When Louis XIV died in 1715, France faced severe debt and strained tax revenues. The regency government under Philippe d’Orléans looked for new ways to stabilize state finance and restore confidence. This crisis set the stage for John Law’s banking and company experiment.
In May 1716, John Law received a charter to create the Banque Générale, a private joint-stock bank. The bank issued paper notes intended to be more convenient and stable than often-debased coin. This was an early French attempt at what would now be called central-bank functions: issuing widely used money and supporting state finance.
In 1717, Law launched the Company of the West (Compagnie d’Occident), often associated with the later “Mississippi Company” name. Shares were marketed as a way to profit from colonial trade and development, and could be paid for with government paper, linking the company directly to France’s debt problem. This connected speculation in company stock to state finance and the money supply.
Soon after gaining its charter, the Company of the West directed colonial officials to create a new settlement upriver for better access and defense. This plan became the basis for New Orleans, intended as a strategic and commercial hub in French Louisiana. Promises about colonial wealth would later help fuel investor excitement in Paris.
In 1718, Bienville began developing the settlement that became New Orleans, named to honor the Regent. The colony’s real conditions were far harsher than promotional claims, which mattered because the bubble relied on optimistic expectations. The growing gap between marketing and reality became a hidden weakness in the scheme.
In late 1718, the state took over Law’s bank, and it soon operated as the Banque Royale with royal backing for its note issue. This shift increased public confidence at first, because banknotes now appeared tied to the crown. It also increased the state’s direct role in money creation, raising the risks if confidence later turned.
In 1719, Law’s Company absorbed other French trading companies and took the name Compagnie des Indes. The mergers enlarged the story investors were buying: a single powerful company controlling major overseas commerce. This expansion helped drive demand for shares and pulled more of the French economy into Law’s system.
By late 1719, trading in company shares became frantic, supported by large issues of banknotes that made it easier to buy stock. The boom fed on itself: rising prices attracted more buyers, and more credit helped push prices higher. This created classic bubble conditions where asset prices grew faster than real economic output.
On 5 January 1720, the Regent appointed John Law as Controller-General of Finances, giving him sweeping authority over state finance. At roughly the same time, share prices reached extreme highs, reflecting confidence that the government would support the system. This concentration of power tied the fate of the state even more tightly to the bank and the company.
In February 1720, the Company absorbed the Banque Royale, tightening the link between share prices, state debt conversion, and the note supply. With the bank and company effectively acting together, a fall in confidence could now hit both at once. The structure made the financial system more unified, but also more fragile.
On 21 May 1720, Law attempted a controlled cooling-off by ordering a planned reduction in the value of banknotes and company shares. Instead of calming markets, the measure alarmed holders of notes and stock by signaling that official values could be cut by decree. Confidence fell sharply, and the policy was soon reversed, but the damage to trust remained.
As people rushed to turn paper claims into safer forms of value, crowds gathered in Paris to sell shares or redeem notes. On 17 July 1720, panic contributed to a deadly crush during the turmoil around the Mississippi scheme. The episode showed that the bubble was no longer just a market story—it had become a public order and social crisis.
By late 1720, confidence in banknotes had deteriorated and the state moved to end the experiment. The Banque Royale officially closed on 27 November 1720, marking a clear institutional end to Law’s central-banking project. The collapse left deep distrust of paper money and financial innovation in France for decades.
After losing power and protection, John Law left France in December 1720. The government continued unwinding the monetary and corporate structure he built, separating overseas trade from domestic money and tax administration. His departure symbolized the political and financial closing of the Mississippi Bubble era.
