Today’s Focus
Brazil’s main stock index closed down 0.26% at 182,991 points on Monday. It was the fourth loss in a row. Global risk aversion, higher US Treasury yields and weak bank shares outweighed gains in oil producers.
The real lost ground. The dollar rose 0.86% to 5.2255 per US dollar. The dollar gained 1.74% against the Mexican peso and 0.71% against the Chilean peso.
Election polls added caution a week before the 4 October first round. A BTG Pactual/Nexus survey showed President Lula ahead of Senator Flávio Bolsonaro in the first round, with the runoff still close.
What matters today. A dense domestic data day and fresh election polls, with oil and US yields setting the global backdrop.
01 The session in one read
The Ibovespa—Brazil’s main stock index—closed down 0.26% at 182,991 points on Monday. It traded between 181,931 and 184,095 and ended below 183,000. The index has now lost about 2.4% since 22 September.
The real, Brazil’s currency, weakened to 5.2255 per US dollar, a 0.86% rise for the dollar. The Mexican and Chilean pesos also lost ground.
The split inside the index was clear. Banks, retailers and other domestic names fell. Oil producers rose with crude prices, which climbed as US–Iran negotiations stalled.
Polls kept investors cautious. A BTG Pactual/Nexus survey put Lula at 42% and Flávio Bolsonaro at 37% in the first round, and 46% to 44% in a runoff—a statistical tie.
The evidence points to a global risk-off day with a local election overlay. Higher oil prices and rising US yields hit rate-sensitive banks and domestic stocks, while oil producers gained. The real’s slide matched weakness in the Mexican and Chilean pesos, so global forces mattered at least as much as local politics. With the first round on 4 October, polls will keep positioning cautious. The next Copom meeting is on 3–4 November, so rate expectations will move with this week’s data rather than a decision.

03 Why it moved — oil, US yields and election polls
The main pressure came from abroad. Higher oil prices revived inflation worries and pushed investors towards safer assets. The US 10-year Treasury yield rose about 8 basis points to 5.244%. The S&P 500 fell 0.77%, the Nasdaq 0.92% and the VIX fear gauge jumped 8.07%.
Rate-sensitive banks took the brunt at home. Itaú fell 1.00%, Bradesco 1.23%, Banco do Brasil 0.46% and BTG Pactual 0.72%. The exchange operator B3 lost 1.67%.
Oil producers limited the damage. Petrobras preferred shares rose 1.35% and its common shares 1.83%. PRIO gained 3.84%, and Vale added 0.55%.
Election polling added to the cautious tone. BTG Pactual/Nexus showed Lula leading Flávio Bolsonaro 42% to 37% in the first round. In São Paulo, a Futura poll gave Governor Tarcísio de Freitas 54.8% against Fernando Haddad’s 32.6% in the state governor race.
The real’s slide was part of a regional move. The dollar gained 1.74% against the Mexican peso and 0.71% against the Chilean peso. The dollar index rose 0.22%.
04 The day’s movers
| Driver | Level / Move | Change | Note |
|---|---|---|---|
| Petrobras (PETR4) | R$48.72 (US$9.32) | +1.35% | Most traded stock; higher crude prices lifted oil names |
| PRIO (PRIO3) | R$61.63 (US$11.79) | +3.84% | Oil producer led the gainers among large caps |
| Vale (VALE3) | R$71.16 (US$13.62) | +0.55% | Mining heavyweight edged higher despite weaker metals |
| Itaú Unibanco (ITUB4) | R$41.71 (US$7.98) | −1.00% | Banks fell as US yields rose |
| Bradesco (BBDC4) | R$17.66 (US$3.38) | −1.23% | Among the weakest of the large banks |
| WEG (WEGE3) | R$50.12 (US$9.59) | −1.86% | Industrial exporter gave up Friday’s gain |
| Natura (NATU3) | R$6.71 (US$1.28) | −5.76% | Among the steepest falls in the index |
Petrobras was the session’s most traded stock and one of its main supports. Its preferred shares rose 1.35% as crude climbed. PRIO gained 3.84%, and fuel distributors Vibra and Ultrapar also rose more than 2%.
The banks went the other way. Itaú fell 1.00% and Bradesco 1.23%. Consumer and retail names were weaker still: Natura dropped 5.76% and Azzas 2154 5.25%.
05 The regional scoreboard
| Index | Country | Change |
|---|---|---|
| Ibovespa | Brazil | −0.26% |
| IPC | Mexico | −0.07% |
| IPSA | Chile | −1.06% |
| Merval | Argentina | −3.28% |
| COLCAP | Colombia | −0.33% |
Latin America’s equity markets all fell. Argentina’s Merval was the standout loser at −3.28%. Chile’s IPSA fell 1.06%, Colombia’s COLCAP fell 0.33% to 2,576, according to Acciones y Valores, and Mexico’s IPC slipped 0.07%.
The regional weakness tracked the US session, where the S&P 500 lost 0.77% and the Nasdaq fell 0.92%.
06 The technical picture
The Ibovespa failed to hold 184,000, which it briefly topped during the session. It closed at 182,991 after an intraday low of 181,931. That low is the immediate support to watch.
The index is now about 7.9% below its 52-week closing high of 198,657, set on 14 April 2026.
At 5.2255 per US dollar, the exchange rate is about 6.5% below its 52-week high of 5.5901, set in December 2025. Monday’s 0.86% rise shows the pair remains sensitive to global dollar strength and local political noise.
07 What to watch
- Domestic data: IGP-M inflation, unemployment and the Treasury’s August budget result land today; a hot inflation print would weigh on rate-sensitive banks
- Election polls: Fresh surveys before the 4 October first round are the key domestic risk for the real and state-linked stocks
- US dollar and yields: The dollar index rose 0.22% and the US 10-year yield reached 5.244%; both keep pressure on emerging-market currencies
- Oil and metals: Crude supported Petrobras and PRIO, while gold fell 3.71%; the US–Iran talks remain the swing factor for oil

Frequently Asked Questions
What is the Ibovespa?
It is Brazil’s main stock index, tracking the largest and most-traded companies on the B3 exchange in São Paulo—think of it as Brazil’s FTSE 100 or S&P 500.
Why did the Ibovespa fall on Monday?
Global risk aversion, higher US Treasury yields and weak bank shares pulled the index down 0.26%. Gains in Petrobras and other oil stocks limited the fall.
What does a weaker real mean?
It means one US dollar buys more Brazilian reais—5.2255 per US dollar on Monday, up 0.86%. A weaker real makes Brazilian imports pricier but can help exporters.
What is the Selic?
It is the Brazilian central bank’s benchmark interest rate, the main tool for controlling inflation. It stands at 13.75% after a quarter-point cut in September, and the next decision is due on 4 November.
