The short answer
For restaurants, start with a no-foreign-fee American Express Gold when Amex is accepted: it earns 4× worldwide and Amex applies Argentina’s tourist-dollar treatment. For general purchases, compare the final Amex conversion with your highest-value no-foreign-fee Visa—often a Sapphire card—and carry that Visa as your acceptance backup. Neither network literally uses the street ‘blue dollar’ rate, and Amex is not guaranteed to beat Visa on every transaction.
Compare the cards I haveWhat to use—and when
Best first try for restaurants
American Express Gold
It earns 4× at restaurants worldwide, has no foreign transaction fee, and foreign-issued Amex cards receive Argentina’s tourist-dollar treatment. Acceptance can be more limited than Visa.
Essential backup
No-foreign-fee Visa
Visa says its foreign-card rate is slightly below the dollar MEP rate and applies instantly. A Sapphire card also avoids foreign fees and may win on rewards, protections, or acceptance.
Usually avoid
Freedom Unlimited
Its 3% foreign transaction fee usually costs more than its incremental rewards, even if you pool its points into a Sapphire account.
Decision rules
- Ask to pay in Argentine pesos (ARS). If the terminal offers U.S. dollars, reject that conversion and let the card network convert the charge.
- Compare final dollars charged—not the first pending amount. American Express says its tourist-rate adjustment can take up to two statement cycles.
- Choose the card with the best net result: tourist conversion + category rewards − foreign transaction fee. Network alone does not determine the winner.
- Keep a no-foreign-fee Visa available because Amex acceptance is not universal.
Common traps
- The ‘tourist dollar’ is not the informal street blue-dollar rate. Visa describes its foreign-tourist rate as slightly below the legal dollar MEP rate.
- An Amex purchase can initially look expensive because the regular conversion may post before a separate tourist-rate adjustment.
- A merchant’s offer to charge in dollars is dynamic currency conversion, not a way to guarantee a better U.S. exchange rate.
- Do not choose Amex solely because it once beat Visa. Rates move daily, posting dates differ, and card rewards can outweigh a small FX difference.
The practical two-card strategy
At a Buenos Aires restaurant, try Amex Gold in pesos for 4× rewards. If Amex is not accepted, use a no-foreign-fee Sapphire Visa in pesos. For a general retail purchase, compare your cards in SwipeCue because Sapphire’s transferable-point value may beat a slightly better Amex conversion—and review the Amex result only after any adjustment posts.
Questions people actually ask
Does American Express get a better exchange rate than Visa in Argentina?
Sometimes the final Amex result may be better, but it is not guaranteed. Both networks advertise special treatment for foreign-issued cards, their timing differs, and Amex may send a later adjustment. Compare final posted dollar amounts for purchases made close together.
Is the tourist-dollar card rate the same as the blue dollar?
No. The blue dollar is an informal cash-market quotation. Visa describes its foreign-tourist card rate in relation to the legal dollar MEP rate, while Amex calls its treatment the Tourist Dollar exchange rate.
Should I choose dollars or pesos at the terminal?
Choose Argentine pesos. A dollar option lets the merchant or terminal perform the conversion and can embed a poor exchange rate. Use a card with no foreign transaction fee and let its network convert the charge.
