The Federal Reserve printed $315 billion and used it to purchase Treasury securities and mortgage-backed securities as part of quantitative easing efforts to stimulate the economy during the COVID-19 pandemic. If that money was printed as $100 bills and stacked on pallets, it would fill over 3,000 standard semi-trailer trucks or cover over 1,000 football fields with bills one dollar thick. The unprecedented money printing highlights how massive the economic response has been to the pandemic.
