US Justice Department:- The U.S. Justice Department filed an antitrust lawsuit against Visa on Tuesday, alleging that the financial services behemoth uses its size and dominance to stifle competition in the debit card market, costing consumers and businesses billions of dollars.

The complaint says Visa penalizes merchants and banks who don't use Visa's own payment processing technology to process debit transactions, even though alternatives exist. Visa earns an incremental fee from every transaction processed on its network.

According to the DOJ's complaint, 60% of debit transactions in the United States run on Visa's debit network, allowing it to charge over $7 billion in fees each year for processing those transactions.

"We allege that Visa has unlawfully amassed the power to extract fees that far exceed what it could charge in a competitive market," said Attorney General Merrick Garland in a statement. "Merchants and banks pass along those costs to consumers, either by raising prices or reducing quality or service. As a result, Visa's unlawful conduct affects not just the price of one thing — but the price of nearly everything."

The Biden administration has aggressively gone after U.S. companies that it says act like middlemen, such as Ticketmaster parent Live Nation and the real estate software company RealPage, accusing them of burdening Americans with nonsensical fees and anticompetitive behavior. The administration has also brought charges of monopolistic behavior against technology giants such as Apple and Google.

According to the DOJ complaint, filed in the U.S. District Court for the Southern District of New York, Visa leverages the vast number of transactions on its network to impose volume commitments on merchants and their banks, as well as on financial institutions that issue debit cards. That makes it difficult for merchants to use alternatives, such as lower-cost or smaller payment processors, instead of Visa's payment processing technology, without incurring what DOJ described as "disloyalty penalties" from Visa.

The DOJ said Visa also stifled competition by paying to enter into partnership agreements with potential competitors.

In 2020, the DOJ sued to block the company's $5.3 billion purchase of financial technology startup Plaid, calling it a monopolistic takeover of a potential competitor to Visa's ubiquitous payments network. That acquisition was later called off.

Visa previously disclosed the Justice Department was investigating the company in 2021, saying in a regulatory filing it was cooperating with a DOJ investigation into its debit practices.

Since the pandemic, more consumers globally have been shopping online for goods and services, which has translated into more revenue for Visa in the form of fees. Even traditionally cash-heavy businesses such as bars, barbers and coffee shops have started accepting credit or debit cards as a form of payment, often via smartphones.

Visa processed $3.325 trillion in transactions on its network during the quarter ended June 30, up 7.4% from a year earlier. U.S. payments grew by 5.1%, which is faster than U.S. economic growth.
