10 Financial Crises That Changed the World
History doesn't repeat, but it rhymes.
These are the 10 loudest rhymes in financial history — from tulip bulbs to subprime mortgages, scored by severity, contagion, and whether we actually learned anything.

Tulip Mania
1637
The Trigger
Dutch speculators bid tulip bulb prices to absurd levels — a single Semper Augustus bulb sold for more than a canal house in Amsterdam. Futures contracts traded on bulbs that hadn't even been planted yet. When buyers stopped showing up to auctions in February 1637, the entire market collapsed overnight.
The Damage
Bulb prices fell ~99% in weeks. Fortunes were wiped out. Contracts became unenforceable. The Dutch economy stalled, though the broader impact was limited to speculators and adjacent industries.
The Aftermath & Reforms
The Dutch government eventually voided most tulip contracts, letting buyers off the hook for pennies on the guilder. No formal regulation followed — the concept of a 'speculative bubble' didn't even exist yet. It took decades for the tulip trade to normalize.
What We Learned
Asset prices can completely disconnect from intrinsic value when speculation takes over. The OG bubble taught us that 'this time is different' is the most expensive sentence in any language.
What We Ignored
We kept doing it. Every single time. The South Sea Bubble happened 83 years later. We are incapable of learning this lesson permanently.
If you'd invested at the bottom: There was no stock market to buy, but if you'd bought Amsterdam real estate in 1637 with the money you didn't spend on tulips, your descendants would own half the canal district.
South Sea Bubble
1720
The Trigger
The South Sea Company was granted a monopoly on British trade with South America — trade that barely existed. The company took on the national debt in exchange for shares, then pumped the stock through false promises and insider manipulation. Share price rose 10x in months. Even Isaac Newton invested. When insiders started selling, the scheme unraveled.
The Damage
South Sea shares fell from £1,050 to £100 — a 90%+ collapse. Newton lost £20,000 (roughly $4.6M in today's money). He famously said: 'I can calculate the motion of heavenly bodies, but not the madness of people.' Thousands of investors were ruined.
The Aftermath & Reforms
Parliament passed the Bubble Act of 1720, restricting the formation of joint-stock companies. Several directors were arrested and their estates confiscated. Robert Walpole, who helped clean up the mess, became Britain's first de facto Prime Minister.
What We Learned
When the smartest person in the room loses money, the bubble is real. Government-backed schemes can be just as fraudulent as private ones. Insider selling is the only signal that matters.
What We Ignored
Newton — literally the smartest human alive — couldn't resist FOMO. If gravity's discoverer can't resist a bubble, what chance do the rest of us have?
If you'd invested at the bottom: If you'd bought British government consols (bonds) at the bottom of the panic in 1720, they paid reliable 3-4% annual returns for the next two centuries. Boring, but your great-great-grandchildren would thank you.
Panic of 1907
1907
The Trigger
A failed attempt to corner the copper market triggered a cascade of bank runs across New York City. Trust companies — the shadow banks of the era — had made risky loans and had no lender of last resort. The New York Stock Exchange fell nearly 50% from its 1906 peak. Credit froze. Banks started failing.
The Damage
NYSE dropped ~50%. Multiple banks and trust companies failed. Unemployment surged. GDP contracted sharply. The crisis spread from Wall Street to Main Street as credit evaporated across the country.
The Aftermath & Reforms
J.P. Morgan — the actual human being, not the bank — personally organized a bailout. He locked the nation's top bankers in his library and refused to let them leave until they pledged money to stabilize the system. One man bailed out America. Congress was so embarrassed that a private citizen had to save the financial system that they created the Federal Reserve in 1913.
What We Learned
A financial system without a lender of last resort is a financial system one bad bet away from collapse. The birth of central banking was a direct consequence of this crisis.
What We Ignored
We created the Fed, then spent the next century arguing about whether the Fed should exist. Also, 'too interconnected to fail' was already obvious in 1907 — we just kept pretending it wasn't.
If you'd invested at the bottom: $10,000 invested in the DJIA at the 1907 bottom would have grown to roughly $45,000 by 1929 — a 350% return in 22 years. Of course, then 1929 happened.
Great Depression / 1929 Crash
1929
The Trigger
The Roaring Twenties saw massive margin-fueled speculation. By 1929, investors were borrowing 90 cents on every dollar to buy stocks. When the market hiccuped on Black Thursday (Oct 24), margin calls cascaded. Black Tuesday (Oct 29) saw 16 million shares traded — a record that stood for decades. But the crash was just the beginning. Bank failures, the Smoot-Hawley tariff, and catastrophic Federal Reserve policy errors turned a market crash into a decade-long depression.
The Damage
The Dow fell 89% from its 1929 peak to its 1932 trough — from 381 to 41. US unemployment hit 25%. GDP contracted by 30%. 9,000 banks failed. Global trade collapsed by 65%. It was the worst economic disaster in modern history, and it wasn't close.
The Aftermath & Reforms
FDR's New Deal created Social Security, the SEC, the FDIC, Glass-Steagall (separating commercial and investment banking), and the modern regulatory state. The recovery took a full decade and arguably wasn't complete until World War II spending kicked in.
What We Learned
Margin lending without limits is gasoline on a fire. Central banks must act as lenders of last resort during a crisis (the Fed's passive tightening made everything worse). And deposit insurance prevents bank runs.
What We Ignored
Glass-Steagall was repealed in 1999. Margin lending came back. 'The market always goes up' became gospel again. We literally un-learned the most expensive lesson in financial history.
If you'd invested at the bottom: $10,000 invested in the DJIA at the July 1932 bottom would be worth approximately $55 million today (including dividends reinvested). The single greatest buying opportunity in the history of capital markets.
1973 Oil Crisis
1973
The Trigger
OPEC declared an oil embargo against the United States and other nations supporting Israel in the Yom Kippur War. Oil prices quadrupled from $3 to $12 per barrel almost overnight. Gas stations ran dry. The post-WWII assumption of cheap, abundant energy — the foundation of the entire Western economic model — shattered.
The Damage
The S&P 500 fell ~48% from January 1973 to October 1974. US GDP contracted. Unemployment doubled. Inflation hit double digits, creating 'stagflation' — simultaneous recession and inflation that wasn't supposed to be possible according to prevailing economic theory.
The Aftermath & Reforms
The US created the Strategic Petroleum Reserve and the Department of Energy. Speed limits were set to 55 mph nationally. CAFE fuel economy standards were born. The crisis ended the Bretton Woods era of cheap energy and stable growth, ushering in the volatile 1970s.
What We Learned
Energy dependence is a national security risk, not just an economic one. Supply shocks can cause inflation and recession simultaneously — Keynesian economics had no playbook for stagflation.
What We Ignored
We're still dependent on foreign oil (or the geopolitical stability of oil-producing regions). The 'energy independence' goal from 1973 took 50 years to even approach.
If you'd invested at the bottom: $10,000 invested in the S&P 500 at the October 1974 bottom would be worth approximately $2.4 million today. That's a 240x return for buying when everyone thought the world was ending.
Black Monday
1987
The Trigger
On October 19, 1987, the Dow Jones fell 22.6% in a single day — the largest one-day percentage drop in history, a record that still stands. The catalyst was a combination of overvaluation, rising interest rates, and 'portfolio insurance' — computer-driven hedging strategies that automatically sold stocks as prices fell, creating a doom loop. The machines sold because prices fell, and prices fell because the machines sold.
The Damage
22.6% gone in one day. $500 billion in market value evaporated between 9:30 AM and 4:00 PM. Markets around the world cascaded: Hong Kong fell 45%, Australia 42%, the UK 26%. It was the first truly global, technology-amplified crash.
The Aftermath & Reforms
The NYSE introduced circuit breakers — automatic trading halts when the market falls too quickly. The Fed, under new chairman Alan Greenspan, flooded the system with liquidity. The market recovered all its losses within two years. Greenspan's intervention created the template (and the moral hazard) for every Fed bailout since.
What We Learned
Algorithmic trading can create feedback loops that amplify crashes beyond what fundamentals justify. Circuit breakers and Fed intervention became the new playbook. Also: the market can lose a quarter of its value in six hours.
What We Ignored
The 'Greenspan Put' — the expectation that the Fed will always bail out the market — encouraged increasingly reckless risk-taking for the next three decades. We traded one problem for a bigger one.
If you'd invested at the bottom: $10,000 invested in the S&P 500 on October 20, 1987 (the day after Black Monday) would be worth approximately $350,000 today. The fastest recovery in history up to that point.
Asian Financial Crisis
1997
The Trigger
Thailand ran out of foreign currency reserves trying to defend the baht's peg to the US dollar. When the peg broke on July 2, 1997, hot money fled across Southeast Asia like a contagion. Currency speculators (most famously, hedge funds) attacked one Asian currency after another. Indonesia, South Korea, Malaysia, and the Philippines all saw their currencies and stock markets collapse in sequence.
The Damage
Thai baht lost 50% of its value. Indonesian rupiah fell 80%. The South Korean won dropped 50%. Stock markets across Asia fell 40-70%. Indonesia's GDP contracted 13% in a single year. The crisis pushed 100+ million people below the poverty line across the region.
The Aftermath & Reforms
The IMF provided $118 billion in bailout packages with severe austerity conditions — conditions that many economists now argue made the crisis worse. Asian countries responded by building massive foreign currency reserves (China's $3 trillion+ reserve is a direct legacy). Malaysia's Mahathir imposed capital controls and was ridiculed at the time but recovered faster than IMF-program countries.
What We Learned
Currency pegs without adequate reserves are time bombs. Hot money flows create fragility. IMF austerity during a crisis can deepen the recession. And financial contagion can spread across borders faster than anyone expects.
What We Ignored
The exact same hot-money-to-crisis pattern repeated in 1998 (Russia), 2001 (Argentina), and 2018 (Turkey). Capital flows remain the most dangerous force in global finance.
If you'd invested at the bottom: $10,000 invested in the Thai SET index at its January 1998 bottom would be worth roughly $55,000 today. South Korean KOSPI investors did even better — roughly $80,000.
Dot-Com Bubble
2000
The Trigger
The internet was going to change everything (it did), so every company with a .com in its name was worth billions (they weren't). Pets.com raised $82 million in an IPO and went bankrupt 268 days later. Webvan burned through $800 million trying to deliver groceries. TheGlobe.com rose 606% on its first day of trading. The Nasdaq peaked at 5,048 on March 10, 2000, and the music stopped.
The Damage
The Nasdaq fell 78% from peak to trough — from 5,048 to 1,114. $5 trillion in market value vanished. Pets.com, Webvan, Kozmo, Boo.com, and hundreds of other companies evaporated entirely. Even Amazon fell 93%, from $107 to $7. Cisco, the backbone of the internet, fell 86% and still hasn't recovered its 2000 price (adjusted for inflation).
The Aftermath & Reforms
Sarbanes-Oxley Act tightened financial reporting requirements. The SEC cracked down on analyst conflicts of interest (Wall Street banks had been publishing 'buy' ratings on companies their investment banking arms were taking public). The survivors — Amazon, Google, eBay — went on to become the most valuable companies in history.
What We Learned
Revenue matters. Business models matter. 'Eyeballs' and 'first-mover advantage' are not substitutes for actually making money. The technology was transformative; the valuations were insane.
What We Ignored
Two decades later, we did the exact same thing with crypto, SPACs, and unprofitable growth stocks in 2021. WeWork, Theranos, FTX — the Pets.coms of the 2020s. We learned nothing.
If you'd invested at the bottom: $10,000 invested in the Nasdaq at the October 2002 bottom would be worth approximately $180,000 today. $10,000 in Amazon at $7 in 2001 would be worth roughly $2.7 million.
2008 Global Financial Crisis
2008
The Trigger
Banks packaged subprime mortgages into complex securities (CDOs), got them rated AAA by compliant rating agencies, and sold them to investors worldwide. When housing prices stopped rising, the defaults cascaded. Bear Stearns collapsed in March. Lehman Brothers filed for bankruptcy on September 15 — the largest bankruptcy in US history. AIG, which had insured $440 billion in these securities, needed a $182 billion government bailout. The entire global financial system froze.
The Damage
The S&P 500 fell 57% from peak to trough. US unemployment hit 10%. 8.7 million jobs were lost. 3.8 million foreclosures in 2010 alone. Global GDP contracted for the first time since WWII. The total cost of the crisis is estimated at $22 trillion in lost economic output. 'Too big to fail' entered the lexicon.
The Aftermath & Reforms
Dodd-Frank Wall Street Reform Act. The Volcker Rule. Basel III capital requirements. Stress testing. The Fed dropped interest rates to zero and invented quantitative easing — buying $4.5 trillion in assets. The government bailout of banks (TARP) was $700 billion. AIG got $182 billion. The auto industry got $80 billion. And the people who lost their homes got nothing.
What We Learned
Complex financial instruments can hide risk so effectively that even the people selling them don't understand what they own. Rating agencies have conflicts of interest. Deregulation without oversight creates systemic risk. And when the system breaks, the taxpayer pays.
What We Ignored
Not a single major bank CEO went to jail. The banks that caused the crisis got bigger after the crisis (JPMorgan absorbed Bear Stearns and Washington Mutual). 'Too big to fail' became 'too big to jail.' The moral hazard is larger now than it was in 2007.
If you'd invested at the bottom: $10,000 invested in the S&P 500 at the March 2009 bottom would be worth approximately $95,000 today. The greatest bull market in history was born from the ashes of the worst financial crisis since the Depression.
COVID Crash
2020
The Trigger
A novel coronavirus shut down the global economy in real-time. On March 9, 2020, the Dow fell 2,014 points. On March 12, it fell 2,352 points. On March 16, it fell 2,997 points — the largest single-day point drop in history. Circuit breakers triggered four times in ten days. The VIX hit 82 — higher than 2008. Oil futures went negative for the first time in history, meaning sellers were paying buyers to take oil off their hands.
The Damage
The S&P 500 fell 34% in 23 trading days — the fastest bear market in history. US unemployment spiked from 3.5% to 14.7% in two months. Global GDP contracted 3.1%. 22 million Americans filed for unemployment in four weeks. Airlines, hotels, restaurants, and retail were devastated.
The Aftermath & Reforms
The Fed cut rates to zero and launched unlimited QE. Congress passed $5 trillion in stimulus — PPP loans, stimulus checks, enhanced unemployment. The market bottomed on March 23 and recovered all losses by August. The recovery was as unprecedented as the crash: the Nasdaq hit all-time highs by June. But the stimulus also contributed to the worst inflation in 40 years, leading to the aggressive rate hikes of 2022-2023.
What We Learned
Governments and central banks can prevent a depression if they act fast enough and big enough. The 2020 response was everything the 1929 response wasn't — immediate, massive, coordinated. It worked. It also proved that pandemic risk was not priced into any model anywhere.
What We Ignored
The speed of the recovery convinced a generation of investors that 'stocks only go up' and 'the Fed will always save us.' That belief fueled the meme stock mania, the crypto bubble, and the 2021 SPAC explosion. Every bailout plants the seed of the next crisis.
If you'd invested at the bottom: $10,000 invested in the S&P 500 on March 23, 2020 would be worth approximately $26,000 today. $10,000 in Tesla at its March 2020 low of ~$72 would be worth roughly $350,000.

Glen's Take
I've studied every one of these crises obsessively, and the pattern is so consistent it's almost insulting. The cycle goes: innovation creates genuine value, speculation inflates it beyond recognition, insiders cash out, the music stops, regular people lose everything, governments create new regulations, Wall Street finds a way around them, and we do it all again 10-15 years later.
The most interesting thing on this list isn't the crashes — it's the “if you'd invested at the bottom” numbers. $10,000 at the 1932 bottom is $55 million today. $10,000 in Amazon during the dot-com bust is $2.7 million. The pattern is always the same: the best time to invest is when it feels the most terrifying.
But here's the part nobody tells you: buying at the bottom requires two things that are almost mutually exclusive — having cash when everyone is selling, and having the conviction to deploy it when the world feels like it's ending. The people who buy at the bottom aren't brave. They're just prepared.
The next crisis is coming. It always is. The question isn't whether — it's whether you'll be a buyer or a seller when it arrives. History is loudly, repeatedly, screaming the answer at you.

What was the worst financial crisis in history?
By almost every metric — market decline, unemployment, duration, and global impact — the Great Depression (1929-1932) was the worst financial crisis in history. The Dow fell 89%, unemployment hit 25%, GDP contracted 30%, and 9,000 banks failed. The recovery took a full decade and wasn't truly complete until World War II. The 2008 Global Financial Crisis is the runner-up, with the S&P 500 falling 57% and an estimated $22 trillion in lost economic output.
What caused the 2008 financial crisis?
The 2008 crisis was caused by a combination of factors: banks made risky subprime mortgage loans, packaged them into complex securities (CDOs), got them rated AAA by conflicted rating agencies, and sold them worldwide. When housing prices fell, the defaults cascaded through the system. Lehman Brothers' bankruptcy in September 2008 triggered a global financial panic. The crisis was enabled by deregulation, inadequate oversight, and the belief that housing prices could never fall nationally.
How often do financial crises happen?
Major financial crises happen roughly every 10-15 years, though the pattern is irregular. The 20th and 21st centuries saw major crises in 1907, 1929, 1973, 1987, 1997, 2000, 2008, and 2020. The intervals range from 3 years (2000 to 2008's roots) to 42 years (1929 to 1973). The common thread isn't timing — it's that each crisis arrives precisely when everyone has decided the last one could never happen again.
What was Black Monday and why did it happen?
Black Monday (October 19, 1987) saw the Dow Jones Industrial Average fall 22.6% in a single trading day — the largest one-day percentage decline in history. The crash was driven by a combination of overvaluation, rising interest rates, and 'portfolio insurance' — computer-driven trading strategies that automatically sold stocks as prices fell, creating a feedback loop. It was the first crash amplified by algorithmic trading and led to the creation of circuit breakers.
If you invested at the bottom of every crash, how rich would you be?
Spectacularly rich. $10,000 at the 1932 bottom would be ~$55 million today. $10,000 at the 2009 bottom would be ~$95,000. $10,000 in Amazon at the 2001 dot-com bottom would be ~$2.7 million. The pattern is consistent: the best buying opportunities in history happen when it feels most terrifying to invest. The catch is that 'the bottom' is only obvious in hindsight — nobody rings a bell.
