Brazilian Markets Plunge After Lula’s Re-election Victory

President Luiz Inácio Lula da Silva’s re-election victory prompted a sharp reversal in financial markets that had expected his opponent to win.

· Brazil’s benchmark Bovespa Index plunged 14%, its worst single-day fall since March 2020, triggering a 30-minute trading halt.

· The Brazilian real weakened by over 8% against the US dollar, while government bond yields surged amid investor concerns.

· Markets reversed earlier gains as investors had expected right-wing candidate Flávio Bolsonaro, considered more market-friendly, to win the election.

· The unexpected result triggered a rapid unwinding of pre-election investment positions and heightened market volatility.

· Argentina experienced spillover effects, with its 10-year dollar-denominated bond yield rising by 0.4 percentage points, while US markets remained largely stable.

· Investors will closely monitor cabinet appointments, the role of Vice President Geraldo Alckmin, coalition dynamics and the new administration’s fiscal strategy.

Stocks in Brazil plummeted on Monday (26.10.2026) after President Luiz Inácio Lula da Silva’s re-election victory and his opponent’s early dispute of the results.

The Bovespa Index, Brazil’s benchmark stock index, quickly fell more than 10 percent as trading began, triggering a 30-minute circuit breaker — a tool that pauses trading to prevent runaway sell-offs. The index ended the day 14 percent lower, its worst fall since the onset of the pandemic in March 2020.

The country’s currency, the real, weakened significantly, down more than 8 percent against the dollar, on course for its sharpest single day weakening against the dollar since early 1999.

The new government’s cost of borrowing rose sharply, with the yield on Brazil’s dollar-denominated 10-year government bond rising more than 0.2 percentage points to around 6.45 percent. Its local-currency 10-year bond yield rose even more, up more than two full percentage points to around 15 percent.

The moves were a sharp reversal, after stock prices rose over the past few months and bond yields trended lower, as investors began to bet on Mr. Lula’s opponent, Flávio Bolsonaro, clinching victory. Mr. Bolsonaro, the right-wing candidate, had aligned himself with President Trump and had been seen as the more market friendly of the two candidates.

“Brazilian assets are likely to face immediate pressure and heightened near-term volatility as market unwinds positions built on expectations of a Bolsonaro victory,” said Dev Ashish, an economist focused on Latin America at Société Générale, a French bank.

There was little early sign of the moves affecting markets in the United States. Major indexes ended the day higher, and the 10-year Treasury yield moved slightly lower.

Argentina did appear to feel some spillover. Argentina’s dollar-denominated 10-year yield rose 0.4 percentage points. Mr. Ashish noted that much of the ferocious volatility on Monday reflected the rapid unwind of pre-election bets.

“Once the initial volatility subsides, market attention will likely shift to cabinet appointments,” he said, “particularly whether Vice President Geraldo Alckmin assumes a leading economic role, the influence of centrist congressional parties within the governing coalition, and the administration’s broader fiscal strategy.”
