U.S. Trade Representative Jamieson Greer announced the launch of an investigation into Brazil's digital trade policies, focusing on Pix, the central-bank-led instant payment system. The US accuses Brazil of excluding US companies with non-tariff barriers and preferential treatment, and of cracking down on US technology companies that refuse to cooperate with content censorship. Pix has become the heart of Brazil's digital economy thanks to its low cost and convenience.
