Brazil Stocks Hit a Record as Real Gains | Brazil Market Report, Oct 9
Key Facts
- The Ibovespa, Brazil’s main stock index, rose 1.38% to a record close of 209,067 points on Friday 9 October, ending a week in which it gained more than 8%.
- The real strengthened to about 4.99 per US dollar, below the 5.00 level, as investors kept betting on a Flávio Bolsonaro win in the 25 October runoff.
- September inflation (IPCA) was 0.82% for the month and 4.58% over twelve months, above forecasts of 0.73% and 4.50% and above the 4.5% upper limit of the central bank’s target range.
- Oil eased after President Donald Trump said the United States would not attack Iran before the 3 November midterm elections: Brent fell about 1.3% to US$102.91 a barrel.
- Prediction markets: Polymarket gives Flávio Bolsonaro 89.0% and Lula 11.5% to win the presidency (US$179.6 million traded, as of 8:24 pm ET, 9 October). Bets, not polls.
Today’s Focus
Brazilian stocks closed at a record on Friday 9 October. The Ibovespa, the main gauge of the São Paulo exchange (B3), gained 1.38% to 209,067 points and is up about 11.7% since 1 October.
The rally is an election trade. Investors expect a Flávio Bolsonaro win in the 25 October runoff to bring a friendlier approach to spending and markets, and prediction markets now put his chances near 90%.
For a US investor, the real’s move matters as much as the index: the dollar now buys fewer than 5 reais, which lifts the dollar value of Brazilian shares and bonds.
What matters today. The election trade, not oil, is now the main force behind Brazilian assets. Inflation data did not change that view.
01 The session in one read
The Ibovespa closed at 209,066.90 points, up 1.38%. That is 2,847 points above Thursday’s close of 206,220 and a new record. The index touched an all-time high of 209,713 during the day and traded no lower than 206,238.
The real ended near 4.99 per US dollar. RT’s close was 4.9917, down 0.65%, and Brazilian press quoted 4.9851 for the commercial dollar, down 0.78%. The dollar has lost more than 4% against the real in five sessions.
In New York, the iShares MSCI Brazil ETF (EWZ), a fund that tracks Brazilian shares, rose 2.23% to US$43.54. The S&P 500 rose 0.59% to 7,811.54.
Three forces pointed the same way: the election trade, falling interest-rate futures and a stronger real. Lower oil took some support from Petrobras, but it did not stop the index.
A rally built on political expectations can reverse fast if the race tightens. One session cannot tell us how much of the 11.7% gain since 1 October is conviction and how much is positioning.

The IBGE statistics agency reported that the IPCA consumer price index rose 0.82% in September, against a market forecast of 0.73%, after a fall in prices in August. Twelve-month inflation was 4.58%, against a forecast of 4.50%. Electricity prices rose 7.98% as a billing credit ended. Some calendar feeds listed the September inflation rate as 0.70% and 4.47%, but those are the figures of the IPCA-15 preview, not of the full index.
Interest-rate futures, which show where investors expect Brazilian rates to go, fell on the day despite the inflation figure, Money Times reported. Rio Times · Live Market Intelligence

03 Why it moved: polls, rates and oil
The first driver was politics. Money Times called it the electoral trade: since the first round of voting on 4 October, investors have bought Brazilian assets on the expectation that Flávio Bolsonaro will beat President Luiz Inácio Lula da Silva in the runoff on 25 October. The Ibovespa has gained almost 9% in five sessions.
The second was the real. A stronger currency lowers import prices and the cost of dollar debt, which helps domestic companies such as banks and retailers.
Oil was a smaller factor. Crude fell after Trump said talks with Iran were productive and that the US would not strike before the midterm elections, according to La República of Colombia. Brent fell 1.3% and West Texas Intermediate (WTI), the US benchmark, fell 1.2% to US$90.40.

05 The regional scoreboard
| Index | Country | Change |
|---|---|---|
| Ibovespa | Brazil | +1.38% |
| IPC | Mexico | +1.63% |
| IPSA | Chile | +0.20% |
| Merval | Argentina | -0.16% |
| COLCAP | Colombia | +0.21% |
| S&P 500 | United States | +0.59% |
Four of the five Latin American indices rose on Friday. Brazil led again. Argentina’s Merval was the only one to slip, and Colombia’s COLCAP figure is a late-session reading.
06 The technical picture
The Ibovespa closed above its previous record close of 206,912 from Monday and printed a new intraday high of 209,713. Friday’s low of 206,238 stayed above Thursday’s close, so the index never gave back the previous day’s level.
For the real, 5.00 was the line traders watched. It now sits below it. A move back above 5.00 would be the first sign that the election trade is fading.
What Prediction Markets Say
On Polymarket, the Brazil Presidential Election market priced Flávio Bolsonaro at 89.0% and Lula at 11.5%, with US$179.6 million traded (read at 8:24 pm ET on 9 October). A day earlier, our reading was 85.7% and 13.5%.
A related Polymarket market on the runoff margin gave 49.5% to a Bolsonaro win by 4 to 8 points and 24.5% to a win by less than 4 points (US$0.4 million traded). Kalshi, a US exchange regulated by the CFTC (the US commodities regulator), also lists contracts on the vote. These prices are bets, not polls.
Why we show this: prediction markets turn real-money bets into a live probability that moves within minutes of the news, which is why investors, campaigns and newsrooms in the United States now follow them closely. We show them next to polls and official results, never instead of them.
07 What to watch
- Runoff polls: Each new poll before the 25 October second round, and each move in prediction markets, is likely to move the real and bank shares.
- The 5.00 line: Whether the real stays below 5.00 shows if foreign money is still arriving.
- Interest rates: With inflation at 4.58%, above the target ceiling, the debate over the Selic, Brazil’s policy rate, will shape bank and retail shares.
- Oil and Iran: Trump’s pledge covers only the period before the 3 November midterms; a new scare would lift crude and Petrobras.
