Debit cards with no foreign transaction fees: who really charges zero in 2026

The three fee layers behind "zero"

Every foreign purchase pays up to three parties. First, the network: Visa and Mastercard convert at a wholesale rate they publish daily (Visa's calculator, Mastercard's converter), and that rate sits a small distance from the interbank mid-market. Second, the issuer: whatever your bank or card programme adds on top is the "foreign transaction fee" (PayPal's debit card charges 2.5%, Cash App's 3%, travel-oriented cards nothing). Third, on crypto-funded cards only, the conversion layer: somewhere between your stablecoin and the merchant's currency, someone converts crypto to fiat, and that step can carry its own fee or spread.

A "no foreign transaction fee" claim addresses the second layer. A card can honour that claim perfectly and still cost you 2% through the third layer, which is why the traps section below exists. When you compare cards, the number that matters is the end-to-end distance between the mid-market rate and what left your balance.

Five cards that publish a flat 0%

The five below are cards in our database whose current fee page states a flat 0% issuer markup on every currency, with no carve-out by region, currency or tier. Cards with a carve-out are in the next section. The "published FX line" column quotes the fee page and links to it; the last column is the cost that survives the 0%, taken from the same page. Three cards with a 0% line are left out on purpose: Cardano Card (4.4/5) and Wirex (4.1/5), because their rate is set by Wirex rather than taken from the network: Wirex's fee table lists the foreign transaction fee as free, but its terms add that "any associated mark-ups or fees will apply" and name no percentage (read 24 September 2026), and COCA (4.2/5), whose 0% covers direct pairs only (USD from USDT or USDC, EUR from EURC) and whose rate on other pairs (0.5-1.5%, confirmed to us in writing on 15 September 2026) is not yet on any public COCA fee page.

Four cards with a condition on the zero

The four cards below would sit in the table above if their 0% applied everywhere. Each is listed because the condition may not apply to you. Three more carry narrower zeros. Deblock is free on euro payments and on the first €1,000 a month in other currencies on its Standard plan, then charges 0.5% on weekdays and 1% at weekends. Holyheld's own pages advertise zero FX, but the issuer's fee schedule adds a 3% mark-up on any non-euro purchase, plus 2.5% and €1 outside the EEA. Tuyo's 0% covers only USD purchases inside the US: a purchase in another currency or outside the US pays up to 2%.

• Ether.fi Cash (4.9/5) publishes zero FX markup on euro purchases and is the card we measured at zero, but its FX article prices other currencies at a base rate of about 1% plus a tier markup of 0 to 0.5% on Core, 0 to 0.25% on Luxe, and none on Pinnacle or VIP. In euros or dollars it is a zero card. In yen it charges about 1% plus the tier markup.
• MetaMask Card (4.5/5): the fee table charges 1% cross-border on the free tier and no fee on the $199-a-year Metal tier, "subject to fair usage" per its footnote. The zero is a subscription feature, and Metal orders have been paused since 2 June 2026, so nobody can buy it today. The same table adds 0.5% on a stablecoin "denominated in currency not of cardholder country or merchant country", which a holder outside the US and Argentina pays even at home, because the card has no local-currency stablecoin. Separately, MetaMask has paused new sign-ups in the United States and the United Kingdom.
• Kraken Card (4.2/5): on the EEA and UK cards the pricing page says "We don't charge FX fees when you spend in foreign currencies. We pass on the Mastercard exchange rate without markup". The US card is different: "We pass on the Visa exchange rate and a 1% fee on debit card transactions". On every version, the card FAQ (2 September 2026) says Kraken "does include a spread in the price to sell the assets required to complete each transaction", and the size of that spread is not published.
• Gnosis Pay (4.2/5) has the cleanest 0% line of the group and closed to new signups on 30 September 2026: its 4 September 2026 notice disabled web-app signups that day, ended card signups on 30 September 2026, and said the card "will wind up in favour of partner cards by end of 2026". The formal notice of 21 September 2026 fixed the date: the card and web app stop working on 20 December 2026. Existing cards keep working until then. The named partner is Rebind, whose own fee page we could not read, so it is not in the table either.

Six ways a 0% claim hides a cost

Each pattern below is quoted from a fee page linked in the same sentence. Every 0% line is accurate, and none of them is the full price.

1. The fee next door. Bit2Me prints "Payments: Eurozone: €0" and, two lines up on the same fee page, "Transaction fee: Crypto: 0.95%". A euro purchase funded from crypto pays 0.95% before the FX line is even reached. Kraken's undisclosed sell spread, quoted above, is the same pattern without a number.
2. The regional or currency asterisk. Bit2Me again: €0 in the eurozone, 1.75% for "SEPA zone (non-Euro currencies)", 2% for "Worldwide currency payments". SwissBorg's FAQ (8 April 2026) says "foreign exchange fees may apply if you use your SwissBorg Card to make purchases in a currency different from your card's base currency (e.g., EUR, CHF, or GBP)" and gives no rate.
3. The tier asterisk. MetaMask's 0% lives on the $199 Metal tier (orders paused since 2 June 2026); the free card pays 1% at merchants outside your country, plus 0.5% when you spend a USD stablecoin and neither you nor the merchant is in the US. Ether.fi's 0 to 0.5% Core markup disappears only on the higher membership tiers. Both are on the issuer pages linked in the section above.
4. The network's own cut. Avici's fee page prints it: "Forex markups- 0%*" with the footnote "*Visa may charge a small 0.4-1% cross border fee for non-USD transactions". Ethena Pay says the same layer is "typically around 1%". Many fee pages do not mention it, and it applies to everyone who settles through the network rate.
5. The spread inside the quoted rate. No fee page itemises it, and that is where our measurement found the cost: 1.12 points of a Tria purchase's 2.64% total cost sat inside the issuer's own quoted rate, on top of the 0.50% fee the app showed at the Premium tier. You only find it by measuring, which is what the next section covers.
6. The document that disagrees with itself. UPay's India page says "UPay charges only 1% per transaction" and "zero fees for international transactions", while its support fee table, published as images, shows a 2% recharge fee at load and no per-transaction row. Tria's homepage says "0% Deposit & FX Fees" while its card terms (9 January 2026) put foreign exchange at "Up to 3%" and international transactions at "Up to 1%". When two published numbers conflict, price the worse one.

Two numbers we measured ourselves

Two numbers on this page come from our own settlements rather than a fee page: we ran the cards and compared the settlement against the ECB reference rate for the day. Ether.fi Cash settled a EUR 138.00 purchase on 4 August 2026 at an effective rate 0.015% below the reference, which is zero markup by any rounding, so the "true market conversion rate" the help centre advertises held on that day. Tria cost 2.64% over interbank on a euro purchase on 28 July 2026, decomposed as Visa's 1%, the 0.50% fee shown in the app at the Premium tier, and a 1.12% spread inside Tria's own quoted rate that appears on no fee line. The components round to 2.62; the settlement itself was 2.64. The full method and every subsequent measurement live on the advertised-vs-measured research page.

If you want a bank card

The mechanics are the same if you do not want a crypto product. At a bank, the foreign transaction fee is a line in the account's fee schedule, sometimes zero on travel-branded accounts, and the conversion itself happens at the network's wholesale rate regardless. Find the "foreign transaction fee" line in the schedule and confirm it says zero. Then protect that zero at the terminal by refusing dynamic currency conversion, the "pay in your home currency?" prompt whose rate is set by the merchant's acquirer and is usually worse than the network's. A 0% card charged through DCC is not a 0% transaction.

Stablecoin cards differ on dollar spending. A USD-denominated card treats US purchases as domestic, which a bank card in another currency cannot do unless the account holds dollars. Ethena Pay, Bleap and Bitpanda pass through the network rate on everything else. The price of that structure is the crypto leg, covered in our hidden FX fees guide, and the fee-by-fee comparison in our real-fees ranking.

Picking a card by spending pattern

If most of your foreign spending is in euros, Ether.fi's measured zero is the strongest evidence here, though it rests on one purchase. If you spend across many currencies from a stablecoin balance, Bleap and Ethena Pay pass through the network rate with nothing added, and Ethena publishes the clearest statement of what Visa's own fee then costs. If you are in the US and want a credit card, Gemini Credit is the 0% pick. If you hold a large balance and want a licensed bank underneath, Xapo works as long as the $1,000 membership already makes sense for other reasons.
