Oil prices reached their highest so far for 2019 on Thursday as global markets tightened amid supply cuts led by producer club OPEC and U.S. government sanctions against Iran and Venezuela.
International Brent crude oil futures hit a November 2018 high of $68.64 per barrel around at 0453 GMT on Thursday, up 14 cents, or 0.2 percent from their last close.
U.S. West Texas Intermediate (WTI) crude futures also equalled a November 2018 high of $60.27 per barrel on Thursday.
Crude prices have been pushed up by almost a third since the start of 2019 by supply cuts led by the Organization of the Petroleum Exporting Countries (OPEC), as well as by sanctions enacted against Iran and Venezuela by the United States.
