"We want to put more money in consumers' pockets, and by eliminating credit card companies' anticompetitive rule, we will accomplish exactly that," Attorney General Eric Holder told an afternoon news conference. "The companies put merchants and their customers in a no-win situation" and "consumers are being held hostage."
MoneyWatch: What the Settlement Means to You
In papers filed in federal court in Brooklyn, the department and various state attorneys general sued all three companies, saying they were attempting to insulate themselves from competition.
At the same time, the Justice Department filed a proposed settlement with Visa and MasterCard.
Under the proposed settlement, Visa and MasterCard agree not to prohibit merchants from offering customers discounts or rebates for using a particular kind of card.
The lawsuit says the card companies are impeding merchants from promoting the use of competing credit or charge cards with lower acceptance fees.
Each time consumers use a credit card to make a purchase, the merchant must pay a fee. Such fees brought in $35 billion last year to the three credit card companies and their affiliated banks.
"We're partway there" with the proposed agreement with Visa and MasterCard, Assistant Attorney General Christine Varney, head of the department's antitrust division, told the news conference.
"We remain open" to seek a settlement with American Express," Varney added.
Shares of American Express are down more than 4 percent; Mastercard was down less than a percentage point, and Visa was up less than half a percentage point.
