2026-05-21 13:38 By Isabela Couto 1 min. read

The Ibovespa fell nearly 1% to trade below 176,500 on Thursday as investors assessed renewed tensions between the US and Iran.

Iranian leader Mojtaba Khamenei reportedly ordered that the country’s near weapons-grade uranium should not be shipped abroad, despite US President Donald Trump having assured Israeli allies that Iran’s enriched uranium stockpile would leave the country under any peace agreement.

Oil prices rebounded, reviving concerns that a war-driven energy shock could lift inflation and keep interest rates elevated for longer.

Banking shares traded lower, with Itaú down more than 1% and Bradesco losing nearly 1%.

Vale slipped close to 1% on weaker iron ore prices, while Petrobras gained over 1% alongside the oil rally.

Meanwhile, Itaú BBA downgraded Minerva (-5.6%) to “market perform” from “buy” and cut its target price, while Goldman Sachs upgraded Usiminas (+3%) to “buy,” naming it its top steel pick in Brazil.

Ibovespa Posts Biggest Daily Gain Since April
The Ibovespa jumped 1.8% to close at 177,356 on Wednesday, marking the benchmark’s biggest daily gain since early April, as easing oil prices and lower bond yields boosted risk appetite. Oil prices retreated after some ships managed to cross the Strait of Hormuz following 80 days of disruption, raising hopes that global supply conditions could gradually normalize. The pullback in crude prices helped ease inflation concerns and pushed bond yields lower, supporting financial stocks and the broader index. Itaú rose 2.3%, Bradesco gained 2.4%, and Itaúsa advanced 2.7%. Utilities also posted strong gains, with Auren Energia up 2.2%, Sabesp adding 2.1%, and Eneva climbing 4.1%. Other notable performers included Ambev (+2.6%) and Rede D'Or (+2.6%). In contrast, Petrobras fell 3.2% as oil prices declined.
