No country wants to be subject to removal from SWIFT an the whim of the US Government so dozens of bilateral and multilateral currency agreements have been or are now being negotiated between our enemies and even our "friends" to circumvent sanctions and transact in their own currencies (Saudi Arabia and China for example or the BRICS countries). The result is that there will be less need for countries to hold Dollar reserves and it's value will decline significantly meaning much higher prices for everything we import devastating our already stressed Middle Class and our inability to print money with impunity. Get prepared for unprecidented Inflation in the future.
