In the annals of financial markets, stock crashes have been a defining feature, often reshaping the landscape of the economy and investor sentiment. From the infamous Wall Street Crash of 1929 to the tech bubble burst in the early 2000s, the United States has witnessed numerous stock market crashes that have had profound effects on the country and the world. In this article, we explore the ten biggest stock crashes in US history, delving into their causes and their impact on the market.
1. The Great Crash of 1929
October 29, 1929: This day is often referred to as "Black Tuesday." The stock market experienced a dramatic fall, with the Dow Jones Industrial Average plummeting by 13% in a single day. The crash was primarily caused by excessive speculation and stock prices that had far outstripped their underlying value.
2. Black Monday (1987)
October 19, 1987: Known as Black Monday, this was the single-worst day in Wall Street history, with the Dow Jones Industrial Average falling by nearly 23%. The crash was attributed to computerized trading and the lack of effective risk management.
3. Dot-com Bubble Burst (2000-2002)
The dot-com bubble, which reached its peak in 2000, saw the NASDAQ Composite Index skyrocket as investors bet heavily on technology stocks. However, by 2002, the bubble burst, and the NASDAQ fell by more than 80% in value, wiping out $5 trillion in market capitalization.
4. Financial Crisis of 2007-2008
September 15, 2008: This was the day Lehman Brothers filed for bankruptcy, marking the beginning of the financial crisis. The crisis was triggered by the collapse of the subprime mortgage market and the subsequent failure of financial institutions. The Dow Jones Industrial Average fell by over 40% between September 2008 and March 2009.
5. October 1987 Crash
Referenced earlier, the 1987 crash was the most significant single-day drop in the history of the stock market, with the Dow Jones Industrial Average plummeting by nearly 23%.
6. The Panic of 1893
In 1893, the Panic of 1893 led to a severe depression that lasted for years. The crash was primarily caused by the collapse of the Jay Cooke & Company, one of the nation's largest banking and financial institutions at the time.
7. Silver Crash of 1893
Following the Panic of 1893, the silver crash further exacerbated the economic downturn. The crash was caused by the government's decision to remove the gold standard and introduce the silver standard, which led to a massive devaluation of silver.
8. The 1920 Crash
The 1920 crash was caused by a speculative bubble in the stock market, which led to a sharp decline in stock prices. The crash was a precursor to the Great Crash of 1929.
9. The 1989 Stock Market Crash
October 19, 1989: The crash was triggered by a large sell-off in the Tokyo Stock Exchange, which spilled over into the US markets. The Dow Jones Industrial Average fell by over 7% in a single day.
10. The 2010 Flash Crash

On May 6, 2010, the stock market experienced a brief, dramatic collapse, with the Dow Jones Industrial Average plummeting by nearly 9% in a matter of minutes before rebounding. The crash was attributed to a software error that triggered automated trading systems.
These crashes serve as a reminder of the volatility and risk inherent in the stock market. As investors, it's important to understand the historical context of these events to better navigate the markets and manage risk.
