For most of the 20th century, Guyana was one of South America's overlooked economies — a jungle-blanketed nation of roughly 850,000 people, dependent on sugar, timber, and gold, and among the region's lowest-ranked countries by income per capita. That identity has been dismantled with startling speed. Today, Guyana is one of the fastest-growing economies on earth, and on certain purchasing-power measures, its income per person has surpassed that of the United States. This is not a story of gradual development. It is a rupture.
The Drillbit That Changed Everything
The transformation can be traced to a single announcement. On May 20, 2015, ExxonMobil affiliate Esso Exploration and Production Guyana announced it had encountered more than 295 feet of high-quality oil-bearing sandstone at the Liza-1 well, drilled approximately 120 miles offshore in the Stabroek Block. It was the first exploration well the company had drilled there after years of collecting 3D seismic data across the 6.6 million-acre prospect, a campaign ExxonMobil described as the largest proprietary seismic effort in its history.
Commercial extraction from the Liza Phase 1 development commenced on December 20, 2019 — ahead of schedule and in under five years from the initial discovery, well below the deepwater industry average of nine years. ExxonMobil CEO Darren Woods marked the event by describing it as a "historic milestone" for "quality and leadership in project execution."
From First Find to Offshore Powerhouse
By the close of 2019, the Stabroek consortium and other operators had confirmed approximately 18 offshore discoveries across Guyana's blocks — a total that has since expanded dramatically. ExxonMobil now places the Stabroek Block's recoverable resource base at approximately 11 billion oil-equivalent barrels — a figure that CEO Darren Woods has called "unmatched" in modern history, and which accounts for more than 11% of all conventional oil discovered globally since 2015.
The block is operated by ExxonMobil with a 45% interest, alongside Hess Guyana Exploration (30%), now a subsidiary of Chevron Corporation, and CNOOC Petroleum Guyana (25%). Four floating production, storage and offloading vessels — Liza Destiny, Liza Unity, Prosperity, and ONE GUYANA — are currently operating offshore. By February 2026, daily output reached approximately 918,000 barrels, placing Guyana among the top 20 oil producers worldwide — a country that, barely a decade earlier, exported rice and bauxite.
Numbers That Defy Comparison
The economic data reads less like a development report and more like a science-fiction scenario. According to the World Bank, Guyana's economy averaged 47.6% annual real GDP growth over the three calendar years following the start of oil production. Finance Minister Ashni Singh confirmed that overall GDP grew 19.3% in 2025, with the non-oil economy expanding 14.3% in the same period. The 2026 budget projects a further 16.2% overall expansion, with oil sector output forecast to grow 17.9%.
Nominal GDP has ballooned from approximately $5 billion in 2018 to a projected $33.96 billion in 2026, according to IMF estimates — a near sevenfold expansion in under eight years.
The Per-Capita Surge
Perhaps the most striking transformation is at the per-person level. Using constant 2021 international dollar purchasing-power measures tracked by Our World in Data, drawing on World Bank estimates, Guyana's GDP per capita — which hovered around $13,000 in 2019 — has climbed past $80,000, surpassing the United States, Germany, and the United Kingdom and landing behind only Switzerland and Norway in that specific metric. By the IMF's current international dollar measure, Guyana's PPP per capita reached $95,477 in 2026, ranking tenth globally.
War in Iran and a New Energy Order
A powerful external accelerant arrived in late February 2026, when a US-Israeli military conflict with Iran triggered one of the largest energy disruptions in modern history, according to Reuters reporting. With roughly one-fifth of global oil trade transiting the Strait of Hormuz, buyers in Asia and Europe scrambled to secure crude from outside the Persian Gulf corridor. Guyana's Atlantic offshore production, unconstrained by any regional chokepoint, became strategically attractive almost overnight.
The revenue math shifted accordingly. Crude prices rose roughly 30% from the outbreak of the conflict, and Guyana's government now projects $6.5 billion in oil-related income for 2026 — more than double the estimate in place at the year's start. According to the U.S. Energy Information Administration, the United States was importing an average of 261,000 barrels per day from Guyana in April 2026 — nearly seven times the volume it imported from the country just four years earlier.
How Georgetown Is Managing the Windfall
Guyana has not treated oil income as immediate spending money. All revenues from offshore production flow first into the Natural Resource Fund, the country's sovereign wealth vehicle held at the Federal Reserve Bank of New York. By September 2025, the fund held a market value of approximately $3.6 billion, equivalent to about 12% of GDP. For the 2025 budget, the government authorized a withdrawal of $2.46 billion — the largest single allocation since the fund's creation — directed at healthcare, education, infrastructure, and agriculture.
The reinvestment appears to be generating secondary growth. Non-oil GDP expanded 14.3% in 2025, with construction among the leading sectors, rising an estimated 25.4% on Finance Minister Singh's budget figures. Oil revenues funded 37% of Guyana's national budget in 2025, the highest proportion ever recorded.
Warnings Beneath the Boom
Not every indicator points upward. Oil and gas now represents the dominant force in Guyana's GDP, and the country faces a paradox: it exports crude oil but currently lacks the domestic refining capacity to convert it into gasoline and diesel, leaving it exposed to elevated global prices for refined fuel products. President Ali has acknowledged publicly that the windfall from higher oil prices is partly eroded by higher energy import costs for ordinary consumers.
Skilled labor shortages and rising living costs continue to frustrate both government service delivery and private sector activity. The country's total population of roughly 850,000 means that any investment translates into dramatic per-capita numbers on paper — but the distribution of that wealth across a population still navigating poverty in rural areas and along the coastline remains uneven.
The Models: Norway or Venezuela?
The model Guyana's leadership most openly aspires to emulate is Norway, where a sovereign fund, fiscal discipline, and investment in non-oil sectors converted energy wealth into broad, lasting prosperity across generations. The cautionary tale is directly next door: Venezuela, a country with abundant reserves that descended into economic and political collapse when institutions could not withstand the pressure of petroleum dependency. Whether Guyana's relatively young democratic institutions can channel sudden, massive resource wealth without fracturing along the country's historical ethnic and geographic divisions remains the central, unanswered question of this remarkable economic story.
