Twelve trillion roubles...Petro gone from the dollaris what the world needs to purchase by currency conversion from dollars euros yen etc.. Russia will only sell oil (and other commodities) in rubles. The 12T is just for the oil.
Germany and many others will need to convert euros etc. by a mechanism where the Russian supplier immediately buys rubles and dumps euros etc. This is how the dollar hegemony ruled.
The ruble will of course strengthen. In addition the Russian central bank will buy gold at 5k rubles per gram. As the ruble goes up so does the gold price. Putin and gang has set up a conveyor system to buy gold, strengthen ruble and weaken euro dollar and yen.
So much for the west trying to cripple Russia. All great for gold and our favourite miner.
