WTI Crude Oil and the Brent-WTI Spread, Explained

2. How the WTI price and the spread actually form

WTI is delivered physically at Cushing, Oklahoma, a light, sweet crude of about 39.6 degrees API and roughly 0.24% sulfur, and its reference contract is the NYMEX/CME Light Sweet Crude Oil future; Brent's reference is the ICE Brent future, based on a basket of North Sea grades. Since cargo deliveries began in June 2023, WTI Midland, a Gulf Coast grade, has also counted as a deliverable grade into Dated Brent itself, landed CIF Rotterdam on a standard 700,000-barrel, plus or minus 1%, Aframax tanker, with S&P Global Platts applying a freight adjustment factor of 80% of the shipping cost so a CIF cargo compares fairly with an FOB North Sea one.

Because both benchmarks trade as futures long before delivery, the day-to-day price you read is a futures quote, not a cash handshake. Our spot versus futures entry explains that distinction. What moves the spread itself is mostly US export capacity: the more crude the US Gulf Coast can or must ship abroad, the more Brent has to sit above the US price to make that export worthwhile, and when export logistics are ample, WTI trades closer to Brent.

4. From a 30-dollar discount to near parity: what changed

WTI traded close to Brent for decades, then fell sharply behind it from 2011, when the US shale boom filled Cushing faster than pipelines could drain it, pushing the discount to as much as -30 USD/bbl that September (EIA). New pipeline capacity, including the reversal of the Seaway line, and the lifting of the US crude export ban at the end of 2015, let the two benchmarks converge again; by July 2013 the gap was already down to about -3 to -4 USD/bbl (EIA). Since then, the spread's width has tracked US export capacity more than US supply itself: when Gulf Coast terminals and ships are plentiful, WTI trades close to Brent; when they are not, the discount widens again.

Why the spread barely moves a typical US heating bill the way it moves a European one comes down to which crude each retail market prices off. US heating oil at NY Harbor is quoted, and its refining margin traded, against WTI, on the same NYMEX screen; that margin, the US diesel crack spread, hit a record 106 USD/bbl on 1 September 2026 (TT News). European diesel and heating oil price off Brent-linked gasoil instead. Our middle distillates entry covers how diesel and heating oil share the same refinery stream. Our diesel crack spread entry covers that margin in detail.

6. What the spread does not mean

"WTI went negative" in April 2020 did not mean oil was worthless; it meant that one expiring NYMEX futures contract briefly traded at -37.63 USD/bbl because Cushing's storage tanks were close to full and almost no trader wanted to take physical delivery into that bottleneck (EIA). That is a one-off contract-expiry event, not the ongoing Brent-WTI spread discussed elsewhere on this page, and it has not repeated since.

A second mix-up is the sign: "Brent-WTI spread" conventionally means Brent minus WTI, so a positive number is a Brent premium, the far more common case since 2011; WTI has traded above Brent only in isolated stretches, for instance parts of 2008. And the EIA's own forecast of a roughly 91 USD/bbl Brent average for 2026 and 74 USD/bbl for 2027 (Short-Term Energy Outlook, 9 September 2026, as reported by Rigzone) is exactly that, a forecast, not a number this page treats as a promise.
