Currency value question
I was hoping to ask a bsaic question that occured to me recently. In addition to increased global demand driving up the price of oil, it occured to me that the value of the dollar is comparitively "weak" against other currencies. I'd presume that the dollar's buying power being relatively reduced would make foreiegn imports including imported oil cost more dollars. So my question being in basic terns what is causing the dollar to be relatively weak recently and is this a significant factor in oil being so costly of late? Wouldn't this alos have a strong inflationary influence on an eceonmy that imports more than it exports as I understand we do?
