The 1929 stock crash opened a decade-long global slump of mass unemployment, bank failures and falling prices.
See it on the Innovation & Wealth map →What happened
Stocks crashed on October 24 and 29, 1929; the Dow fell about 89% from its 1929 peak to July 1932. Bank runs closed about 9,000 US banks from 1930 to 1933, wiping out savings and shrinking the money supply by roughly a third. US output fell about a quarter, and unemployment reached about 25% in 1933. The gold standard spread deflation abroad, and tariff wars helped world trade collapse. Farmers, workers and small savers suffered most; holders of cash and safe bonds fared best.
Impact on society and the economy
It discredited hands-off finance and produced deposit insurance, securities regulation, Social Security and Keynesian economics. It remains the benchmark for every later crisis.
Think of it like
Like a market where forced sales push down comps, lenders call loans, and more owners must sell: a downward spiral.
How we know
Stock prices, bank-failure counts from the Fed and FDIC, Commerce Department output estimates, later-reconstructed unemployment data, and studies by Friedman and Schwartz, Bernanke and Eichengreen.
Still debated
Its causes are still debated: Federal Reserve mistakes, the gold standard, collapsing spending, debt burdens or bank panics. Most economists now blame a mix.

▸Federal Reserve Act failed to prevent Crash of 1929 and the Great DepressionDebated
The connection
The Fed was built to stop panics, yet from 1930 to 1933 it let about 9,000 banks fail and the money supply shrink by about a third. In 1931 it even raised interest rates to defend the dollar's gold value. Milton Friedman and Anna Schwartz argued in 1963 that these mistakes turned a recession into the Great Depression.
When and how
Washington and New York, 1928–1933; Fed officials, adrift after the 1928 death of New York Fed leader Benjamin Strong; later analysts Friedman, Schwartz and Ben Bernanke.
How sure are we?
Money-supply and bank-failure data, Fed records, and Bernanke's 2002 remark as a Fed governor: 'Regarding the Great Depression, you're right, we did it. We're very sorry.'
Debates
Others, such as Barry Eichengreen, stress gold-standard limits and collapsing spending; whether the Fed could have acted differently under its rules is still debated.
▸Crash of 1929 and the Great Depression led to The New DealWell documented
The connection
Three years of slump made Herbert Hoover's cautious approach politically untenable. Franklin Roosevelt, promising 'a new deal for the American people,' won 42 of 48 states in 1932. He took office on March 4, 1933, as banks failed across the country, declared a national bank holiday two days later, and launched the Hundred Days of emergency laws.
When and how
Washington, 1932–1933; Franklin Roosevelt, his 'Brain Trust' of advisers such as Raymond Moley, Rexford Tugwell and Adolf Berle, and a Democratic Congress.
How we know
Election returns, Roosevelt's speeches and fireside chats, and the laws passed in spring 1933 show the direct response to the crisis.
Debates
Hoover had begun some interventions, such as the 1932 Reconstruction Finance Corporation, so historians debate how sharp a break the New Deal really was.
▸Crash of 1929 and the Great Depression was the benchmark for 2008 financial crisis and the Great RecessionMostly agreed
The connection
Fed chair Ben Bernanke had spent his career studying how the 1930s Fed let banks fail and money shrink. In 2008 the Fed cut rates to near zero, lent trillions and bought bonds, while governments rescued banks and spent on stimulus, deliberately avoiding 1930s mistakes. The slump was named the 'Great Recession' by comparison.
When and how
Bernanke's research from 1983 and his 2002 promise to Milton Friedman that the Fed would not repeat the Depression; Washington, 2008–09, with Henry Paulson and Timothy Geithner.
How sure are we?
Bernanke's memoir The Courage to Act (2015), Fed records, and his 2022 Nobel Prize for research on banks and financial crises.
Debates
Whether the rescue prevented a second Depression, as most economists believe, or mainly protected bankers and inflated later asset bubbles.
▸World War II mobilization and wartime research ended the mass unemployment of Crash of 1929 and the Great DepressionMostly agreed
The connection
US unemployment was still about 15% in 1940. Then war spending and the draft absorbed the idle: federal spending roughly quadrupled as a share of output, about 12 million people were in uniform by 1945, and unemployment fell to about 1% in 1944. Mass joblessness, the Depression's defining feature, was gone within three years.
When and how
United States, 1940–1944; the Roosevelt administration, the War Production Board and the Selective Service draft.
How sure are we?
Bureau of Labor Statistics unemployment estimates and Commerce Department output and budget data show the timing clearly.
Debates
Did the war end the Depression or merely mask it? Keynesians see a test of deficit spending; skeptics note that the draft, rationing and price controls made it unlike peacetime.
