The Yuan certainly won't become the currency of record. The Russian economy isn't doing that great and the Ruble is depressed.

And specifically, they delve deeply into the poorly-understood topic of why Chinese demand has become such a game changer in recent years."
Perhaps but the idea of a devalued dollar is not a stretch if the Petro-Dollar is weakened by sufficient non-dollar denominated energy and commodities purchasing. China, Russia, India, Iran, and any ankle biters could put a major tear in that Petro-Dollar. HOW MUCH would it hemorrhage is the better guess then IF it would.
