Today’s Focus
Brazil’s main stock index, the Ibovespa, rose 0.54% to 205,430 points on Friday 16 October, ending a run of three straight losses. The commercial dollar fell 0.28% to R$5.073, so Brazil’s currency, the real, gained slightly.
Suno reported that oil-driven buying in Petrobras, up 4.04%, offset losses in the large banks. Brazil’s central bank activity index for August rose 0.3% as expected, which gave domestic stocks a small lift.
US investors mostly own Brazil through the EWZ fund and New York-listed shares. EWZ rose 0.60% to US$41.83, less than the local index, while the Nasdaq’s 2.14% drop kept global risk appetite low.
What matters today. Oil is now a Brazilian market driver as well as a global one, and the 25 October runoff keeps every rally exposed to the next poll.
01 The session in one read
The Ibovespa closed at 205,430.33, up 0.54% from Thursday’s 204,324.26. That ended three straight declines, although the index lost 1.74% over the week.
Petrobras, the state-controlled oil producer, rose 4.04% as international oil prices climbed on Middle East supply fears, according to Suno. The large banks lagged, with Bradesco down 1.78% and Banco do Brasil down 0.55%.
The commercial dollar fell 0.28% to R$5.073, according to Suno, after three consecutive gains. The index remains within 1.7% of its 9 October record.
Petrobras did most of the work, while the banks that weigh heavily on the index fell. A rally that depends on oil can fade quickly if crude reverses.
The exact weight of each stock in Friday’s gain is not confirmed. This reading is therefore approximate.
02 The day’s numbers
| Measure | Level | Change |
|---|---|---|
| Ibovespa (B3) | 205,430 | +0.54% |
| Commercial dollar (R$) | 5.073 | -0.28% |
| S&P 500 (US) | 7,659.44 | -1.09% |
| Nasdaq Composite (US) | 26,140.03 | -2.14% |
| EWZ fund (US$) | 41.83 | +0.60% |
The Dow Jones Industrial Average fell 0.34% to 52,002.41, so Brazil gained while Wall Street sold technology shares. The S&P 500 ended the week 1.9% lower and the Nasdaq about 4.5% lower, according to TheStreet.
EWZ, which holds Brazilian shares in US dollars, rose 0.60% to US$41.83 on the day. It gained less than the local index because the real strengthened only modestly.

03 Why it moved: oil and domestic data
Brent crude settled at US$109.86 a barrel and US crude (WTI) at US$101.41, according to Energy Now. Higher oil prices lift Petrobras directly, which is why the stock led the index.
Brazil’s central bank activity index, the IBC-Br, rose 0.3% in August against a forecast of 0.3%, after a 0.2% fall in July, according to the RT economic calendar. Domestic-focused stocks such as the retailers Assaí and Magazine Luiza gained.
The large banks fell on the day, which held back the index. Bradesco lost 1.78% and Banco do Brasil 0.55%.
04 The day’s movers
| Stock | Note | Change |
|---|---|---|
| Magazine Luiza | Retailer | +6.93% |
| Petrobras | State-controlled oil producer | +4.04% |
| Assaí | Food retailer | +4.22% |
| C&A | Clothing retailer | +3.46% |
| Banco do Brasil | State-controlled lender | -0.55% |
| Bradesco | Private bank | -1.78% |
| Petrobras ADR (US$26.00) | New York shares | +2.77% |
| Vale ADR (US$13.06) | Iron ore miner, New York shares | +0.31% |
| Itaú Unibanco ADR (US$9.44) | Largest private bank, New York shares | -0.63% |
Retailers led the gains because they are sensitive to interest rates and domestic demand. Petrobras gained 4.04% in São Paulo and 2.77% in New York, where the US-dollar move is smaller.
Banks held the index back. Itaú Unibanco’s New York shares fell 0.63% and Bradesco’s fell 1.74%.
05 The regional scoreboard
Mexico led Latin America on Friday while Brazil gained 0.54%. Mexico’s IPC rose 1.87%, Argentina’s Merval fell 0.35%, Chile’s IPSA was flat at −0.01%, and Colombia’s COLCAP fell 0.55%.
Oil explains part of the split, since Brazil and Mexico benefit from higher crude while Chile and Colombia trade on copper and domestic data. Chile ended the week 0.66% lower.
06 The outlook
Two things decide the next session: oil and the poll cycle. A reversal in crude would remove Friday’s main support, while a poll that shifts the race would move the real first.
The index is 1.7% below its record, so the longer trend is intact for now. A move back above R$5.10 per dollar would change that tone.
What Prediction Markets Say
Polymarket, a prediction market, priced Flávio Bolsonaro at 77.4% and Lula at 22.5% to win the presidency, with US$184.9 million traded (read at 8:22 pm ET on 16 October). The same platform priced a victory margin of under 4 points for Bolsonaro at 40.5% (US$1.9 million traded).
These prices are bets, not polls. They can move quickly on new surveys.

07 What to watch
- Polls: New runoff surveys before 25 October will show how the race develops.
- Oil: Brent above US$109 helps Petrobras, but a reversal would hit the stock first.
- The dollar: Watch whether the commercial dollar holds near R$5.07 or returns toward R$5.10.
- US data: US industrial production rose 0.7% in September against a 0.4% forecast, which keeps Fed rate bets in focus.
