Not inflation but hyperinflation. But the thing is everything if fluid nowadays with all the countries free to trade with everybody and good free to move everywhere so easily and so fast, it's hard to have hyperinflation nowadays.
It ends when they lose control of current conditions (as they always have mismanaged historically by the end). Just know it ends very badly for reasons that are very obvious.
Hyperinflation?? Even Socialist Venezuela recently dollarized their economy, after their currency the "Bolivar" collapsed, which brought down inflation somewhat. Now all the need is to send Maduro back to his busdriver job. What currency will Americans turn to when the dollar finally throws in the towel? And more importantly when. Which is anyone's guess.
If the attack on the Capital would have been successful and Congress was shut down for a long period of time the Fed would stop printing money. Are you familiar with the expression "The only time the country is safe is when Congress is not in session." Sad but true.
.Russian ruble and Chinese yuan. You will have to smuggle the $US out of the country as the government introduces currency controls.
If central banks don't want to lose reserve currency status, they have to stop QE and 0 rate at some point. Otherwise USD & EUR would be replaced by gold as reserve. Recession can happen immediately when ultra easy monetary policy ends. This will be the first recession in recent history for which Fed has no ammunition to fight. When 2000 and 2007 bubbles burst, Fed fund rate was above 5% and QE hadn't started.
Wow... good point! What do you think of this idea: the Fed has its back to the wall if something else happens. Could they amp up their money printing to 240B, or 1T a month? Set negative interest rates? Real Rates are actually negative now. 1987 crash, 2001: 9/11, 2009: Mortgage Crisis, 2020: COVID... another "big thing" is coming in the next ten years that will hit markets hard. With hundreds of billions of monthly QE already in place, and 0 interested rates, what do we do when that next big thing hits? Uncle Jerome has probably lost some sleep over this.
