Explain Brent crude (BZ), how it differs from WTI, and what the Brent–WTI spread tells traders.
Brent is the world's oil price
If CL is the American oil benchmark, Brent is the global one. The ticker for Brent crude futures on the ICE exchange is BZ. The contract is named after the Brent oilfield in the North Sea between the UK and Norway, but today it actually prices a basket of similar North Sea grades — Brent, Forties, Oseberg, Ekofisk, and Troll, often shortened to 'BFOET.' The reason traders care is reach: roughly two-thirds of the world's crude trade is priced off Brent, not WTI. If you're tracking the global oil narrative, Brent is the chart that matters.
The mechanical difference between BZ and CL comes down to delivery. CL is physically deliverable at Cushing, Oklahoma — a landlocked storage hub. BZ is cash-settled to a published Brent index at expiration. No barrels change hands. That sounds like a small detail but it matters: WTI's price can get distorted when Cushing fills up or when US export capacity hits a bottleneck. Brent, being waterborne and globally accessible by tanker, tends to price the geopolitical risk premium more cleanly.
Think about what moves the spread. When the US shale boom peaked and Cushing was overflowing, WTI traded at a discount of $10 or more to Brent — there was simply more oil in the US than pipelines could move out. When Middle East tensions flare or shipping lanes get disrupted, Brent often jumps faster than WTI because that risk is priced into seaborne barrels first. When the spread compresses, it often means US export pipelines are catching up and the two markets are well-arbitraged.
Practically, most retail traders pick one benchmark and stay there. CL is more liquid in US morning hours; Brent is more responsive to European and Middle East news. If your day overlaps with London, Brent might be the cleaner read. If you trade US session, CL is where the volume is. Some advanced traders trade the spread itself by going long one and short the other — but that's a separate skillset, and it doubles your transaction costs.
Recap: BZ is Brent crude, the global benchmark on ICE. Cash-settled, prices roughly two-thirds of world crude trade. The Brent–WTI spread is a macro signal about US vs global supply tightness.
