already-fair rate. Always say no.
• No-FX-fee cards make FX cards mostly redundant for spending — the value of Wise / Revolut is for sending money internationally, holding multi-currency balances, and ATM withdrawals.
• Notify your bank — though most major US/UK banks no longer require it, fraud algorithms still trip on first foreign use; have a backup card.
• ATM withdrawals: use bank-network ATMs, refuse the ATM's offered conversion (it's DCC again), watch for "out of network" fees on US Schwab Bank / Fidelity (★ both refund all ATM fees worldwide).
• Carry one backup card stored separately (in your hotel safe or with a partner). Plus ~$200 cash USD/EUR for emergencies.
• Crypto cards (Crypto.com, Binance) — generally not worth the hassle for travel; tax complexity outweighs marginal savings.
• Wise weekend FX surcharge — ~0.5% extra Sat/Sun.
• Apple Pay / Google Pay — increasingly accepted globally; some merchants only take chip-and-PIN — bring a physical card.

Cash-getting strategy

• Best: bank-network ATM in-airport at arrival; refuse currency conversion; use a no-fee debit card (Charles Schwab Investor Checking is the US gold standard).
• OK: pre-load Wise / Revolut and ATM-withdraw in local currency.
• Worst: airport currency-exchange counters; hotel exchange; "no fee" exchange offices in tourist zones (the spread is the fee).

Pick this if…

• Default FX card and "send money home" account: Wise.
• EU daily driver, weekday-heavy: Revolut.
• UK no-fee abroad: Monzo or Starling.
• US no-FX-fee credit: Chase Sapphire (Preferred or Reserve), Capital One Venture X, Bilt for renters.
• Currency converter on the road: XE or Wise app.
• ATM-fee-free worldwide (US): Charles Schwab Investor Checking debit.
