Unfortunately decoupling payments within the EU is insufficient if the US can just threaten to sanction your bank, and in doing so force the bank to drop you as a customer. Even in the presence of an internal European payments network, those banks still need to transact with the US and other US-sphere countries...

No but then you can have local bank that will not have US interactions but can still serve you. Since the French judge of the IPC was sanctioned, it’s clear that the EU must completely decouple from the US.

For now, but not forever. Skate to where the puck is going to be. Decoupling continues, with the target being independence. Quote this comment five years from now.
