The Russians have not put the rouble on some sort of gold standard. Instead, they have repeated the Nixon/Kissinger strategy which created the petrodollar in 1973 by getting the Saudis to agree to accept only dollars for oil. This time, nations deemed by Russia to be unfriendly will be forced to buy roubles – roughly 2 trillion by the EU alone based on last year's natural gas and oil imports from Russia — driving up the exchange rate. The rouble has now doubled against the dollar from its low point of RUB 150 to RUB 75 yesterday in just over three weeks. The Russian Central Bank will soon be able to normalise the domestic economy by reducing interest rates and removing exchange controls

The Russians and Chinese will be acutely aware that Western currencies, particularly the yen and euro, are likely to be undermined by recent developments. The financial war, which has always been in the background, is emerging into plain sight and becoming a battlefield between fiat currencies, and it is full on.

The winner by default is almost certainly gold, now the only reliable reserve asset for those not aligned with Russia's "unfriendlies". But it is still a long way from backing any currency.

Putin is losing the battle for Ukraine

President Putin is embattled. His army as let him down — it turns out that his generals lack the necessary leadership qualities, the squaddies are suffering from lack of food, fuel, and are suffering from frostbite. It is reported that one brigade commander, Colonel Yuri Medvedev, was deliberately run down by one of his own men in a tank, a measure of the chaos at the front line. And Putin is not the first national leader to have misplaced his confidence in military forces.
