Bursting Bubbles and Broken Brains: The Madness of the South Sea Scheme
by Timothy J. Videnka, CFA, CFP®
“Bubbles, bright as ever Hope
Drew from fancy – or from soap;
Bright as e’er the South Sea sent
From its frothy element!See!—But hark my time is out —
Now, like some great water-spout,
Scaterr’d by the cannon’s thunder,
Burst, ye bubbles, burst asunder!”– From the poem “An Incantation” by Thomas Moore
Regular readers of our newsletter know that we like to profile historical episodes of financial manias and the ensuing panic. From Tulips to tech stocks, these episodes have a habit of repeating themselves with some regularity. An event that we had yet to feature – until now – took place in the early 1700s and ensnarled one of science’s greatest minds.
The South Sea Bubble wasn’t just a financial disaster – it was the 18th century’s version of a get-rich-quick scheme gone wildly, hilariously, and tragically wrong. It’s been called the first major financial crash, the first Ponzi scheme, and a prime example of what happens when people collectively lose their minds chasing easy money. Even Sir Isaac Newton, one of the greatest brains in history, got swept up in the madness. He reportedly lost the equivalent of £40 million in today’s pounds ($50 million USD equivalent), later quipping, “I can calculate the motion of heavenly bodies, but not the madness of people.” If only he’d kept his money where he kept his apples. See the chart below illustrating Newton’s South Sea experience:
The chaos started in 1711, when the South Sea Company was founded with the lofty goals of reducing Britain’s national debt and boosting trade in the Americas. It sounded like a win-win. Investors were dazzled by promises of untold riches from the slave trade. Everyone imagined a treasure trove of gold and sugar pouring in. But when the War of the Spanish Succession ended in 1713, Spain pulled a fast one, limiting trade to one ship a year and skimming profits. In other words, the company was trying to turn a profit with all the trading potential of a lemonade stand.
Then came the genius marketing. King George hopped on board as governor in 1718 and investors thought, “If it’s good enough for the King, it’s good enough for me!” The stock skyrocketed. The company was offering 100% returns, which should have been a red flag but, apparently, greed blocks basic math and reasoning skills. The company wasn’t making money from trade – it was just selling its own stock in a financial version of hot potato. Naturally, the King didn’t mind – he was too busy collecting his dividends.
Things took a truly bonkers turn in 1720 when Parliament let the South Sea Company take over the national debt. The company paid £7.5 million for £32 million worth of IOUs. How would they cover it? By selling more stock, of course! It was a self-perpetuating cycle: more stock sales led to higher prices, which led to even more investors scrambling to get in on the action. By August, shares hit an absurd £1,000 each, roughly the cost of an actual ship back then.
Then the bubble burst. By December 1720, shares had plummeted to £124. Fortunes evaporated overnight, investors were left clutching worthless paper, and London became a city of very awkward dinner parties. Suicides increased, mobs took to the streets demanding answers, and Sir Isaac Newton presumably sat in a corner muttering about gravity and regret.
Parliament launched an investigation and found corruption everywhere. Bribes had been flying around like pigeons in Trafalgar Square. One man who wasn’t fooled by the hype was Archibald Hutcheson, a pamphleteer who kept shouting that the stock wasn’t worth more than £200. Nobody listened but he got the ultimate “I told you so!” moment once the dust settled.
Enter Robert Walpole, the political Mr. Fix-It. He became Chancellor of the Exchequer (equivalent to U.S. Treasury Secretary) and managed to stabilize the situation, earning himself the title of Britain’s first Prime Minister. To prevent future disasters, Parliament passed the Bubble Act, requiring royal charters for joint-stock companies. Essentially, no more “fly-by-night” corporations promising to turn hay into gold.
Amazingly, the South Sea Company limped on until 1853, most likely to serve as a cautionary exhibit. Meanwhile, some of the “bubble companies” spawned during the mania, like the Royal Exchange and London Assurance, are still around today, proving that not all schemes were total disasters.
The South Sea Bubble remains a timeless cautionary tale of groupthink and too-good-to-be-true promises. It’s proof that even the smartest people (and monarchs) can make fools of themselves chasing easy money. It is a further reminder that returns – and the often-forgotten risk – both need to be monitored and cannot be separated.
