While Congress and a few analysts may believe crude oil would dip back to $50 per barrel if they restrict investment in commodity index funds, a more reliable predictor of the price of crude in recent months is the value of the dollar. When the dollar experienced a slight recovery due to some hawkish inflation talk from the Fed, crude oil dipped to just over $120; when the European Central Bank indicated that they may tighten rates, the dollar fell back and crude made new highs. But on Friday even though the dollar index made a three-month high, crude dropped by less than $2 and today with the dollar weakening, crude has set its all-time front-month high of $139.89.
