Ad, Chuckey, The US dollar didnt rise last year because of a rush to safety, it was more a rush to meet demands for debt repayments denominated in USD. Debtors had no choice. As I read Mish & Denninger, this looks to be on the cards again (no pun intended).
A cynic (like me) would suggest these crises are being manufactured to renew interest in USD & UST's just as the world appears ready to bail & collapse the stinking mess in on itself. What better way to keep the value of your stash of dollars buoyant (for a while) than threaten the world's debtors with destruction if they dont pay up?
