Financial Scandals
Every decade produces its share of financial scandals — from insider trading rings to multi-billion dollar frauds, from crypto collapses to banking failures that shook the global economy.
This is a curated guide to the most infamous cases in modern financial history. Some ended with prison sentences, others with suicides, and many with new laws designed to prevent the next one.
Classic Frauds

BCCI was a global bank secretly owned and controlled by a network of shady interests, used for money laundering, arms trafficking, and financing of terrorism. Its collapse revealed one of the largest banking frauds in history.

Ivan Boesky & Insider Trading (1986) Ivan Boesky (1986)

Enron (2001) Enron (2001)

Consequences: Enron filed for bankruptcy in December 2001, destroying $63.4 billion in market value. The scandal led directly to the Sarbanes-Oxley Act of 2002.

Banking Collapses & Systemic Fraud
