Lula Secures 51.79% in Brazil Runoff as Conservative Bloc Gains Congressional Ground

Brazilian voters delivered a split mandate to the country’s leadership on Sunday, electing President Luiz Inácio Lula da Silva to a fourth term while granting the conservative opposition a commanding presence in the legislature. The result complicates the path for fiscal reform and leaves markets navigating a government that lacks a unified ideological base in Brasília.

Lula captured 51.79% of valid ballots, a margin of more than 4.4 million votes over challenger Flávio Bolsonaro. The final tally stood at 64,256,232 votes for Lula and 59,826,041 for Bolsonaro. This victory represents a reelection for Lula, who trailed in the first round, but it does not guarantee control over the nation’s budget or institutional changes.

The congressional election shifted power toward the right. Bolsonaro’s Liberal Party won 121 seats in the lower chamber and 28 seats in the Senate. Gilson Schwartz of the University of São Paulo estimates that the broader right now holds approximately 59% of the Chamber of Deputies. Schwartz described the outcome as a divided government rather than a left-wing political regime, noting that voters supported Lula for social protection while backing conservative candidates on issues like crime and taxes.

Market reaction to the split outcome was sharp. The Ibovespa index closed 13.88% lower on Monday, with trading temporarily halted during the session. The dollar gained more than 8% against the real. Igor Barenboim, a former Brazilian secretary of economic policy, attributed the volatility to traders unwinding positions taken after Bolsonaro led the first round. He noted that money had flowed into Brazilian assets based on expectations of a government change that did not materialize.

The fiscal outlook remains a central concern for investors. Barenboim estimated that government debt rose from about 72% to 83% of gross domestic product during Lula’s previous term. With potential growth hovering around 2% annually and a primary deficit close to 0.5% of GDP, the nominal deficit is roughly 9% when high real interest rates are included. Barenboim warned that the government’s demand for credit tightens financial conditions for private companies, reducing the number of viable investment opportunities.

Political dynamics will further constrain the president’s agenda. Congress can block large spending packages but also demands funding for district projects. Barenboim rejected the idea that a conservative legislature would automatically impose fiscal discipline, stating that lawmakers prioritize sending money to their constituencies. He expects Lula to pursue limited consolidation by withdrawing tax breaks rather than cutting spending, a strategy he described as muddling through.

Flávio Bolsonaro traveled to the United States by Tuesday, two days after losing the election. He refused to concede immediately, initially seeking to annul the vote due to extended polling times in some areas. Only about 34,300 ballots were cast after the original closing time, a fraction of Lula’s winning margin. Bolsonaro’s Liberal Party later accepted the result announced by the Superior Electoral Court. Bolsonaro has since shifted his argument to claim the Lula ticket abused political and economic power.

International relations add another layer of complexity. President Donald Trump questioned the Brazilian result without presenting evidence of fraud. A senior US official confirmed that Bolsonaro and his family would be granted visas, though Washington did not announce asylum. Schwartz noted that this move adds friction to a relationship already strained by trade disputes and critical minerals interests. He emphasized that sovereignty is the red line for Brasília.

Regional leaders have acknowledged Lula’s victory, including presidents from Chile, Peru, Ecuador, and Colombia. These governments maintain practical needs for cooperation on border security, energy, and infrastructure. The diplomatic relationship with Israel also faces a chill. Lula has accused Israel of genocide in Gaza and supports Palestinian statehood, contrasting with Bolsonaro’s pledge to move the Brazilian Embassy to Jerusalem.

Trade flows between Brazil and Israel continue despite the diplomatic distance. Brazil sold about $569 million in goods to Israel in 2025 and purchased roughly $1.3 billion in return. Agricultural sales from January through September 2026 have already exceeded the full-year 2025 figure. The exchange includes food, fertilizer, machinery, technology, and medical equipment. Neither country currently has an ambassador posted in the other’s capital, but commercial ties remain active as the new term begins.
