The Ibovespa reversed early gains to close 0.55% lower on Friday, at 195,734 points, slipping back to levels last seen on April 9. Initial optimism following the reopening of the Strait of Hormuz faded as a sharp 9.86% drop in oil prices, to $85.35 per barrel, put significant pressure on the index.
Petrobras was the main drag, tumbling 5.05% and surrendering the advance triggered by news of its acquisition of a stake in offshore block 3 in São Tomé and Príncipe. In contrast, Vale climbed 1.51% after reporting resilient first-quarter production figures.
The banking sector largely underpinned the broader market amid falling bond yields. Banco do Brasil (+0.78%), Santander Brasil (+0.70%), and Bradesco (+0.77%) all advanced, while Itaúsa slipped 0.27%.
Among other notable movers, Rede D'Or gained 1.53% and WEG added 0.54%, whereas Eletrobras dropped 2.81% and Ambev declined 0.78%.
