How Energy Markets Work

Oil and gas prices affect nearly everyone, yet the way they are set can seem mysterious. This is a plain-language explanation of the mechanics — how commodity energy is priced and what moves it — not a guide to trading or investing.

Commodities and benchmarks

Crude oil and natural gas are commodities: broadly standardized products whose price is set by supply and demand rather than by any single seller. Because crude varies in quality and location, the market uses reference grades called benchmarks. West Texas Intermediate (WTI) is the main U.S. crude benchmark, priced at Cushing, Oklahoma; Brent is the leading international benchmark tied to North Sea crude. For natural gas in the United States, the key reference is Henry Hub in Louisiana. Most real-world barrels and cubic feet are priced at a premium or discount to one of these references. The EIA publishes historical spot prices for these benchmarks.

Spot and futures

There are two broad ways energy is priced. The spot price is for delivery now. Futures are standardized contracts to buy or sell at a set price on a future date; they let producers and consumers lock in prices and manage risk, a practice called hedging. The relationship between near-term and longer-dated futures reflects the market's expectations about future supply and demand, storage costs, and more.

What moves oil prices

On the supply side, prices respond to production decisions — including those of large exporting nations and groups that coordinate output — as well as disruptions from conflict, weather, or accidents, and the responsiveness of shale drilling described in our shale guide. On the demand side, the biggest driver is the health of the global economy: growth lifts consumption of fuels, recessions cut it. Because oil demand changes slowly in the short run, even small mismatches between supply and demand can swing prices sharply.

What moves gas prices

Natural gas has traditionally been more local than oil, so weather looms large: cold winters raise heating demand, hot summers raise power demand for air conditioning. Storage levels, pipeline capacity, and, increasingly, LNG exports — which link U.S. gas to global demand, as covered in our natural gas guide — all shape the price at Henry Hub and beyond.

Why prices are volatile

Energy is famously volatile because both supply and demand are inelastic in the short term — neither responds quickly to price. You cannot easily drive less the week gasoline spikes, and a new well takes months to bring online. When a shock hits an inflexible system, price does most of the adjusting. Over longer horizons, high prices encourage more supply and less demand, and low prices do the reverse, which is why energy tends to move in cycles.

Reading the market sensibly

The most useful takeaway is skepticism toward confident short-term predictions: the same experts rarely call every turn. Focus instead on the durable forces — supply capacity, economic growth, weather, storage, and infrastructure — and treat price forecasts as scenarios, not facts.
