What Moves Oil Prices

Like any commodity, oil prices are fundamentally driven by the balance between supply (how much crude is produced and available) and demand (how much is consumed). When supply exceeds demand, inventories rise and prices typically fall. When demand outpaces supply, inventories draw down and prices rise.

Global oil demand is highly correlated with economic activity. Strong economic growth, particularly in large economies like the US, China, and India, increases demand for transportation fuels, petrochemicals, and industrial uses. Recessions reduce demand as factories slow production and consumers drive less.

The Organization of the Petroleum Exporting Countries (OPEC) and its allies (collectively OPEC+) control a significant portion of global oil production. When OPEC+ decides to cut production quotas, it reduces global supply and typically supports higher prices. Production increases have the opposite effect.

OPEC+ meetings, typically held several times per year, are closely watched by traders. Surprise cuts or increases, or disagreements among members, can cause sharp price moves. Saudi Arabia, as the largest OPEC producer with spare capacity, often plays the role of swing producer.

The US shale revolution transformed global oil markets. Advanced drilling techniques (horizontal drilling and hydraulic fracturing) unlocked vast reserves in formations like the Permian Basin. The US is now the worlds largest oil producer, producing over 13 million barrels per day as of 2024.

Unlike OPEC, US production responds to price signals through the actions of many independent producers. When prices rise, US drillers increase activity; when prices fall, they cut back. This makes US shale a flexible, market-driven source of supply that can moderate price swings.

Weekly inventory data from the US Energy Information Administration (EIA) provides a real-time snapshot of supply and demand balance. Larger-than-expected inventory builds signal weak demand or excess supply and typically pressure prices lower. Surprise draws indicate tight markets and support higher prices.

Crude stocks at Cushing, Oklahoma—the delivery point for NYMEX WTI futures—are particularly important. When Cushing inventories approach minimum operating levels (tank bottoms), it can cause price spikes and market dislocations.

Oil markets are highly sensitive to geopolitical events in major producing regions. Conflicts, sanctions, political instability, or threats to key shipping chokepoints (Strait of Hormuz, Suez Canal) can disrupt supply and cause sharp price spikes.

Examples include the 1973 Arab oil embargo, the 1990 Gulf War, sanctions on Iran and Russia, and recent attacks on Saudi Arabian facilities. Even the threat of disruption can add a risk premium to prices as traders price in potential supply losses.

Crude oil must be refined into usable products (gasoline, diesel, jet fuel). Refinery outages due to maintenance, hurricanes, or equipment failures can tighten product markets even if crude supplies are ample. Refinery margins (crack spreads) reflect this dynamic.

Demand for refined products is seasonal. Gasoline demand peaks in the US summer driving season. Heating oil and diesel demand rises in winter. These seasonal patterns create predictable swings in crude demand and can influence prices.

Oil is priced globally in US dollars. When the dollar strengthens against other currencies, oil becomes more expensive for buyers using foreign currencies, which can reduce demand and pressure prices. A weaker dollar has the opposite effect, making oil cheaper in other currencies and supporting demand.

This inverse relationship between the dollar and oil is not perfect or immediate, but it is a consistent long-term pattern.

Crude oil futures are heavily traded by speculators, hedge funds, and algorithmic traders who do not take physical delivery. Their positioning and sentiment can amplify price moves beyond what fundamentals alone would suggest.

The CFTC Commitments of Traders report shows managed-money (speculative) positioning in WTI and Brent futures. Extreme positioning can signal crowded trades vulnerable to reversals.
