  • OPEC is targeting oil inventories, cutting production in an attempt to reduce the oil glut of the last couple years.
  • The surplus is declining, but it remains to be seen if that decline will continue.

"We will not let go of our current approach until we reach a balanced market," Saudi oil minister Khalid al-Falih said Monday at a news conference in Riyadh.


There isn't one at the moment, and we can assume OPEC doesn't know what comes next. But we do know that the group has one key metric in mind: inventories. The target is to bring global oil inventories back down to the five-year average.


It has been a stubborn thing, getting those inventories back down to average levels. A wave of shale bankruptcies didn't do it, the vanishing rig count didn't do it either. That led OPEC and a handful of non-OPEC countries led by Russia to limit their production. But even that deal didn't seem to be doing the trick at the start of 2017, as inventories remained stuck at elevated levels. The euphoria that followed the announcement of the initial deal gave way to a renewed sense of gloom, which pushed WTI back down into the low-$40s by mid-2017.

However, by the end of summer, the inventories finally started to move. And the declines accelerated in recent months, draining stocks at a rapid clip. Total crude and refined product inventories in OECD countries (the most visible and transparent metric used) has dropped to only 140 million barrels above the five-year average as of October, cutting the surplus from the start of 2017 by more than half.

The big question is when that surplus shrinks to zero. Saudi oil minister Khalid al-Falih warned that winter months tend to bring a dip in demand, which could meant the drawdowns slow for the rest of this year and in the first quarter of 2018. As such, the real progress won't begin until probably the second quarter.

Aiding in OPEC's effort is that the definition of "average" is constantly changing. With each passing day, the previous five years is increasingly made up of periods of time in which the oil market was in a glut. So, the "average" level for oil inventories today is a lot higher than it was three years ago. That means OPEC could achieve its objective with a lot more ease than if the target level was a fixed figure.

Demand is growing strongly, which will help soak up excess barrels as we head into next year. The supply picture is mixed, however. There is rising production in the U.S., Canada, Brazil and some other non-OPEC countries. On the other hand, OPEC countries will keep their output in check, and the inclusion of Nigeria and Libya under the cap will keep supply off the market. And Venezuela's production will continue to fall.

Although estimates vary, the IEA sees the supply surplus returning—in the first quarter of 2018, the energy agency sees a glut of 0.6 mb/d. In other words, inventories could swell for a period of time, although OPEC is not as pessimistic. But both agree that by mid-year, the drawdowns will really pick up pace, and the objective of "balancing" the market will draw near.

That makes the review period for OPEC's production limits in June very important. At that point, OPEC and non-OPEC countries will have to come up with an exit strategy. "The outlook for when we will hit the balanced market will be clearer in June, and we will start thinking of what we will do in 2019," al-Falih told reporters on Monday. "The intent is not overnight to open the taps and flood the market."
