Investing.com - IEA chief Fatih Birol sees OPEC output cut speeding up oil market rebalancing.
Prior to OPEC deal, the International Energy Agency expected a balance between demand and supply toward end-2017.
The key issue is compliance with the agreed cut in OPEC output of 1.2 mn b/d at start of next year.
"If it implemented we may well see it (rebalancing) happen significantly earlier," Birol told Reuters.
OPEC is due to meet with non-OPEC producers this weekend to discuss proposed 600,000 b/d by the latter.
U.S. crude fell 0.66% at $51.45 at 06:15 ET Tuesday as OPEC output rose in November.
