The de-dollarization trend continues. The IMF is likely to add the Chinese yuan to its basket or reserve currences, i.e. USD, sterling, yen, euro.  China's goal is of course for the yuan to become the global reserve currency, and Middle East countries have recently been supporting non-USD oil trades. With the amount of dollars out there worldwide, if it loses favor confidence in it could fall quickly. This isn't something which will happen overnight, but it'll be interesting to see its effect 10 years from now.
