It will most likely be like a market crash. Several countries are grimly hanging on to their US long bonds eyeing each other off right now, like in "The good, the bad and the ugly". Once someone draws their gun and starts selling hard it will set off the panic. Then they will all shoot each other simultaneously and the $US loses half it's value, gold doubles. imo.
Can I ask those who think the govts can support the $US, who the buyers will be? Take a less extreme example of 1992 when the UK govt tried to hold it's currency up - the speculators won and the pound lost 30% in a day, and taxpayers lost billions in failed support.
