A U.S. federal judge, Loretta Preska, ordered Argentina to transfer its controlling 51% stake in the state-run oil and gas company YPF to satisfy part of a $16.1 billion court judgment. The ruling stems from a long-running legal dispute over the 2012 expropriation of YPF, which had been majority-owned by Spanish company Repsol before nationalization under former Argentine administrations. Argentina was initially given 14 days to comply but sought extensions and appealed the decision, arguing that enforcement would violate U.S. and international law. Judge Preska rejected Argentina's appeals and accused the country of delaying tactics. However, the U.S. Court of Appeals for the Second Circuit in New York temporarily suspended the order to transfer shares, granting Argentina additional time to seek a longer delay. The U.S. government, under the Trump administration, filed an amicus curiae brief supporting Argentina's position in the appeals process. The plaintiffs in the case include hedge funds Burford Capital and Eton Capital, which are seeking to collect the judgment. Argentine President Javier Milei confirmed the government will continue to appeal the ruling and stated that Argentina will not negotiate any settlement with Burford Capital. The legal conflict has created uncertainty over Argentina's control of YPF, one of its principal energy companies, and has led to market losses for Argentine assets.
