The Great Depression Case Study: What Really Happened?

The Roaring Twenties (1920–1929)

The 1920s were one of the fastest-growing periods in U.S. economic history. Companies manufactured new goods — washing machines, cars, and more — and people bought them eagerly. Banks extended loans freely, giving people more spending power. The share market performed exceptionally well, and as companies raised more capital, they scaled up production to meet growing demand. This stretch of prosperity earned the era its nickname: the Roaring Twenties.

The Turn (1927–1929)

Around 1927, cracks began forming beneath the surface. Having watched investors profit handsomely from the share market, many people with no real investing knowledge entered the market and began buying stocks without any fundamental analysis. Stock prices climbed rapidly and became significantly overvalued — a textbook stock market bubble, even though few recognized it at the time. The market's dramatic climb continued through 1928 and into 1929, feeling like more of the same prosperity rather than a warning sign.

By August 1929, valuations had become extreme. At the same time, early signs of trouble were emerging elsewhere: economic growth had begun slowing since the start of 1929, company production was easing, people were losing jobs or having their wages cut, and poor weather conditions were battering the agricultural sector.

The Crash (October 1929)

Despite the mounting warning signs, investors kept buying in. The bubble finally began bursting on October 24, 1929 — "Black Thursday" — the first major day of panic selling. The most catastrophic single day came shortly after, on October 29, 1929 — "Black Tuesday" — when the market suffered its steepest decline of the crash, wiping out enormous value in a matter of hours.

This is also, roughly, why the "Roaring Twenties" ends where it does: the decade's defining prosperity collapsed right along with the decade itself.

The Depression Deepens (1929–1933)

What followed was a deep, sustained economic crisis lasting from 1929 to roughly 1933. Share prices ultimately fell by close to 90% from their peak. With confidence shattered, no one wanted to invest, leaving businesses starved of the funding they needed to recover. Meanwhile, the many people who'd lost their jobs stopped spending, which further starved businesses of revenue.

As people rushed to withdraw savings to survive, banks — many already strained from loans they couldn't recover from now-unemployed borrowers — began running out of cash and failing outright. Countless people lost a lifetime of savings in the process. By 1933, roughly 9,000 banks had failed, and public trust in the banking system collapsed — many people began keeping their money at home instead.

Hoover's Response — and Its Failures

President Herbert Hoover (the 31st U.S. President) presided over the early years of the crisis, and his policy responses largely backfired. Believing falling incomes needed to be offset, he pushed to keep consumer goods prices artificially high — even as poverty was already deepening and many Americans were selling their homes just to afford basic necessities.

Because domestic goods stayed expensive, Americans increasingly turned to cheaper imported goods instead. In response, Hoover signed the Smoot-Hawley Tariff Act (1930), imposing steep tariffs on imported goods specifically to push consumers back toward U.S.-made products. It didn't work — it mainly made already-scarce money stretch even less far for ordinary Americans, deepening the crisis rather than easing it.

Roosevelt's New Deal (From 1933)

In 1933, Franklin D. Roosevelt took office and moved quickly, enacting a wave of new policy within his first 100 days — a period now remembered as the "First Hundred Days." Two of the most consequential new institutions:

• The Federal Deposit Insurance Corporation (FDIC) — guaranteed that depositors would get their money back even if their bank failed, which restored enough public confidence for people to start depositing money again, putting cash back into circulation.
• The Securities and Exchange Commission (SEC) — established to regulate the share market and rebuild investor trust.

Roosevelt also used radio addresses (his famous "fireside chats") to directly reassure the public and maintain confidence through the recovery.

From 1933 to roughly 1937, the U.S. economy meaningfully improved. It then hit a genuine setback — now known as the Recession of 1937–1938 — a sharp, well-documented downturn caused in part by premature cuts to government spending and tightened monetary policy, which temporarily undid some of the recovery's gains.

Full Recovery (Around World War II)

The U.S. economy achieved full recovery from the Depression around the start of World War II. Massive wartime spending on the military and troops pushed enormous amounts of money back into circulation, finally pulling the economy fully back on track.

All told, the Great Depression is generally dated from 1929 to 1939.

That covers the core story of the Great Depression — how the Roaring Twenties gave way to a decade-long crisis, and how policy choices, both bad and good, shaped how it unfolded. Thanks for reading.
