A St. Louis Fed note asks whether OPEC still controls oil prices, noting OPEC holds 42 percent of world output while prices barely reacted to the September and November 2016 cut announcements. It cites rising non-OPEC output, which grew 3.1 percent in 2015.
A weaker OPEC price effect means cuts may deliver less price support than markets expect, keeping crude and energy-linked costs more exposed to supply growth.
