The Hidden Cost of Forex Fees in Crypto Cards
Most issuers charge a massive markup when you spend outside your home currency.
The reality of cross-border spending
If you live in the US and travel to Europe, you spend in euros. If you buy software online from a UK company, you pay in pounds. Cross-border spending is unavoidable. Traditional banks penalize this behavior with a foreign transaction fee, usually around 3%. Many crypto cards adopted this exact same model. They market themselves as borderless finance, but they use traditional banking rails to penalize you for crossing actual borders. It is a massive contradiction in the product.
How network markups drain your balance
When you buy a €100 dinner in Paris with a typical crypto card, two things happen. First, the issuer charges their standard crypto-to-fiat conversion spread. Second, they apply a foreign exchange markup to convert your account balance to euros. The Visa network sets a baseline exchange rate, but the issuer adds 2–3% on top of it. Your €100 dinner ends up costing you significantly more in crypto. You lose capital to the conversion twice in a single swipe.
Calculating the true cost of travel
Let us quantify the damage. Assume you spend $5,000 on foreign transactions a year. This includes travel, international software subscriptions, and imported goods. A standard 3% forex fee costs you $150 annually. Over three years, you lose $450 just for the privilege of spending your own money in a different currency. Add a 0.6% forex fee on top of the base card rate, and your total cost climbs even higher. You are funding the issuer's margin every time you leave your home country.
The TXBFI approach to foreign exchange
TXBFI charges a flat 0.6% forex fee on currency conversion — and we publish it openly. There are no hidden layered markups. When you spend in euros, yen, or pounds, we use the mid-market rate and apply 0.6% on top. Nothing more. You still pay our transparent 3% deposit fee when you load the card, but forex transactions are straightforward. A €100 dinner costs you exactly the market rate plus 0.6%. Your money works the same way in Tokyo as it does in your hometown.
