Hello @crypto.piotr friend, I believe that the exclusion of Russia from the Swift system will not be a direct sanction for the government, but for the citizens of that country, since many of them need to make transfers and send/receive international remittances in some way, some for work or family reasons. and commercial.
I think the citizens will be the most affected.
In the same sense, I think that somehow the exclusion of Russia from the swift system could trigger some kind of blockade in shipments and supplies of fuel, gas and oil to other countries, which although they are far from the conflict, will pay these consequences.

All in all, it's still worrying.
