Quote from morganist:
How could it be a depression if it lasted a year. This is different it is not based on liquidity it is insolvency and demographic.
It was more like 2-3 years and it was generally accepted as a depression when it happened. From 1919-20, federal spending was reduced 65 percent. The New York Fed raised its discount rate to a record high 7%. From its peak in June 1920, the CPI fell 15.8 percent over the next 12 months. I wouldn't exactly say those were normal times.
