I spent a few years in Belize, and their currency is pegged 2:1 to the USD. Given the size, capability, and general competency of the Belizean government I always felt it was a major catastrophe just waiting to happen. Worse, nobody there seems to be remotely aware that this is a very risky way to manage your currency. If it were to collapse it would be a terrible blow to an already struggling country. Like diaspora terrible.
