America entered the 1920s with a new sense of confidence and left the decade in economic freefall. This special traces the consumer boom of the Roaring Twenties, the mechanics of the 1929 stock market crash, and the chain of events that turned a financial panic into the decade-long Great Depression. It's an essential primer for students trying to understand how prosperity can mask fragility.

Key Takeaways

• By 1929, Americans owned 80% of all the cars in the world, and nearly 70% of homes had electricity, up from 30% at the decade's start.

• Buying stocks on margin allowed investors to purchase shares with borrowed money, paying only a fraction of the actual price, which massively amplified losses when prices fell.

• On Black Tuesday, October 29th, 1929, a staggering 16.5 million shares were traded on the New York Stock Exchange as prices collapsed.

• Ford Motor Company stock fell from $100 per share to $36 after the crash. Sears, Roebuck plummeted from $149 to $34.

• The Smoot-Hawley Tariff Act of 1930, intended to protect American jobs, triggered retaliatory tariffs from trading partners and helped push unemployment from 6% to 20% by 1932.

Questions & Answers (FAQ)

Q1: What caused the stock market crash of 1929?

Multiple factors converged. Easy credit and margin buying had allowed investors to purchase stocks with far more borrowed money than they could cover if prices fell. When prices began declining in September 1929, margin calls forced panic selling, which drove prices down further, triggering more selling. Speculation had inflated stock values well beyond what underlying corporate earnings justified, and when confidence broke, the collapse was rapid and severe.

Q2: What is buying stocks on margin and why was it dangerous?

Buying on margin meant an investor paid only a small percentage of a stock's price upfront and borrowed the rest from a broker. If the stock rose, the returns were magnified. If it fell, the investor still owed the full borrowed amount. When the 1929 crash hit, millions of investors who had bought on margin faced margin calls requiring them to immediately cover their losses, forcing mass selling that accelerated the collapse.

Q3: What was the Smoot-Hawley Tariff Act and did it make the Depression worse?

The Smoot-Hawley Tariff Act, signed by Hoover in June 1930, imposed tariffs on over 20,000 imported goods. It was intended to protect American jobs by making foreign products more expensive. Instead, trading partners responded with their own retaliatory tariffs, collapsing international trade. Most economists today view Smoot-Hawley as having significantly worsened the Depression, contributing to the rise in unemployment from 6% to 20% over the following two years.

Q4: How did Herbert Hoover respond to the stock market crash?

Hoover initially relied on indirect measures and voluntary cooperation from business leaders, urging them to maintain wages, keep enterprises open, and continue investing. He believed the market would self-correct. He also pushed state governors to increase public spending. These steps were insufficient given the scale of the crisis. His signing of the Smoot-Hawley Tariff in 1930 made conditions significantly worse, and by 1932 his presidency was defined by the Depression's human toll.

Q5: When did the Great Depression end and what ended it?

The Great Depression effectively ended in 1941, when American mobilization for World War II produced massive government spending and returned the country to full employment. Franklin Roosevelt's New Deal programs, begun in 1933, provided significant relief and reformed financial regulations, but did not fully end the Depression. It was the wartime economic expansion that finally closed the unemployment gap that had opened in 1929.

The Roaring Twenties

The year was 1920, just two years after victory in World War I. The nation that had grown from 13 colonies into a continental power was now the wealthiest on earth. America had a newfound sense of confidence. Unprecedented prosperity lay ahead. 20% of American families had automobiles that year. By 1929, 60% of them owned cars. Americans owned 80% of all the cars in the world. In 1920, 30% of American homes had electricity. By the end of the decade, nearly 70% did.

Electricity powered a boom in new-fangled devices: radios, vacuum cleaners, washing machines, and refrigerators. The 1920s was the age of American jazz, the flapper, and art deco. It was the peak decade of silent movies. We call it the Roaring Twenties. But the decade didn't end with a roar. It ended with a crash, the stock market crash of 1929. The American free-market system reaches back to the founding generation we cover in our episode on the Constitutional Convention.

A Bull Market and Buying on Margin

On March 4th, 1929, Herbert Hoover was inaugurated president of the United States. An engineer by training, he was America's first Quaker president. His vice president, Charles Curtis, was the first and only person of Native American descent to hold that office. Hoover was a mix of conservative and progressive sensibilities, a Republican who had served in the administration of progressive Democrat President Woodrow Wilson. In the first months of Hoover's administration, the American economy was booming.

The stock market was a bull market. Sales were soaring, prices rose, profits were up, and investor confidence was growing. Easy access to credit allowed individual Americans and companies to borrow money to invest in the stock market. This allowed investors to pay only a small percentage of the stock's price and borrow the rest, what is called buying stocks on margin. On September 3rd, 1929, the bull market slowed down dramatically. For the long arc of how American economic power developed, see our episode on America's paradox of slavery and freedom.

Black Thursday, Monday, and Tuesday

Major panic struck on October 24th, 1929, Black Thursday. What followed was an unprecedented spike in selling and a sharp drop in stock prices. Attempting to stabilize the market, a group of leading bankers led by Charles Mitchell of National City Bank bought large blocks of shares. The banker's strategy momentarily interrupted the market decline. Then came Black Monday, October 28th, 1929. The stock market experienced another severe downturn. Investor confidence eroded further. Finally, the great crash: Black Tuesday, October 29th, 1929. The most catastrophic drop in stock market history.

A staggering 16.5 million shares were traded on the New York Stock Exchange. Prices collapsed. Ford Motor Company went from $100 per share just before Black Tuesday to $36 a share. Sears and Roebuck, America's largest retailer, plummeted from $149 to $34 a share. The crash triggered a wave of bank runs. Having lost faith in the financial system, depositors withdrew their money all at once. 659 banks closed in the immediate aftermath of the crash. Consumer spending plummeted. Businesses faced reduced demand. Industrial production declined. Farmers were hit hard by a collapse in food prices and a surge in bank foreclosures.

Hoover's Response and the Great Depression

The great stock market crash was soon followed by the Great Depression, a prolonged national and global economic downturn. At one point, President Hoover believed that the market and the economy would correct themselves. On the day after Black Tuesday, he remarked: "The fundamental business of the country, that is, production and distribution of commodities, is on a sound and prosperous basis." Still, Hoover took some steps to intervene. He encouraged industry leaders to invest in construction and state governors to increase public spending. He charged businessmen to keep their enterprises open, maintain stable price and wage levels, and avoid laying off workers. Within a month of Black Tuesday, 9% of Americans were off the payrolls. By June of 1930, unemployment had dropped to just over 6%.

That same month, however, Hoover signed into law a set of tariffs on over 20,000 foreign imports, the Smoot-Hawley Tariff Act. Within six months, the jobless rate rose to double digits and stayed there for the remainder of the decade. In 1932, 20% of Americans were without jobs. That same year, Hoover lost his bid for reelection. Franklin Delano Roosevelt roared into the White House with a trainload of new government programs. He called it the New Deal. The Great Depression lasted until 1941.
