After the financial crisis of 2008, the Federal Reserve used two policies to prop up the economy: zero percent interest rates and pumping newly-created money into the economy through quantitative easing (QE). Because of 40-year-high inflation, the Fed has recently reversed policy and is raising its key interest rate target on overnight loans between banks. The Fed is also doing quantitative tightening (QT, the opposite of QE), and is withdrawing money from the economy.
