Brazilian President Luiz Inacio Lula da Silva has won an unprecedented fourth term, defeating Senator Flavio Bolsonaro with 51.79% of the vote against 48.21% in a runoff held this week, according to an analysis by Professor Mark Kirton, Director of the Centre for International and Border Studies, published by Demerara Waves Online News- Guyana.
The result defied every precedent in Brazilian politics. No runner-up from the first round had ever come back to win a runoff, and no candidate who lost Minas Gerais, the country's bellwether state, had ever recovered to take the presidency. Lula lost Minas Gerais by five points in the first round in early October, then flipped it 50.4% to 49.6% in the second. Abstentions also fell from a record 21.08% to 19.21%, a sign that the compressed three-week campaign mobilized voters, particularly in Lula's strongholds in the Northeast. NPR reported the win as a stunning result, with more than 96% of votes counted showing Lula above 51%.
A victory against the regional tide
Lula's win is also significant because it bucks a continental shift. Since 2025, seven presidential elections in Latin America have produced right-wing winners, and several governments have aligned themselves closely with Washington's agenda. Kirton argues that Bolsonaro's defeat denies the United States a critical right-wing ally in South America's largest economy and gives Brazil a strategic position to push back against American political and economic demands on regional states.
The victory comes with sobering arithmetic for the Workers Party (PT). Lula turns 81 this week and will be sworn in as Brazil's 40th president in January 2027. By the end of this term he will have served sixteen non-consecutive years, the longest tenure of any democratically elected Brazilian president. Kirton says the PT must now build a succession plan and move beyond dependence on a single charismatic leader who has carried it to four victories.
Lula will govern a deeply polarized country. Bolsonaro's Liberal Party increased its representation in the National Congress, and governorship races also shifted toward the right and center. CNN noted that although Bolsonaro lost, Bolsonarism remains very much alive and continues to mobilize a growing conservative movement. Negotiation and coalition-building will dominate policymaking in Brasilia for the next four years.
Why Lula's win matters for the Guyana-Venezuela controversy
For Guyana, the stakes are direct. Kirton writes that Brazil has consistently supported the inviolability of juridically settled borders and has backed the settlement of the Guyana-Venezuela border controversy through the International Court of Justice. A Lula government, he argues, can be expected to support compliance with the ICJ ruling.
But there is a caution. Given Brazil's consistent position on sovereignty, Kirton warns that any externally influenced attempt to force negotiations on the border after the ICJ judgment may not find support in Brasilia, because reopening settled borders could carry implications for Brazil's own territory. For a country facing Venezuelan claims over Essequibo, a neighbor committed to the region's status as a zone of peace is an asset Guyana should consolidate, not take for granted.
Trade, infrastructure and business openings
The commercial relationship is already bearing fruit. Guyana has recorded a trade surplus with Brazil for the first time, driven almost entirely by crude oil exports, which account for roughly 98% of Guyana's exports to its neighbor. A new Lula government is expected to accelerate bilateral infrastructure arrangements, including the long-awaited completion of the Linden-Lethem road link, alongside deeper engagement with Mercosur.
Kirton sees room for Guyanese entrepreneurs to go beyond oil. Interest from northern Brazil, especially the states of Roraima and Amazonas, is growing, and he suggests niche ventures such as Guyanese restaurants in Manaus or Boa Vista. He also points to cricket: Brazil's women's team has won four of the last five South American championships, and the men's team won the 2026 T20 South American championship in Colombia. Guyana, he argues, could provide coaching clinics, umpiring seminars and cricket management expertise, while Brazilian fans could become a new market for Caribbean Premier League matches and sports tourism.
There is also an ethanol angle. As global demand for ethanol rises, Kirton proposes that Guyanese sugar lands currently idle could host joint ventures with Brazilian producers, drawing on Brazil's decades of experience in the commodity.
A region recalibrating
World leaders have lined up to congratulate Lula on the dramatic win, though, as The Guardian reported, Flavio Bolsonaro has so far refused to concede and Donald Trump has remained silent. That silence says much about the geopolitical realignment now underway in the hemisphere.
For Guyana, the lesson is practical. Lula's Brazil offers a partner committed to multilateralism, Amazon protection, South American integration and a rules-based settlement of the border controversy. The opportunity now is to intensify and upgrade that engagement, from the Linden-Lethem road to cricket coaching in Boa Vista, while the political window in Brasilia remains open.
