Donald Trump’s threat to impose 50% tariffs on Brazilian goods sent the country’s currency plunging as the US leader sharply escalated a dispute with Latin America’s largest nation and leftist leader Luiz Inacio Lula da Silva.

The U.S. will charge a 50% tariff on Brazilian goods starting on Aug. 1, President Trump announced in a letter to the Latin American country’s government on Wednesday, citing legal action against its former President Jair Bolsonaro and U.S. tech firms as justification for the levies.

President Trump vowed to impose 50% tariffs on imports from Brazil, citing a "witch hunt" of Brazil's former president.
