The Great Depression resulted from several connected structural weaknesses, while the Wall Street Crash of 1929 acted as an important trigger. It was not caused by the stock-market crash alone.
The central mechanism was a collapse in spending, credit and confidence. During the 1920s, speculation pushed share prices beyond the underlying value of many companies, often through buying shares “on margin” with borrowed money. When prices fell sharply in October 1929, investors lost wealth and confidence, reducing consumption and investment.
Bank failures then intensified the downturn. Banks had made risky loans and lacked strong federal protection; when depositors rushed to withdraw money, many banks collapsed. Credit became less available, businesses reduced production and employment, and falling incomes caused demand to decline further.
| Cause | How it contributed |
|---|---|
| Stock-market speculation | Inflated share prices and made the financial system vulnerable to panic. |
| Easy credit and debt | Consumers and investors borrowed heavily, making spending difficult to sustain. |
| Overproduction | Agricultural and industrial output exceeded effective demand, causing falling prices and profits. |
| Unequal income distribution | Limited the purchasing power of many households and encouraged reliance on credit. |
| Banking weakness | Bank failures destroyed savings and restricted lending. |
| International debts and tariffs | War debts, US lending and protectionism weakened global trade and transmitted the crisis across the Americas. |
A key misconception is that the Wall Street Crash directly caused every aspect of the Depression. The crash was a catalyst, but structural problems made the downturn severe, while banking collapse and contractionary policies prolonged it.
Exam technique: For a Paper 3 causal essay, classify factors as long-term weaknesses, short-term triggers and factors that deepened the crisis. Build a comparative argument about their relative importance rather than narrating events, and connect US developments to export-dependent economies elsewhere in the Americas.
