In short: A massive leak from a single law firm revealed how some of the world's most powerful individuals hide their riches. By sifting through millions of confidential documents, an international network of journalists turned a private secret into a public reckoning on global finance.

The International Consortium of Investigative Journalists (ICIJ) is a U.S.-based global network designed to expose international crime and corruption. Charles Lewis established this Center for Public Integrity project in 1997, which expanded to include 39 nations and 75 reporters by 2000. In 2017, it achieved full independence as a nonprofit organization governed by three distinct committees: a board of directors, an Advisory Committee, and a Network Committee. The organization currently maintains a presence in countries like Australia, France, and Serbia. It operates as an independent network of over 280 journalists today.

The ICIJ gained global prominence through its collaboration on the Panama Papers in 2016. Journalists examined 11.5 million leaked files from Mossack Fonseca, a Panama law firm, over one year alongside 100+ media outlets like The Guardian and Le Monde. These documents revealed how entities used offshore accounts to conceal wealth, avoid taxes, and launder money. The leak exposed more than 214,000 offshore entities and provided details on over 14,000 clients, including heads of state and government officials from more than 40 countries. The data first reached the German newspaper Süddeutsche Zeitung from an anonymous source in 2015. These files also showed how firms helped people dealing with sanctioned leaders like Bashar al-Assad.

The impact of these investigations has been tangible. For instance, the Panama Papers alone helped governments recover more than US$1.36 billion in taxes. Other projects, like the Swiss Leaks in February 2015, exposed accounts for 100,000 clients at HSBC. Furthermore, ICIJ's work on the Pandora Papers led to the proposal of the Enablers Act in the U.S., while their investigations have contributed to legislative shifts like the Corporate Transparency Act. In early November 2014, their Luxembourg Leaks investigation highlighted a major European hub for corporate tax avoidance. The ICIJ shared the Panama Papers material with 107 different media organizations across 80 countries.
