I believe governments around the world will hyperinflate their problems 'away' as their 'solution' before they introduce a new digital currency (debt write-off), but wirst we need a huge deflation problem that will make everybody WANT their new-privacy-killing-digital-solution.
DXY will take a big hit as something has got to give. The US will try everything to keep american companies alive and thus the stock markets up. Its all a temporary solution and printing more money is not a solution. They can try to (hyper)inflatie the debt away, but in the end a write-off is the only solution.
