The Ibovespa rose about 1% to hover around the 178,000 mark on Monday following the release of new presidential election polls.
The BTG/Nexus poll showed President Lula with 46% of voting intentions in a potential runoff versus 45% for Flávio Bolsonaro, viewed by markets as more fiscally restrictive amid elevated domestic yields and weak business activity, a technical tie.
The AtlasIntel/Bloomberg poll showed Lula with 47.1% and Flávio Bolsonaro with 42.6% in a potential runoff, with Lula’s lead narrowing to 4.5 percentage points from 6.3 points in the previous poll released in July.
Gains were broad-based, with Petrobras (+3%) outperforming as oil prices rebounded amid escalating Middle East tensions, with the US and Iran exchanging strikes for the first time in roughly a month.
Major banks rose by up to more than 2%.
Utilities also advanced, with Axia up over 1%.
Vale gained about 1% as iron ore prices increased.
