South America’s Oil Export Rise Changes the Market Math During Hormuz Disruption
Brazil, Guyana and Venezuela are reshaping crude supply flows as Middle East shipments face pressure.
NEW YORK | South America is becoming a more important crude-oil supplier at the exact moment markets are most focused on disruptions tied to the Strait of Hormuz.
Reuters reported that Brazil, Guyana and Venezuela have delivered significant year-over-year export gains in 2026, helping South America post the largest increase in crude exports among producing regions so far this year.
The shift does not replace Middle East supply. Reuters reported that the near-total closure of the Strait of Hormuz has created a much larger gap than any one region can quickly fill. But the additional barrels from South America are enough to change trading routes, tanker demand and the strategic importance of Atlantic Basin supply.
Brazil remains the region's largest exporter, while Guyana's growth has been especially rapid since it began exporting oil in 2020. Those volumes matter because they provide refiners with non-Middle East supply options when the Gulf becomes more difficult or expensive.
Market participants should be careful not to treat the region as a quick fix. Production growth requires investment, infrastructure, political stability and export capacity. But the direction is clear: South America is moving from a secondary supply story to a central market variable.
The market math now includes not just OPEC+, U.S. shale and Gulf transit, but Brazil, Guyana and the broader South American export system.

What this means
For consumers and companies, extra supply can help cushion shocks, but it cannot fully erase the cost of a major chokepoint disruption. The strategic role of South American barrels is likely to keep growing.
