Honestly, when I study the history of financial crises, I constantly come across one question: what was the Great Depression, and why are its lessons still relevant today? Recently, I reread materials about this period and realized that many modern traders are not even aware of how similar the crash patterns are.

The Great Depression did not start with a single event. It was a perfect storm of several factors. In October 1929, the famous stock market crash occurred — the so-called Black Tuesday. Prior to that, ten years of frantic speculation took place, asset prices were artificially inflated, people borrowed money and invested in stocks. When investors finally saw through the illusion and started selling, a chain reaction was inevitable.

But what is the Great Depression without a bank crash? Panic spread like wildfire. Depositors withdrew their money en masse, banks closed one after another. Without deposit insurance, people lost everything they had saved. Loans were cut back, and the economy froze.

The wave swept across the entire world. Europe, weakened by World War I, collapsed first. Governments began imposing tariffs like Smoot-Hawley in the US, trying to protect local producers. The result was the opposite — international trade plunged into a abyss, and other countries responded in kind.

Unemployment reached 25 percent in developed countries. People queued for bread, companies shut down en masse. These were not just numbers — they were millions of broken lives, families losing everything.

What’s interesting is that emerging from this nightmare required radically new approaches. Roosevelt launched the New Deal — large-scale public works, banking regulation, deposit insurance. It was revolutionary for its time. Governments took responsibility for economic stability.

World War II accelerated recovery — military production created millions of jobs. But the main thing that happened was a rethinking of the role of the state in the economy.

Today, when we see volatility in crypto markets or crises like 2008, we look through the lens of what happened in the 1930s. What is the Great Depression for the modern investor? It’s a textbook on how quickly a system can collapse if there are no reliable protection mechanisms.

Insurance systems, regulation, social guarantees — all of this was born from the experience of that era. We live in a world built on the lessons of the Great Depression. And it’s important to remember this when you see how quickly the market can change.
