In the global crude oil market, at least some degree of coordinated management of supply has been the norm since the end of World War II. From the mid-1940s to the early 1970s, the cabal of oil companies known as the Seven Sisters jointly managed production to keep crude prices at levels that accommodated their interests. Then it was OPEC’s turn. More recently, the efforts to keep supply from overwhelming demand — and help prevent oil prices from crashing — have been led by a combination of OPEC and some other major producers, including Russia. U.S. shale producers — who’ve contributed significantly to the global supply growth in recent years — have both benefited from this supply management and partially thwarted it by continuing to increase production to offset cuts by “OPEC-Plus.” But a projected slowdown in U.S. production growth in 2021 may change these market dynamics. Today, we begin a short blog series on global oil supply and demand trends, supply management efforts by OPEC-Plus, and what it all means for OPEC, U.S. producers and the broader oil market.
