Summary

The Stock Market Crash of 1929, also known as the Great Crash or Wall Street Crash of 1929, was a pivotal event that commenced in October 1929 with a dramatic fall in stock prices on the New York Stock Exchange. Key dates include "Black Thursday" (October 24) and "Black Tuesday" (October 29), which saw record trading volumes and significant plunges in value. This crash is widely recognized as the catalyst for the Great Depression, which lasted until 1939. The preceding "Roaring Twenties" fostered widespread stock speculation, fueled by industrial growth and public investment in stocks due to low bank interest rates. However, underlying economic weaknesses, such as a struggling agricultural sector and reduced consumer purchasing power, meant stock prices were overinflated. The crash triggered a severe loss of confidence in the U.S. banking system and led to a market decline that continued until July 1932, by which point approximately 90% of its pre-crash value was lost. In response, Congress passed the Banking Act of 1933 (Glass-Steagall Act) to separate commercial and investment banking, and stock exchanges implemented measures to curb panic selling. The crash also significantly influenced the development of the US Securities Legislation of the 1930s-40s, which Kyle Samani of Multicoin Capital identifies as foundational to the "Legacy Financial System."

Wall Street crash of 1929

The Wall Street crash of 1929, also known as the Great Crash, was a major stock market crash in the United States which began in October 1929 with a sharp decline in prices on the New York Stock Exchange (NYSE). It triggered a rapid erosion of confidence in the U.S. banking system and marked the beginning of the worldwide Great Depression that lasted until 1939, making it the most devastating crash in the country's history. It is most associated with October 24, 1929, known as "Black Thursday", when a record 12.9 million shares were traded on the exchange, and October 29, 1929, or "Black Tuesday", when some 16.4 million shares were traded. The "Roaring Twenties" of the previous decade had been a time of industrial expansion in the U.S., and much of the profit had been invested in speculation, including in stocks. Many members of the public, disappointed by the low interest rates offered on their bank deposits, committed their relatively small sums to stockbrokers. By 1929, the U.S. economy was showing signs of trouble; the agricultural sector was depressed due to overproduction and falling prices, forcing many farmers into debt, and consumer goods manufacturers also had unsellable output due to low wages and thus low purchasing power. Factory owners cut production and fired staff, reducing demand even further. Despite these trends, investors continued to buy shares in areas of the economy where output was declining and unemployment was increasing, so the purchase price of stocks greatly exceeded their real value. By September 1929, more experienced shareholders realized that prices could not continue to rise and began to get rid of their holdings, which caused share values to stall and then fall, encouraging more to sell. As investors panicked, the selling became frenzied. After Black Thursday, leading bankers joined forces to purchase stock at prices above market value, a strategy used during the Panic of 1907. This encouraged a brief recovery before Black Tuesday. Further action failed to halt the fall, which continued until July 8, 1932; by then, the stock market had lost some 90% of its pre-crash value. Congress responded to the events by passing the Banking Act of 1933 (Glass–Steagall Act), which separated commercial and investment banking. Stock exchanges introduced a practice of suspending trading when prices fell rapidly to limit panic selling. Scholars differ over the crash's effect on the Great Depression, with some claiming that the price fluctuations were insufficient on their own to trigger a major collapse of the financial system, with others arguing that the crash, combined with the other economic problems in the U.S. in the 1920s, should be jointly interpreted as a stage in the business cycles which affect all capitalist economies.
