Brazil stocks crash 13.9% and real plunges after Lula's surprise win

Brazil's stock market suffered one of the worst days in its history on Monday, October 26, 2026, as investors reacted to President Luiz Inácio Lula da Silva's surprise re-election. The benchmark Ibovespa index closed 13.88% lower at about 176,608 points, trading on the B3 exchange was halted for 30 minutes by a circuit breaker, and the Brazilian real lost around 11% against the US dollar at one point.

What happened

The sell-off began before Brazilian markets even opened. A US-listed fund that tracks Brazilian shares fell nearly 15% in Tokyo trading in the early hours of Monday, hours after Lula beat Senator Flávio Bolsonaro in Sunday's runoff with about 51.8% of the vote.

When the São Paulo exchange opened, selling was immediate. Once the Ibovespa had fallen 10%, the B3 triggered its circuit breaker and stopped all trading for 30 minutes — the first time this has happened since the Covid crash of March 2020. When trading resumed the losses deepened, and at its lowest point the index was down more than 17%, the largest intraday fall since 1998. A late recovery trimmed the loss to 13.88% at the close.

The numbers

Market	Before the runoff	Monday, October 26	Change
Ibovespa (close)	205,083	176,608	-13.88%
Ibovespa (intraday low)	205,083	about 169,516	about -17.3%
US dollar in reais	about 4.98–4.99	near 5.60 at its peak	real down about 11%
Trading halt	—	30 minutes at -10%	first since March 2020

Retailers, health insurers and other companies that depend on Brazilian consumers and domestic interest rates were among the hardest hit, with some shares losing more than half their value in a single session. Shares of state-controlled oil company Petrobras also fell sharply, although reports of the size of its drop differed.

Background: why markets were caught out

Flávio Bolsonaro, the son of former president Jair Bolsonaro, won the first round on October 4 with 47%, and many investors expected him to win the runoff. In the weeks that followed, Brazilian shares rose and the real strengthened as traders bet on a government they saw as more likely to cut spending and support business. Lula's come-from-behind win — he is the first first-round runner-up to win a runoff since Brazil returned to democracy in 1985 — left those positions exposed, and they were unwound all at once.

The main worry is the public finances. Brazil's government debt has been rising, and investors fear that a fourth Lula term will bring more spending and pressure on the central bank to keep interest rates lower than inflation would justify. Lula has often criticised high rates during his current term.

Adding to the uncertainty, Bolsonaro has not conceded. He has said he will ask the electoral authorities to annul the result, citing a two-hour extension of voting in some areas. Analysts say the challenge is unlikely to succeed given Lula's lead of more than four million votes.

Reactions

Currency strategists said the real could weaken further in the short term as the pre-election rally unwinds and markets focus on rising public debt, but noted that Brazil's high interest rates and commodity exports could limit the fall later. Investors are now waiting for Lula to name his economic team for the new term and to say how he will keep the budget under control.

Why it matters

A falling real makes imports more expensive and can push up inflation for ordinary Brazilians, especially for fuel and food priced in dollars. It also raises the cost of servicing dollar debts for Brazilian companies. Brazil is Latin America's largest economy and a major exporter of soybeans, coffee, sugar, iron ore and oil, so moves in the real ripple into global commodity prices — coffee and sugar futures fell on Monday as the weaker currency encouraged Brazilian farmers to sell.

For emerging markets, including Pakistan and India, a crash of this size is a reminder of how quickly foreign money can leave when an election result surprises investors.

What happens next

Markets will watch whether the Ibovespa and the real stabilise on Tuesday, any statement from the finance ministry and the central bank, and Lula's choice of finance minister. The central bank's next rate decision, the Bolsonaro camp's legal challenge, and Lula's first speeches on fiscal policy will shape the weeks ahead. Lula's fourth term begins on January 5, 2027.
