Great Hypothesis! Very likely in my opinion.  Another way the U.S. could cement itself again is to strategically delay or inhibit Swift from creating a CBDC style central ledger system that doesn’t require Treasuries as collateral like in the current Eurodollar system.  It’s a Win-Win.   A Fight for freedom railing against CBDC’s & simultaneously holding onto global demand for treasuries. 

 Nice, I like that idea too!
