WTI Houston's premium to WTI in Midland, Texas, is set to hold at 50¢/bl or wider in 2025, boosted by swelling volumes headed toward the Gulf coast as Houston grows in importance as a center for price discovery.
The locational spread between WTI Houston and Midland rose steadily throughout 2024, averaging 49¢/bl year-to-date and widening as high as $1.41/bl during the June trade month as the 1.5mn b/d Wink-to-Webster pipeline was taken offline for repairs. In 2023, the spread averaged 21¢/bl.
Trading activity for WTI at Oneok's Magellan East Houston (MEH) terminal — both in the physical and financial markets — climbed to all-time highs in 2024. Reported trade month volumes for WTI Houston swelled to 1.26mn b/d during the December trade cycle, a high for the year, and just 0.8pc below its previous record. On 16 December, WTI Houston trade closed the day at 153,000 b/d for the January trade cycle, the highest single-day trade volume in the history of Argus assessments of the grade.
In financial markets, WTI Houston trade activity broke records in 2024, with open interest on CME's WTI Houston futures contract climbing to an all-time high of 412,519 lots — each 1,000 bl — on 21 November.
MEH demand up despite export slowdown
Trading activity broke records even as US crude exports slowed in the latter half of 2024 on Chinese economic woes that dampened Asian demand. New Chinese stimulus initiatives, namely relaxed fiscal and monetary policy, are meant to reverse that trend, but it remains to be seen if the efforts will work.
Further challenges weighing on the US export market are a strengthening dollar combined with a high degree of uncertainty surrounding president-elect Donald Trump's proposed tariff plans, which feature ratcheting-up trade tensions with China even more.
Multiple projects to add Permian takeaway capacity at the Texas Gulf coast are in various stages of planning, which could eventually open the window for ever-larger WTI export volumes, and further support WTI Houston against Midland. But industry participants have grown skeptical of the need for new export terminals or other projects.
Midstream companies showed little enthusiasm for pitching new coast-bound pipelines from the Permian basin in their end-of-year investor reports. Key firms previously sought more takeaway capacity before the Covid-19 pandemic, when WTI Houston premiums to WTI in Midland consistently topped $1/bl, which would help recoup pipeline construction costs. As it stands, the roughly 3mn b/d total available pipeline capacity from the Permian basin to the Houston area is likely to remain static in coming years.
This status quo for onshore infrastructure will help prop open the Houston-Midland WTI premium for the coming year, even if export demand fails to picks up in 2025.
