Oil Markets and Geopolitics

The United States became the world's largest oil producer in 2018. US gasoline prices still spiked when Russia invaded Ukraine. Domestic production does not mean domestic prices, because oil trades on a global market where the marginal barrel sets the price for all barrels.

Oil is priced globally through benchmark crudes (Brent, WTI) on commodity exchanges. When supply is disrupted anywhere, the global price rises everywhere. OPEC, controlling roughly 35% of global production and 70% of proved reserves, coordinates output to manage prices. Saudi Arabia's role as swing producer (the only country with significant spare capacity it can deploy within weeks) gives it outsized market influence.

Trace the price mechanism. A 2 million barrel-per-day supply disruption in the Middle East raises the global benchmark. US refiners, who could export at the higher global price, charge domestic customers the same. US consumers pay world prices regardless of US production levels.

If the US produces enough oil for its own consumption, why can't it insulate itself from global price shocks?

Exports close the gap. As long as US oil can be exported (legal since 2015), domestic prices track global prices. Price independence would require banning exports, which would crash domestic producer revenues and investment. Energy independence (producing enough) is not the same as price independence (paying less).

Oil's global pricing is why energy geopolitics matters even for major producers.
