The lawsuit was first filed in 2012, with merchants alleging that Visa, Mastercard and a group of major issuing banks colluded to artificially inflate interchange fees, commonly known as swipe fees, which merchants pay every time a customer pays with a Visa or Mastercard credit or debit card. Prior to the settlement, these fees typically ranged from 1% to 3% of each transaction value, costing U.S. merchants an estimated $110 billion annually, with small businesses bearing a disproportionate share of the burden due to their lack of negotiating power with payment networks. Many small business owners have reported that swipe fees are their second-largest operating cost after payroll, forcing many to add credit card surcharges for customers or raise prices across the board to cover the expense. Under the terms of the approved settlement, two core provisions will take effect in the coming months. First, Visa and Mastercard will reduce interchange fees by a minimum of 0.1 percentage points for all eligible transactions for a period of 5 years, which is projected to deliver roughly $15 billion in total savings for merchants over that window. Second, a $23 billion cash compensation fund will be distributed to all U.S. merchants that accepted Visa or Mastercard payments between January 2012 and January 2024, with small businesses eligible for a higher proportional payout to offset their historical overpayments. The settlement also eliminates long-standing rules from Visa and Mastercard that barred merchants from offering discounts, cash back, or other incentives to customers who choose lower-cost payment methods such as cash, debit cards, or lower-fee credit cards, a change that is expected to drive more competition in the payments ecosystem. While the ruling has been praised by small business advocacy groups, some large retail associations have voiced criticism of the settlement, noting that the 0.1 percentage point fee cut is far smaller than the 0.5 percentage point reduction they had pushed for, and warning that the 5-year rate cap means fees could return to pre-settlement levels or even rise higher once the restriction expires. The settlement is subject to a 30-day appeal window, and several major retail chains have already signaled they may file a challenge to the terms. Consumer advocates note that if merchants pass even a portion of their fee savings on to customers, the settlement could lead to lower average prices for everyday goods and services across the U.S. economy.
