Bovespa closes 0.7 percent higher as CSN leads before vote

Bovespa closed on October 23, 2026 at 205,547 points, up 1,427 points or 0.7 percent from the previous session. The index gained after Brazil's October inflation preview came in below forecasts, while the presidential runoff kept political risk in focus, Estadao reported.

CSN led the session with a 7.6 percent gain. Ultrapar was the biggest reported decliner, down 2.2 percent, while Petrobras and Vale supported the benchmark, InfoMoney reported.

Why did Bovespa rise before Brazil's runoff?

The IPCA-15 rose 0.32 percent in October, below the 0.44 percent median forecast and the 0.70 percent increase in September. The result supported expectations for continued monetary easing, although 12-month inflation reached 4.62 percent, above the 4.50 percent tolerance ceiling, Reuters reported.

Election uncertainty limited the market's follow-through. Datafolha showed Flavio Bolsonaro and Luiz Inacio Lula da Silva tied at 50 percent of valid votes before Sunday's runoff. Brent crude traded at USD 116, helping Petrobras, while Vale recovered after earlier losses, Valor Economico reported.

Bovespa's leaders and laggard

CSN gained 7.6 percent, and Ultrapar lost 2.2 percent. The available closing coverage identified those two stocks as the session's leading mover and laggard. Bradesco also remained under pressure after its third-quarter results, despite profit in line with expectations, as asset-quality concerns weighed on the shares.
