Unfortunately for Russia, if it does need to significantly dip into it's gold reserves it is likely to crash that market. I think China will get to negotiate a sweet discount to convert it to Yuan, if for no other reason than China seems to be the only place the gold can be laundered at the moment. I think I heard about $US 180bn worth?

Pretty much all of Russia's liquid cash is in physical gold and bills, it'll be interesting to see how that's getting moved and used.
