Market fluctuations can be unnerving, especially in times of uncertaintyTo better navigate these turbulent waters, it is essential to reflect on historical events that have shaped the financial landscapeOne such pivotal moment in history was the infamous market crash of 1987, which serves as a cautionary tale for investors even today

On October 19, 1987, a day now marked in infamy as Black Monday, the world witnessed an unprecedented collapse in the stock market.

The United States stock market plummeted in a manner that had not been seen since the Great DepressionThe Dow Jones Industrial Average fell a staggering 508 points, which accounted for a loss of 22.6% in a single day— the largest drop in its history at that time

Over the course of just 6.5 hours, the New York Stock Exchange lost an astounding $500 billion, an amount equivalent to one-eighth of the entire United States' annual GDP.

The fallout was not contained to the U.S.; the entire globe felt the repercussions of this economic turmoilMost major corporations saw their stocks decline by about 30%. For instance, General Electric dropped by 33.1%, AT&T fell by 29.5%, Coca-Cola fell by 36.5%, and Boeing was down by nearly 30%. Such a dramatic decline in stock prices ignited fears of a global recession and financial chaos.

Economists at Merrill Lynch referred to this period of volatility as the “great slaughter” due to its brutal effects on wealth and confidence in the market.

The Hong Kong Hang Seng Index dropped more than 11% on the same day, leading to an emergency halt in trading for four days

When trading resumed on October 26, the market crashed again, this time by an overwhelming 33.3%, which established a new record for the largest single-day stock market loss in history.

While many investors feared that this crash marked the beginning of a new financial catastrophe, it was not as severe in the long term as the Great Depression of 1929. Remarkably, the stock market found its footing rather quickly; by a mere two years later, it had rebounded and surpassed its previous highs.

This observation led to the realization that crashes, although alarming, can serve as mere ripples in the larger economic tide, particularly if the fundamentals of the economy remain strong.

The aftermath of the 1987 crash provided numerous lessons about market cycles, investor psychology, and the importance of understanding the economic context in which these events occur.

Before the crash, the early 1980s saw the end of stagflation as energy prices dropped, leading to a booming economy

The United States adopted a “new economic policy” that stimulated fiscal expansion, lowered taxes, and attracted foreign investmentThis period of growth became known as the “Reagan economic miracle.” Moreover, interest rates were dropping, resulting in an unprecedented increase in stock valuations and earnings.

By September 1987, the S&P 500 had skyrocketed by 215% compared to its lowest point in 1982. That year alone saw a remarkable return on the index, with a cumulative increase of 36.2%. This surge was notably driven by rising valuations as the price-to-earnings (P/E) ratio of the S&P 500 doubled from under 10 to around 20.

Another critical element prompting this economic growth was the significant depreciation of the U.S

dollar from 1985 to 1987, where it fell from 164 to around 100— a nearly 40% decreaseThis depreciation led to increased profits for U.Scompanies when earnings were calculated in domestic currency, further driving interest in the stock market.

Despite the positive economic indicators, the market crash came as a surprise to many investorsOn the day of the crash, there were no significant negative news reports that would typically precipitate such a rapid declineHowever, sentiment was a fragile construct, and investor behavior can be unpredictable.

Many experts pointed fingers at computerized trading as a significant contributor to the crashThe rise of algorithmic trading began in the 1970s, and by the 1980s, quantitative investment strategies were gaining momentum.

An example of this lies with Renaissance Technologies, a well-known quantitative investment firm that developed sophisticated trading algorithms which may have exacerbated the panic selling during the market downturn.

When stocks began to fall, automated trading systems activated selling strategies, leading to a cascading effect that made the situation far worse

These programs often operated on impulse, which meant that falling prices triggered a wave of panic-selling across the board.

However, it is important to note that while algorithmic trading was prevalent in the U.S., it was not as widespread internationally at the time— for example, Hong Kong's market experienced significant declines that day but was less influenced by computerized strategies.

The days leading up to Black Monday contained significant shifts in economic sentimentReports indicated that the U.Sgovernment was considering increasing capital gains taxes, which created alarm among investorsFurthermore, metrics showed escalating trade and budget deficits, undermining confidence.

Perhaps most importantly, over the weekend preceding the crash, the U.S

Treasury Secretary alluded to the possibility of active dollar devaluation, raising concerns about outflows of capital.

This scenario provided a clear catalyst for the Hong Kong market's steep dive on October 19, as the local currency was pegged to the U.SdollarThus, investors braced for sell-offs on both sides of the Pacific.

The final nail in the coffin came at approximately 1:09 PM on October 19, when an ominous announcement from a regulatory authority suggested the possibility of temporarily closing exchangesThis statement instantly triggered massive sell orders, creating a perfect storm of panic and chaos.

In the wake of such an unprecedented crash, the response of the U.S

government and the Federal Reserve was criticalFollowing the crash, measures were taken to inject liquidity back into the marketGovernment officials emphasized the stability of the economy and dispelled panic as the economy faced uncertainty.

In an unusual move, Federal Reserve Chairman Alan Greenspan and Treasury Secretary James Baker were swiftly called back from overseas missions to manage the situationBy October 20, emergency statements were released affirming the readiness of the Federal Reserve to provide liquidity and support to banks engaged in stock trading.

In retrospect, the rapid response from policymakers and the Federal Reserve is credited with stabilizing the financial system

Many companies announced stock buyback programs, highlighting confidence in their own valuations, which further buoyed morale in the aftermath of the crash.

The Federal Reserve introduced measures including bond purchases and lowered interest rates, making funds more accessible for businesses and investors alikeThe strategy of bolstering liquidity effectively instilled confidence that the financial crisis could be managed.

Ultimately, the 1987 stock market crash serves as a profound lesson in the volatility of financial markets and the importance of responsive leadership in times of crisisAlthough the aftermath could have caused significant economic turmoil, the economy itself was fundamentally sound, and the crisis proved to be a mere correction rather than the onset of a deep recession.
