The Tale of Cantillon

The Man They Meant to Hang

On 9 April 1694, in Bloomsbury Square, a Scottish gambler named John Law killed Edward Wilson, a young dandy the town called Beau, with a single pass and thrust of his sword. The quarrel touched a lady, Elizabeth Villiers; the duel followed as a matter of course; and Law was condemned to death at the Old Bailey before Salathiel Lovell, a judge remembered chiefly for the relish with which he hanged people. The sentence dwindled to a fine on a finding of manslaughter, an appeal by Wilson’s brother returned him to a cell, and before the matter could be settled Law contrived an escape and got clean out of England, a fugitive not yet twenty-five, an Edinburgh goldsmith’s son with a gift for calculation that Europe’s gaming tables would spend twenty years subsidizing.

The exile made him, because he gambled through the capitals of the continent and studied their banks as he went, arriving at the conviction of his life: that the scarcity of money was a solvable defect, since whatever circulates will serve as money, and paper circulates far more obligingly than silver. Government after government declined the scheme, until September 1715, when Louis XIV died owing more money than his kingdom could count, and the Regent who governed for the five-year-old Louis XV, Philippe d’Orléans, proved to be a man of imagination, appetite, and empty vaults, the precise combination a monetary projector requires. In May 1716 Law opened the Banque Générale, a private bank of issue; at the close of 1718 it became the Banque Royale, its notes guaranteed by the King of France. In between came the Compagnie d’Occident, the Mississippi Company, holding the Louisiana trade monopoly, and through 1719 the Company swallowed its rivals until, restyled the Compagnie des Indes, it held the overseas commerce of France in one hand and reached for the mint and the tax farms with the other.

By design, the two halves of the System fed each other, for the bank printed the notes with which the public bought the Company’s shares, and the rise of the shares justified further notes, while the crown’s creditors, offered shares for their claims, were herded out of the state’s debts and into its equity. In January 1720 the fugitive of Bloomsbury Square was appointed Controller General of the Finances of France, twenty-six years after London measured him for a rope. Without quite intending it, he had also built the first full-scale laboratory for a monumental question: when somebody prints a country’s money, what happens inside that country, and who pays for what the printer buys?

Mushrooms of Fortune

The laboratory kept a street address, since from 1719 the rue Quincampoix, a narrow lane on the right bank of Paris, served as the open-air exchange for Mississippi shares, trading from first light until soldiers cleared it at nightfall. Charles Mackay, who warehoused the episode’s legends a century later, described the crowd: “Princes and priests, doctors of the Sorbonne, and shaven friars, mingled with money-shavers, shopkeepers, valets, and coachmen.” A cobbler with a stall in the lane, Mackay adds, made about two hundred livres a day letting it out to the brokers.

Even Mackay declines to vouch for the street’s most famous story, and I will extend it the same courtesy. “The story goes,” he writes, “that a hunchbacked man who stood in the street gained considerable sums by lending his hump as a writing-desk to the eager speculators!” No document supports the hunchback, but a city that believed in him instantly had already watched stranger things come true: Mackay also tells of a bedridden stockholder whose servant, sent to sell two hundred and fifty shares at eight thousand livres apiece, found the price at ten thousand, sold, handed his master the sum expected, and left the country that evening half a million livres the richer.

French found sudden work for a rare word. The earliest printed sightings of millionnaire cluster in exactly these months, and the Nouveau Mercure galant of October 1719 set the new species beside a second name, champignon de la fortune, the mushroom of fortune, the more honest of the two, a mushroom being a growth of a single night that feeds on whatever is decomposing underneath.

All the while the prices climbed: shares issued at five hundred livres, after a first year spent drifting below par, were driven above ten thousand by the turn of 1720, some twenty times their issue price, and the ascent survives day by feverish day in the price record assembled at Yale from the Dutch gazettes and the tables in Antoin Murphy’s Life of Law. Louisiana itself, mostly swamp and promise, could never have justified such a curve, and did not need to, because the justification issued nightly from the press, the Banque Royale’s notes in circulation multiplying more than sixtyfold between the spring of 1719 and the summer of 1720, by François Velde’s reconstruction for the Federal Reserve Bank of Chicago.

The Cold Eye in the Crowd

Somewhere in that crowd, unhurried and unenchanted, stood a banker from County Kerry named Richard Cantillon, and everything that follows in this essay descends from what he did in that street and wrote afterward. He had been born in the 1680s into a Hiberno-Norman family seated at Ballyheigue on the county’s Atlantic edge, a house that fought for James II and was stripped of its lands for the loyalty, and dispossession is a thorough school, whose graduates tend to hold theories of property considerably harder than other men’s. He came to Paris in the wake of an older kinsman who had followed the fallen king to France, commanded dragoons at the Boyne, and turned banker; by 1716 the younger Richard had a Paris bank of his own, in the remittance and exchange trade among Paris, London, and Amsterdam, which meant he was paid daily to know, sooner and more exactly than the next man, what one money was truly worth in another. A man with that training walked into the rue Quincampoix and saw no mystery there at all.

The System he judged unsound from the outset, and he traded it like a man trades what he does not believe in: he bought shares cheap and sold them into the rise, for a profit his own cashier put at two and a half millions, made in a few days. From the latecomers he reaped a colder harvest, lending at rates that reached fifty-five percent a year against their Mississippi and South Sea shares as security and then, on the reading of his modern biographer Antoin Murphy and of the borrowers who took him to law, selling the pledged shares near the top, so that when the paper collapsed the collateral had already been cashed at the height while the debts remained payable, principal and interest, in sound money, sterling above all. His clients, who had borrowed against a dream and woken owing him hard coin, hounded him to the end of his life and beyond it. Lady Mary Herbert and Joseph Gage, the speculating pair Alexander Pope called “congenial souls,” sued him for fraud and usury; twice he was briefly imprisoned; and his defense was as cold as the conduct, that shares are commodities, that a lender may deal in the security he holds, and that profit on a movement foreseen is trade and no crime. He moved the rest of the winnings out of the livre and into sterling and Dutch guilders, where the system could not follow; Henry Higgs, who edited the Essai two centuries later and pieced the life together, says simply that he “profited greatly by the fluctuations in the currency, which he foresaw.”

One scene from that period has outlived all account books, though it wears a label: it reaches us through Grimm’s literary newsletter of 1755, two decades after Cantillon’s death, and is therefore the story Paris chose to keep rather than a record of what was said. In it, Law summons the Irishman. “I can send you to the Bastille to-night,” he tells him, “if you don’t give me your word to quit the kingdom in four and twenty hours!” And Cantillon answers, “I shall not go away; but I will make your system succeed.” The threat wanted nothing in realism, because in Regency France a lettre de cachet, a sealed royal order, could imprison a man indefinitely without charge or trial, and the Bastille was furnished for such guests; a projector with the Regent’s ear had no need to win an argument he could end with a seal. What keeps the anecdote alive is the reply, for whether or not the words were ever spoken, the System did succeed, extravagantly, for the one man in the story who never believed in it.

The Course of New Money

The end, when it came, was administered by the crown, for on 21 May 1720 an arrêt reduced the face value of the Banque Royale’s notes and of the Company’s shares to roughly half. Meant as a controlled descent, it was read as an official confession that the state’s money was worth less than the state had sworn; the decree was withdrawn within a week, but a confession cannot be unsigned, and from that morning the only trade in Paris was paper for metal. By early June the Courrier politique et galant could jeer that the gentlemen millionaires should think themselves happy to lose no more than half. All summer, crowds stood from before dawn at the doors of the Banque Royale on the rue Vivienne to turn notes back into coin, until on 17 July 1720 the crush turned lethal. Mackay’s count agrees with the French record: “fifteen persons were squeezed to death at the doors of the bank,” and the crowd carried bodies to the Palais-Royal, the Regent’s own house, as if presenting a receipt. Law was stripped of his offices and out of France by December, his fortune and his System in ruins, and he died poor in Venice in 1729, having completed the arc the medieval chroniclers kept for princes, from the top of Fortune’s wheel to the mud beneath it. Cantillon had not stayed for the third act; he was gone with the winnings, and around 1730, in the shadow of the lawsuits those winnings had bought him, he set down what he had seen in one short book, the Essai sur la nature du commerce en général.

A confession as much as a treatise, the Essai was written by the man who had already worked the machine it describes, and its heart is the question Law had staged at the scale of a kingdom: when new money comes into a country, what happens, in what order, and to whom? His first move demolishes the comfortable arithmetic in which money is a neutral veil and prices merely scale with its quantity. “By doubling the quantity of money in a state,” he wrote, in Chantal Saucier’s translation for the Mises Institute, “the prices of products and merchandise are not always doubled. The river, which runs and winds about in its bed, will not flow with double the speed when the amount of water is doubled.”

New money, he saw, enters at a point, never everywhere at once, and from that point it moves through a country the way water moves down a canal, lock by lock, receiver by receiver. Whoever stands at the springhead (the crown and its Company then, the treasury and its dealers now) spends the new money while prices are still old, and that spread, new money against old prices, is the golden goose. At the second lock the banks and dealers receive it and lend it onward while the repricing has barely begun. At the third stand the owners of assets, whose houses and shares are the first prices the new spending finds and lifts; at the fourth, the merchants, who may at least raise their prices in reply. And on the floodplain at the bottom of the map waits the man paid a fixed wage, who owns nothing that reprices and sets no tariff of his own, and who therefore buys at the new prices for months or years before the new money condescends to reach his pay packet, because a wage is the last price in the kingdom to move. Cantillon called the roll of the sufferers without sentimentality, in Higgs’s older rendering, and the landlord locked into the term of his lease stands on it ahead of the workman: “Those then who will suffer from this dearness and increased consumption will be first of all the Landowners, during the term of their Leases, then their Domestic Servants and all the Workmen or fixed Wage-earners who support the families on their wages.”

The mechanism is cruel and indifferent, needing no wicked prince and no corrupted committee: the transfer from the last receivers to the first follows from the geometry alone, and those nearest the point where money is born would still, as the old advice runs, drink upstream of the herd under administrators of perfect virtue. The Austrians treated this as the foundation of monetary theory rather than a footnote to it. Mises rested his account of money on the recognition that a change in its quantity reaches prices, wages, and interest rates “neither at the same time nor to the same extent,” and Rothbard, constitutionally incapable of euphemism, added that “the government and its central bank act precisely as would a Grand Counterfeiter,” since both live on the spread between new money and old prices, and only one of them is ever prosecuted.

The Fire and the Manuscript

Cantillon removed to London, and about a year later, in the small hours of 14 May 1734, his house in Albemarle Street was found in flames. The body in the ruins was burned nearly past recognition, and the inquiry concluded that the man had been murdered before the fire was set. Suspicion settled on a cook dismissed some ten days earlier, who made away to Holland; a kinsman offered two hundred pounds for evidence; three of the household servants were tried at the Old Bailey and acquitted; and no one was ever convicted. A great part of his papers burned with the house.

So runs the documented account, and there the record closes. But Antoin Murphy, who spent a career reassembling Cantillon’s affairs, laid out in 1986 a stranger possibility, to be carried as exactly what it is, a conjecture built from circumstance. The corpse was said to lack its head, so the identification rested on assumption, and Cantillon had drawn a large sum from his bank that very day, while the servants’ testimony ran crosswise; then, half a year later, a traveler styling himself the Chevalier de Louvigny surfaced in the Dutch colony of Surinam, provisioned with gold and, more suggestively, with several of Cantillon’s personal documents, before slipping away from the authorities and out of the record. Murphy offers no verdict, and neither will I. But a man hunted through the courts for a dozen years by the people his loans had ruined had better reasons than most to die on paper, and if the father of the theory of vanishing purchasing power did vanish himself, gold in hand, then his life kept faith with his book to the last page.

The book’s own escape was narrow, for it survived in manuscript among the French economists, whose custody of it became a scandal: the Marquis de Mirabeau held a copy for nearly sixteen years and quarried his celebrated L’Ami des hommes out of it, a debt he confessed in a later letter to Rousseau. When the text finally reached print in 1755, twenty-one years after the fire, it wore a double disguise, claiming the imprint of Fletcher Gyles of London, a bookseller fourteen years dead, and announcing itself translated from the English, though no English original has ever been found, a costume cut to walk past the French censors. Then it fell out of sight for roughly a century, its arguments traveling much farther than its title page, until William Stanley Jevons, who owned a copy almost by accident, announced in the Contemporary Review in 1881 that “Cantillon’s essay is, more emphatically than any other single work, ‘the Cradle of Political Economy.’” Hayek, whose introduction to a German edition is collected in The Trend of Economic Thinking, marveled at a founding work that shaped a science and then vanished, “so that its purely accidental rediscovery was in the nature of a revelation.”

The Window and the Fan

It would be comforting to shelve all this among the antique follies, and the costume of the story, the sword fight, the hunchback, the livres, extends the invitation. The invitation however, is worth declining for a look at the machinery underneath: a sovereign in debt, a bank whose paper is the money of the land, an asset market levitated by that bank’s issue, and a public assured that the arrangement is science. The reader may decide which century he is standing in, for the inventory fits either without alteration.

After Law fell, the world’s paper experiments kept ending the same way, in a chastened return to metal, because so long as the holder of a note could demand coin, that humiliating possibility disciplined every issuer. When the state overreached, gold told them “no.” The problem is that Fiat never does. On the evening of Sunday, 15 August 1971, in an address televised to the nation, President Nixon closed the window at which foreign central banks could still exchange dollars for gold, the last hard tether in the system, and a suspension announced as temporary is now in its sixth decade. Every money on earth has been paper all the way down since, which means the springhead never runs dry.

What followed is easier to draw than to argue, and the drawing needs a single instruction: rebase the great American series to 100 at the summer of 1971 and let them run. By the spring of 2026 the NASDAQ stands at more than two hundred times its 1971 level, gold at more than one hundred, the broad money supply at roughly thirty, the median house at sixteen, while along the floor of the chart, nearly flat and nearly indistinguishable, crawl the consumer price index and the production worker’s hourly wage, each up some eight or ninefold across the half century. Not every fathom of that fan is the printer’s work, for earnings grew and technology compounded across the same decades, but every line on the chart is priced in the same shrinking unit, and the lines keep the order the man from Kerry set down, assets nearest the springhead riding highest, the wage below them all, the last price in the kingdom to move. Anyone who lays the Essai’s map over the government’s own series will find the canal drawn with a draughtsman’s precision.

When the banking system failed in 2008, the Federal Reserve met the crisis at the source, buying bonds with money that had not existed the day before, and its balance sheet, under a trillion dollars in 2007, stood near nine trillion at its 2022 peak, every dollar entering through the bond desks of the dealers nearest the spring, just where Cantillon’s map places them. Nor need you take an Austrian’s word for the intent. Ben Bernanke explained the second round of purchases in the Washington Post in November 2010 with a candor that deserves more fame than it has: “Higher stock prices will boost consumer wealth and help increase confidence, which can also spur spending.” There stands the whole of the Essai in one sentence of central-bank prose, and where France’s confession had to be extracted by a panicked decree and was withdrawn inside the week, this one was volunteered in the opinion pages and has never been retracted.

A policy of raising asset prices is a policy of enriching whoever already holds the assets, and by the Federal Reserve’s own distributional accounts the top one percent of American households now holds about a third of the nation’s net worth, while the bottom half holds a fortieth. Even the opposition conceded the mechanism long ago; it was, to the bane of my existence, John Maynard Keynes who wrote in 1919: “By a continuing process of inflation, governments can confiscate, secretly and unobserved, an important part of the wealth of their citizens.”

Seen whole, the arrangement is a toll on everyone who holds the money, since every act of issue transfers away a fraction of their purchasing power to whoever stands nearest the gate where the money is born. The toll appears in no budget, is voted by no parliament, and is collected from people who never see the gate, which is why it has outlasted every reform aimed at it. Cantillon’s private remedy was proximity, a seat beside the gate, available then as now to a very short list. The general remedy is a road with no toll booth on it, a money born nowhere in particular, with no first receiver: gold, whose supply answers to geology and toil and to no committee, and Bitcoin, whose issuance was written once, in code anyone may read, and answers to arithmetic.

The fever breaks the moment the age is measured in those monies. In January 1963 the median American house cost roughly five hundred ounces of gold; in the autumn of 2025 it cost a shade under one hundred, along a line that wanders with every panic and ends at a fifth of where it began. Priced in Bitcoin, across the decade for which a series exists, the same house has fallen from a little over eight hundred coins at the end of 2014 to between three and four by the same autumn. Nothing about the house explains this, because the median house sold today is, if anything, larger and better appointed than its 1963 counterpart, so the change must live in the yardstick, and a yardstick that shortens every year has had its name, in the King James rendering of the eleventh chapter of Proverbs, for well over two thousand years: “A false balance is abomination to the LORD: but a just weight is his delight.”

Richard Cantillon escaped the first paper flood with three advantages: a seat beside the springhead, the nerve to leave while the presses were still warm, and a money his adversary could not print. The first two belonged to one supremely placed banker, and they are no more on offer to the wage earner now than they were to Law’s coachman; nobody on the floodplain will be consulted about the next emergency, any more than Paris was consulted about the arrêt of 21 May. But the third has become common property within our own lifetime, because for the first time since the first mint opened, a person of ordinary means can keep the fruit of his hours in a money with no springhead at all, without a Paris bank or a barrel of gold in the hold of a ship bound for Surinam. The Essai waited twenty-one years for a printer and the better part of a century and a half for its due, while the machine it described has never once stood idle, not for the crash that discredited it nor for any reform since. A toll booth, whatever else may be said of it, can charge only the traffic that passes through it, and whether your hours keep passing through this one has become a choice.
