Missing Ring-Fence in Guyana’s Oil Deal May Cost Billions, Civil-Society Groups Warn

Energy: Guyana

A missing accounting safeguard in Guyana’s oil contract with ExxonMobil lets costs from new Stabroek Block projects eat into profits from fields already pumping near full capacity, and Guyanese analysts say that gap has already cost the country billions of dollars it will not get back.

The Ring-Fencing Gap Explained

Ring-fencing is a standard safeguard in petroleum contracts that keeps each oil field’s costs and revenues separate for accounting purposes, so losses or spending in one field cannot be charged against profits earned in another. Stabroek News has described the mechanism plainly: it “involves separating financial aspects of different projects, shielding profits of one segment from the risks of another” (Stabroek News).

Guyana’s 2016 Stabroek Block Production Sharing Agreement (PSA) with the ExxonMobil-led consortium contains no such clause. Vice President Bharrat Jagdeo has repeatedly listed its absence as one of the deal’s core defects, alongside “no corporate tax, only 2 per cent royalty to the State and a secret US$18 million signing bonus” (Department of Public Information, Guyana).

Without a ring-fence, the consortium can apply up to 75% of monthly block-wide revenue toward “cost oil” recovery for any Stabroek field, including new projects that have not yet produced a barrel, before the remaining “profit oil” is split 50/50 with the government. Kaieteur News summarized the effect bluntly: “In the absence of ring-fencing, Exxon takes 75% of all the oil produced to pay for projects that are still to startup” (Kaieteur News).

The $4 Billion Loss Estimate

The multibillion-dollar loss figures attached to Guyana’s ring-fencing gap did not come from the International Monetary Fund or the Inter-American Development Bank. They trace to the Guyanese civil-society Oil and Gas Governance Network (OGGN) and chartered accountant Christopher Ram, whose year-by-year models compare Guyana’s actual profit-oil receipts against what the country would have earned under a ring-fenced structure.

For 2024, OGGN calculated that Guyana’s Bank of Guyana-reported profit share of US$2.2 billion should instead have been about US$6.4 billion under ring-fencing, a forfeiture of roughly US$4.2 billion, or about US$5,250 per citizen (OGGN). For 2025, using updated production and price data, Kaieteur News reported the same methodology showed a forfeiture of roughly US$4.9 billion, as Guyana’s actual profit share of US$2.1 billion compared with an estimated US$7 billion under ring-fencing (Kaieteur News).

The IMF’s own July 2026 Article IV mission to Guyana made no reference to a ring-fencing loss figure; its published statement urges Guyana to “continue strengthening audit capacity, especially in oil and gas sector,” and to resolve ExxonMobil cost-oil audit disputes “in a timely manner” (IMF). The roughly $4 billion figure attached to this story is best understood as an independent Guyanese analyst estimate, not an institutional one.

ExxonMobil’s Stabroek Contract

The Stabroek Block is operated by ExxonMobil Guyana (45%), alongside Chevron, which inherited Hess Corporation’s 30% stake, and CNOOC (25%). Output has climbed from roughly 120,000 barrels per day in late 2021 to a record 918,000 barrels per day in February 2026 across four producing vessels, with two more projects, Uaru and Whiptail, expected online in 2026 and 2027 (OilNOW).

Reuters reported on July 31, 2026 that the ExxonMobil-led joint venture has now recovered the roughly $55 billion it invested in Stabroek, about two years faster than expected, a milestone that will shift more revenue toward the 50/50 profit split going forward. Exxon Chief Financial Officer Neil Hansen said, “We brought these investments on at an unprecedented pace and cost advantage” (Reuters).

Even so, ExxonMobil has applied for an eighth and ninth Stabroek project, and neither carries a ring-fencing condition, according to Kaieteur News, meaning any new development could again draw down shared revenue before Guyana’s full 50% share becomes the norm (Kaieteur News). ExxonMobil Guyana President Alistair Routledge has ruled out reopening the contract’s terms: “We have no interest to invoke that article. As I say, we’ve made US$55 billion worth of commitment to the country. To go back and to undermine the basis of that investment would seriously challenge any future investments” (Kaieteur News).

Guyana’s Negotiating Leverage

President Irfaan Ali has repeatedly refused to touch the 2016 PSA, telling an audience at Rice University’s Baker Institute in May 2026 that “the sanctity of contract is important for us” and that reopening the deal “could result in a legal hurdle of an unimaginable scale” (Kaieteur News). In a BBC interview he acknowledged the deal’s shortcomings directly: “The deal could have been better for Guyana. Exxon had a good deal signed by the last government but, look, for us, the sanctity of contract is very important. We cannot go back and renegotiate” (OilNOW).

Vice President Jagdeo has framed the trade-off as deliberate rather than accidental, arguing that forgoing ring-fenced revenue now speeds up overall development: “We admitted that we are foregoing revenue now in exchange for massive future income… trying to grab this bone now could cause you to lose all the bones, the bigger bones too in the future” (Kaieteur News).

Guyana’s real leverage lies not in reopening Stabroek’s terms but in its licensing power over new projects. The government has already written ring-fencing into its model PSA for blocks outside Stabroek, alongside a higher 10% royalty, a lower 65% cost-recovery ceiling and a new 10% corporate tax (Department of Public Information, Guyana). Whether Georgetown attaches similar conditions to ExxonMobil’s pending eighth and ninth Stabroek applications is the clearest test of how much of the ring-fencing debate translates into actual policy.

Regional Oil-Diplomacy Stakes

Guyana’s handling of the Stabroek contract carries weight well beyond its own budget. With reserves estimated above 11 billion barrels of oil equivalent and output pushing toward 1.7 million barrels per day by 2030, the country has become one of the fastest-growing economies in the world and a live case study for how small, oil-rich states negotiate with supermajors (Reuters).

Washington has signaled it does not want Georgetown to reopen the deal. A visiting U.S. Under Secretary for Economic Affairs, Jacob Helberg, said in May 2026 that he found “perfect alignment” between President Ali and ExxonMobil Guyana, pushing back on growing domestic pressure for renegotiation (MarketScreener). That stance keeps Guyana’s political opposition, which campaigned in 2025 on renegotiating the PSA and adding ring-fencing protections, on the outside of the current policy consensus (Stabroek News).

The dispute also intersects with Guyana’s border standoff with Venezuela over the Essequibo region and Stabroek acreage under force majeure pending an International Court of Justice ruling, meaning fiscal fairness questions inside the contract are unfolding alongside a live territorial dispute just offshore. How Guyana balances contract sanctity, revenue capture and regional diplomacy over the next few years will likely shape how other emerging oil producers approach their own supermajor negotiations.

Frequently Asked Questions

What does “ring-fencing” mean in Guyana’s oil contract?

Ring-fencing would require each Stabroek Block field’s costs to be recovered only against that field’s own revenue, rather than against the combined revenue of the whole block. Guyana’s 2016 PSA has no such clause, so ExxonMobil and its partners can use revenue from producing fields to cover costs on new, not-yet-producing projects (Stabroek News).

Who calculated the roughly $4 billion loss figure?

The figure comes from Guyana’s Oil and Gas Governance Network and chartered accountant Christopher Ram, who estimated forfeitures of about $4.2 billion in 2024 and $4.9 billion in 2025 due to the absence of ring-fencing, as reported by Kaieteur News. It is not an IMF or IDB estimate (Kaieteur News).

Will Guyana renegotiate the ExxonMobil contract?

No. President Irfaan Ali has repeatedly ruled out renegotiating the 2016 Stabroek PSA, citing “sanctity of contract,” and ExxonMobil Guyana President Alistair Routledge has said the company has “no interest” in reopening it. Guyana has instead applied ring-fencing and other tougher terms only to new oil blocks outside Stabroek (Kaieteur News).
