Things are worsening all around. If they screw the USD, the Europeans are going to be more ticked at China's USD creeping peg, making it more likely China will do a 5% one-time change in the currency, which will import more consumer inflation to the US.
Debasing the USD just accelerates inflation. It's a horrible situation. Until the rest of the globe catches wind of the US slowdown, we're going to have a very tough environment for the Fed to navigate.
