  • Oil supplies from producers outside OPEC will grow by 1.5 million barrels a day in 2018, the International Energy Agency forecast.
  • Global demand for crude will jump by 1.4 million barrels a day next year, the IEA said.
  • The supply growth will largely be driven by surging U.S. production.

Oil output from the United States and other non-OPEC countries will grow more than global crude demand in 2018, driven largely by surging supplies from U.S. shale fields, according to a leading energy policy advisor.

The assessment is the latest sign that the crude market may struggle to work through a prolonged oil glut well into next year — and that American drillers will play a major role in the ongoing drama.
