Crude oil prices are driven by global supply decisions (chiefly OPEC+), weekly inventory data, geopolitics and the world economy's appetite for fuel. Natural gas shares some of these drivers but adds a powerful one of its own — weather — and is notorious for some of the wildest price swings in any traded market.
Who or what is OPEC+, and why does it move prices?
OPEC is the Organization of the Petroleum Exporting Countries — a group of major oil-producing nations. Together with allied producers (the "+"), they coordinate how much oil to pump. When OPEC+ announces production cuts, expected supply shrinks and prices tend to rise; when it raises output, the opposite pressure applies. These announcements land suddenly and move prices worldwide within minutes — including in India, where crude contracts on exchanges like MCX track international benchmarks.
Supply shocks don't need a committee, either: an outage at a major field, sanctions on a producing nation, or attacks on shipping routes can tighten supply overnight.
What is inventory data, and why does the market obsess over it?
Every week, the US government publishes how much crude oil and natural gas is sitting in storage. Think of it as the world's fuel warehouse receipt. Inventories rising faster than expected suggests demand is soft — bearish. A surprise drawdown suggests demand is outrunning supply — bullish.
These releases land on fixed weekdays during US hours — which is late evening in India. That is precisely when India's commodity markets are still open, and crude and gas contracts often make their sharpest move of the day in the minutes after the data. Joseph, who trades natural gas, treats those release evenings the way equity traders treat results day: he either has a plan or has no position.
What roles do geopolitics and the economy play?
Oil is the most geopolitical commodity on earth. Wars and tensions involving producing regions, embargoes and shipping disruptions all threaten supply, and prices build in a "risk premium" the moment headlines break — sometimes reversing just as fast when fears ease.
On the demand side, oil is a bet on global activity: recessions cut travel and freight and drag prices down; strong growth does the reverse. Slow-burning forces — fuel efficiency, electric vehicles, energy transitions — shape the multi-year backdrop.
Why is natural gas so much more volatile?
Three structural reasons:
- Weather is the demand curve. Gas heats homes in winter and powers air-conditioning-driven electricity in summer. A revised US cold-front forecast can re-price the entire market in an evening.
- Storage is limited. Unlike oil, gas is hard to store and ship on short notice, so surpluses and shortages hit prices with little cushion.
- Seasonality compounds it. Positioning ahead of winter and summer means the market trades forecasts of forecasts.
The honest note: natural gas has ended careers. Double-digit percentage moves within a day happen, gaps across sessions happen, and a leveraged position on the wrong side of a weather revision can wipe out far more than a beginner expects. Exchange margins on gas are high for exactly this reason — see what margins apply in commodity trading. If you are new to commodities, watching this contract for a few months teaches more, and costs less, than trading it.
Things to keep in mind
- The biggest crude and gas moves usually happen in the Indian evening, around global data releases and headlines — never carry a position into that window casually.
- Inventory reports, OPEC+ meetings and weather updates are scheduled events: know the calendar before you trade the contract.
- Natural gas's volatility is structural, not a phase — position sizes that feel safe in gold can be reckless in gas.
- This article describes drivers for education only; none of it is a prediction of where prices go next.
