What Caused Black Friday In 1987?

The Stock Market Crash of 1987: A Day of Panic

Black Friday, also known as the stock market crash of 1987, was a day that sent shockwaves through the financial world. On October 19, 1987, the stock market experienced its largest single-day drop in history, with the Dow Jones Industrial Average plummeting by 22.6%. This unprecedented crash left investors and economists scrambling for answers, trying to understand what had caused such a dramatic event.

The Build-Up to Black Friday

Leading up to Black Friday, the stock market had been experiencing a period of significant growth. The Dow Jones Industrial Average had nearly tripled in value since 1982, fueled by a combination of economic factors, including low inflation, low interest rates, and increased corporate profits. This rapid growth had created a sense of euphoria among investors, leading to a speculative bubble in the stock market.

However, cracks began to appear in the market in the weeks leading up to Black Friday. On October 14, the stock market experienced a sharp decline, prompting fears of an impending crash. This initial drop was attributed to a variety of factors, including concerns about rising interest rates, political uncertainty, and overvaluation of stocks. These fears would prove to be just the tip of the iceberg.

The Trigger: Program Trading

While the exact cause of Black Friday remains debated among experts, one significant factor was the prevalence of program trading. Program trading refers to the use of computer algorithms to automatically execute large trades based on predetermined conditions. These programs were designed to exploit small price differences between stocks and stock index futures, a practice known as arbitrage.

On Black Friday, the market was hit by a wave of selling triggered by program trading. As the market began to decline, these programs automatically executed sell orders, exacerbating the downward spiral. The sheer volume of sell orders overwhelmed the market, creating a panic among investors and driving prices even lower.

The Domino Effect

As the stock market continued to plunge, the panic spread to other financial markets around the world. Stock markets in Europe and Asia also experienced significant declines, as investors feared the contagion effect of the crash. Banks and financial institutions were hit hard, with some facing severe financial strain.

The Aftermath: Lessons Learned

Following Black Friday, governments and financial institutions took steps to prevent a similar crash from happening in the future. Circuit breakers were implemented to halt trading temporarily in the event of significant market declines, giving investors time to reassess their positions and preventing further panic selling.

Regulations were also put in place to address the issues surrounding program trading. Measures were taken to increase transparency and oversight in the stock market, ensuring that the actions of these computer programs would not have such a devastating impact again.

The Legacy of Black Friday

Black Friday serves as a reminder of the inherent risks in the financial markets and the importance of prudent investing. It highlighted the dangers of speculative bubbles and the potential for rapid market declines. While the crash of 1987 was a significant event, it also served as a valuable lesson for investors and regulators, leading to improvements in market stability and resilience.

In conclusion, Black Friday in 1987 was caused by a combination of factors, including the speculative bubble in the stock market, fears of rising interest rates, and the prevalence of program trading. The crash sent shockwaves through the financial world, leading to significant declines in stock markets around the world. However, lessons were learned, and measures were implemented to prevent a similar crash from happening in the future.
