I'm not an expert in this area, but I doubt the world changing their debt to a different currency is that simplistic... and I doubt you're an expert either. For one thing everyone wanting to get rid of their USD and buying EUR would cause the USD to crash and EUR to spike, so, well, there's their economic crisis (because suddenly your 10000 USD debt would turn from a ca. 8200 EUR debt to something like a 20000 EUR one).
