Brazil is preparing for a presidential runoff election on October 25 after right-wing candidate Flávio Bolsonaro secured a narrow lead in the first round of voting held on October 1. Bolsonaro, the son of former President Jair Bolsonaro who is currently imprisoned, received approximately 47 percent of the vote, surpassing incumbent Luiz Inácio Lula da Silva, who garnered around 45 percent. Neither candidate achieved the required 50 percent majority to win outright in Latin America’s largest economy, setting the stage for a decisive second round.

Bolsonaro’s unexpected first-round performance exceeded most opinion polls and placed him in a stronger position heading into the runoff, with analysts noting that no first-round runner-up has succeeded in defeating the incumbent since Brazil’s return to democracy in the 1980s. His Liberal Party also made significant gains in legislative and gubernatorial races, signaling a broader rightward shift among Brazilian voters amid rising political polarization.

Investors responded positively to Bolsonaro’s performance, driving a surge in Brazil’s financial markets. The Brazilian real strengthened by nearly 5 percent against the U.S. dollar, while the main stock index jumped roughly 9 percent. Bond yields also fell, reflecting market optimism that Bolsonaro would implement market-friendly reforms. Economic analysts highlight concerns over Brazil’s public debt, which stands at more than 80 percent of GDP, and elevated interest rates near 13.75 percent. They expect Bolsonaro to pursue rapid fiscal consolidation aimed at narrowing the budget deficit and creating conditions for lowering borrowing costs, which have strained businesses and consumers.

The presidential race is also receiving international attention due to its potential implications for Brazil’s foreign relations, particularly in the context of increasing competition between the United States and China. Bolsonaro is generally seen as favoring closer ties with the United States and has expressed support for U.S. strategic interests in the region, including cooperation on developing Brazil’s rare earth mineral resources. He has already met with former U.S. President Donald Trump and indicated a willingness to join initiatives such as the “Shield of America,” an alliance aimed at combating drug trafficking and reducing Chinese economic influence in Latin America.

In contrast, Lula, who is seeking a fourth consecutive term and enjoys longstanding political influence, has emphasized strengthening relations with China, Brazil's largest trading partner since 2009. China accounts for nearly 30 percent of Brazil’s total trade, significantly more than the roughly 12 percent represented by U.S. trade. Under Lula, Brazil has expanded exports of commodities like soybeans, crude oil, and iron ore to China and deepened participation in multilateral groupings such as BRICS. Chinese investments in Brazil have also surged in recent years, spanning sectors from mining to automotive manufacturing and technology infrastructure.

Despite divergent foreign policy orientations proposed by the candidates, economic interdependence with China is expected to persist regardless of who wins the runoff. Bolsonaro has indicated a pragmatic approach toward economic ties with China, mirroring his father’s previous pragmatic engagement despite political criticisms. Similarly, other recent right-wing leaders in South America who have allied with the U.S. have maintained or even sought to enhance trade relations with China.

The runoff election will thus not only decide Brazil’s domestic political direction but also shape the strategic dynamics between major global powers in the Western Hemisphere. The next president will inherit challenges that include managing a large public debt, reining in inflation, and navigating a complex geopolitical landscape influenced by U.S.-China rivalry. The new term is scheduled to begin in January 2027.
