by The First Global Financial Crashes and Lessons in Speculative Mania
This nomination for the orchestrators and victims of the interconnected Mississippi and South Sea Bubbles of 1720, the first worldwide financial crashes. The Mississippi Bubble, engineered by John Law in France, involved the reckless merger of a colonial trading company with the national bank and debt, fueled by printing paper money. The South Sea Bubble in England saw the South Sea Company’s shares soar on unrealistic promises to take over the national debt. Both were classic cases of speculative mania, where crowd psychology divorced prices from any underlying value. The collapses ruined thousands, discredited early financial systems, and led to prolonged economic stagnation. These bubbles proved that new financial instruments (joint-stock companies, paper money, debt-for-equity swaps) could be powerful tools for growth but also for catastrophic instability if divorced from reality and regulation. They established the enduring pattern of boom and bust inherent in modern capital markets.
