Russia has stated that for the ceasefire in the Black Sea to begin, certain sanctions against Russian banks must first be lifted and Russia must be reinstated into the international SWIFT payment system. According to Moscow, banks such as Rosselkhozbank, a state-owned bank linked to Russian agribusiness, should be removed from Western sanctions lists.
Interestingly, since the beginning of the Russian invasion, Russia has consistently dismissed sanctions and the removal of its financial system from SWIFT. The Russians even attempted to create an alternative to SWIFT but failed.
