Natural Gas Liquids (NGLs): What They Are, How They’re Priced, and Why They Matter
Natural gas liquids defined Natural gas liquids (NGLs) are hydrocarbon compounds — primarily ethane, propane, butane, isobutane, and pentane — that are extracted from the natural gas stream at gas processing plants. They are heavier than methane and can be separated and liquefied for individual sale. NGLs are distinct from LNG (which is methane) and […]
Oil Futures Explained: What They Are, How WTI and Brent Work, and What Drives the Price
Oil futures defined An oil futures contract is a standardised agreement to buy or sell a fixed quantity of crude oil at a specified price on a future delivery date. The buyer agrees to take delivery (or cash-settle); the seller agrees to deliver (or cash-settle). WTI (West Texas Intermediate) and Brent crude are the two […]
Sulphur Content in Crude Oil: What Sweet vs Sour Means for Commodity Prices
Sulphur content in crude oil defined Sulphur content is a key quality measure for crude oil. Under the ASTM D4294 standard, crude with less than 0.5% sulphur by weight is classified as “sweet” crude; crude with more than 0.5% sulphur is “sour.” Higher sulphur content requires more complex and costly refinery processing to remove, making […]
Sweet Crude vs Sour Crude Oil: What’s the Difference and Why Does It Matter?
Sweet crude and sour crude defined Sweet crude and sour crude are classifications of crude oil based on sulphur content. Sweet crude contains less than 0.5% sulphur by weight — it is low in sulphur and commands a premium from refiners because it requires minimal desulphurisation processing. Sour crude contains more than 0.5% sulphur and […]
What Drives Oil Prices? The 7 Key Factors Explained
What drives oil prices defined Oil prices are set by the interaction of global supply and global demand, but seven specific factors do most of the work: OPEC+ production decisions, non-OPEC supply growth (especially US shale), demand from China and India, US dollar strength, geopolitical supply disruptions, inventory levels as reported by the EIA, and […]
Brent vs WTI: Key Differences for Commodity Traders
Brent and WTI defined Brent Crude and West Texas Intermediate (WTI) are the two most widely quoted crude oil price benchmarks in the world. Brent is extracted from North Sea oil fields and serves as the global pricing reference for approximately 70–75% of internationally traded crude. WTI is a US-produced crude that serves as the […]
What Is the Coal Supply Chain? Stages, Transport Modes and Key Players
Coal supply chain defined The coal supply chain encompasses every stage from extraction at the mine to combustion at a power station or steel furnace: mining, washing and processing, domestic transport to port, export terminal loading, ocean shipping, receiving port, and final delivery to end user. Two fundamentally different supply chains exist in parallel: thermal […]
The Crude Oil Supply Chain Explained: From Wellhead to Refinery — Upstream, Shipping and Downstream
Crude oil supply chain defined The crude oil supply chain connects the wellhead — where oil is extracted from underground reservoirs — to the refinery, where it is processed into fuel and other products. It runs through gathering pipelines, storage terminals, and ocean tankers before reaching refineries that convert crude into gasoline, diesel, jet fuel, […]
Electricity Wholesale Markets: How Power is Bought, Sold, and Priced Before It Reaches You
Electricity wholesale market defined The electricity wholesale market is the commodity market where electricity generators sell power to utilities, energy retailers, and large industrial buyers before it reaches end consumers. Unlike most commodities, electricity cannot be economically stored at scale, which means supply and demand must be balanced in real time — and the market […]
Emissions Trading Scheme Explained: What It Is, How It Works and What It Means for Global Trade
Emissions trading scheme defined An emissions trading scheme (ETS) — also called a cap-and-trade system — is a market-based mechanism for reducing greenhouse gas emissions. A government or authority sets a limit (the cap) on total CO2 emissions from covered sectors. Companies receive or buy allowances to cover their emissions. Those that emit less can […]
