Today’s Focus
Brazilian assets rose on Friday, 23 October, two days before the presidential runoff. The Ibovespa gained 0.47% to 205,083 points, though it still ended the week 0.17% lower.
The real gained 1.57% against the dollar and closed at 4.9654, below R$5 for the first time since 12 October. A slower monthly inflation reading helped the mood.
What matters today. Election positioning and softer inflation lifted Brazilian assets even as the S&P 500 fell 0.52%.
01 The session in one read
Brazil’s stock market closed higher on Friday, 23 October, as investors added risk ahead of Sunday’s second-round vote between President Luiz Inácio Lula da Silva and Senator Flávio Bolsonaro. The Ibovespa, the benchmark index of the biggest companies on the São Paulo exchange (B3), rose 0.47% to 205,083 points.
That left the index 1.9% below its 9 October close of 209,067, the highest this month. Brazilian business media such as InfoMoney described the session as one of late buying on election positioning, even though the index fell slightly over the week.
The real, Brazil’s currency, strengthened 1.57% to 4.9654 per dollar. For US investors, that also lifted the dollar value of Brazilian holdings by about the same margin, as seen in the EWZ fund, which rose 1.77% in New York.
The evidence points to investors adding exposure before the runoff rather than reacting to one piece of news. The real’s 1.57% jump and the slower IPCA-15 fit that pattern.
The move rests on a single event, though, and Sunday’s result can reverse it quickly in either direction. Watch whether the real holds below R$5 when trading reopens on Monday.
02 The day’s numbers
| Measure | Level | Change | Read |
|---|---|---|---|
| Ibovespa | 205,083 | +0.47% | Ended the week 0.17% lower |
| Close of 9 October | 209,067 | Highest close this month | |
| USD/BRL | 4.9654 | −1.57% | Real gains; first close below R$5 since 12 October |
| EWZ (Brazil fund, New York) | US$42.59 | +1.77% | Dollar-based view of Brazilian stocks |
The Ibovespa’s weekly change is measured against the 16 October close of 205,430. The real’s close below R$5 is the first since 12 October, when it ended at 4.9871.
The dollar index rose 0.14% on Friday, so the real’s gain came against a slightly firmer US dollar. Rio Times · Live Market Intelligence

03 Why it moved: runoff positioning and softer inflation
Two forces stand out. First, investors are positioning for the 25 October runoff, and Polymarket’s bettors price a win for Flávio Bolsonaro at about 77%.
Second, the IPCA-15, a mid-month gauge from the statistics agency IBGE, rose 0.32% in October, slower than the 0.70% of the previous reading. The 12-month rate was 4.62%, up from 4.47% in the previous reading.
Slower monthly inflation can ease pressure on the central bank, whose benchmark interest rate is called the Selic. The yearly rate rose, though, so hopes for rate cuts remain uncertain.
04 The day’s movers
| Driver | Level / Move | Change | Note |
|---|---|---|---|
| Vale (VALE, New York) | US$12.40 | +1.64% | Iron-ore miner rebounds |
| Petrobras (PBR, New York) | US$26.16 | +2.11% | Oil giant follows crude higher |
| Itaú Unibanco (ITUB, New York) | US$9.67 | +1.90% | Largest private bank in Brazil |
| Bradesco (BBD, New York) | US$4.07 | +3.04% | Major private lender |
We use the closes of New York-listed American depositary receipts, which are verified end-of-day prices, to show the single-stock picture. Brazil’s biggest lenders and its oil and mining champions all advanced.
Oil helped Petrobras: the Brent crude benchmark settled about 3.1% higher at US$116.72 a barrel on Friday.
05 The regional scoreboard
| Index | Country | Change |
|---|---|---|
| Ibovespa | Brazil | +0.47% |
| S&P/BMV IPC | Mexico | −0.30% |
| S&P IPSA | Chile | −0.31% |
| MSCI Merval | Argentina | +4.4% |
| COLCAP | Colombia | +0.44% |
Brazil, Argentina and Colombia rose on Friday, while Mexico and Chile slipped by about 0.3% each. Argentina’s jump of 4.4% in pesos was the standout.
The pattern reflects local stories, such as the runoff in Brazil and a rebound from a rise in country risk in Argentina, more than a regional wave.
06 The technical picture
The Ibovespa closed at 205,083, between its 20 October close of 208,296 and its 22 October close of 204,120. The 209,067 close of 9 October is the next level that traders will watch.
For the real, R$5 per dollar is the line that matters. A close back above it would suggest that investors are hedging the vote result; a move further below 4.99 would show growing comfort with the outcome.
07 What to watch
- Sunday’s runoff: The second round on 25 October decides who governs Brazil from January; the first moves in the real will show on Monday.
- Monday’s data: The central bank’s weekly Focus survey and the FGV consumer confidence index are due on 26 October.
- The real: A close above R$5 would undo Friday’s move.
- US stocks: The S&P 500 and Nasdaq both fell on Friday; a further drop would test Brazil’s risk appetite.
What Prediction Markets Say
