The year nobody talked: how the biggest leak in journalism stayed secret

The message arrived in 2015 at a newsroom in Munich: “Hello. This is John Doe. Interested in data?” icij.org The reporter who received it, Bastian Obermayer of Süddeutsche Zeitung, was interested. The source insisted on encrypted channels, refused to meet in person, and warned that being identified would endanger his life. icij.org

What John Doe delivered became the largest leak journalism had ever received: 11.5 million confidential documents from a Panamanian law firm called Mossack Fonseca—2.6 terabytes covering nearly forty years of emails, financial spreadsheets, passports and corporate records, from one of the world’s most prolific creators of shell companies, a firm with offices in more than 35 locations around the globe. icij.org

Then Süddeutsche Zeitung did the thing this story is actually about. It gave the scoop away.

Obermayer and his colleague Frederik Obermaier had worked on ICIJ collaborations before, and they judged the material too large for any single newsroom—this was cross-border reporting at a scale no one paper could pull off. Their editor, Wolfgang Krach, approved handing the project to the International Consortium of Investigative Journalists to share worldwide. icij.org A newspaper holding the exclusive of the decade chose, on purpose, to multiply its competitors.

What followed was a year of silence held by the least silent profession there is. More than 100 news organisations worked the same archive in 25 languages across nearly 80 countries, and ICIJ’s own tally of the project ran past 400 people once the editors, programmers and fact-checkers behind the bylines are counted. icij.org icij.org ICIJ’s Marina Walker Guevara set the rule plainly: “You have no business talking about this work with your spouses, with your friends, with your parents.” icij.org Rival newsrooms—competitors on every other story they touched—held one embargo together, and it held. On 3 April 2016, everyone published at once.

The reporting mapped more than 214,000 offshore companies connected to people in more than 200 countries and territories. icij.org The fastest political consequence landed in Iceland, where the prime minister resigned within forty-eight hours—a case this desk has followed in full. icij.org Mossack Fonseca itself shuttered within months. icij.org Over the decade since, governments have recovered approximately $2 billion in taxes, penalties and levies traced to the files. aljazeera.com

In 2017 the Pulitzer board handed its Explanatory Reporting prize to ICIJ, McClatchy and the Miami Herald, crediting “a collaboration of more than 300 reporters on six continents to expose the hidden infrastructure and global scale of offshore tax havens.” icij.org

The scoop of the century turned out to be worth most to the paper that refused to keep it.

Comment

The Questions It Leaves

The collaboration was not a nicety on top of the journalism. It was the journalism. A single newsroom reading 11.5 million documents alone misses what a Maltese reporter recognises instantly in a Maltese name, and a reporter who publishes alone in a country where naming the powerful is dangerous stands alone when the powerful respond. Publishing simultaneously, everywhere, spread the risk across eighty countries in one morning. The method was the protection.

Which leaves two questions this desk keeps asking. If sharing the scoop is what beat offshore secrecy—and the prize board’s own citation says it was the collaboration that did it—why is hoarding still the industry’s default? And who pays for the next one? The model that produced the Panama Papers runs on grants and reader donations, not on subscriptions or exclusives. The next John Doe will message somebody. Whether a hundred newsrooms answer together depends on money nobody has promised yet.

What You Can Do

Read the reporting itself—ICIJ’s ten-year retrospective is the fullest account of how the collaboration worked. icij.org

If this account proved useful, the credit belongs to the reporters who kept a secret for a year so they could tell it properly. We follow their reporting to keep it from disappearing. The ICIJ operates through reader support. icij.org
