> Separately this is generally not a great idea economically. You do kill inflation in Argentina (replaced with American inflation but that is extremely low and stable by Argentine standards). But you have no control over your monetary policy or your exchange rates. If your economy is export driven to (e.g.) China, you now have to worry about the dollar-yuan rate, which is not under your control. I am not a economics person by any sort, but why does that matter? If China is buying say minerals at $4 a ton or something, versus 1415.41 Pesos how does that change. If US is strong and the Yuan dips, it now costs X% more to convert to $ then before, that just means you decrease price of export by X %? If we are speaking entirely on a 1 to 1 partner. But on the plus side it also opens you up to buyers who trade in USD, they no longer need to trade to a bunch of Peso first. And since most export companies probably already accept USD for trades, I don't see what the negative is.
