But the record is pretty clear, there are a limited ways out of this situation.
1) Default on your debt : The US is never going to do this. It would be insane given the global position of the dollar and the fact that the fed can always buy treasuries to finance debt
2) Run persistently high inflation: This is how the US managed it's debt after WW2 : Real rates were around -15% for the better part of the decade. And at the end bond holders were screwed and the country was solvent.
3) Hyper inflate : basically off the table for the dollar given the huge structural demand for dollars and also going back to the point that the Fed doesn't want to short term implode all global capital markets.
4) Pull a japan and have no growth for a third of a century.
The easy choice is # 2. We have to have inflation. The supply chain stuff is just a detail.
CPI for energy is 25% percent right now. I've seen a figure for housing sales prices at around 17. Spy is up 33% year on year. Bitcoin is up I think about 600 yoy. The inflation writing is on the wall.
