If you have ever wondered what the Great Depression was and why this event is still studied by economists today, here is the answer: it was one of the most devastating economic crashes in human history, and its lessons remain relevant even now.

It all began in October 1929 with the so-called Black Tuesday. A crash occurred on the U.S. stock market, which literally wiped out the savings of millions of people within days. But it was not just a stock market panic — it was a trigger that launched a chain reaction that engulfed the entire world and continued into the late 1930s.

What caused such a collapse? First, a speculative bubble. In the 1920s, people invested in stocks like crazy, often borrowing money. When prices started to fall, investors panicked and began selling everything indiscriminately. Prices plummeted even faster. This was followed by bank bankruptcies — people who lost their savings began mass withdrawals, leading to the collapse of financial institutions. Without deposit insurance (which did not exist at the time), people lost everything.

But that was not all. Governments began imposing protective tariffs like the Smoot-Hawley Tariff in the U.S., trying to protect domestic industry. Instead, they provoked a trade war. Global trade plummeted in free fall, which further worsened the situation.

The result was catastrophic. Unemployment in some countries reached 25 percent. People lost their jobs, companies closed, homelessness grew exponentially. It was not just an economic problem — it was a social and political catastrophe that changed societies.

The recovery from the depression was long. When Franklin Roosevelt came to power in the U.S., he launched an ambitious program called the New Deal. The government began actively intervening in the economy, creating jobs through public works, regulating banks and the stock market. Many countries implemented unemployment insurance and social protection systems.

The economy fully recovered only after World War II began. Mass production of weapons created jobs and revitalized industry.

Why is all this still important? Because history shows how vulnerable an economic system can be when proper regulation and protection are absent. After the 1930s, policymakers and regulators realized that mechanisms were needed to prevent such crises. Deposit insurance, securities regulation, social programs — all are direct results of that era.

For people interested in market cycles and crypto-assets, the history of the Great Depression is a reminder that markets can be cruel and unpredictable. Speculation, borrowing, panic — these factors remain relevant in today’s world. Understanding what happened in 1929 helps better grasp how markets are structured today and why caution is necessary.
