Brazil stocks dip 0.45% as oil prices fall on U.S.-Iran deal hopes

Brazil's B3 stock exchange in São Paulo experienced a downturn, with the Ibovespa index closing down 0.45% on Tuesday. The decline was primarily driven by a significant drop in the international price of crude oil, which negatively impacted the state-owned oil giant Petrobras.

The market reacted to news of a potential agreement between the United States and Iran concerning the Strait of Hormuz, a critical chokepoint for global oil and gas transport. U.S. President Donald Trump stated that the strait would be "fully open" to navigation, signaling a potential easing of tensions and increased supply. This development led to a fall in crude prices, affecting Petrobras's stock.

Petrobras's preferred shares, among the most traded on the exchange, fell by 1.3%, adding to a previous 5.1% loss from the prior day. Other major companies also suffered losses, with petrochemical firm Braskem dropping 9.2% and steelmaker Usiminas down 6.2%. Conversely, supermarket chain Pão de Açúcar saw its shares rise 9.6%, and ethanol producer Raizen gained 2.3%.
