The ruble and other currencies do not compete against the dollar. They are dollar derivatives.
The dollar is headed to ruin, but that doesn’t mean that any other paper currency can replace it. The others will fail first.
The dollar will fail last.
The failure of the dollar, and the transition to gold happens to be the theme of an event The Gold Standard: Both Good and Necessary, in New York on Nov 1. There hasn’t been a real recovery from the crisis of 2008, and there won’t be until we return to the use of gold as money. Please come to this event to hear Andy Bernstein present the moral case for capitalism, and Keith Weiner present the case against the dollar and for the gold standard.
