When people ask "what year was the stock market crash," they’re usually looking for 1929. That's the big one. The grandfather of all financial nightmares. But honestly, if you're looking at a chart of the last century, that's like asking which year it rained.
The truth is, there isn't just one.
History is littered with these moments where everyone collectively loses their minds and decides to sell everything at the exact same time. It's kinda wild how it happens. One minute everyone is talkin' about "new plateaus" and "endless growth," and the next, they're watching their life savings evaporate on a flickering screen or a ticker tape.
Whether you're a history buff or just someone terrified that your 401(k) is about to pull a disappearing act, knowing these dates—and what actually triggered them—basically changes how you see money.
The Infamous 1929: When the Music Stopped
If we're being technical, the most famous answer to what year was the stock market crash is definitely 1929. This wasn't just a bad afternoon. It was a multi-day car wreck that ended the "Roaring Twenties" with a thud.
Most people point to October 29, 1929, also known as Black Tuesday.
But it really started earlier. On October 24 (Black Thursday), the market lost 11% at the opening bell. Bankers actually tried to huddle up and buy shares to prop the whole thing up. It worked... for about two days. Then Monday hit, the Dow dropped 13%, and Tuesday saw another 12% slide. By the time it was over, $14 billion in value had just vanished into thin air.

Imagine being there. Ticker machines couldn't even keep up with the volume. People were literally standing on the sidewalk outside the New York Stock Exchange, just staring at the building in total silence.
The crazy part? The market didn't hit its actual "bottom" until July 1932. By then, the Dow had lost roughly 89% of its value. You've gotta think about that—if you had $1,000 in the market, you were left with about $110. That's what triggered the Great Depression, and it's why 1929 is burned into the global psyche.
Black Monday 1987: The 22% Heart Attack
Fast forward to 1987.
This one is weird because the economy was actually doing okay. But on October 19, the Dow Jones Industrial Average plummeted 22.6% in a single day. To this day, it remains the largest one-day percentage drop in history.
Why did it happen?
- Program Trading: This was the first time computers really started calling the shots.
- The "Domino" Effect: Automatic sell orders triggered more sell orders, which triggered... well, you get it.
- Overvaluation: Stocks had been on a massive bull run since 1982, and things were getting a bit too "bubbly."
Unlike 1929, the 1987 crash didn't lead to a depression. The Federal Reserve jumped in, slashed interest rates, and basically told everyone to stay calm. It worked. The market actually recovered to its pre-crash levels within about two years. It's a great example of how a "crash" doesn't always mean the end of the world, even if it feels like it when you're watching the red numbers.

The 2008 Meltdown: Homes, Loans, and Lehman
When younger generations ask what year was the stock market crash, they’re usually thinking of 2008. This one felt different because it hit where people lived—literally.
The S&P 500 lost about half its value between October 2007 and March 2009.
The "official" crash moment most people remember is September 29, 2008. That was the day the Dow dropped 777.68 points after Congress initially rejected the bank bailout bill. The whole thing was built on a house of cards: subprime mortgages. Banks were giving loans to basically anyone with a pulse, bundling those loans into complex "securities," and selling them as safe investments.
When the housing bubble popped, the banks realized they were holding trillions in "toxic assets."
Lehman Brothers, a massive investment bank that had been around for 150 years, went bankrupt on September 15, 2008. That was the "oh crap" moment for the global financial system. Credit markets froze. Nobody would lend to anyone because they didn't know who was about to go broke next.

The most recent entry in the "what year was the stock market crash" hall of fame is 2020.

This was the fastest descent into a bear market in history. In February 2020, everything looked fine. By March, the world was locking down. The Dow had three of its worst days ever in a single month:
- March 9: Down 7.8% (Black Monday I)
- March 12: Down 10% (Black Thursday)
- March 16: Down 12.9% (Black Monday II)
It was pure, unadulterated panic. People weren't just worried about their portfolios; they were worried about a global plague. But here's the kicker—the recovery was just as fast. By August 2020, the S&P 500 was already hitting new all-time highs.
Why These Years Keep Happening
You'd think we'd learn, right?
But markets are driven by two very human emotions: greed and fear. When things are going up, everyone wants in (greed). When things start to slip, everyone wants out (fear).
Experts like Robert Shiller, who wrote Irrational Exuberance, point out that we often tell ourselves "this time is different." In 1929, it was the "New Era." In 1999, it was the "Internet Revolution." In 2007, it was "Real estate never goes down."
It’s always the same story with different characters.
Actionable Steps to Survive the Next One
Since we know another "what year was the stock market crash" candidate will eventually show up, you might as well be ready.
- Check Your Leverage: The people who got wiped out in 1929 and 2008 were usually those who borrowed money to invest. If you’re playing with the bank's money, a 10% drop can be a 100% loss.
- The 5-Year Rule: Never put money in the stock market that you need for rent or a mortgage in the next five years. Markets almost always recover, but they don't always do it on your timeline.
- Rebalance When You're Happy: When the market is soaring and you feel like a genius, that’s actually the time to sell a little bit of your winners and move them into something safer like bonds or cash.
- Ignore the Ticker: During the 2020 crash, the people who did the best were the ones who literally deleted their brokerage apps and went for a walk.
Understanding the history of these crashes isn't about predicting the next one—nobody can do that consistently. It's about realizing that volatility is the "price of admission" for the long-term gains the market offers. 1929, 1987, 2008, 2020—they all feel like the end when they're happening, but history shows they're usually just painful resets before the next climb.
