I really had to hunt for an article which told me what I wanted to know. As of January 2013 new banking rules called Basel III, put together by the global bankers (higher than the so-called Illuminati) went into effect; one of which concerns the move to backing currencies with gold again. The U.S. balked (another case of the leaders of the U.S. thinking they are exceptional??) and so far, only a few countries have begun to embrace the new rules.
(Now you know why Germany wanted their gold back but the EU balked, too, because the U.S. balked.)
The Basel Committee on Banking Supervision (BCBS).
(I wouldn’t call them the banking mafia but I didn’t write the article.)
