We Study Billionaires – TIP784: History's Biggest Market Bubbles w/ Clay Finck

Release Date: January 16, 2026
Host: Clay Finck
Source Book: Devil Take the Hindmost by Edward Chancellor

Overview of the Episode

In this episode, Clay Finck explores three of history’s most notorious market bubbles: the South Sea Bubble (1720), Railway Mania (1845), and the Japanese Stock Market and Property Bubble (1989). Drawing mainly from Edward Chancellor’s seminal book Devil Take the Hindmost, the episode dissects each bubble’s origins, the psychology that fueled them, and the severe economic consequences left in their wake. The overarching theme is how the study of these episodes helps investors recognize—and avoid—similar speculative traps in the future.

Key Discussion Points & Insights

1. The Nature and Role of Speculation

• Speculation vs. Investment: Finck explains how speculation lies on a spectrum and is integral to market progress, but at extremes leads to bubbles and ruin.
  • “All of us to some degree actually are speculators... For an economy to thrive, you need entrepreneurs who are willing to take these risks and dare I say, speculate with their own self-interest in mind.” (04:00)
• Quotes on Speculation:
  • Paraphrasing Keynes: “The market can stay irrational longer than you can stay solvent.” (00:47)
  • Fred Schwed: “Speculation is an effort, probably unsuccessful, to turn a little money into a lot. Investment is an effort which should be successful to prevent a lot of money becoming a little.” (09:55)

2. The South Sea Bubble (1720)

[06:43–28:11]

Origins & Mechanics

• Founded to absorb British government debt, South Sea Company promised profits from trade monopolies but actually relied on financial games and perpetually rising stock prices.
• Widespread involvement: even the King, government officials, and premier banks participated.

Bubble Dynamics

• Public frenzy was fueled by access to leverage (buying on margin) and deliberate obfuscation by company leadership.
  • “The more confusion the better.” (16:23, paraphrasing John Blunt’s approach)
• Shares soared from £128 to over £1000 in months.

Collapse

• Authorities tried to curb competing “bubble companies,” inadvertently causing a crash.
• In mere weeks, prices fell 75%; key societal figures went bankrupt, including Sir Isaac Newton, who lamented:
  • “I can calculate the motions of the heavenly bodies, but not the madness of the people.” (24:54)
• Key Lesson: Government complicity magnified the disaster. Publicly available information pointed to a bubble, but mass psychology prevailed.

Notable Quotes

• “Government officials were bribed in helping facilitate the scheme and would get shares handed to them. So they were financially incentivized to fuel the bubble as much as possible and not put these guardrails in place...” (25:50)
• “Investors buying at a thousand pounds a share... were not behaving rationally, and were hoping for a greater fool to pay an even higher price in the near future rather than purchasing based on fundamentals.” (27:45)

3. Railway Mania (1845)

[28:15–42:31]

Context and Build-up

• Appearing in the wake of canal speculation, the railway boom was powered by genuine technological innovation, but excessive optimism ensued.
• “Inventions and novelties have always excited speculators… but the advent of railways… represented a far more significant change in the life of mankind.” (29:44)

Speculative Excess

• The railway king, George Hudson, was both a symbol and driver of the mania.
• Use of leverage, misleading dividend payments, and self-dealing by insiders were rampant.
  • “Hudson remained a hero... as he had literally gone from rags to riches and was a symbol of the get-rich-quick mentality...” (38:27)
• Newspapers were loaded with rail prospectuses; masses engaged in risky speculation exceeding their means.

Crash and Aftermath

• Bank of England raised rates: the speculative structure imploded.
• Middle class families suffered enormous losses; bankruptcies and lawsuits multiplied; value of railway shares collapsed by 85% from the peak.
• Post-crash inquiry exposed rampant fraud and creative accounting.
  • “It was discovered that he [Hudson] had been propping up dividends by using investor capital and not the profits of the underlying business…” (40:30)

Notable Quote

• Bill Gates (reflecting on technology bubbles):
  • “Gold rushes tend to encourage impetuous investments. A few will pay off, but when the frenzy is behind us, we will look back incredulously at the wreckage of failed ventures and wonder who funded those companies? What was going on in their minds? Was it just mania at work?” (41:38)

4. The Japanese Stock Market and Property Bubble (1980s)

[47:23–64:40]

Socioeconomic and Political Foundations

• Japan’s collectivist, government-supported corporate structure led to artificially low interest rates and encouraged speculation in stocks and property.
• “Japanese capitalism is in many respects the antithesis of the Western model... The hierarchy of the feudal system, it still remained in place.” (48:51)
• Land ownership was culturally revered and tightly held, fueling illiquid, speculative markets.

The Bubble’s Mechanics

• Deregulation, low interest rates, and financial engineering (“zytec”) enabled non-stop asset inflation.
• Feedback loop: rising prices boosted collateral values and enabled further easy lending, pushing prices even higher.

Excess and Mania

• Public IPO of NTT: 10 million applied for shares; stock traded at 200x earnings.
• Stock and property prices reached stratospheric levels:
  • “Tokyo property was valued more than the entire real estate value of California...” (58:24)
• Speculation reached even to golf club memberships, which became tradeable assets backed by margin loans.

Collapse and Legacy

• New central banker’s mission: “prick the bubble.” Six rate hikes deflated easy credit, popping both stock and property prices.
• Share and property prices fell by 60%; Japan entered decades of deflation and economic stagnation.
• “In 1989, the market peaked around 39,000 and it wouldn’t reach that level again until 2024. That’s 35 years later.” (62:03)

Key Lessons

• Belief in government or institutional guarantees leads to risk blindness.
• Speculative frenzies breed fraud, exposed only once collapse begins.
• “The bigger the bubble, the longer it can take for things to normalize.” (62:55)

Notable Quotes & Memorable Moments

• On the psychology of bubbles:
  • “When you study bubbles, you’re really studying how otherwise irrational people can trick themselves into becoming delusional.” (13:36)
• Sir Isaac Newton on the South Sea Bubble:
  • “I can calculate the motions of the heavenly bodies, but not the madness of the people.” (24:54)
• On risk and government’s role:
  • “Investors who purchase shares at such high levels are hoping for a greater fool to pay an even higher price… when the bubble pops, there’s rarely going to be ready buyers.” (28:03)
• On railways and tech manias:
  • “The railway mania is history’s first example of how a new technology does not necessarily bring good returns for the investor base at large.” (41:13)
• On Japan’s property and stock bubble:
  • “The grounds of the Imperial Palace in Tokyo was estimated to be worth more than the entire real estate value of California.” (58:24)
• On the aftermath:
  • “The final takeaway is that the bigger the bubble, the longer it can take for things to normalize.” (62:55)

Conclusion & Key Takeaways

• Each historical bubble shares common traits: rampant speculation, leverage, greed, institutional complicity, overconfidence, and the story that “this time is different.”
• Staying grounded in fundamentals and maintaining emotional discipline are the best defenses against falling into future bubbles.
• “Studying episodes like the South Sea Bubble, the Railway Mania, and Japan’s 1989 collapse helps us recognize when speculation crosses the line so we can protect our hard-earned capital by staying grounded in fundamentals and disciplined when enthusiasm is at its loudest.” (64:30)

Highly recommended for anyone looking to understand the recurring nature of financial manias, and to develop the intellectual tools necessary to avoid becoming their next victim.
