Black Monday: When the markets lose their minds

The pages of financial history hold many instructive lessons. One of them is the infamous Black Monday of October 19, 1987, when global stock markets experienced an unprecedented crash. This event left a deep scar on the psyche of investors and rewrote the rules of the game in the securities market. Today, as cryptocurrencies gain momentum, the story of Black Monday becomes more relevant than ever.

When History Happened: The Crash That Shook the World

October 1987 started like any other month. But on the 19th, something happened that changed the financial industry forever. The Dow Jones Industrial Average (DJIA) plummeted by 22.61% in a single trading day — this remains one of the most dramatic one-day declines in stock market history.

The scale of the catastrophe was beyond comprehension. If an investor had put $100,000 in on Monday morning, by the close of that trading session, that amount had turned into $77,390. The crash sent waves of panic around the globe: European exchanges, Asian markets, Australian markets — chaos and despair were seen everywhere.

The System Failed: Why the Crash Became Inevitable

Black Monday was not a sudden lightning strike, but rather the result of the accumulation of many dangerous factors.

Speculative Bubble of Overvaluation. By the mid-1980s, stocks had soared to the skies. Investors were buying stocks on borrowed funds, hoping for continued growth. When the first cracks appeared in the structure of this bubble, a panic sell-off began. This is where the snowball effect kicked in: the more people sold, the lower prices fell, and the more intense the selling became.

Computers Took Control. By the late 1980s, trading had entered the digital age. Computerized trading systems were programmed to automatically sell assets when the index fell below a certain threshold. This logic seemed reasonable in theory, but in practice, it led to increased volatility. When thousands of algorithms received a sell signal simultaneously, machine panic occurred — a situation that no one fully controlled.

International Tension and Monetary Policy. High interest rates made borrowing expensive. Geopolitical tensions added to the uncertainty. All of this created conditions where investors were already on edge, waiting for any excuse to retreat.

Consequences That Changed the Rules

The financial crisis of 1987 cost the markets trillions of dollars in lost capital. But it was not just about the numbers — it was a loss of trust. Ordinary people, who had invested their retirement savings, saw their future evaporate in one day.

However, from this crisis, wisdom was born. Regulators quickly realized that protective mechanisms were needed. The so-called “circuit breakers” were introduced — rules that temporarily halt trading during a critical index drop. This gives the market time to “catch its breath” and investors time to recover.

Restoring trust took years, and some investors never returned to the stock market.

Cryptocurrencies: New Scenes for an Old Play?

Today, looking at the cryptocurrency markets, an uncomfortable question arises: could history repeat itself? The parallels are obvious and concerning.

Volatility as Essence. Crypto markets inherited volatility from traditional finance and multiplied it several times over. Here, movements of 10-20% can occur in hours, while in traditional markets, such changes happen over months. This creates a fertile ground for panic.

Algorithms Again as Main Characters. Cryptocurrency exchanges are literally permeated with high-frequency trading and bots. This means that under certain conditions, the market may experience artificially intensified drops when machines “panic” ahead of human panic.

Lack of Protective Mechanisms. Unlike regulated stock markets, the cryptocurrency ecosystem remains a wild territory. There are no “circuit breakers,” no unified regulation. When a sell-off begins, nothing stops it.

Speculative Origins. Many crypto projects are bought on waves of hope, rather than based on fundamental analysis. At the first sign of trouble, speculators scatter in all directions.

Protection: A Strategy for the Rational Investor

Market storms cannot be prevented, but one can prepare for them.

Diversification as a Shield. Do not keep all assets in one position or even in one market. If the crypto market crashes by 50%, traditional assets, commodities, or precious metals may remain relatively stable. This is not insurance, but a safety cushion.

Loss Limiting Tools. Use stop-loss orders on crypto exchanges. A pre-set selling level will spare you from having to make emotional decisions in the heat of panic. This is a mechanical approach, but it works when emotions run high.

Psychological Preparedness. History shows that the main enemy of an investor is not the market crash, but their own panic. Those who kept a cool head in 1987 and afterward often found themselves in a winning position when the markets recovered. Black Monday teaches us: calmness is not a sign of indifference, but a sign of professionalism.

A Portion of Earnings, Not Savings. Invest only what you can afford to lose without upending your life. A classic piece of advice, but in the era of volatile crypto markets, it becomes not just advice, but a necessity.

Black Monday was in 1987, but its lessons are still relevant today. Markets will rise and fall. It is important not to succumb to the illusion that “this time it will be different.” This time — it will not be. History repeats itself, but the wise learn from the mistakes of others.
