Corruption is an international undertaking. A global cast of enablers, including oil-rich players from Abu Dhabi and Saudi Arabia, Caribbean letterbox companies, banks in Switzerland and Singapore, American real estate agents, and the giant investment bank Goldman Sachs, helped an ambitious young Malaysian businessman capture and spend over $4 billion in just a few years. Most oil boom corruption cases followed roughly the same playbook: spirit away illicit funds via offshore shell companies and bank accounts and then sink them into foreign property, businesses, luxury goods, and public relations campaigns. Through these channels, corrupt money and its destabilizing influence spread around the world.
