The U.S. Department of Justice's Antitrust Division and the Federal Trade Commission announced they are closely monitoring petroleum markets and gasoline prices and are prepared to take enforcement action against companies that engage in illegal conduct that artificially drives fuel prices higher.

The agencies also sent a letter to state attorneys general encouraging them to investigate potential violations of state antitrust and consumer protection laws. Federal officials urged states to pursue enforcement actions against companies suspected of manipulating retail fuel prices, colluding with competitors, or engaging in other unlawful conduct within petroleum markets.

According to the agencies, state participation will play an important role in identifying and stopping potential price gouging and other anticompetitive behavior that contributes to higher gasoline prices for American consumers.

"Affordable energy is essential to a thriving American economy. The Antitrust Division is committed to working alongside state law enforcement partners to protect consumers from anticompetitive conduct that increases the price of gasoline. We will use all available tools to hold companies accountable for unlawfully manipulating the market."

— Associate Attorney General Stanley Woodward

The Department of Justice is encouraging members of the public to report suspected antitrust violations through its Citizen Complaint Center. Officials also noted that individuals who provide information leading to successful enforcement actions may qualify for significant financial rewards through the department's whistleblower program.

Consumers who believe they have witnessed price manipulation, collusion, or other deceptive business practices may also submit complaints directly to the Federal Trade Commission.
