Swell idea, why didn't Zimbabwe think of that? Cause we all know, all it takes for a failed corrupt autocratic economy is to create its own national payment card (not accepted anywhere in the world), it's own SWIFT (not recognized by anyone) and its own rating agency (with the reputation similar to that of Pravda and RT) and right away all problems will disappear and they will become the financial capital of the world LOL

Of all the already failed Putin's undertakings, this sounds like the most idiotic.
