The Great Depression: Overview, Causes, and Effects (2024)

What Was the Great Depression?

The Great Depression was a devastating and prolonged economic recession that followed the crash of the U.S. stock market in 1929. It lasted through 1941, the same year the United States entered World War II. The period was marked by several economic contractions, including the stock market crash of 1929, banking panics that occurred in 1930 and 1931. and the Smoot-Hawley Tariff that crashed world trade. Other events and policies helped to prolong the Depression during the 1930s.

Economists and historians often cite the Great Depression as the largest if not the most catastrophic economic event of the 20th century.

The Stock Market Crash

The U.S. stock market fell by nearly 50% and corporate profits declined by over 90% during a short depressionknown as the Forgotten Depression that lasted from1920 to 1921. The U.S. economy enjoyed robust growth during the rest of the decade. The American public discovered the stock market and dove in headfirst during the Roaring Twenties period.

Speculative frenzies affected both the real estate markets and the New York Stock Exchange (NYSE).Loose money supplyand high levels ofmargin tradingby investors helpedfuelan unprecedented increasein asset prices.

The lead-up to October 1929 saw equity prices rise to all-time high multiples of more than 19-times after-tax corporate earnings. Coupled with the benchmark Dow Jones Industrial Index (DJIA) increasing500% in just five years, this ultimately caused the stock market crash.

The NYSE bubble burst violently on Oct. 24, 1929, a day that has come to be known as Black Thursday. A brief rally occurred on Friday the 25th and during a half-day session on Saturday the 26th but the following week brought Black Monday (Oct. 28) and Black Tuesday (Oct. 29). The DJIA fell by more than 20% over those two days. The stock market would eventually fall almost 90% from its 1929 peak.

Ripples from the crash spread across the Atlantic Ocean to Europe,triggering other financial crises such asthe collapse of the Boden-Kredit Anstalt, Austria’s most important bank. The economic calamity hit both continents in full force in 1931.

The U.S. Economy Tailspin

The 1929 stock market crash wiped out nominal wealth, both corporate and private, and this sent the U.S. economy into a tailspin. TheU.S. unemployment rate was 3.2% in early 1929. It soared to over 25% by 1933.

The unemployment rateremained above 18.9% in 1938 despite unprecedented interventions and government spending by both the Hoover and Roosevelt administrations. Real per capita gross domestic product (GDP) was below 1929 levels by the time the Japanese bombed Pearl Harborin late 1941.

The crash likely triggered the decade-long economic downturn but most historians and economists agree that it didn't cause the Great Depression by itself. Nor does it explain why the slump's depth and persistence were so severe. Avariety of specific events and policies contributed to the Great Depression andhelped to prolong it during the 1930s.

Mistakes by the Young Federal Reserve

The relatively newFederal Reservemismanaged the supply of money and credit before and after the crash in 1929, according to monetarists such asMilton Friedmanand acknowledged by former Federal Reserve ChairBen Bernanke.

The Fed was created in 1913 and it remained fairlyinactive throughout the first eight years of its existence. Then it allowed significantmonetary expansion after the economy recovered from the 1920 to 1921 depression.

The total money supply grew by $28 billion, a 61.8% increase between 1921 and 1928. Bank deposits increasedby 51.1%, savings and loan shares rose by 224.3%, and net life insurance policy reserves jumped by 113.8%. All this occurredafter the Federal Reserve cut required reserves to 3% in 1917.Gains in gold reserves via the Treasury and Fed were only $1.16 billion.

The Fed instigated the rapid expansion that preceded the collapse by increasing the money supply and keeping the interest rate low during the decade. Much of the surplus money supply growth inflated the stock market and real estate bubbles.

The Fed took the opposite course by cutting the money supply by nearly a third after the bubbles burstand the market crashed. This reduction causedsevere liquidity problems for many small banks and chokedoff hopes fora quick recovery.

The Fed's Tight Fist

As Bernanke noted in a November2002 address, bank panics were typically resolved within weeks before the Fed existed. Large private financial institutionswould loanmoney to the strongest smaller institutionsto maintain system integrity. That sort of scenario had occurred two decades earlier during the Panic of 1907.

Investment banker J.P. Morgan stepped in to rally Wall Street denizens to move significant amounts of capital to banks that were lacking funds when frenzied selling sent the NYSEspiraling downward and led to a bank run. Ironically, it was that panic that led the government to create the Federal Reserveto cut its reliance on individual financiers such asMorgan.

The heads of several New York banks had tried to instill confidence after Black Thursday by prominently purchasing large blocks of blue-chip stocks at above-market prices. These actions caused a brief rally on Friday but the panicked sell-offs resumed on Monday. The stock market has grown beyond the ability of such individual efforts in the decades since 1907. Only the Fed was big enough to prop up the U.S. financial system.

The Fed failed to do so with a cash injectionbetween 1929 and 1932. Itwatched the money supply collapse instead and let thousands of banks fail. This and a collapsing financial sector led to deflation and spurred the following depression. Banking laws at the time made it very difficult for institutions to grow and diversify enough to survive a massive withdrawal of deposits or a run on the bank.

The Fed's harsh reaction may have been the result of its fear that bailing out careless banks would encourage fiscal irresponsibility in the future. Some historians argue that the Fed createdthe conditions that caused the economy to overheatand that it then exacerbated an already direeconomic situation.

Hoover's Propped-Up Prices

Herbert Hoover has often been characterized as a "do-nothing" president but he took action after the crash occurred. He implemented three major changes between 1930 and 1932:

• An increase in federal spending by 42% that engaged in massive public works programs such as the Reconstruction Finance Corporation (RFC)
• Taxes to pay for new programs
• A ban on immigration in 1930 to keep low-skilled workers from flooding the labor market

Hoover was mainly concerned that wages would be cut following the economic downturn. He reasoned that prices had to stay high to ensure high paychecks in all industries. Consumers would have to pay more to keep prices high.

But the public was burned badly in the crash, leaving many people without the resources to spend lavishly on goods and services. Nor couldcompanies count on overseas trade because foreign nations weren't willing to buy overpriced American goods any more than Americans were.

U.S. Protectionism

This bleak reality forced Hoover to use legislationto prop up prices and wages by choking out cheaper foreign competition. Hesigned the Smoot-Hawley Tariff Act of 1930 into law following the tradition of protectionists and against the protests of more than a thousand of the nation's economists.

The act was initially intended to protect agriculturebut it swelled into a multi-industry tariff, imposing huge duties on more than 880 foreign products. Nearly three dozen countries retaliated and imports fell from $7 billion in 1929 to just $2.5 billion in 1932. International trade declined by 66% by 1934. Not surprisingly, economic conditions worsened worldwide.

Hoover's desire to maintain jobs and individual and corporate income levels was understandable but he encouraged businesses to raise wages, avoid layoffs, and keep prices high at a time when they naturally should have fallen. The United States suffered one to three years of low wages and unemployment, including previous cycles of recession/depression, before dropping prices led to a recovery.

The U.S. economy deterioratedfrom a recession to a depression when it was unable to sustain these artificial levels with global trade effectively cut off.

The New Deal

President Franklin Roosevelt promised massive change when he was elected in 1933. The New Deal he initiated was an innovative, unprecedented series of domestic programs and acts that were designed to bolster American businesses, reduce unemployment, and protect the public.

The New Deal was loosely based on Keynesian economics and the idea that the government could and should stimulate the economy. It set lofty goals to create and maintain the national infrastructure, full employment, and healthy wages. The government set about achieving these through price, wage, and even production controls.

Some economists claim that Roosevelt continued many of Hoover's interventions, just on a larger scale. He kept a rigid focus on price supports and minimum wagesand removedthe country fromthe gold standard,forbidding individuals to hoard gold coins and bullion. He banned monopolistic business practices and instituted dozens of new public works programs and other job-creation agencies.

The Roosevelt administration also paid farmers and ranchers to stop or cut back on production. One of the most heartbreaking conundrums of the period was the destruction of excess crops despite the need for thousands of Americans to access affordable food.

Federal taxes tripled between 1933 and 1940 to pay for these initiatives as well as new programs such as Social Security. These increases included hikes in excise taxes, personal income taxes, inheritance taxes, corporate income taxes, and an excess profits tax.

New Deal Success and Failure

The New Deal led to measurable results including financial system reform and stabilization and boosting public confidence. Roosevelt declared a bank holiday for an entire week in March 1933 to prevent institutional collapse due to panicked withdrawals. This was followed by a construction program for a network of dams, bridges, tunnels, and roads. These projects opened up federal work programs, employing thousands of people.

The economy showed some recovery but the rebound was far too weak for the New Deal's policies to be deemed successful in pulling America out of the Great Depression. Historians and economists disagree on the reason:

• Keynesians blame a lack of federal spending, saying that Roosevelt didn't go far enough in his government-centric recovery plans.
• Others claim that Roosevelt may have prolonged the Depression, just as Hoover did before him, by trying to spark immediate improvement instead of letting the economic/business cycle follow its usual two-year course of hitting bottom and then rebounding.

A study by two economists at the University of California, Los Angeles estimated that the New Deal extended the Great Depression by at least seven years. But it's possible that the relatively quick recovery that was characteristic of other post-depression recoveries may not have occurred as rapidly post-1929 because it was the first time the general public and not just the Wall Street elite lost large amounts in the stock market.

American economic historian Robert Higgs argued that Roosevelt's new rules and regulations came so fast and were so revolutionary that businesses became afraid to hire or invest. Philip Harvey, a professor of law and economics at Rutgers University, suggested that Roosevelt was more interested in addressing social welfare concerns than in creating a Keynesian-style macroeconomic stimulus package.

The Impact of World War II

The Great Depression appeared to end suddenly around 1941 to 1942 if we look at employment and GDP figures. This was the time when the United States entered World War II. The unemployment rate fell from eight million in 1940 to just over one million in 1943. However, more than 16 million Americans were conscripted to fight in the Armed Services. The real unemployment rate in the private sector grew during the war.

The standard of living declined due to wartime shortages caused by rationing and taxes rose dramatically to fund the war effort. Private investment dropped from $17.9 billion in 1940 to $5.7 billion in 1943 and total private-sector production fell by nearly 50%.

The notion that the warended the Great Depression is a broken window fallacy but the conflict did putthe United States on the road to recovery. The waropened international trading channels and reversed price and wage controls. Government demand opened up for inexpensive products and thedemand created a massive fiscal stimulus.

Private investments rose from $10.6 billion to $30.6 billion in the first 12 months after the war ended. The stock market broke into a bull run in a few short years.

The Bottom Line

The Great Depression was the result of an unlucky combination of factors including a flip-flopping Fed, protectionist tariffs, and inconsistently appliedgovernment interventionist efforts. This period could have been shortened or even avoided by a change in any one of these factors.

The debatecontinues as to whether the interventions were appropriate but many of the reforms from the New Deal exist to this day. They include Social Security, unemployment insurance, and agricultural subsidies. Theassumption that the federal government should act in times of national economic crisis has become strongly supported. This legacy is one of the reasons why the Great Depression is considered one of the seminal events in modern American history.
