>Whoever is buying dollars (or dollar-denominated goods) at the "official" exchange rate is making a killing. And will do so for about 6-9 months, before the entire thing collapses.

It's been like that ever since the currency controls were implemented in 2003, it is fairly well known that most if not all of the high ranked government officials (who have unlimited access to preferencial exchange rates) are behind the currency "black" market. The same government officials have their fair share of cash stashed away in tax havens.

This is beyond hope, corruption is not only endemic anymore but a neccessity for survival, unfortunately this will only end with blood, I believe international interference is a must in this case.
