The Great Depression after the 1929 stock market crash

What was the Great Depression that followed the 1929 stock market crash?

The Great Depression was a long economic slump in the United States that spread through the gold standard to other countries. The Federal Reserve History essay dates its start to August 1929, when the expansion of the Roaring Twenties ended, which is 2 months before the October crash.

The crash was the first signal, not the whole story. The effects of the crash faded within a few months, and by fall 1930 recovery seemed imminent. Then problems in another part of the financial system turned a downturn into the Great Depression. The sections below follow that turn in numbers.

Which causes turned a stock market crash into a decade of crisis?

The detail page on Great Depression causes weighs the main explanations. The Federal Reserve raised rates in 1928 and 1929, repeated the move during the international crisis of fall 1931, and failed to act as lender of last resort during the banking panics of 1930 to 1933. Each error deepened the slump.

Other explanations add to the Fed’s record. The Smoot-Hawley Tariff Act passed Congress on 17 June 1930 and, according to Wikipedia, worsened an otherwise standard recession. The gold standard carried the downturn across borders, and Irving Fisher’s debt deflation shows how falling prices made debts heavier.

When did the Great Depression begin and end after the crash?

The start and end dates depend on the source. The Federal Reserve History essay dates the Depression from August 1929, places the trough in March 1933 when Roosevelt declared a national banking holiday, and sees output and employment return to full levels during World War II, by 1941. Wikipedia dates it from 1929 to 1939.

A second dip complicates the picture. A recession in 1937 interrupted the recovery, and Wikipedia ties it to the rollback of reflationary policies and to the Banking Act of 1935, which raised reserve requirements. The page on Great Depression years sorts these dates into a timeline that a reader can reuse.

How many workers lost jobs in the Great Depression after the crash?

Unemployment gives the human measure. Wikipedia reports 23.6% by 1932 and a peak of 25% in early 1933. The rate then eased, but it jumped from 14.3% in 1937 to 19.0% in 1938 during the second dip, and it dropped to about 2% in the early 1940s.

Those percentages mean one worker in 4 without a job at the worst point. The page on Great Depression unemployment follows how far the crash pushed jobs down and how long the high rates lasted. Readers can compare the shape with later downturns by looking at the duration, not only at the peak.

How did bank failures deepen the Great Depression after the crash?

Banks carried the next stage. According to Wikipedia, 744 U.S. banks failed from the 1929 panic through October 1930, and 608 more closed in November and December 1930. By 1933 about 9,000 of the 25,000 banks in the country had gone out of business, while the Fed had failed to act as lender of last resort during the panics.

The collapse of the commercial banking system led Roosevelt to declare a national banking holiday in March 1933, and the holiday lasted 5 days. The Emergency Banking Act of that year set up a system for reopening sound banks under Treasury supervision. The page on Great Depression bank failures explains the sequence of the panics.

How much did output and prices fall after the 1929 stock market crash?

Output and prices fell together. Wikipedia reports a 30% contraction of U.S. GDP across 1929 to 1932, and an estimated 15% fall in world GDP over the same period. From fall 1930 through winter 1933 the money supply fell by nearly 30 percent, and average prices fell by a similar amount.

Falling prices made debts heavier, which is the heart of the debt-deflation account. The Dow tells the market side of the same story: it closed at 41.22 on 8 July 1932, 89% below its peak, and it regained the 1929 high only on 23 November 1954.

Which rules did the Great Depression after the crash produce?

The crisis rewrote the rulebook. The Banking Act of 1933, known as Glass-Steagall, was signed by Roosevelt on 16 June 1933. It separated commercial banking from investment banking and created the Federal Deposit Insurance Corporation. The temporary fund insured deposits up to $2,500 from January 1934, and the permanent fund raised the limit to $5,000 from July 1934.

Other reforms followed: the Emergency Banking Act of 1933, the Gold Reserve Act of 1934, and the Banking Act of 1935. The page on the New Deal and Glass-Steagall explains each rule and what it changed. Wikipedia dates the suspension of the gold standard to March 1933 and Executive Order 6102 to 5 April 1933.

What does the Great Depression after the crash teach investors today?

Three lessons stand out for a reader today. First, a stock fall can precede a larger financial event that unfolds over years. Second, banks and the money supply matter as much as share prices. Third, rules written in a crisis change the risks of the next one.
