On Wednesday, the Ibovespa index declined by 0.7%, closing at 128,317 points as market sentiment was dampened by rising trade tensions and regulatory uncertainties. Concerns over disruptions in global supply chains have intensified following President Trump's new licensing requirements for Nvidia's advanced chips intended for China, alongside hints of possible fresh tariffs on semiconductors and pharmaceuticals. These policies are exerting pressure on technology and industrial companies that depend on the transnational flow of components while creating a ripple effect for commodity producers and financial institutions vulnerable to fluctuations in global demand. Although there was some support from China's strong Q1 growth, the broader market remains wary due to the potential for extended trade conflicts and mixed economic signals impacting Brazil's export-driven sectors. Notable companies including Petrobras, Vale, Eletrobras, and B3 were among the significant decliners, with losses ranging from 1.4% to 2.1%.
