At one point it was reported Trump damn near threatened to fire Powell. It was asinine. If you want to see investors truly lose confidence have them think the Fed is doing the President's bidding. Generally speaking, Wall St loves easy money and it's not about Biden, Trump, Obama, Bush etc. They want the Fed to leave the easy money punch bowl in place. This isn't a partisan thing, it's a money thing. But what's good for the stock market isn't always good for Main St and the rest of us. That's the problem with the Fed catering to Wall St and investors.
Yes DJT was constantly on Powell's ass over rates and for good reason but remember, whatever you think of Trump personally he was a whiz at crating theater. And Powell knew this as did Wall Street.
Yes Wall Street loves the Fed pumping, makes them a LOT of money. But the difference between DJT and Biden is Trump was preparing for the monster rebound that Joe had handed to him (and is squeezing the life out of). Both knew/know that it can only go so far. Joe adds trillions more fiat currency needlessly and now we have a problem we would not have had with Trump.
