How the War in Iran is Skyrocketing Revenues for Guyana, the World's Newest Petrostate

While many nations grapple with the inflationary pressures and food supply threats stemming from the conflict in the Middle East, Guyana, the world's newest petrostate, finds itself in a unique position. The ongoing tensions involving Iran and the resulting disruption to the Strait of Hormuz have unexpectedly supercharged the South American nation's burgeoning oil sector, leading to a dramatic surge in its revenues, as detailed by El Nacional.

This windfall is a result of a dual effect: the planned increase in Guyana's crude oil production and the significant rise in global oil prices directly linked to the geopolitical situation. Sidney Armstrong, a professor at the University of Guyana's Economics Department, notes that production has climbed past 920,000 barrels per day and is expected to rise further. Simultaneously, benchmark Brent crude prices have soared from around US$62 to approximately US$108 per day since the conflict began, according to the U.S. Energy Information Administration.

Guyana is a case interesting since it has become the fastest-growing economy in the world. In large part, this is because it starts from a really very small base, but it is still the economy that is growing the fastest.

Guyana's oil story is remarkably recent, with hydrocarbon production beginning only six years ago. Yet, this short period has propelled it to become a major South American oil producer and, according to Roxanna Vigil of the Council on Foreign Relations, the world's fastest-growing economy. The World Bank reports an average annual economic growth of 40.9% since 2020, largely fueled by these oil revenues, which constituted 37% of the state budget in 2025, amounting to approximately US$2.5 billion.

The conflict in Iran and the blockade of the Strait of Hormuz have dramatically altered Guyana's financial projections. Initial estimates for 2026 revenues were around US$2.8 billion. However, figures from The Economist suggest that weekly oil revenues have jumped by US$370 million since the war began, reaching US$623 million. This surge is expected to increase government revenues by US$4 billion for the year compared to early 2026 estimates. While this influx of wealth presents an unprecedented opportunity for development, the government, led by President Irfaan Ali, must navigate the complexities of managing these resources effectively and ensuring they benefit the nation broadly, a challenge often faced by resource-rich countries.

Due to higher global oil prices, we expect government revenues to increase by US$4 billion during the year, compared to early 2026 estimates.
