Overview
- President Javier Milei used a nationwide cadena nacional on Thursday to relaunch the Malvinas sovereignty claim and the government published decrees 867/2026 and 868/2026 on Friday to reassign budgets and set new controls for hydrocarbon activity.
- Officials say the push followed an SIDE intelligence assessment of companies operating around the islands and public comments by President Trump that the government viewed as a diplomatic opening for action.
- Casa Rosada announced sanction procedures that have notified about 45 firms and compiled a list of roughly 70 companies tied to Sea Lion, and the administration plans to draft a bill to expand penalties to company directors and to cover all natural‑resource activities.
- Major oil‑services firms — SLB, Halliburton and Baker Hughes — publicly declined to work in the Malvinas zone, while Sea Lion operators Navitas and Rockhopper say they will keep to their drilling and production timetable.
- The measures have split domestic politics, drawn industry backlash over potential lost contracts, and set up near‑term flashpoints including congressional debate on the proposed law, formal firm notifications, possible legal challenges, and statements from the UK and the United States.
