Ah yes, the notoriously stable monetary union that was nearly taken down by Greece. South America does not have a Germany to bail out its many Greeces (in terms of fiscal prudence). No way this fails disastrously

eh- nearly taken down by greece but not.  also, they probably learned from it.  and lastly, it is only starting now for trade with each other.  

currently, it is brazilian real --&gt; dollar --&gt; peso, and when going from argentina it is peso --&gt; dollar --&gt; real.

they're going to use some sort of Special Purpose Investment Coin for all their trades, so it doesnt go into and out of USD.
