The 1929 Wall Street Crash - A defining moment in financial history

Introduction

The late 1920s seemed like a time of hope and growth. But beneath the surface something weak was building. Then in 1929 came the stock market crash, and with it a long, hard period called the Great Depression.

In this article we will explore: what caused the crash and the depression, how people and economies were impacted, and what lessons we can learn from it.

1. What Happened in 1929: The Crash

In October 1929, shares on the New York Stock Exchange (NYSE) collapsed in value. One famous day is called Black Tuesday (October 29). Markets had been rising for years, many people were borrowing money to buy shares, and when confidence faltered the fall was steep.

Banks, investors and ordinary people lost huge amounts of money and many found themselves in trouble.

2. Key Causes of the Crash & Depression

Here are several important factors:

๐Ÿ“Š Speculation and Margin Buying

Many people invested in shares using borrowed money, hoping the price would keep rising. When prices stopped rising, the system cracked.

Weak Banking and Money Supply Problems

Banks failed, and the money circulating in the economy dropped. Many loans could not be paid back.

๐ŸŒ Global Links and Trade Problems

The U.S. economy was connected to other countries. When one part failed, the problems spread. Policies like tariffs (taxes on imports) also made trade harder.

Over-production and Fall in Demand

Factories produced more goods than people could buy. When demand dropped, production slowed, jobs were lost.

3. What Was the Impact?

The shock was deep and long-lasting. Some of the effects:

~50%

Industrial output in the U.S. fell by almost 50% in the early years of the Depression.

Unemployment shot up โ€” millions of people lost their jobs. Many families struggled to find food, shelter and basic comfort.

Banks closed, savings were lost, and trust in financial systems was shaken.

๐ŸŒ

The depression spread across the world, hitting Europe, Latin America and other regions too.

4. Important Lessons From the Great Depression

โš ๏ธ Don't Rely on Endless Growth Without Safety Nets

When things grow too fast without control, they can collapse.

Strong Institutions Matter

Banking systems, clear rules, transparent markets help avoid panic.

Trade, money, and economic health are shared across nations.

๐Ÿค When People Lose Confidence, the Economy Suffers
