Oil inches up on supply concerns and weaker dollar
SINGAPORE (Reuters) -Oil prices ticked up on Tuesday on concerns about supply, with Iran set to reject a U.S. nuclear deal proposal that would be key to easing sanctions on the major oil producer, while weakness in the dollar also supported prices. Brent crude futures gained 12 cents, or 0.19%, to $64.75 a barrel by 0627 GMT. The oil market surged higher on Monday as rising geopolitical risks and a supply hike from OPEC+ that fell short of expectations provided a boost, said ING analysts in a note.
