From the Buenos Aires Herald, the city's "English" language newspaper:

Banks continued to ease the restrictions on frozen bank deposits yesterday but the process was marked by a series of glitches. The Central Bank ruled late Tuesday that as of yesterday depositors could swap up to 5,000 dollars in their accounts into pesos at the official exchange rate of 1.40 pesos to the dollar. However numerous banks were unable to pesify the deposits, alleging that the Central Bank had issued the ruling too late the night before for them to modify their systems.

Pesify - to exchange dollars for pesos.

Any other currency-based verbs? I'll add that the current crisis in Argentina was intensified by the Government's decision to "de-dollarize" their currency. The value of the peso had been pegged to that of the dollar (dollarized) since the early '90s.
