Causes
Stock-exchange speculation led hundreds of thousands of Americans to invest heavily in the stock market, creating an economic bubble. Many were borrowing money to buy more stocks.
"At the turn of the 20th century, stock market speculation was restricted to professionals, but the 1920s saw millions of 'ordinary Americans' investing in the New York Stock Exchange. By August 1929, brokers had lent small investors more than two-thirds of the face value of the stocks they were buying on margin – more than $8.5bn was out on loan".[5]
The amount of money out on loan was more than the entire amount of currency circulating in the US at the time.[6] When a stock price declined below the amount of borrowed money, the owner had to sell to pay the debt. This caused prices to decline more. Years later, regulations limited the use of debt in this way.[source?]
