Argentina lifts restrictions on buying foreign currency Argentina on Friday lifted restrictions in place since 2011 that limited the purchase of foreign currency, a day after the peso suffered its worst single-day dive since the 2002 financial crisis. But this latest measure does not impact a lot of Argentines as the vast majority only have access to pesos. According to the government, between 3% and 5% of the Argentine population is concerned when talking about foreign currency exchange. Images and soundbites.
