The nation's fiscal problems are escalating rapidly as it undertakes what amounts to a form of nationalization.
A great deal of hard currency now goes to support domestic importers (that are forced to sell at a loss to keep prices under control) and the country is becoming desperate for dollars needed to import the products the population needs.

With fiscal deficit growing rapidly and access to international markets shut off due to the recent default, Argentina's central bank has been doing the only thing a central bank can do in this situation - monetize the deficit by printing more pesos. This has resulted in inflation levels of over 36% this summer and probably even higher currently. Not quite Zimbabwe levels yet, but moving in that direction.

One US dollar now trades at over 15 pesos in the unofficial ("blue") exchange market - some 80% premium to the official exchange rate.
