The Real Firmed 1.8% to 4.97 per Dollar on the Friday Before Brazil's Runoff, Then Gave Some Back Overnight (October 2026)
Brazil votes in a presidential runoff on Sunday, October 25, 2026. On Friday the real strengthened from 5.063 per dollar on Binance's USDT/BRL pair to a low of 4.9739 at 21:00 UTC, a 1.8% move, with most of it in the São Paulo session. Late in the evening the pair swung back above 5.03, and it spent the weekend near 5.01. Replay how a currency prices an election it cannot yet know.
The first round on October 4, 2026 put Flávio Bolsonaro ahead of President Luiz Inácio Lula da Silva, 47.03% to 45.16% of valid votes, when polls had expected Lula to lead. The next day the Ibovespa rose 7.7% to a record and the real gained about 4%, with the central bank's PTAX reference rate at 4.9859 per dollar. Three weeks later the final polls showed a near tie, Datafolha and Quaest at 51% to 49% for Bolsonaro among valid votes, and the real had drifted back above 5 per dollar: Binance's USDT/BRL pair, which tracks the dollar-real rate through a dollar stablecoin, closed October 22 at 5.0634.
Friday's move happened in Brazilian hours. The Asian and European mornings were flat, between 5.054 and 5.059. At 12:00 UTC, 9 a.m. in São Paulo, when the local currency market opens, volume jumped from $1.8 million in the 11:00 hour to $29.3 million and the pair fell 0.28%; by the 17:00 UTC hour, on $61.8 million, it was down to 5.0126, and it crossed below 5.00 in the 19:00 hour. The low of 4.9739 came in the 21:00 UTC hour, after the Brazilian market had closed, 1.77% below the start of the day.
The same hour showed how thin the market had become. The 21:00 candle traded between 4.9739 and 5.0465, a range of 1.5% on $19.9 million, and the 23:00 hour rose 0.34% to 5.0165 as some of the day's buyers of reais sold before a weekend with an election in it. The pair closed Friday's UTC day at 5.0165, about 0.9% stronger for the real than Thursday, and traded between 4.997 and 5.017 on Saturday and early Sunday, near 5.01.
Two lessons are in this chart. A currency before an election prices probabilities, not outcomes: a move of 1.8% in a day, followed by a partial reversal into the weekend, is what traders do when a result is close and the cost of being wrong over two days of closed local markets is high. And the 23:00 bounce is the kind of move that happens when positions are squared rather than opened. On October 5, the first trading day after the first round, the real moved about 4% in a session; whatever the runoff decides, the first prints on Monday are likely to be larger than anything in this replay.
