Global oil stocks which rose during the height of the pandemic are being steadily reduced, the International Energy Agency (IEA) said on Wednesday, but a second wave is slowing demand and will complicate efforts by producers to balance the market.

OPEC+ producers – OPEC members and others including Russia – plan to boost supply by 2 million barrels per day (bpd) from January and the IEA predicts a ceasefire in Libya will raise output there to 700,000 bpd in December from 300,000 bpd currently.

“There is only limited headroom for the market to absorb extra supply in the next few months,” the IEA said in its monthly report. “Those wishing to bring about a tighter oil market are looking at a moving target.”
