Oil prices rose by more than 1 percent on Tuesday as the dollar slipped to an 18-month low against the yen, potentially spurring fuel demand, although gains were restricted by rising Middle East output that renewed concerns of a global supply overhang.
Brent crude futures were trading at $46.29 per barrel at 07-29 GMT, up around half a dollar or 1 percent from their last close. U.S. crude futureswere also up almost half a dollar and more than 1 percent at $45.25 a barrel.
