The World’s Most Famous Case of Deflation
The World’s Most Famous Case of Deflation (Part 1 of 2)
The Money Project is an ongoing collaboration between Visual Capitalist and Texas Precious Metals that seeks to use intuitive visualizations to explore the origins, nature, and use of money.
The Great Depression was the most severe economic depression ever experienced by the Western world.
It was during this troubled time that the world’s most famous case of deflation also happened. The resulting aftermath was so bad that economic policy since has been chiefly designed to prevent deflation at all costs.
Setting the Stage
The transition from wartime to peacetime created a bumpy economic road after World War I.
Growth has hard to come by in the first years after the war, and by 1920-21 the economy fell into a brief deflationary depression. Prices dropped -18%, and unemployment jumped up to 11.7% in 1921.
However, the troubles wouldn’t last. During the “Roaring Twenties”, economic growth picked up as the new technologies like the automobile, household appliances, and other mass-produced products led to a vibrant consumer culture and growth in the economy.
More than half of the automobiles in the nation were sold on credit by the end of the 1920s. Consumer debt more than doubled during the decade.
While GDP growth during this period was extremely strong, the Roaring Twenties also had a dark side. Income inequality during this era was the highest in American history. By 1929, the income of the top 1% had increased by 75%. Income for the rest of people (99%) increased by only 9%.
The Roaring Twenties ended with a bang. On Black Thursday (Oct 24, 1929), the Dow Jones Industrial Average plunged 11% at the open in very heavy volume, precipitating the Wall Street crash of 1929 and the subsequent Great Depression of the 1930s.
The Cause of the Great Depression
Economists continue to debate to this day on the cause of the Great Depression. Here’s perspectives from three different economic schools:
Keynesian:
John Maynard Keynes saw the causes of the Great Depression hinge upon a lack of aggregate demand. This later became the subject of his most influential work, The General Theory of Employment, Interest, and Money, which was published in 1936.
Keynes argued that the solution was to stimulate the economy through some combination of two approaches:
1. A reduction in interest rates (monetary policy), and
2. Government investment in infrastructure (fiscal policy).
“The difficulty lies not so much in developing new ideas as in escaping from old ones.” – John Maynard Keynes
Monetarist:
Monetarists such as Milton Friedman viewed the cause of the Great Depression as a fall in the money supply.
Friedman and Schwartz argue that people wanted to hold more money than the Federal Reserve was supplying. As a result, people hoarded money by consuming less. This caused a contraction in employment and production since prices were not flexible enough to immediately fall.
“The Great Depression, like most other periods of severe unemployment, was produced by government mismanagement rather than by any inherent instability of the private economy.” ― Milton Friedman
Austrian:
Austrian economists argue that the Great Depression was the inevitable outcome of the monetary policies of the Federal Reserve during the 1920s.
In their opinion, the central bank’s policy was an “easy credit policy” which led to an unsustainable credit-driven boom.
“Any increase in the relative size of government in the economy, therefore, shifts the societal consumption-investment ratio in favor of consumption, and prolongs the depression.” – Murray Rothbard
The Great Depression and Deflation
Between 1929 and 1932, worldwide GDP fell by an estimated 15%.
Deflation hit.
Personal income, tax revenue, profits and prices plunged. International trade fell by more than 50%. Unemployment in the U.S. rose to 25% and in some countries rose as high as 33%.
These statistics were only the tip of the iceberg. Learn about the full effects, the stories, and the recovery from the Great Depression in Part 2.

The Money Project aims to use intuitive visualizations to explore ideas around the very concept of money itself. Founded in 2015 by Visual Capitalist and Texas Precious Metals, the Money Project will look at the evolving nature of money, and will try to answer the difficult questions that prevent us from truly understanding the role that money plays in finance, investments, and accumulating wealth.

3 Reasons Why AI Enthusiasm Differs from the Dot-Com Bubble
Valuations are much lower than they were during the dot-com bubble, but what else sets the current AI enthusiasm apart?

3 Reasons Why AI Enthusiasm Differs from the Dot-Com Bubble
Artificial intelligence, like the internet during the dot-com bubble, is getting a lot of attention these days. In the second quarter of 2023, 177 S&P 500 companies mentioned “AI” during their earnings call, nearly triple the five-year average.
Not only that, companies that mentioned “AI” saw their stock price rise 13.3% from December 2022 to September 2023, compared to 1.5% for those that didn’t.
In this graphic from New York Life Investments, we look at current market conditions to find out if AI could be the next dot-com bubble.
Comparing the Dot-Com Bubble to Today
In the late 1990s, frenzied optimism for internet-related stocks led to a rapid rise in valuations and an eventual market crash in the early 2000s. By the time the market hit rock bottom, the tech-heavy Nasdaq 100 Index had dropped 82% from its peak.
The growing enthusiasm for AI has some concerned that it could be the next dot-com bubble. But here are three reasons that the current environment is different.
1. Valuations Are Lower
Stock valuations are much lower than they were at the peak of the dot-com bubble. For example, the forward price-to-earnings ratio of the Nasdaq 100 is significantly lower than it was in 2000.
Date | Forward P/E Ratio |
---|---|
March 2000 | 60.1x |
November 2023 | 26.4x |
Lower valuations are an indication that investors are putting more emphasis on earnings and stocks are less at risk of being overvalued.
2. Investors Are More Hesitant
During the dot-com bubble, flows to equity funds increased by 76% from 1999 to 2000.
Year | Combined ETF and Mutual Fund Flows to Equity Funds |
---|---|
1997 | $231B |
1998 | $163B |
1999 | $200B |
2000 | $352B |
2001 | $63B |
2002 | $14B |

In contrast, equity fund flows have been negative in 2022 and 2023.
Year | Combined ETF and Mutual Fund Flows to Equity Funds |
---|---|
2021 | $295B |
2022 | -$54B |
2023* | -$137B |
Source: Investment Company Institute
*2023 data is from January to September.
Based on fund flows, investors appear hesitant of stocks, rather than overly exuberant.
3. Companies Are More Established
Leading up to the internet bubble, the number of technology IPOs increased substantially.
Year | Number of Technology IPOs | Median Age |
---|---|---|
1997 | 174 | 8 |
1998 | 113 | 7 |
1999 | 370 | 4 |
2000 | 261 | 5 |
2001 | 24 | 9 |
2002 | 20 | 9 |
Many of these companies were relatively new and, at the peak of the bubble in 2000, only 14% of them were profitable.
In recent years, there have been far fewer tech IPOs as companies wait for more positive market conditions. And those that have gone public, the median age is much higher.
Year | Number of Technology IPOs | Median Age |
---|---|---|
2020 | 48 | 12 |
2021 | 126 | 12 |
2022 | 6 | 15 |
Ultimately, many of the companies benefitting from AI are established companies that are already publicly traded. New, unproven companies are much less common in public markets.
Navigating Modern Tech Amid Dot-Com Bubble Worries
Valuations, equity flows, and the shortage of tech IPOs all suggest that AI isn’t shaping up to be the next dot-com bubble.
However, risk is still present in the market. For instance, only 33% of tech companies that went public in 2022 were profitable. Investors can help manage their risk by keeping a diversified portfolio rather than choosing individual stocks.
