Venezuela–Guyana Essequibo 2026: After Maduro's Capture, Waiting for the ICJ Ruling

WHAT CHANGED SINCE APRIL

The April edition of this briefing was built around Nicolás Maduro's campaign to annex the Essequibo, the 160,000 km² region that makes up about two-thirds of Guyana. That framing is out of date. After four months of US strikes on alleged drug boats and a naval blockade of Venezuelan oil tankers, US forces carried out strikes across Caracas on 3 January 2026 and captured Maduro and his wife, Cilia Flores. Both were flown to New York to face drug-trafficking and "narco-terrorism" charges.

Maduro's vice-president, Delcy Rodríguez, became acting president and has since governed in close coordination with the Trump administration, which formally recognised her authority in March. She has opened the oil sector to foreign companies, released political prisoners and sent crude to the United States. On Essequibo, however, she has kept Venezuela's position. She appeared in person at the International Court of Justice (ICJ) in May to reject its authority. The dispute is therefore quieter but not resolved, and its next test is the court's ruling.

TIMELINE: DECEMBER 2023 TO SEPTEMBER 2026

• December 2023: Maduro holds a referendum on creating a Venezuelan state of "Guayana Esequiba". The ICJ orders Venezuela not to change the situation on the ground.
• 2024–2025: Maduro's disputed re-election in July 2024 deepens his isolation. In 2025 Venezuela holds elections for a "governor" of Guayana Esequiba, and Guyanese soldiers come under fire on the Cuyuní river border.
• 2 September 2025: The US begins strikes on boats it says are carrying drugs from Venezuela. By 30 December more than 35 strikes have killed at least 115 people.
• October–November 2025: President Trump confirms CIA authorisation for covert operations in Venezuela. The aircraft carrier USS Gerald R. Ford arrives in the Caribbean with a force of about 12,000 personnel.
• December 2025: The US seizes Venezuelan oil tankers and on 16 December orders a blockade of sanctioned tankers. A CIA drone strike on a dock facility on 29–30 December is the first known US attack on Venezuelan soil.
• 3–5 January 2026: US strikes across Caracas; Maduro and Flores are captured. The Supreme Tribunal of Justice orders Rodríguez to act as president, treating Maduro's absence as temporary.
• January: Political prisoners are released and an amnesty law covering political offences since 1999 is passed on 30 January. A reform of the hydrocarbons law ends PDVSA's production monopoly. Venezuela begins delivering crude under a US-controlled sales arrangement.
• February–March: The US issues licences allowing oil and gas production in Venezuela, and on 12 March formally recognises Rodríguez's authority.
• 5 April: The 90-day constitutional limit for a temporary presidential absence expires. No election is called.
• 4–11 May: The ICJ holds hearings on the merits in Guyana v. Venezuela. Rodríguez tells the court that no judgment will provide "a definitive solution acceptable to both parties".
• 2–17 September: Rodríguez says elections will take place when Venezuela "is ready" but sets no date. A second round of US-backed transition talks opens in Caracas on 17 September.

THE ESSEQUIBO CASE AT THE ICJ

Guyana filed its case in March 2018, asking the court to confirm that the 1899 Arbitral Award fixed the boundary between British Guiana and Venezuela. Venezuela argues that the award was the product of collusion between Britain and the Russian presiding arbitrator, citing a posthumous memorandum by US lawyer Severo Mallet-Prevost, and that the 1966 Geneva Agreement requires a negotiated settlement instead. It traces its claim to the Spanish Captaincy General of Venezuela established in 1777.

The court ruled in 2020 and 2023 that it has jurisdiction. Oral hearings on the merits closed on 11 May 2026. Guyana's Attorney General, Anil Nandlall, expects a final, binding judgment "by or before January 2027". Many legal observers expect the court to uphold the 1899 award, since the ICJ generally treats long-accepted boundaries as settled. Venezuela has said it will not accept such a ruling, while having taken part in every stage of the proceedings.

VENEZUELA AFTER MADURO

The post-Maduro government is a continuation of the old ruling party under new terms. Rodríguez, her brother Jorge Rodríguez as president of the National Assembly, and senior figures such as Interior Minister Diosdado Cabello remain in place. The armed forces have not challenged the arrangement. The Supreme Tribunal treated Maduro's capture as a "temporary" absence, which under Article 234 of the constitution allows the vice-president to act for 90 days, extendable to 180. That limit has passed without the National Assembly declaring an "absolute" absence, which would require an election within 30 days.

The Trump administration has prioritised oil and stability over a quick election. It backs talks between Jorge Rodríguez and Dinorah Figuera, head of the opposition-elected National Assembly of 2015. Opposition leader María Corina Machado and Edmundo González, whom the opposition says won the July 2024 presidential election, are not part of the talks. Rodríguez said on 2 September that there would "without a doubt" be an election, but that "I don't set the date".

The economic opening has been significant. Under the January reform of the hydrocarbons law, foreign companies can now produce and export oil and keep the proceeds. Chevron has expanded its exports to the United States, and other PDVSA partners, including Repsol, Eni and Reliance, have applied for licences.

GUYANA: OIL BOOM AND US SECURITY

Guyana's economy has been transformed by offshore oil. Production from the Stabroek block, operated by ExxonMobil with Chevron (through its acquisition of Hess) and China's CNOOC, averaged about 911,000 barrels a day in the first four months of 2026. The start-up of the Uaru project later in 2026 is expected to lift capacity above 1 million barrels a day. Part of the Stabroek area lies off the disputed coast, which is why Venezuela's claim has direct economic stakes.

President Irfaan Ali said on 14 September that Guyana is "prepared for any reaction" to the ICJ ruling. He described the United States as having "consistently stood with us" and as coordinating regional security. Guyana takes part in the US-led "Shield of the Americas" initiative. Brazil, which borders both countries, reinforced its northern border during the 2023 crisis and has opposed any use of force.

REGIONAL CONSEQUENCES OF THE US INTERVENTION

The capture of Maduro divided international opinion. Most European and North American governments supported it; many governments in Latin America, Africa and Asia condemned it as a violation of international law. The US boat strikes of late 2025, in which at least 115 people were killed, remain legally contested. The intervention has also changed the region's security calculations. It showed that Washington is willing to use force in the Western Hemisphere, which reassures Guyana but concerns governments that fear similar action.

OUTLOOK: WHAT TO WATCH

• The ICJ judgment. Expected between November 2026 and January 2027. Venezuela's response, rhetorical or practical, will be the main test of the dispute.
• Border incidents. Armed gangs and illegal miners operate on both sides of the Cuyuní and in the Essequibo interior. Incidents involving Guyanese soldiers have occurred before and could be used politically after the ruling.
• Venezuela's transition. Whether the US-backed talks produce an election date, and whether Machado and the mainstream opposition are included, will decide the government's legitimacy.
• Maduro's trial. Proceedings in New York will keep the legality of the intervention in the news.
• Oil. Rising Venezuelan and Guyanese output increases the value of offshore areas near the disputed coast and the incentive for both governments to avoid conflict.

With Maduro gone and US influence over Caracas at its highest in decades, the danger of a Venezuelan military adventure in the Essequibo is lower than at any time since 2023. The claim itself remains, and the ICJ ruling will show whether Venezuela's new leaders treat it as a matter of law or of national politics.

FREQUENTLY ASKED QUESTIONS

What is the Essequibo dispute?

Venezuela claims the Essequibo region, about 160,000 km² or two-thirds of Guyana's territory, arguing that the 1899 arbitral award that set the border was invalid. Guyana says the award is final and asked the International Court of Justice in 2018 to confirm it.

When will the ICJ rule on Guyana v. Venezuela?

Oral hearings ended on 11 May 2026. Guyana's attorney general expects a final, binding judgment by or before January 2027, and the court has usually ruled six to eight months after hearings.

What happened to Nicolás Maduro?

US forces captured Maduro and his wife, Cilia Flores, in Caracas on 3 January 2026 and took them to New York, where they face drug-trafficking and narco-terrorism charges. Maduro denies the charges.

Who governs Venezuela now?

Delcy Rodríguez, Maduro's former vice-president, has been acting president since January 2026. The US recognised her authority in March. She has promised elections but has not set a date.

Will Venezuela accept the ICJ ruling on Essequibo?

Venezuela says no. At the hearings in May 2026 Rodríguez said no judgment would provide a solution acceptable to both parties, and Caracas continues to argue that the 1966 Geneva Agreement requires negotiation. It nevertheless took part in the proceedings.

Could Venezuela invade Guyana?

The risk is lower than in 2023–2024. Venezuela's acting government depends on US recognition and oil arrangements, and the United States is Guyana's main security partner. Border incidents and hostile rhetoric after the ruling remain possible.

How much oil does Guyana produce?

Guyana produced about 911,000 barrels a day on average in the first four months of 2026, all from the ExxonMobil-operated Stabroek block. Capacity is expected to exceed 1 million barrels a day when the Uaru project starts in late 2026.

Why did the US strike boats off Venezuela?

From September 2025 the US carried out more than 35 strikes on vessels it said were smuggling drugs, killing at least 115 people. The Trump administration described the campaign as part of an "armed conflict" with drug cartels. Critics have questioned its legality.
