When the market crashed in 1929, banks issued margin adjustments. Due to the huge number of shares purchased on margin by the general public and the lack of cash on the margin, entire portfolios were liquidated. As a result, the stock market plummeted lower. Many investors were wiped out and the Federal Deposit Insurance Corporation (FDIC), which guarantees depositors' funds, didn't exist back then.
Many Americans began to withdraw their cash from banks, while banks, which granted too many bad loans, suffered significant losses. The stock market crash of 1929 was due to overspeculation in the 1920s, which included investors using borrowed money to buy stocks. The FDIC was created because, as the stock market fell, thousands of people began to withdraw their money from banks. As a result, by the end of the decade, many investors had bought massive amounts of shares, but mainly through loans and a minimum investment of approximately 10%.
Stock prices continued to fall until 1932, when the Dow Jones industrial average, a widely used benchmark for front-line stocks in the United States, closed at 41.22, its lowest value in the 20th century, 89 percent below its peak. The lack of government oversight was one of the main causes of the 1929 crash, thanks to laissez-faire economic theories. People borrowed money to invest in the stock market, which meant that stocks were bought with loans rather than cash. In fact, the Dow Jones Industrial Average (DJIA) didn't hit bottom until July 8, 1932, when it had fallen 89% from its peak in September 1929, making it the largest bear market in Wall Street history.
The market had been on a nine-year streak and the Dow Jones Industrial Average increased tenfold, peaking at 381.17 on September 3, 1929.Most investors shared their method and invested thousands of borrowed dollars in the stock market in various industries and products that didn't have time to mature and be considered a proven, even valuable, product. However, investment simply stagnated, rather than falling; that stagnation was an indication that the market simply could not support more investment. From 1921 to the summer of 1929, the stock market had grown at an exponential rate, largely as a result of the investment of borrowed money in the stock market. At the same time, creditors who had lent to investors began to demand repayment of loans after watching market profits begin to spiral.
This may have weakened Americans' confidence in their own companies, although it had minimal impact on the London Stock Exchange. While all of the above-mentioned financial problems contributed to the collapse of the economic market, the failure of the leadership of US presidents during the 1920s may have been the main catalyst for the Great Depression. While the price of many major front-line stocks fell, smaller companies suffered even more, forcing companies to file for bankruptcy. The stock market crash of 1929 was not the only cause of the Great Depression, but it did act to accelerate the global economic collapse of which it was also a symptom.
Stock prices began to fall in September and early October 1929, and on October 18, a major decline in stock prices began.
