The Ibovespa jumped more than 1.5% to trade close to 188,000 on Tuesday following Monday’s holiday, posting broad-based gains. Petrobras rose more than 1.5% as oil prices surged following attacks on energy infrastructure in Saudi Arabia amid renewed hostilities in the Middle East. Vale gained about 2% as iron ore prices in China rose, driven by lower shipments and expectations of a seasonal recovery in Chinese demand. Meanwhile, a BTG/Nexus poll pointed to a technical tie between Flavio Bolsonaro and President Lula in a potential presidential runoff, although Flavio moved into a numerical lead of one percentage point. On Monday, a Quaest poll also showed the two tied at 41% in a second-round scenario. Flavio Bolsonaro is viewed by markets as more fiscally restrictive amid elevated yields and weak business activity. Major banks gained, with Itau up more than 2% and Bradesco adding more than 1.5%. Utilities rose as well, with Axia gaining nearly 2%. WEG and Rede D’Or both rose about 2%.
