Argentina seeks UK funds for expropriated oil group YPF The YPF executives will meet with oil producers Exxon Mobil and Apache in Houston as part of the roadshow, which will also take in Los Angeles, Boston and New York, Bloomberg reported. Argentina approved the expropriation of YPF, the country's biggest oil company, from Spanish energy giant Repsol in May, with the latter's executive chairman, Antonio Brufau, insisting the move was an "illegal act" that would "not remain unpunished." Repsol has since vowed to fight for $10bn compensation. Separately, YPF shareholders has approved increasing a programme to issue debt to as much as $3bn from $1bn, the company said.
