What We’ve Learned From 150 Years of Stock Market Crashes

Not even two years later, the stock market experienced a worse downturn: The market took 4 times as long (18 months) to recover from the crash of December 2021, spurred by the Russia-Ukraine war, intense inflation, and supply shortages.

So, with these recent market crashes behind us, what have we learned?

1. It’s impossible to predict how long a stock market recovery will take.
2. If you don’t panic and sell your stock holdings when the market crashes, you will be rewarded in the long run.

The covid crash and the Ukraine/inflation downturn may be the freshest memories, but these lessons also ring true when it comes to all other historical market crashes: Though they had varying lengths and levels of severity, the market always recovered and went on to new highs.

Here’s what we’ve learned from the market declines of the past 150 years.

How Frequent Are Market Crashes?

The number of market crashes depends on how far back we go in history and how we identify them.

Here, we turn to data that former Morningstar Director of Research Paul Kaplan compiled for the book Insights into the Global Financial Crisis. Kaplan’s data includes monthly US stock market returns going back to January 1886 and annual returns over the period from 1871-1885.

In the chart below, each bear-market episode is indicated with a horizontal line, which starts at the episode’s peak cumulative value and ends when the cumulative value recovers to the previous peak. (Note that we use the term “market crash” interchangeably with bear market, which is generally defined as a decline of 20% or more.)

When you incorporate the effect of inflation, one dollar (in 1870 US dollars) invested in a hypothetical US stock market index in 1871 would have grown to $31,255 by the end of January 2025.

The substantial growth of that $1 highlights the enormous benefits of staying invested for the long term.

Still, it was far from a steady increase over that period. There were 19 market crashes along the way, with varying levels of severity. Some of the most severe market crashes have included:

• The Great Depression, which began with the crash of 1929. This 79% stock market loss was the worst drop of the past 150 years.

• The Lost Decade, which included both the dot-com bubble burst and the Great Recession. Though the market began recovering after the dot-com bubble burst, it didn’t climb back to its previous level before the crash of 2007-09. It didn’t reach that level until May 2013—more than 12 years after the initial crash. This period, the second-worst drop of the past 150 years, ultimately included a stock market loss of 54%.

• Inflation, Vietnam, and Watergate, which began in early 1973 and ultimately led to a stock market decline of 51.9%. Factors that contributed to this bear market include civil unrest related to the war in Vietnam and the Watergate scandal, in addition to high inflation from the OPEC oil embargo. This market downturn is particularly relevant to today’s environment, given issues like the recent inflation surge and the Russia-Ukraine and Israel-Hamas wars.

These examples demonstrate the frequency of market crashes. Though these events are significant at the moment, they are indeed regularly occurring events that happen approximately once a decade.

How to Measure the Pain of a Market Crash

How do you evaluate a market crash’s severity? That’s what Kaplan’s “pain index” measures. This framework considers both the degree of the decline and how long it took to get back to the prior level of cumulative value.

Here’s how it works: The pain index is the ratio of the area between the cumulative value line and the peak-to-recovery line, compared with that area for the worst market decline since 1870. That is, the crash of 1929/first part of the Great Depression has a pain index of 100%, and the other market crashes’ percentages represent how closely they matched that level of severity.

For example, consider that the market suffered a 22.8% drop around the Cuban missile crisis. The crash of 1929 led to a 79% drop, which is 3.5 times greater. That’s already significant, but also consider that the market took four and a half years to recover after that trough, while it took less than a year to recover after the trough of the Cuban missile crisis. So, taking this time frame into account, the pain index conveys that the first part of the Great Depression was 28.2 times worse than the Cuban missile crisis downturn.

The table below lists the bear markets of the past 150 years, sorted by the severity of market decline, and including its pain index.

As you can see, the market downturn of December 2021 (resulting from the Russia-Ukraine war, intense inflation, and supply shortages) ranks 11th on this list. By comparing this market crash to the other ones on the table, we see that the 28.5% stock market decline over that nine-month period was more painful for the stock market than the Cuban missile crisis and several downturns of the late 1800s/early 1900s.

And the covid crash of March 2020 was actually the least painful of these 19 crashes, due to the quick subsequent recovery. Though the downturn was sharp and severe (a 19.6% decline over roughly a month), the stock market ultimately recovered to its previous level a mere four months later.

5 Most Severe Market Crashes of the Past 150 Years

To better evaluate the impact of some of the most severe downturns of the past 150 years, let’s follow the path of $100 at the beginning of each market crash.

The market ultimately recovered from the Great Recession in May 2013, but still to come was the covid market crash and the downturn of late 2021.

There were also several shorter, less severe market declines over these 150 years. Consider the Rich Man’s Panic, caused by President Theodore Roosevelt’s attempt to break up large companies. Or the Baring Brothers Crisis: Barings Bank’s numerous investments in Argentina suffered when the nation faced a coup in 1891.

Yet even with those blips along the way, $100 invested at the beginning of the new millennium would be worth more than $300 as of January 2025. If that $100 had been invested back in 1870, it would be worth $3,125,500 today.

Lessons Learned About Navigating Stock Market Volatility

So, what does this history tell us about navigating volatile markets? Mainly, that they’re worth navigating.

After a couple stressful months in the first half of 2020, the markets recovered—just as they did after a 79% decline in the early 1930s. And that’s the point: Market crashes always feel scary when they happen, but there’s no way to know in the moment if you’re encountering a minor correction or looking down the barrel of the next Great Depression.

Still, even if you are looking down the barrel of the next Great Depression, history shows us that the market eventually recovers.

But since the path to recovery is so uncertain, the best way to be prepared is by owning a well-diversified portfolio that fits your time horizon and risk tolerance. Investors who stay invested in the market in the long run will reap rewards that make the turmoil worthwhile.
