“Prices are rising, and consumers are paying more, while giant corporations are using inflation as a cover to expand their profits,” Warren said in a statement. “This bill would crack down on corporate price gouging by setting tougher rules of the road and enhancing enforcement, and I’m going to fight to get this done.”

The US consumer price index rose 8.3% on an annual basis last month, the government reported Wednesday.  The data indicated that the rising cost of shelter, food, airfare and new vehicles are among the biggest contributors to the elevated inflation, which may continue for months.

The legislation would give the FTC even broader powers than those in a plan Senate Majority Leader Chuck Schumer released last month to go after gasoline price manipulation. That bill also faces long odds in the Senate.

The bill would require public companies to disclose costs and pricing strategies. During periods of market shocks, companies would need to explain the changes to their costs of goods sold, margins and pricing strategies in quarterly regulatory filings. The legislation would also scrutinize companies that have told companies they are using inflation to hike prices and target companies that have outsized leverage to raise prices on consumers.

The bill would create exemptions for small businesses earning less than $100 million from some of the reporting requirements. The bill also provides $1 billion for the FTC to investigate price gouging.

The legislation is co-sponsored by seven other senators, including Democrats Bob Casey of Pennsylvania and Sheldon Whitehouse of Rhode Island, as well as independent Bernie Sanders of Vermont. Representatives Jan Schakowsky of Illinois, Jerrold Nadler of New York and David Cicilline of Rhode Island lead the House effort.
