This is really an issue, I'm still trying to place my finger on an opinion. The CBDC is great economic idea as transaction cost reduces, but the acceptability seems to be blurry, they all see it's value and are preparing to enter but haven't fully joined the idea which makes me think it's still theoretical until the move is established.
Anyways I'm sure trades are very vital to any nation and Russia is also important to other nation so eventually things will work out in their stead if they can hold on, but I think international trade with them might be secretive and I would how that will reflect on their GDP and currency valuation.
