Why do YOU think the U.S. dollar has declined against every other major currency in the last few years?
It's not because... (and they'd give me credit for the $3,500 difference)
A European investor paying 6500 Euros for a $10,000 bond that has a 4% coupon still earns 4%. I hope that's a little clearer.
As far as currency fluctuations, if I knew that, I'd be worth $1 billion, at least.
Lower demand.
