U.S. Trade Representative Jamieson Greer named Pix, operated by Brazil's central bank, as one of the barriers to trade that ‌he cited to justify fresh 25% tariffs on imports from Brazil taking effect this week. "We're not asking Brazil to get rid of Pix," a senior Trump administration official said. Brazilian officials have long argued the criticism is aimed at protecting U.S. credit card companies. The tensions underline the growing threat of disruption posed by government-built payment infrastructure models such as Pix to credit card companies' decades-long dominance of global payments. The central bank launched Pix in 2020 and it quickly became the dominant payment method in Latin America's largest economy, overtaking card transactions by its third year of operation.
