The Brazil election 2026 arrives with the dollar at 5.25 reais, near its highest level of the past month: the first round is this Sunday, October 4, and polls give Lula an edge over Flávio Bolsonaro, but almost all of them point to a runoff on October 25. The real will react on Monday to the result and to the make-up of Congress.
When is Brazil's election and what time are results known?
Brazil votes on Sunday, October 4, 2026. Polls close at 5:00 p.m. Brasília time, which is 4:00 p.m. in New York and 9:00 p.m. in London. Voting is electronic and the count usually finishes the same night.
It is not only a presidential race. Brazilians also elect:
- all 513 members of the Chamber of Deputies;
- 54 of the 81 senators;
- all 27 governors.
To win in the first round, a candidate needs more than half of the valid votes. If nobody gets there, the top two go to a runoff on October 25.
What do the polls say?
Polls from the last week of September show a tight race between President Luiz Inácio Lula da Silva (PT), who is seeking a fourth term, and Senator Flávio Bolsonaro (PL), son of former president Jair Bolsonaro. Ronaldo Caiado and Romeu Zema trail far behind.
| Poll | Dates | Lula | Flávio Bolsonaro | Caiado | Zema |
|---|---|---|---|---|---|
| Datafolha | Sep 28–30 | 42% | 38% | 3% | 1% |
| AtlasIntel | Sep 23–28 | 45.3% | 42.2% | 1.8% | 0.9% |
| Real Time | Sep 26–30 | 43% | 39% | 3% | 1% |
| Vox Brasil | Sep 29–Oct 1 | 40.4% | 41.2% | 3.3% | 1.3% |
First round, voting intention. Source: published polls.
On those numbers, nobody reaches 50% of valid votes. In runoff simulations the two candidates are tied within the margin of error: Datafolha had Lula at 47% versus 45% for Flávio in late September, and the latest Vox Brasil poll had Flávio at 48.2% versus 45.2% for Lula. Prediction markets, by contrast, favor Flávio.
How is the real heading into the vote?
The dollar arrives strong. USD/BRL closed Friday at 5.25, up from 5.13 in mid-September: the real has lost 2.3% in two weeks. Much of that move is not Brazilian: the dollar index rose 0.9% this week and US Treasury yields touched the 5.3% area, their highest since 2002, which pressures every emerging-market currency. The Mexican peso, for example, lost 2.6% in the same week, to 18.16 per dollar.
| Indicator | Value |
|---|---|
| USD/BRL (Friday 2 close) | 5.25 |
| Weekly range | 5.19 – 5.27 |
| 20-day / 200-day average | 5.20 / 5.23 |
| Selic rate | 13.75% (25 bp cut on September 16) |
| Next Copom meeting | November 3–4 |
The real's cushion is its interest rate. With the Selic at 13.75% and expected 2026 inflation near 5%, the real rate is around 8%, one of the highest in the world. That attracts investors who borrow in dollars to invest in reais (the carry trade) and usually limits the real's falls. The flip side is that those investors leave quickly when uncertainty rises.
What could happen to the dollar in Brazil depending on the result?
There is no way to know where the real will go, but we do know which scenarios the market is watching. What matters most is not only who wins, but what signals the result sends about the budget deficit, the main concern investors have with Brazil.
Scenario 1: a very close runoff (the most likely)
This is what almost all polls anticipate. Uncertainty drags on for three more weeks, until October 25, and the real may stay very sensitive to every new poll. In this scenario the market will focus on Congress: a Congress able to restrain spending usually reassures investors, whoever the president is.
Scenario 2: one candidate finishes well ahead
If a candidate opens a clear lead in the first round, uncertainty falls even with a runoff. The market will start pricing that candidate's economic proposals: what they say about spending, the fiscal rule and the central bank in the following days will move the real as much as the result.
Scenario 3: a first-round win
It is the least likely scenario according to the polls, because no candidate reaches 50% of valid votes. If it happened, electoral uncertainty would vanish at once and the real would trade on the winner's economic program.
The 2022 precedent
In the 2022 election, the October 2 first round also ended in a runoff, between Lula and Jair Bolsonaro. The opposition to Lula won more votes than polls suggested and Congress shifted to the right. The next day the dollar fell more than 4%, to 5.17 reais, and Brazilian stocks rose 4.79%: the market read that such a Congress would ease an agenda of less spending and intervention.
The lesson is not that it will repeat, but that the real can move 3–4% in a single day after a first round. That is three to four times its usual daily move, which is currently around 0.05 reais (about 0.9%).
Key USD/BRL levels for Monday
| Level | Price | Why it matters |
|---|---|---|
| Resistance 2 | 5.30 | Round number |
| Resistance 1 | 5.257 – 5.27 | Latest daily swing high, weekly high and upper daily Bollinger band |
| Close | 5.25 | Friday, October 2 close |
| Support 1 | 5.23 | Latest daily swing low and 200-day average |
| Support 2 | 5.19 – 5.20 | 20-day average and Wednesday 30's low |
| Support 3 | 5.10 – 5.13 | Mid-September lows and lower daily Bollinger band |
Bullish dollar scenario (weaker real): if the result raises uncertainty and USD/BRL clears 5.27 on a daily close, the next level is 5.30. Invalidation: a move back below 5.23.
Bearish dollar scenario (stronger real): if the market welcomes the result and the pair loses 5.23, it may head to 5.19–5.20 and, with a 2022-style move, to 5.10–5.13. Invalidation: a move back above 5.27.
Keep the global dollar in mind too: US ISM services comes out on Monday (10:00 a.m. New York time) and the Fed minutes on Wednesday. Everything is in today's economic calendar.
How does it affect other Latin American currencies?
The real is the region's most traded currency, and when international investors cut risk in Brazil they often do the same in other emerging-market currencies. A sharp move in the real could spill over on Monday to the Mexican peso and the Chilean peso, which already weakened this week with the global dollar (18.16 and 990 per dollar). We explain what drives each one in why is the dollar rising against the Mexican, Colombian and Chilean pesos? and in our USD/MXN guide.
How to trade an election night without blowing up your account
- Watch Monday's gap: price can open far from Friday's close and jump your stop. If you hold real positions over the weekend, size the loss for a 4% move, not for your stop.
- Wider spreads: in the first hours after an event like this, the cost of getting in and out rises. We explain it in spread, swap and slippage.
- Smaller size: if the normal move multiplies, cut your lot size to risk the same amount. The 1% rule tells you how much.

Does the dollar rise or fall in Brazil after the election?

What time does Brazil's currency market open on Monday?
Brazil's FX market opens at 9:00 a.m. Brasília time (8:00 a.m. New York, 1:00 p.m. London), although the real already trades offshore from Sunday night. The first hours are usually the most volatile.
How does Brazil's election affect the Mexican peso?
Indirectly: if investors cut risk in Brazil, they often sell other emerging-market currencies too, such as the Mexican or Chilean peso. But the Mexican peso depends more on the US and the global dollar, which already pushed it to 18.16 this week.
