Energy markets, OPEC+ & the geopolitics of transition
Energy markets, OPEC+ supply management, oil-price shocks, and how the energy transition reshapes geopolitics, sanctions and strategic minerals.
The architecture of global oil
Crude oil remains the single most traded physical commodity, priced off two benchmarks: Brent (North Sea, the global marker for roughly two-thirds of traded crude) and West Texas Intermediate (WTI) (the US landlocked benchmark settled at Cushing, Oklahoma). Prices are discovered on the ICE and NYMEX futures exchanges and transmitted instantly into transport, fertiliser, plastics and food costs—which is why oil is a macro variable, not merely a sector.
The Organization of the Petroleum Exporting Countries (OPEC), founded in Baghdad in September 1960 by Iran, Iraq, Kuwait, Saudi Arabia and Venezuela, exists to coordinate output and stabilise prices. Its decisive moment was the 1973 oil embargo, when Arab members of OPEC, acting through OAPEC after the Yom Kippur War, quadrupled prices from roughly $3 to $12 a barrel, triggering stagflation across the OECD and the creation of the International Energy Agency (IEA) in 1974 as a consumer-side counterweight holding strategic petroleum reserves.
OPEC+ and the swing producer
Since December 2016, OPEC has acted with ten non-member exporters—above all Russia—as OPEC+, a bloc controlling close to 40% of world output and the bulk of spare capacity. Saudi Arabia is the swing producer: only it holds meaningful idle capacity to raise or cut output quickly. The arrangement nearly collapsed in March 2020 when a Saudi-Russian price war coincided with the COVID demand crash, briefly driving WTI futures negative (−$37/barrel on 20 April 2020). The cartel responded with a record ~9.7 million barrels-per-day cut. From late 2022 OPEC+ ran deep voluntary cuts to defend prices against weak Chinese demand and rising US shale.
US shale and the loss of pricing power
The shale revolution (hydraulic fracturing and horizontal drilling, scaled from c.2010) made the United States the world's largest crude producer and a net petroleum exporter by 2020, blunting OPEC's leverage: every sustained price rise invites a shale supply response. Candidates should grasp this feedback loop—OPEC+ discipline versus shale elasticity—as the central tension of contemporary oil markets.
Gas markets fractured violently after Russia's February 2022 invasion of Ukraine and the September 2022 Nord Stream sabotage. Europe replaced piped Russian gas with seaborne liquefied natural gas (LNG), largely from the US and Qatar, exposing the price premium of the energy transition's transitional fuel. The episode demonstrated that energy is an instrument of statecraft: supply can be withheld (Russia) or sanctioned (the G7 $60 oil price cap on Russian crude, December 2022, enforced through Western shipping and insurance).
