BUENOS AIRES, May 2 (Reuters) - Spain's Repsol may halt the delivery of nine ships carrying LNG to Argentina in retaliation for the South American government's pending nationalization of its YPF unit, a source in the energy sector said on Wednesday.
The cancellation of the shipments, which is still being studied, could cause shortages in Argentina where the government relies heavily on imports because local gas and oil production has slumped on price controls that critics say discourage investment.
Repsol suspended the first of 10 planned LNG shipments several days ago, citing concerns that Argentina's state energy company Enarsa, which manages imports, might lack financial payment guarantees.
"The chance that all shipments will be cancelled is high. Repsol is studying whether to cancel these sales. It's a response to the nationalization of YPF," the source, who spoke on condition of anonymity, said.
