Not a history scholar, but an overgeneralization of parallels in modern US history.
1929 - 1932. Pretty weak banking system in USA. A lot of 'moral hazard' theorists who preferred to let weak economic entities die - survival of the fittest. Trade barriers. Partly as a result, stock market collapse, economic depression, deflation.
Post WWII. Incredible sovereign debt world wide. In the US, the Fed kept interest rates low for decades, in part to allow the economy to grow in relation to the war bonds and still be able to service the debt. Inflation eventually takes off when Nixon is in office. Inflation is finally throttled by the Fed in early 80's - that was painful.
Financial Crisis - Europe takes the route of austerity and scolds southern economies. Fed eventually takes the QE approach and buys up US Government bonds by the trillions - expanding money supply. US economic recovery leads Europe. Very little inflation - in fact inflation consistently undershoots the Fed target. Perhaps some of that is because Congress keeps issuing debt (Treasuries) at a record clip and soaking up the excess liquidity. Also because exporters like China accept dollars for goods sold, effectively importing USA inflation. Certainly some of the excess got stuffed into the stock market.
Pandemic - The Fed proves to be the only agency in the world to act quickly enough to keep markets from freezing up. They 'put money in the window' of the bank to keep confidence and liquidity. Necessary? Well yes - the whole house was on fire. Let's worry about the water bill next month. World wide, the dollar remains a stable value for countries. The Euro is starting to show cracks. The Yen hangs in there. And what elected world leader is going to trust the communist Chinese government anytime soon?
Stay tuned for how it turns out. My money is on the Fed almost getting things right as they balance inflation and job; but a long recovery until people come back out into normal habits again.
