I wonder if anyone on this thread can give me an explanation of why the USDollar is so strong these last 8-10 weeks. I fail to understand what fundamentals have caused what would have to be one enormous flow of capital to the dollar to precipitate the change in value. There has not been a big change in the interest rates etc to explain it to me. But dollars are being bought big time and what I would like to know is why?

Look forward to some theories or explanations.
