The EU might have slept on Russia having to urgently come up with its own payment systems after the 2014 Crimea annexation (which in turn enabled it to deal with the complete Visa/Mastercard exit in 2022) because political goals were aligned and transatlanticism was still alive and well. But they've been wide awake ever since ICC employees have been personally sanctioned by the US as well [1].

Big ships turn slowly, but I give it at most two more years until at least one pan-European retail payment scheme (cards, QR, or maybe the "digital Euro") has been regulated into existence.
