Argentina is ramping up pressure on energy companies involved in offshore oil development around the Falkland Islands (known as the Malvinas in Argentina) as the territory approaches its first oil production, reigniting a long-standing sovereignty dispute with the United Kingdom.
Over the weekend, President Javier Milei’s administration released statements from major oilfield service providers Halliburton, SLB, and Baker Hughes, all of whom confirmed they have no involvement in the offshore projects near the islands.
As the islands edge closer to their first offshore oil output, the economic stakes of the territorial dispute—which led to a war between Argentina and the UK in 1982—have heightened. In response, Argentine Foreign Minister Pablo Quirno has publicly criticized firms participating in the region’s emerging energy sector, and the government has tightened sanctions against companies operating there. Meanwhile, British officials have reaffirmed that the Falkland Islands remain under UK sovereignty.
The Argentine government’s campaign has also put local businessman Eduardo Elsztain under the spotlight. Elsztain’s Dolphin Fund Ltd. owns a 2% stake in FIH Group Plc, the parent company of the Falkland Islands Company. Following criticism over his financial links to the British territory, Elsztain defended the holding on Sunday, stating that the investment was meant to foster commercial and economic connections rather than compromise Argentina’s sovereignty claim.
In a LinkedIn post, Elsztain, who also serves as the CEO of real estate firm IRSA, shared a perspective passed down from his grandfather, suggesting that active Argentine economic involvement in the islands during the 20th century might have prevented the 1982 conflict. Elsztain had previously attempted to buy a majority stake in the Falkland Islands Company, but the transaction was blocked by British authorities who refused to let an Argentine investor gain control of the enterprise.
As offshore oil development progresses, the Milei administration continues to intensify its focus on the Falklands, placing any companies with real or perceived commercial ties to the islands under increased scrutiny.
