How the Real and Stocks Moved
The dollar came within a whisker of 5.00 reais during the session before closing at 5.019. The Ibovespa touched an intraday high of 208,941.57 and closed at 208,295.98, its highest level since 9 October, according to Agência Brasil.
The EWZ, the US-listed fund that tracks Brazilian shares, gained about 2.4% to US$42.94 in New York, according to RT data. The index also closed above its 50-day average line on the chart below.
Why Investors Bought Brazil
Globally, the dollar slipped. The DXY index, which measures the dollar against six major currencies, fell about 0.26% after weaker US housing data and bets on the path of US interest rates, according to Agência Brasil.
Brent crude, the global oil benchmark, fell 0.69% to US$108.79 a barrel on hopes of progress in US-Iran talks. Lower oil eases inflation worries worldwide, which tends to help emerging markets such as Brazil.
At home, foreign investors bought Brazilian stocks, and the market positioned itself for Sunday’s runoff between Flávio Bolsonaro, a conservative senator, and President Luiz Inácio Lula da Silva. A Real Time Big Data poll, with fieldwork from 15 to 19 October, gave Bolsonaro 52% and Lula 48% of valid votes.

What Prediction Markets Say
Polymarket, a prediction market where traders bet real money, prices a Flávio Bolsonaro win at 81.2% and a Lula win at 18.5%, with about US$189.5 million traded on the contest (20 October 2026, 6:40 p.m. ET). These prices are bets, not polls, and Kalshi, another market, is regulated in the US by the CFTC.
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.
What It Means for US Readers
A stronger real makes Brazilian assets worth more in US dollars, so the same reais of profit convert into more dollars. The real-to-dollar exchange rate also matters for travellers, because US$100 bought about 502 reais at Tuesday’s close.
Investors who follow the Ibovespa through the EWZ or ADRs such as Petrobras (PBR), Vale (VALE), Itaú (ITUB) and Nu Holdings (NU) saw the day’s gains in dollar terms. Moves driven by election positioning can reverse quickly, so the outcome on 25 October is the next test.
What Is Not Known
The closing reports do not say how much of the rally came from foreign buyers and how much from local funds. It is also unclear whether the real can hold the 5.00 level once the runoff result is known.
Published market data differs slightly by source and cut-off time. Figures here follow the B3 close and the closing rate reported by Agência Brasil.
