Appeals Court Voids $16.1 Billion Argentina Judgment

On March 27, 2026, a divided panel of the Second U.S. Circuit Court of Appeals in Manhattan struck down what had been the largest judgment ever awarded against a sovereign nation: $16.1 billion in damages against the Republic of Argentina for its 2012 seizure of oil giant YPF [1]. The 2-1 ruling wiped out claims by two former minority shareholders, sent the stock of litigation funder Burford Capital into freefall, and raised fundamental questions about whether U.S. courts are the right venue for disputes over sovereign expropriations.

The decision is a major win for Argentine President Javier Milei, who has spent his tenure trying to stabilize an economy battered by decades of fiscal crises. It is a devastating loss for Burford Capital, the London-listed litigation finance firm that funded the case and stood to collect much of the award [2].

The Seizure: How Argentina Took Back YPF

YPF, Argentina's largest oil and gas producer, was founded as a state enterprise in the early twentieth century, privatized in 1993, and eventually acquired by Spain's Repsol [3]. By the late 2000s, Repsol held a controlling 57.4% stake. The Petersen Group, controlled by the Argentine Eskenazi family, acquired approximately 25% through leveraged transactions in 2008 and 2011—financed by $1.685 billion from Repsol and $1.688 billion from international banks, with repayment to come from future YPF dividends [4]. Eton Park Capital Management, a New York-based hedge fund, held roughly 3%, making it the third-largest shareholder [4].

In April 2012, President Cristina Fernández de Kirchner moved to renationalize YPF, arguing that Repsol had underinvested in exploration and production, leaving Argentina short of oil and gas [3]. Argentina's Senate approved the takeover on April 26, 2012, with 63 votes in favor, three against, and four abstentions. The Chamber of Deputies followed on May 4, and Kirchner signed the expropriation law on May 5, seizing 51% of YPF's shares from Repsol [3].

Repsol initially demanded $10.5 billion in compensation [5]. After protracted negotiations, the two sides settled in February 2014 for $5 billion in Argentine government bonds, and Repsol withdrew all claims, including a pending arbitration at ICSID, the World Bank's dispute settlement body [5].

The Shareholders Left Behind

But Repsol's settlement covered only Repsol. The Petersen companies and Eton Park received nothing. Their argument was straightforward: YPF's corporate bylaws required any shareholder crossing the 49% ownership threshold to make a mandatory tender offer—an obligation to purchase shares from remaining shareholders at a fair price. When Argentina's stake exceeded that threshold through the expropriation, it triggered this obligation and then failed to honor it [6].

The Petersen plaintiffs and Eton Park sued in U.S. federal court in 2015. They could do so because YPF was listed on the New York Stock Exchange, giving U.S. courts a jurisdictional hook under the Foreign Sovereign Immunities Act's "commercial activity" exception [6]. The district court distinguished between Argentina's sovereign act of expropriation—which it treated as permissible—and the commercial obligation embedded in YPF's bylaws, which it said Argentina could not avoid simply by invoking sovereignty [6].

In March 2023, U.S. District Judge Loretta Preska ruled Argentina liable. In September 2023, she awarded damages: $14.4 billion to the Petersen entities and $1.7 billion to Eton Park, for a combined $16.1 billion [1]. Much of the total consisted of prejudgment interest accumulated over the eleven years since the expropriation [7]. By the time oral arguments took place on appeal in October 2025, interest had pushed the total past $18 billion [1].

The Valuation Fight

The $16.1 billion figure was built on the premise that Argentina owed minority shareholders the tender offer price they would have received had Argentina complied with YPF's bylaws. Argentina countered that this methodology vastly overstated YPF's worth at the time of seizure and that the plaintiffs' own acquisition costs were far lower—the Eskenazis had acquired their 25% stake entirely through debt, without putting up cash [4]. Argentina also argued that its expropriation law established a separate compensation framework that precluded private breach-of-contract claims [8].

The gap between the $5 billion Repsol accepted and the $16.1 billion awarded to minority shareholders holding a combined 25.4% stake underscored just how contested the valuation remained.

The Appeals Court Reversal

Writing for the 2-1 majority, Circuit Judge Denny Chin held that the plaintiffs' breach-of-contract claims "failed as a matter of Argentine law" [1]. The core reasoning: when a state exercises sovereign expropriation powers, those actions fall under public law, which takes precedence over private corporate bylaws [8]. Argentina's expropriation statute, Chin wrote, was "likely intended to mitigate the fallout" from exactly this kind of third-party litigation [1].

The majority acknowledged what it called "the Republic's knowing and flagrant violation of the promises it made to foreign investors" [9]. But it concluded that Argentine law did not permit shareholders to enforce the tender offer commitment through a breach-of-contract action in the circumstances created by a sovereign taking.

During oral arguments, the appellate judges had openly questioned why the case was being heard in a U.S. courtroom at all, given that the dispute centered on actions taken in Argentina and governed by Argentine law [8]. The U.S. Department of Justice had also weighed in on Argentina's side, arguing that the lower court's assertion of jurisdiction risked disrupting sovereign relations [10].

Circuit Judge José Cabranes dissented, arguing that the appeals court owed "special consideration and respect" to Judge Preska's findings, given her decade-long stewardship of the case [1].

The Burford Capital Fallout

No entity was hit harder by the ruling than Burford Capital, the publicly traded litigation finance company that funded much of the case. Burford's business model involves providing capital to plaintiffs in exchange for a share of eventual recoveries. The YPF case was the crown jewel of its portfolio—by some analyst estimates, it represented nearly half of the firm's perceived net asset value [2].

On March 27, Burford shares cratered 47% in U.S. trading, closing at $4.14 [1]. Multiple trading halts were triggered during the session [2]. CEO Christopher Bogart called the decision "obviously very disappointing" but said the core business "continues to perform strongly" [9].

The collapse reverberated across the litigation finance industry. Competitors like Omni Bridgeway face increased difficulty raising capital as the ruling exposed the concentration risk inherent in mega-case funding strategies [2]. Industry analysts expect a shift from the "Burford Model"—betting on transformative single wins—toward more diversified, portfolio-based approaches [2].

What Comes Next for the Plaintiffs

The plaintiffs have several options, though none are guaranteed:

Rehearing en banc: The plaintiffs have 14 days to petition the full Second Circuit to rehear the case. Statistically, en banc rehearings are rarely granted [9].

Supreme Court: If rehearing is denied, the plaintiffs have 90 days to file a petition for certiorari with the U.S. Supreme Court. Based on projected timelines, a cert petition could be filed by late September 2026, with a Supreme Court conference decision possible by December 2026. If cert is granted, oral arguments and a decision would follow by June 2027 [9]. The historical success rate for cert petitions in sovereign debt cases is low, though the magnitude and novelty of this case could attract the Court's interest.

Investment treaty arbitration: Burford has indicated that it is pursuing arbitration against Argentina under bilateral investment treaties, with King & Spalding leading the effort [9]. This route bypasses U.S. courts entirely and could take years.

How This Compares to Other Sovereign Debt Battles

The $16.1 billion judgment dwarfed every prior award against a sovereign nation. For context, Elliott Management's 15-year campaign against Argentina over its 2001 default—often called the "sovereign debt trial of the century"—resulted in judgments of approximately $1.6 billion against Argentina's NML Capital subsidiary [11]. Elliott eventually collected when Argentina settled with holdout creditors in 2016 for $4.65 billion in cash, roughly 75 cents on the dollar of principal and interest [12]. Elliott's profit on the trade exceeded $2 billion [11].

Other notable sovereign judgments include Elliott's $58 million award against Peru in 1998 and a British court's award of over $100 million against the Republic of Congo in the early 2000s [11]. None approached the scale of the YPF case.

The critical difference: Elliott's Argentina claims were based on sovereign bonds with New York-law governing clauses, giving U.S. courts clear jurisdiction. The YPF case, by contrast, turned on corporate bylaws and Argentine expropriation law—a much more contested jurisdictional basis.

Argentina's Fiscal Position

The ruling removes what would have been a staggering financial burden. Argentina's GDP stood at approximately $638 billion in 2024 [13]. A $16.1 billion judgment would have represented roughly 2.5% of GDP—or, as President Milei noted, nearly 45% of annual government expenditures [2].

Data as of Mar 28, 2026CSV

Argentina's public debt stood at approximately $467 billion at the end of 2024, or 83.2% of GDP [14]. The country's gross foreign reserves reached $46.24 billion in early 2026, the highest since 2021 [15]. A $16.1 billion payout would have consumed more than a third of those reserves.

Under Milei, Argentina has achieved a primary fiscal surplus of 1.6% of GDP and has been rebuilding reserves, with a target of $10–17 billion in central bank dollar purchases for 2026 [14][15]. S&P rates Argentina CCC+ with a stable outlook; Fitch has said further upgrades depend on continued reserve accumulation [15].

The elimination of the $16.1 billion contingent liability should modestly improve Argentina's credit profile. YPF shares rose more than 6% following the ruling, and Argentine sovereign bonds saw modest gains [2].

Broader Implications for Sovereign Litigation

The ruling arrives at an inflection point for sovereign debt law. Several effects are already visible:

U.S. courts as a venue: The Second Circuit's skepticism about adjudicating sovereign policy decisions in American courtrooms signals increased judicial restraint. This coincides with the proposed "Protecting Our Courts from Foreign Manipulation Act of 2025," which seeks to limit foreign-funded entities' ability to use U.S. courts for sovereign disputes [2].

Litigation finance: The industry faces a reckoning. If appellate courts are willing to overturn multi-billion-dollar sovereign judgments on substantive legal grounds, the risk-reward calculus for funding such cases shifts dramatically. Burford's collapse illustrates the binary nature of these bets [2].

Signal to other sovereigns: Countries facing bondholder disputes—including Venezuela, which defaulted on approximately $60 billion in sovereign and PDVSA bonds, and Lebanon, which defaulted in 2020—may take comfort from the ruling. It suggests that sovereign expropriations, even those that breach private contracts, may be insulated from enforcement in U.S. courts when domestic public law provides an alternative compensation framework [8].

Argentina's market re-entry: Argentina has signaled plans to return to international debt markets for the first time in eight years [15]. The removal of the YPF liability clears a significant obstacle. Whether investors view the ruling as evidence of improved rule-of-law credibility or as confirmation that Argentina can expropriate without full consequences will shape the terms of any new issuance.

The Political Dimension

Milei celebrated the ruling as vindication, declaring: "Today is a day of celebration for the good Argentines. What seemed impossible, we made possible" [16]. He announced plans to send Congress legislation limiting expropriations and increasing compensation limits—a signal aimed at foreign investors that Argentina under his administration will not repeat the policies of the Kirchner era [16].

He also used the occasion to attack former President Kirchner, whose government carried out the nationalization. The political dynamics are significant: Milei's economic program depends on attracting foreign investment, particularly in the Vaca Muerta shale formation, where YPF—now reporting $5 billion in annual profit—is the dominant operator [16].

Unanswered Questions

Several uncertainties remain. The en banc petition and potential Supreme Court review could take more than a year to resolve. Investment treaty arbitration, if pursued, would unfold over an even longer timeline and in a different legal framework.

The case also leaves unresolved the broader question of how courts should handle sovereign takings that intersect with private commercial obligations. Judge Chin's ruling establishes that Argentine public law displaces private contract claims in the expropriation context, but this reasoning may not translate cleanly to other jurisdictions or legal systems.

For the thousands of retail investors who held YPF shares through Petersen's corporate structure, and for Burford Capital's shareholders who watched nearly half their company's perceived value evaporate in a single trading session, the legal questions are academic. The money—$16.1 billion of it—is gone, at least for now.
