Argentina's Congress has nationalised the country's biggest oil company, YPF, by an overwhelming lower house vote that underscored broad popular support for a measure that threatens to scare off foreign investment.
The Chamber of Deputies voted 207-32 in favour of expropriating YPF, clearing the way for President Cristina Fernandez to sign the bill into law. The Senate last week approved the measure by a similarly overwhelming margin, Reuters reported.
Fernandez, who has tightened state control of the economy, unveiled the plan to seize a majority stake in YPF from Spain's Repsol six months after her landslide re-election.
The move drew a swift reprisal from Spain, which curtailed Argentine biodiesel shipments. Wall Street warns that Argentina risks scaring off investment needed to bolster growth against fallout from Europe's debt crisis and slower demand from key trade partner Brazil.
Business groups have long been put off by Fernandez's policies, such as her government's takeover of Argentina's private pension system in 2008 and, more recently, import and foreign exchange controls that have hurt confidence.
Fernandez justifies the renationalisation of YPF - which was privatised in the 1990s after decades as a state-owned company - on the grounds that it failed to boost oil and natural gas production needed to keep up with local demand.
Energy import bills have shot higher, putting Argentina's prized trade surplus at risk.
Repsol denies under-investing, but the government's message has struck a chord with Argentines, many of whom are suspicious of foreign companies and blame the free-market policies of the 1990s for setting the country up for its 2001/02 sovereign debt default and shock currency devaluation.
"All oil companies that operate in Argentina, Repsol and the rest, have to work in the public interest, which in this case means energy self sufficiency for Argentina," Agustin Rossi, leader of the official bloc in the lower house, shouted during a speech to the chamber just before the vote.
"Repsol invested little in Argentina," Rossi said. "But it was YPF and Argentine oil that financed Repsol's growth around the world."
