The whole situation is complex. I believe they are setting the stage for the IMF to use their SDRs (Special Drawing Rights) to replace the dollar as the worlds reserve currency. The SDRs are backed by a basket of currencies. Could this be the end of the King Dollar? If the U.S. strengthens the dollar as Trump is trying to do by shoring up our potential economic and dollar demise, then maybe the dollar will not be replaced by the SDRs. Who knows???
