## Recent evidence

- [confirms] US revokes the visa of Brazil's ambassador as tariffs of up to 37.5% take effect (2026-08-05): The State Department revoked the visa of Brazil's ambassador as US tariffs of up to 37.5% took effect, framing it as reciprocity for Brazil's refusal of visas to two American diplomats and its delay in approving Trump's nominee in Brasilia. Trade penalties and diplomatic sanctions are being applied jointly over a bilateral protocol dispute, reinforcing for Brasilia the case for diversifying export destinations and settlement channels.
