Securities and Commodities Fraud

The MIMF Unit specializes in the investigation and prosecution of cases involving publicly traded securities. These cases include accounting fraud at publicly traded companies, insider trading, false statements, market manipulation, and other schemes. The Unit also has devoted particular attention to cases involving officers of publicly traded companies who deceived investors in connection with the COVID-19 crisis. For example, prosecutors in the Unit secured the conviction of the president of a Silicon Valley-based medical technology company for participating in a scheme to mislead investors, commit health care fraud, and pay illegal kickbacks in connection with the submission of over $77 million in fraudulent claims for COVID-19 and allergy testing.

The Unit also is the national leader in prosecuting fraud and manipulation in the U.S. commodities markets, including spoofing, insider trading, and benchmark price manipulation.

Prosecutors in the Unit use data analysis and traditional law enforcement techniques to identify and prosecute complex fraud, manipulation, spoofing, and insider trading cases involving commodities and securities markets. Prosecutors have developed unique algorithms to comb market-wide trade data for patterns indicative of manipulative trading practices, and frequently work in parallel with the U.S. Securities and Exchange Commission and U.S. Commodity Futures Trading Commission.

In connection with an ongoing market manipulation probe, the Fraud Section has convicted 12 commodities and securities traders at global financial institutions, including a Managing Director and six Executive Directors who were convicted after jury trials. Since 2019, as part of the same probe, the Fraud Section entered into landmark corporate resolutions relating to violations of the commodities and securities laws—including with JPMorgan Chase, The Bank of Nova Scotia, Merrill Lynch Commodities, Deutsche Bank AG, Tower Research Capital, Propex Derivatives, and NatWest Markets—with a combined total monetary amount of over $1.1 billion.

Separately, the Unit convicted a former oil trader in connection with a scheme to manipulate fuel oil prices in the Port of Los Angeles, one of the nation’s busiest commercial ports. In a related case, the trader’s employer, Glencore Ltd.—one of the world’s largest commodities mining and trading companies—pleaded guilty to a conspiracy to manipulate benchmark prices and agreed to pay $485 million in criminal fines and forfeiture.
