Argentina's Milei plans to strengthen sanctions against companies operating in Falklands

September 14, 2026

Analysts say that the Argentine president Javier Milei will be preparing legislation to strengthen sanctions against companies in the Falkland islands this week. This raises the question of whether he might escalate tensions between Argentina and Britain by targeting sectors other than the disputed islands’ economy.

The bill is based on the sanctions that Argentina's government has allegedly opened against 60 companies and individuals involved in offshore oil exploration near the islands. Argentina claims ownership of these islands which it calls "the Malvinas" even though Britain owns them. Argentina invaded and fought for 10 weeks over the islands before giving them up to Britain in 1982.

The budget proposal for 2027 from Milei is expected to be received by the Congress on Tuesday. The budget is expected to increase defense spending in order to better address sovereignty concerns.

Donald Trump, the U.S. president, suggested this month that Washington might reconsider its neutrality on the Falklands conflict. Argentina has intensified its efforts since then to target oil companies that are involved in drilling around the Falkland Islands.

Marcelo Seghini, a congressional aide to Milei, said that the proposed legislation would include tougher penalties against unauthorized operations in and around the islands. He said that the legislation would include'sanctions for affiliates, and other activities affecting Argentina’s natural resources.

This follows a criminal case filed last week by companies connected to the Sea Lion Offshore Project in the Falklands.

The government of Argentina has not replied to requests for comments?or provided any list of companies that are facing sanctions proceedings despite local media reporting names.

Analysts were unsure about the scope Milei's proposed bill on "national sovereignty defence" but called his sanctions a aggressive effort to translate Argentina's sovereignty claims in legal and commercial pressure.

Marcelo Elizondo said, "It wasn't a project that was developed over a long period of time or carefully prepared," the Argentina representative at the International Chamber of Commerce. He said that Trump's remarks "created an environment" which the government wanted to take advantage of quickly.

Investors and companies are evaluating if sanctions will affect firms operating in Argentina. This includes those who have a stake in Argentina's vast Vaca Muerta shale formation.

The reported sanctions have already caused some controversy. Dutch geodata specialist Fugro released a statement claiming that local media had incorrectly identified it as working with the Sea Lion Project. Fugro added that its activities were limited to a work on a submarine telecommunications cables.

BROAD SANCTIONS

Experts say the measures could hinder the development of the Sea Lion Project by creating a chilling affect on companies that work with owners Navitas Petroleum or Rockhopper Exploration.

Both companies said that the oilfield project has valid licenses issued by the Falkland Islands Government and they did not expect Milei to derail the development.

In a government document, a number of financial intermediaries and shareholders were listed as companies that could face sanctions. Vanguard, First Eagle and Canaccord were among the companies that could face sanctions. Interactive Investor, owned by Aberdeen, was also included.

SLB, Baker Hughes, and Halliburton are among the oil majors that have announced in recent days they will not be participating in any activities on the island.

"Without major service companies, one would have to turn to mid-sized firms with less established technical capabilities--companies that might be more expensive or slower to mobilize," Juan Jose Carbajales, a former undersecretary of hydrocarbons in the former center-left government of President Alberto Fernandez.

Seghini told the Milei government that the expected legislation would include sanctions for the fishing industry. This could target a sector which is a major part of the Falkland Islands' economy.

Federico Merke is a political science professor at the University of San Andres, Buenos Aires. He said that the more you widen your supply chain, you risk being hit with sanctions.

OPPOSITIONAL PRESSURE

Milei's libertarian coalition, which lacks majority support in Congress, has struggled to gain support for economic reforms.

Left-wing and center-right opponents have accused Milei for years of not doing enough in defending Argentina's claim to the Malvinas. They now say that he is acting out of political motives ahead of his likely reelection campaign in 2027.

Aldo Leiva said that he was clearly using the Malvinas as a political tool. "If he wanted the defend the sovereignty of Malvinas during these two years of government, then he had all the tools needed to do so."

Marcelo 'Garcia, a Buenos Aires-based analyst with Horizon Engage, says that Milei’s legislation is unsettling to investors because it could force the opposition to escalate its measures against the United Kingdom.

Garcia said: "There were already concerns about the elections in Argentina next year. What if there is a populist reaction?"

Former secretary of international relations for the Defense Ministry, Francisco Cafiero said that the incident reflected a lack of clarity in strategy.

He said, "We navigate in an environment of uncertainty and improvisation."
