Most of it is flight-to-quality if I had to guess. But that means that the greenback is still trusted above all, doesn't it? I've no doubt the dollar will eventually resume it's downtrend. But at the end of the day, we're all here to trade, and these movements make our days, right? Incidently, whoever added their vote to the "Dollar has bottomed" vote just now- you suck, you're too late.
