I mean, the conclusion of this post isn't precisely claiming a USD victory:

And I agree. I don't think the Renminbi will necessarily take over, but I also don't think the dollar will maintain the strong dominance it has on global trade and as a reserve currency.

Noah Smith agrees as well:

I think the system is stable instable:

Dollar Inflation will continue. China will continue to have problems investing its trade surpluses sensibly. Western policy towards Russia and China will become even more hostile, but it will not come to a big bang.

At some point, we will realize that we have to solve the problems together, perhaps the Bancor will be introduced after all.
