According to Golden Finance, US Trade Representative Jamieson Greer announced the launch of an investigation into Brazil's digital trade policies, with a focus on the central bank led instant payment system Pix. The US accuses Brazil of using non-tariff barriers and preferential treatment to exclude American companies, and suppressing American technology companies that refuse to cooperate with content censorship. Pix has rapidly become the core of Brazil's digital economy due to its low cost and convenience.
