Revaluation of Gold by China or Russia?
100:19 perhaps a Chinese or Russian unilateral revaluation of gold, like the US did in 1933, or a refusal to accept dollars, might do the trick.
One way China or Russia could increase the value of their reserves without having to buy more gold is to revalue the price of gold. The US/London market may not respect the price but sellers would sell their gold to the Chinese and other eastern exchanges to get the higher price, thereby giving the east more gold and more pricing power over it.
