Petrobras is trading 4.27% up at $20.98 after crude prices climbed toward $97 on September 8, 2026.
- Brent gained as escalating US-Iran attacks raised concerns about disruptions through the Strait of Hormuz, a major global oil route.
- The move appears primarily sector-driven, with no major Petrobras announcement identified. Broader equities were weaker, making the oil rally the clearest supportive catalyst.
