Top oil producers that are cooperating with the Organization of the Petroleum Exporting Countries (OPEC) on output cuts are pressuring OPEC, but OPEC needs to come up with the “right” call to safeguard the global economy which is “very fragile,” International Energy Agency (IEA) Executive Director Fatih Birol said on Tuesday. The Turkish energy expert also stressed that because of expected lower production growth in the United States as a result of financial troubles facing shale producers in North America, “there will be lots of oil in the market.” January futures of West Texas Intermediate (WTI) crude oi rose 0.40% to $58.05 per barrel at 5:36 am ET while Brent due in the first month of 2020 gained 0.22% to go for $63.61 per barrel at 5:37 am ET.
