Russia and China both are accumulating a lot more gold than previously. They can go to a gold backed digital currency pretty reliably at this point. China's been testing digital yuan already, including some nice restrictions that will benefit socialist/communist control - restriction of what certain digital yuan can buy, as well as time-expiring money. Both would increase peoples needs on the state and their short term happiness - they'll feel "richer" able to buy nicer meals or go on vacations, but both would be able to restrict someone from saving or becoming too successful. We'll likely see these same ideas implemented in the CBDCs that roll out in the west.

"Oil backed" makes less sense, IMO.
