The leaked "Panama Papers" exposing holders of thousands of hidden bank accounts for possible violations of anti-bribery law could form the basis for a review by the U.S. Securities and Exchange Commission for possible signs of corruption, according to comments by the head of the agency's unit that fights foreign bribery.

Asked if the SEC was looking at the Panama Papers reports and to describe its investigative strategies in general, Kara Novaco Brockmeyer, chief of the SEC's Foreign Corrupt Practices Act (FCPA) said she could not comment specifically on the case, but noted that public-source information was one of several avenues for agency inquiries.

Asked whether this was an affirmative response to the initial question, she said, "It is a yes that we look at all public sources."

Brockmeyer spoke at a conference on Wednesday sponsored by the Securities Industry and Financial Markets Association. She did not elaborate. An SEC spokesman said later her comments were not meant to confirm formal action by the agency with regard to the leaked documents of Panamanian law firm Mossak Fonseca. The firm specializes in setting up offshore companies, often used to shelter the finances of politicians and public figures around the world.

Global scrutiny into offshore accounts detailed among the millions of leaked documents implicated scores of politicians and business figures internationally, though it has had limited fallout in the United States to date.

Hidden Money: Corruption Red Flag

Industry officials and regulators at the conference on anti-money laundering and financial crime said that laundered money is a red flag that points to a wide range of illegal practices, the most obvious being narcotics and terrorism network financing.

It also plays a lesser-known but critical role in many cases of bribery and corruption involving public officials and corporations subject to SEC oversight under the FCPA.

"There will be much for the SEC to review" in the massive leak of data on clients of the Panamanian law firm, said Ratan Narnolia, senior manager of Crowe Horwath's anti-money laundering compliance consulting practice.

Mossak Fonseca has said it was the victim of a computer hack, and that it has consistently acted appropriately.
