That's good. You're definitely the right person to answer my question. We know the concerns of the currency traders, in particular, with regard to the enormous U.S. deficit and the increasingly large U.S. loans made in foreign markets to finance their deficit. We've seen the price of crude oil, which was $19.71 in January 2002, rise to $98 in 2007. We also see the demand for the natural resources of emerging countries such as China and many others. All that has fostered the increase in the value of the dollar.
Do you think this is a trend? Or are these rather circumstantial events that we've seen for some time and that will not reoccur? Should we instead expect the dollar to remain high and to experience cyclical and very rapid fluctuations, as we've seen?
