Brazil heads to the polls on Sunday to settle the tightest presidential race in its modern history, and the outcome will reach far beyond Brasília: it will shape the direction of Latin America’s largest economy and define how one of the world’s biggest democracies deals with Washington.

President Luiz Inácio Lula da Silva, 80, is fighting for a fourth term. His challenger is Senator Flávio Bolsonaro, 45, the eldest son of jailed former president Jair Bolsonaro, running in his first national race. Three weeks ago, in the first round, Bolsonaro finished ahead with 47% of valid votes to Lula’s 45% – a gap of roughly 2.2 million votes, the narrowest first-round margin Brazil has ever recorded. A record 21% of voters stayed home.

Final polling released on Saturday shows the runoff effectively tied. Two separate surveys gave Bolsonaro a two-point edge; the closely watched Datafolha institute put the race at 51% to 49% for Bolsonaro among valid votes, within its margin of error, and found the two men almost equally unpopular – 46% of voters say they would not vote for Lula under any circumstances, 45% say the same of Bolsonaro. Pollsters describe Sunday as a coin flip decided by turnout.

What it means for the economy

Markets have already shown their preference. When Bolsonaro unexpectedly topped the first round on October 4, Brazil’s stock index jumped more than 8% in a day, the real gained 4% against the dollar, and foreign investors poured a record 10.6 billion reais into Brazilian stocks in a single session, pushing the benchmark index above 200,000 points for the first time. Investors expect a Bolsonaro government to pursue spending cuts and fiscal reform.

That early euphoria has cooled into caution as the race tightened, and economists note the fiscal math is punishing under either winner. Projections compiled before the vote see Brazil’s public debt peaking near 90% of GDP around 2032 under a Bolsonaro administration, versus roughly 95% by 2034 under current policy. Stabilizing the debt under any scenario requires a fiscal effort of at least 2.5% of GDP – meaning budget restraint is coming no matter who takes the oath in January.

Lula has campaigned on protecting social programs and raising taxes on the wealthy, arguing that growth and jobs will repair the public finances. Bolsonaro has promised to shrink the state, privatize state assets and reopen Brazil to foreign capital.

The Washington factor

The election also lands in the middle of an open trade fight with the United States. In July, President Donald Trump imposed tariffs of up to 37.5% on hundreds of Brazilian exports. Lula answered in August by triggering a formal reciprocity process that could lead to counter-tariffs, while also picking up the phone: he and Trump spoke for over an hour on August 21, and the two governments agreed to restart trade negotiations between Brazil’s industry minister, Márcio Elias Rosa, and US Trade Representative Jamieson Greer.

A Lula victory would likely mean more of the same: a left-wing government that negotiates with Washington but guards its independence, keeps close ties to China – Brazil’s largest trading partner – and resists US pressure on domestic affairs. A Bolsonaro victory would be expected to warm the relationship considerably. His father cultivated a close alliance with Trump during his presidency, and the younger Bolsonaro has signaled he would seek rapid alignment with Washington on trade and diplomacy, potentially easing the tariff standoff faster.

For Brazilian businesses, the stakes are concrete: the United States is Brazil’s second-largest trading partner and its top buyer of manufactured goods, and the tariff fight has already hit exporters of coffee, beef, steel and aircraft parts.

What happens Sunday

Some 156 million Brazilians are registered to vote. Polls open at 8 a.m. and close at 5 p.m. local time, and because Brazil votes electronically, results are expected within hours on Sunday night. Voting is mandatory, which is why both campaigns spent the final days chasing the one in five voters who skipped the first round – Lula with a rally framing the election as a last stand for his legacy, Bolsonaro urging supporters to finish the job his first-round lead started.

Whoever wins faces a divided Congress, a heavy debt load, and a trade negotiation with Washington that is only beginning.
