The Blue dollar refers to the grey market exchange rate currently hovering around 950 Argentina Pesos to 1 US Dollar. The official exchange rate is set at about 350 to 1. It is actually quite hard to spend US dollars directly in Arg. However it is common for both foreigners and Argentines to use grey market money changers at the blue rate. Argentines are only allowed to purchase a limited number of US dollars at the official rate each month so if they want to travel or protect the value of their savings from the extreme inflation they need to use the grey market to do so. The Blue dollar exist because the current government artificially pegs the peso at the lower rate.
