São Paulo Stocks: Ibovespa, Petrobras and Vale — 2026-10-22
The Ibovespa has shown high volatility this week, swinging between record-adjacent highs and sharp corrections driven by tight polling data ahead of the Brazilian runoff election. While the index surged 1.57% on Tuesday, it pulled back on Wednesday as polls narrowed, with Petrobras and Vale experiencing divergent moves due to currency and commodity shifts. The Brazilian real remains stable near R$5.02 against the dollar, while the central bank maintains the Selic rate at 13.75% ahead of the November decision.

Top developments
Ibovespa swings on election polls
On Wednesday, October 21, the Ibovespa fell 0.86% to 206,495 points after a Quaest poll showed a narrowing one-point gap between candidates in the runoff. This followed a strong rally on Tuesday, October 20, when the index jumped 1.57% to 208,296 points, driven by bank stocks and optimism about the election outcome. The volatility reflects the market's sensitivity to polling data just days before the vote.
Petrobras and Vale diverge
Petrobras shares have faced pressure, falling 2.8% on October 19, while Vale has lost significant value, with investors reportedly rotating out of the miner. Local media notes that Vale has lost R$24 billion in market value as the dollar slippage and rising oil prices increase freight costs for exports, making Petrobras more attractive by comparison.
Real stabilizes near R$5.02
The Brazilian real has shown resilience, closing at R$5.02 against the dollar on October 21, holding steady despite the equity market's pullback. On October 20, the dollar fell 0.58% to R$5.02, marking its third straight drop, which helped support the broader market rally earlier in the week.
Local view
Local financial media, including Valor Investe and Forbes Brasil, are focusing heavily on the "technical tie" in polls between President Lula and Senator Flávio Bolsonaro. Valor Investe reported on October 16 that this uncertainty led to caution among investors, while Forbes noted on October 19 that the Ibovespa's discrete decline was largely due to adjustments in Petrobras shares as traders awaited clearer election signals.
