When the financial collapse in 2008 was analysed by the Fed, they knew that the system could no longer function as it should and they would need a new reserve currency, this is why the SDR was created by the IMF, it's the last clean balance sheet.
No longer will every asset be pegged to the USD, but to the SDR, a basket of currencies: the USD, the EURO, the YEN, the Pound Sterling and the Renminbi all have a place in this model.
As the USD is beeing rejected worldwide, it might loose one of its most important support ankers:
- The USD was used as a national currency and will remain doing so.
- The USD was also used for the oil trade, this will no longer be the case in the future as more and more countries trade oil without using USD's.
- The USD is also used by a few countries who don't have their own currency.
In the near future all global currencies and assets will be pegged to the SDR.
I haven't fully found out ow exactly this is all serving the most rich people on this earth, but it wuldn't surprise me that this new system gives them more power and control.
