John Law tied a bank and a colonial dream into one bubble.

How John Law Made Paper Money Part of a Bigger Plan

In 1716, France was struggling with heavy debts left by the wars of Louis XIV. Scottish financier John Law proposed a way to get money moving without relying only on scarce coins: a bank could issue paper notes that people could use in everyday payments. His Banque Générale began as a private institution, though the government later took it over and renamed it the Banque Royale.

The notes were meant to be trusted as money, but Law’s plan did not stop at banking. He also gained control of companies granted trading rights in French territories overseas. These companies were eventually consolidated into the Company of the Indies, commonly called the Mississippi Company. Its shares offered investors a stake in anticipated trade and colonial development—not a guaranteed claim on profits already being earned.

Debt and Shares Became Entangled

Law’s most consequential move was linking the company to France’s public finances. Investors could exchange government debt for company shares, while the company gained a role in collecting taxes and managing trade. That arrangement promised to ease the state’s debt burden and gave the company a much larger business than overseas commerce alone.

The appeal fed on itself. Rising share prices made the scheme look successful, attracting more buyers; the bank’s paper notes also made it easier to pay for shares than if every purchase required metal coins. But the value of a share depended on expectations about future wealth, while confidence in the notes depended on faith in the bank and the crown. Those were related promises, not the same thing as money backed by a steady stream of company earnings.

When Confidence Reversed

As investors tried to turn paper claims into cash or coin, doubts about the system grew. Share prices fell, and the bank could not make every promise feel secure simply by issuing more notes. By 1720, the financial experiment had collapsed, damaging fortunes and public trust.

The episode showed the danger of making one institution’s money, a government’s debt, and a company’s speculative prospects depend on one another. When confidence cracked in the Mississippi Company, the shock spread beyond its shareholders—to the currency people used and the state finances Law had hoped to repair.
