On the morning of March 27, 2026, a federal appeals court in New York handed Argentina one of the most consequential legal victories in its modern history. With a 2-1 vote, the Second Circuit Court of Appeals reversed a massive judgment that had threatened to saddle the country with a bill of roughly $16 to $18 billion — a sum comparable to the entire IMF loan Argentina received in 2024.

The short answer: A US appeals court threw out a multibillion-dollar ruling against Argentina in the YPF oil company case, saving the country from a potentially catastrophic payout. The ruling validated a legal argument Argentina's governments have consistently made for over a decade — but a fierce political fight over who deserves the credit has already broken out between President Javier Milei and the opposition.

What Was the YPF Lawsuit and Why Did It Threaten Argentina?

YPF is Argentina's national oil company, the crown jewel of its energy sector and a key driver of the Vaca Muerta shale fields in Patagonia — one of the world's largest untapped hydrocarbon reserves. Founded in 1922, YPF was privatized in the 1990s before being renationalized in 2012, during the second presidency of Cristina Fernández de Kirchner, when the government expropriated a 51% stake from the Spanish energy company Repsol.

That move angered minority shareholders, particularly a group of investors who claimed Argentina violated the terms of YPF's own corporate statutes. Those statutes, dating from the privatization era of the 1990s, required that any party acquiring a controlling stake must make a public buyout offer to all remaining shareholders. Argentina never made that offer. Minority investors sued.

The case ended up in New York, where in late 2023 Judge Loretta Preska ruled against Argentina and ordered it to pay roughly $16 billion in damages — one of the largest foreign sovereign debt judgments in US legal history. The firm that had purchased the litigation rights and stood to collect the bulk of that award was Burford Capital, a British litigation finance company.

What Did the Appeals Court Actually Decide?

The Second Circuit Court of Appeals reviewed the case and, by a 2-1 margin, concluded that Judge Preska had fundamentally misapplied Argentine law. The majority found that Argentina's General Expropriation Law — a sovereign legislative act — governs the entire process of nationalization and any consequences flowing from it. Because the expropriation was an act of public law, shareholders seeking compensation had to pursue remedies through Argentine courts under Argentine law, not through the YPF corporate statutes in a New York courtroom.

In plain terms: the appeals court said the Argentine government acted within its sovereign rights, and that those rights supersede the fine print in a private corporate charter.

The dissenting judge, José Cabranes, disagreed, arguing that Argentina had made a contractual commitment to shareholders when it privatized YPF in the 1990s, and that the expropriation couldn't simply erase that promise. His view was that minority investors were left without an effective remedy — a precedent he warned could unsettle investor confidence.

The ruling ordered the dismissal of all remaining claims. Burford Capital's share price fell more than 40% on the day of the announcement. YPF stock, meanwhile, climbed to historic highs.

This is where the story gets politically charged — and where the facts are clear.

The legal strategy Argentina deployed was not invented by Milei. Multiple experts and legal analysts confirmed in the hours after the ruling that the core argument — that Argentine sovereign law takes precedence over YPF's corporate statutes — has been Argentina's consistent position since the very beginning of the case, spanning the governments of Cristina Fernández de Kirchner, Mauricio Macri, Alberto Fernández, and now Javier Milei. The law firm defending Argentina in front of the Second Circuit is the same one appointed under the Alberto Fernández administration.

There were no sudden strategic pivots, no novel legal theories introduced under Milei. As legal analyst Sebastián Maril put it in a live broadcast: "The legal strategy has always been the same. Every government that came in changed almost everything — except the legal approach in this case."

Milei did make one real contribution: his government refused to negotiate a settlement. According to Economy Minister Luis Caputo, multiple lobbyists — including well-connected Wall Street figures hired by Burford — arrived at the government's door seeking a deal. The government turned them all away. That decision to run out the clock and let the appeal play out was a genuine strategic choice, one that happened to be vindicated by Thursday's ruling.

Is Milei Right to Claim This as His Own Victory?

The question of credit will fuel Argentine politics for months. When the ruling landed, Milei appeared at a public event and immediately framed it as a rescue mission: "We had to come and fix the mess made by that useless, incompetent Kicillof during the second government of the corrupt Cristina Kirchner," he declared, referring to Axel Kicillof, who served as Economy Minister when the nationalization was carried out and is now Governor of Buenos Aires Province.

Milei's office published a statement saying his government had "faced this immense challenge with seriousness and concrete results," while previous administrations had "compromised public resources and damaged Argentina's international credibility."

Kicillof pushed back sharply. He called Milei's comments "sad, lamentable, and pathetic" and pointed out that the appeals court had, in effect, validated the same legal argument he had championed since 2012 — that the Argentine expropriation law stands above a private corporate charter. "The defense continued along exactly the same line we always maintained," he said. "Milei defended the vulture funds to attack me politically, and now he wants to take credit for a victory won with our arguments."

The truth, as reconstructed from the court record and confirmed by multiple legal observers, sits somewhere in between. The victory belongs to Argentina as an institution — to a decade-long legal position maintained across ideological lines — not to any single government. Milei wins points for not settling. Kicillof wins points for the original legal theory the court upheld. Neither side gets to claim exclusive ownership.

What Does This Mean for Burford Capital and Investors?

For Burford Capital — a firm that specializes in buying litigation rights and collecting judgments — this is a catastrophic outcome. The company had acquired the claims of the original minority shareholders and had seen its market capitalization soar after Preska's 2023 verdict. The reversal erases that gain and raises serious questions about the viability of sovereign litigation of this scale.

For Argentina's sovereign debt markets, the picture is more nuanced. Logically, removing an $18 billion contingent liability should be unambiguously good news for bondholders. In practice, markets on Thursday showed a slightly contradictory reaction — YPF shares surged while Argentine sovereign bonds dipped and the country risk index edged back above 600 points. Analysts suggested this may reflect the broader global context, including rising tensions over the Iran conflict pushing investors into defensive positions.

Still, the medium-term implications are positive. Argentina's debt profile just became measurably safer, and the government can point to a concrete legal victory as it heads into a presidential election in which Milei is seeking reelection.

Could Argentina's Victory Be Reversed?

Probably not, but it isn't entirely over. The parties who lost — Burford and the original shareholders — have two remaining options. They can request that the full Second Circuit bench review the panel's decision, a process called an en banc rehearing. Or they can petition the US Supreme Court. Legal experts put the chances of either path succeeding as very low: en banc reversals of a panel ruling are rare, and the Supreme Court takes fewer than 1% of cases it receives and generally avoids disputes that turn on the application of foreign law. As Maril assessed: "About 95% of what we hoped for in Argentina's favor happened today."

The ruling closes a legal chapter that hung over Argentina for more than a decade. It is unambiguously good news for the country. But the political fight over who gets to wear the victory is only just beginning — and with a presidential election approaching in which Milei is seeking a second term, neither side will let it go quietly.

Frequently Asked Questions

What is YPF and why is it so important to Argentina? YPF is Argentina's state-controlled oil company, founded in 1922 and privatized in the 1990s before being renationalized in 2012. It operates the Vaca Muerta formation, one of the world's largest shale reserves, which has become a central pillar of Argentina's energy production and export strategy.

Who is Burford Capital and why did its stock collapse? Burford Capital is a British litigation finance company that purchased the legal claims of minority YPF shareholders and stood to collect billions if Argentina lost. When the appeals court overturned the judgment, those claims were rendered worthless, wiping out more than 40% of Burford's market value in a single session.

Did Argentina's relationship with Trump help win the case? The question has been raised, but legal experts are skeptical. The majority opinion is a detailed legal document focused entirely on the proper application of Argentine expropriation law — there is no visible trace of political influence. Kicillof himself noted that if the ruling reflected the Milei-Trump relationship rather than legal merit, it would be a serious institutional scandal. The court's analysis points consistently to points of law, not to foreign policy.

Was Kicillof right to nationalize YPF in 2012? The appeals court's ruling vindicates the legal method of the nationalization — it was carried out in accordance with Argentine sovereign law. Whether the decision was economically wise remains debated. Critics argued that expropriating Repsol damaged Argentina's reputation with foreign investors at a critical moment. Supporters point out that YPF went on to develop Vaca Muerta into a world-class energy asset that now underpins Argentina's fiscal position. Both things can be true at once.
