The 31.4% headline refers to a French budget amendment, not a tax already in force. Amendment I-CF1826 would make gains taxable when crypto is exchanged for qualifying MiCA e-money tokens from 1 January 2027; it proposes taxing the gain, not the full amount swapped. Official amendment text

Its sponsors say stablecoins can be used like investment assets or to make payments, so converting appreciated crypto into them should not defer the existing flat tax. The proposal would also set the received token’s acquisition value using the value already used to calculate the gain, avoiding tax on that same gain again when the stablecoin is later sold at that value. Amendment text

It is a proposed change to the 2027 Finance Bill, not an enacted rule. A rival amendment would preserve tax deferral for crypto to stablecoin swaps without additional payment. Opposing amendment I-3738
