...some people objected to my claim that the IMF encouraged them to peg their currency. That appears to be a correct criticism, though from what I can find out at the moment the currency peg was enacted without IMF protest in the midst of a lot of other neo-liberal reforms which were IMF-encouraged.. The real failure of the IMF was their continued insistence that the peg be maintained, and their foisting of various loans for this purpose onto them. It's important to realize that a lot of the money loaned was simply used to maintain the currency peg. Dollars were loaned to the central bank, which were then simply spent buying pesos that were being traded in for dollars as people awaited the inevitable devaluation/float.
