Cards & FX: stop paying the hidden markup.

On a CHF 20,000 annual spend with 30% in foreign currency, a 1.75% FX markup costs you CHF 105 a year you never see itemised. The right card stack erases it.

Estimated annual impactCHF 350
30-year compounded valueCHF 33,100

Three places the cost hides

Annual fees: CHF 0 to CHF 800 depending on tier. Most users pay for a tier they do not use.

Foreign currency markup: traditional Swiss bank cards charge 1.5–2.5% on top of the interbank rate every time you spend abroad - including online purchases in EUR or USD.

Cash withdrawal fees: 2–4% of the amount, plus a flat fee, every time you take cash from a foreign ATM.

The Pareto move
Carry two cards. One Swiss-issued credit card with strong purchase protection for CHF spending and big-ticket items. One zero-FX-markup card (Revolut, Wise, Neon, Yuh) for everything in foreign currency, online or abroad. Settle balances monthly. Never carry credit-card debt at Swiss interest rates (12–14%).

Indicative card cost on CHF 30,000 annual spend, 30% foreign currency.
DCC: always say no
Dynamic Currency Conversion is the prompt at foreign ATMs and POS terminals asking 'Pay in CHF?' Always decline. Pay in the local currency. Saying yes adds a 3–8% conversion markup before your card even sees the transaction.

Wallet cleanup checklist

  • List every card you carry, its annual fee, and its foreign FX charge percentage.
  • Cancel any card you have not used in six months that has a fee.
  • Open a free zero-FX card if you do not have one. Use only it for foreign currency.
  • Set up automatic full balance payment on every credit card. Never revolve.
  • When prompted abroad, always decline DCC. Always.
