Yeah, if you’re interested in this stuff, you should do some research. The Fed’s options aren’t 0% rates vs 15% rates. It’s going to raise rates .25% at a time. .25% is not much of a difference. It’ll move slowly and act cautiously.
The Fed, and other central banks have dealt with inflation many times before. And very effectively at that. Stocks could fall, but the stock market is not the economy, and the Fed has no mandate to prop up stocks.
