Explain the causes of the Great Depression, including the stock market crash of 1929, overproduction, uneven wealth, weak banks, and buying on margin and credit (Tennessee Academic Standards for Social Studies, United States History and Geography, US.21).

What this topic is asking

Standard US.21 asks what caused the Great Depression. For the EOC that means understanding that the stock market crash of 1929 was the trigger and symbol, but the real causes were deeper economic weaknesses: overproduction and underconsumption, the uneven distribution of wealth, reckless speculation and buying on margin, weak banks, and too much reliance on credit and debt. Items often give a chart or a quotation and ask you to identify a cause.

The stock market crash of 1929

Through the 1920s the stock market rose far beyond what company profits justified, inflating a speculative bubble. In October 1929 confidence broke and prices collapsed, with Black Tuesday (October 29) the most famous day. Billions in paper wealth vanished.

Buying on margin and speculation

Overproduction and uneven wealth

Two linked problems undercut the boom:

• Overproduction and underconsumption. Factories and farms produced more goods than the public could buy, so inventories piled up, prices (especially farm prices) fell, and businesses cut back and laid off workers.
• Uneven distribution of wealth. A large share of income went to the wealthy, while many workers and farmers earned too little to keep buying. When their spending could not sustain the economy, demand collapsed.

Weak banks and too much credit

The banking system was fragile and largely unregulated. When the crash and falling demand hit, thousands of banks failed. Because there was no federal deposit insurance yet, failing banks wiped out ordinary people's savings, which destroyed spending and confidence further. Households and businesses had also relied heavily on installment credit and debt during the boom, leaving them exposed when incomes fell.

Tariffs and the global slump

To protect American industry, Congress passed the high Smoot-Hawley Tariff (1930). Other countries retaliated with their own tariffs, and international trade collapsed, spreading and deepening the Depression worldwide.

Why this matters for the EOC

This topic is a classic cause-and-effect item: the EOC may give a chart (stock prices, bank failures, unemployment) or a list and ask you to identify a cause, or to distinguish the trigger (the crash) from the underlying causes (overproduction, uneven wealth, weak banks, margin buying, tariffs). It connects directly forward to the human experience of the Great Depression and the response of the New Deal.

Try this

Q1. Explain the difference between the trigger of the Great Depression and its deeper causes. [2]

• Cue. The trigger was the 1929 stock market crash; the deeper causes were overproduction, uneven wealth, margin buying, weak banks, debt, and high tariffs.

Q2. Explain why bank failures made the Depression worse. [2]

• Cue. Thousands of banks failed and, with no deposit insurance, wiped out people's savings, destroying spending and confidence.
