The Making of the “Big Four” Banking Oligopoly in One Chart
The Banking Oligopoly in One Chart
The “Big Four” retail banks in the United States collectively hold 45% of all customer bank deposits for a total of $4.6 trillion.
The fifth biggest retail bank, U.S. Bancorp, is nothing to sneeze at, either. It’s got 3,151 banking offices and employs 65,000 people. However, it still pales in comparison with the Big Four, holding only a mere $271 billion in deposits.
Today’s visualization looks at consolidation in the banking industry over the course of two decades. Between 1990 and 2010, eventually 37 banks would become JP Morgan Chase, Bank of America, Wells Fargo, and Citigroup.
Of particular importance to note is the frequency of consolidation during the 2008 Financial Crisis, when the Big Four were able to gobble up weaker competitors that were overexposed to subprime mortgages. Washington Mutual, Bear Stearns, Countrywide Financial, Merrill Lynch, and Wachovia were all acquired during this time under great duress.
The Big Four is not likely to be challenged anytime soon. In fact, the Federal Reserve has noted in a 2014 paper that the number of new bank charters has basically dropped to zero.
From 2009 to 2013, only seven new banks were formed.
“This dramatic reduction in new bank charters could be a concern for policymakers, if as some suggest, the decline has been caused by increased regulatory burden imposed in response to the financial crisis,” the authors of the Federal Reserve paper write.
Competition from small banks has dried up as a result. A study by George Mason University found that over the last 15 years, the amount of small banks in the country has decreased by -28%.
Big banks, on the other hand, are doing relatively quite well. There are now 33% more big banks today than there were in 2000.

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 is different than the 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.
