In the late 1990s, America experienced a dot-com mania. In the 2000s, the housing market went wild.
Today, there are manias in everything from bitcoin and nonfungible tokens to SPACs and meme stocks – obscure corners of the market that are getting increased attention. Whether these are the next bubbles to burst remains to be seen.
The sudden rise of all these relatively new asset classes – or the astronomical heights they’ve reached – may seem irrational or even enchanted. Describing them as speculative manias implies that individuals are lost in forces beyond their control and needn’t take responsibility for the actions of the crowd.
Adam Smith and the rise of financial speculation
From ancient times until the late 1700s, the term “speculation” was used mainly by philosophers, scientists and authors to describe conjectures about the future. When speaking of traders who manipulated the prices of an asset to make an outsize profit, financial writers instead used terms like “engrossing” or “cornering” the market.
After a series of international credit scandals in the 1770s, though, “speculation” became the favored descriptor for high-risk financial gambling. Political economist Adam Smith used the term extensively in “Wealth of Nations,” published in 1776, after seeing it used to describe lotteries and smuggling. He saw in it a perfect term for how traders were trying to capitalize exponentially on the inherent risks and unknowns of the future.
George Washington even warned in 1779 that speculators “are putting the rights & liberties of this Country into the most eminent danger.”
Yet Smith, Washington and others still saw speculators of all types as individuals making calculated decisions, not as part of some maniacal collective or epidemic contagion.
Alexander Hamilton’s ‘scripomania’ takes hold
That began to change thanks largely to the early American physician and thinker Benjamin Rush.
As surgeon general of the Continental Army and a prolific publisher of studies of mental illness, Rush penned a widely circulated article in 1787, “On the Different Species of Mania.” In it, he characterized speculative gambling alongside 25 other types of “manias” that he wrote had become pronounced in American life, including “land mania,” “horse mania,” “machine mania” and “monarchical mania.”
For Rush, speculation was a disease of the mind that spread from one to many and threatened the health of a young democracy that relied on rational decision-making by voters and politicians. The “spirit of speculation,” he foresaw, was not a good-hearted “spirit” of nation building, but rather could “destroy patriotism and friendship in many people.”
Rush’s terminology and his way of thinking caught on quickly. In the summer of 1791, “Scripomania” took hold as Alexander Hamilton sold the rights to buy shares – known as scrips for “subscriptions” – in the newfound Bank of the United States to shore up the nation’s finances following the Revolutionary War. Demand for the scrips soared; the Philadelphia General Advertiser declared that “an inveterate madness for speculation seems to possess this country!”
Calculated risk – minus the calculation
After that, the tie between “speculation” and “mania” spread and became inextricable – and it hasn’t been severed since. The Scottish journalist Charles Mackay sealed this connection in 1841 with his influential “Extraordinary Popular Delusions and the Madness of Crowds.” Since then, virtually every bubble, every rush in commodities and every market panic that has ensued has been called a “mania.”
The term has even been used retrospectively to refer to the behaviors that led to speculative bubbles in the distant past. The famous Dutch tulip bubble of 1637, for instance, was seen in its day as foolish and dangerous, but only after Mackay’s book was it labeled a “mania.”
The trouble with talking about wild financial events in this way is that society begins to confuse and distort the responsibility and nature of bubbles that inevitably crash, leaving ruin in their wake.
To speculate, at its core, is to make a bet about the future based on individual calculations of the risks of tomorrow. There’s nothing inherently contagious or mad about it. In fact, computers are often speculating now in place of human minds.
What we call a “mania” is just shorthand for saying that a lot of people – and machines – made the same bet, as happened in January when day traders – many of them inexperienced – drove up the price of GameStop. Maybe they were all acting rationally and in concert. Maybe they were duped by insiders or weren’t fully calculating those risks.
Whatever the explanation, using the term “mania” tells us only a small and potentially misleading part of the story.
