The Ibovespa surged 1.7% on Thursday, closing at a record 171,497 points after U.S. President Donald Trump backed away from earlier threats of military strikes against Iran, easing geopolitical tensions. The reversal came just hours before the operation was reportedly set to begin, amid indications that negotiations with Tehran had progressed to the highest levels of the Iranian leadership and had gained support from a broad coalition of regional powers. Oil prices retreated on the news, alleviating inflation concerns and driving bond yields lower. Financial stocks led the advance, with Itaú up 2.9% and Bradesco gaining 2.4%. Vale rose 1.4% after inaugurating its first high-tech, AI-powered plant. Utilities also moved higher: Axia climbed 3.4% after completing the assignment of credits held against Amazonas Energia, while Engie jumped 3.9% following approval of a share offering tied to its planned acquisition of a stake in the Jirau hydroelectric plant. In the services sector, Rede D'Or advanced 4.7% after concluding its third share buyback program.
