The Three LatAm Countries Now Driving Half the World’s New Oil Supply, Led by Brazil

Key Points

• Brazil will pump over 4.2 million barrels of oil per day in 2026, leading a Latin American surge that now supplies more new oil to the world than any region outside the Middle East.
• Three countries — Brazil, Argentina and Guyana — are adding 700,000 barrels per day this year while Venezuela, despite sitting on the planet’s largest reserves, faces a decade-long recovery after the fall of Maduro.
• The boom collides head-on with climate politics: Brazil is expanding drilling toward the Amazon while simultaneously hosting the world’s most important climate summit.

Somewhere beneath the Atlantic, about 300 kilometres off the coast of Rio de Janeiro, oil sits trapped under kilometres of rock, water and ancient salt.

Getting to it once seemed impossible. Today, it powers one of the most consequential energy shifts happening anywhere on Earth.

Brazil’s pre-salt oil fields — so named because they lie beneath a thick salt layer, five to seven thousand metres below the ocean surface — now produce nearly 80 per cent of the country’s oil.

In 2025, national output shattered records at 4.9 million barrels of oil equivalent per day, up 13 per cent from the year before.

One single platform, the Almirante Tamandaré — as tall as five Christ the Redeemer statues — pumps over 250,000 barrels daily by itself.

Latin America reshapes global oil supply

Petrobras, the state oil giant, is investing $98 billion through 2029, with breakeven costs below $40 a barrel, making this oil profitable even when prices crash.

Brazil is not alone. Argentina’s Vaca Muerta shale formation — only four per cent tapped, holding an estimated 16 billion barrels — saw production jump 30 per cent last year.

Guyana, a nation smaller than many cities, went from zero oil output to 900,000 barrels per day in under a decade after ExxonMobil struck 11.6 billion barrels offshore.

Together, these three countries now drive half of all new global crude supply growth. Then there is Venezuela. It owns more oil reserves than any country on Earth — 17 per cent of the global total — yet produces barely one per cent.

Decades of mismanagement under Chávez and Maduro gutted the industry. After Maduro’s capture in January, the new government opened the sector to private investment and Washington eased sanctions, but analysts estimate rebuilding to meaningful levels will take a decade and tens of billions of dollars. The Big Three are not waiting.

This matters far beyond South America. When Latin America adds oil at this pace outside OPEC+ quotas, it reshapes what you pay for fuel, how energy-importing nations secure supply, and which governments gain leverage.

Conservatives cheer the geopolitical win of Western-hemisphere barrels replacing Russian and Middle Eastern dependence.

The left and environmental groups see a dangerous contradiction: Brazil approved oil exploration at the Amazon’s mouth — 30 new blocks overlapping biodiversity zones — while preparing to host COP30, the UN climate summit, in Belém.

Petrobras counters that pre-salt crude emits up to 70 per cent less CO2 per barrel than the world average. Critics call it greenwashing at industrial scale.

The numbers do not take sides. They simply confirm that Latin America’s oil boom is locked in, economically resilient, and impossible to ignore — whether you see it as progress or peril.
