Viewpoint: Canadian heavy TMX crude to grow into Asia
Houston, 23 December (Argus) — Heavy sour Canadian crude exports are likely to
expand further into the Asia-Pacific market in 2026 as Canadian output increases
and US west coast refinery closures weaken US demand. Around two-thirds of all
Canadian crude exports from the 890,000 b/d Trans Mountain pipeline system were
destined to Asia-Pacific year-to-date November 2025, with the balance heading to
the US west coast. Just over three-quarters of the 375,000 b/d of Canadian heavy
crude exports from Vancouver were destined to Asia-Pacific year-to-date November
2025, according to data from analytics firms Vortexa and Kpler. The balance out
of the Trans Mountain system headed to the US west coast. This is up from a
roughly 60/40 split in the second half of 2024 following the 540,000 b/d Trans
Mountain Expansion (TMX) startup in May of that year. US west coast customers
received 80,000 b/d of heavy sour Canadian crude during the first 11 months of
2025, 25pc less than the second half of 2024. This is despite total heavy
exports from Vancouver averaging 27pc higher this year so far. Heavy crude
exports are expected to keep growing in 2026 as increased western Canadian
production meets limited southbound pipeline capacity to the US. In January
2026, Canadian pipeline operator Enbridge rejected 13pc of heavy and light crude
nominations on its 3.1mn b/d Mainline to the US as Alberta production surges in
the colder months. But the Trans Mountain system has accepted all crude
nominations since TMX came on line in May 2024 and the system has room to export
more crude. Trans Mountain reported that the pipeline ran at 87pc capacity in
the third quarter of 2025 . Canadian crude and condensate production is
projected to average a record-high of 4.85mn b/d in 2026, 80,000 b/d above 2025
levels, according to Argus Consulting, a division of Argus Media. China thirst
for heavy grows Any increase in exports is expected to head towards the
Asia-Pacific region, specifically China. Chinese interest in heavy crude is
expected to grow next year as refineries bring on line increasingly advanced
cracking units to improve petrochemical yields . This increase in petrochemical
output will come at the expense of road fuels, as rising electric vehicle use
and low construction-sector activity hit Chinese gasoline and diesel demand.
Heavy Canadian crude tends to be the most competitively-priced, unsanctioned
option for Chinese refiners. Asia-Pacific buyers more generally have sought
Canadian heavy crude as a substitute for restrained supplies of heavy sour
Venezuelan Merey and Arab Heavy. Saudi Arabia's state-owned Saudi Aramco may be
keeping more heavy crude for refining, while market confidence in Merey supply
is weak following a US seizure of an oil tanker off the coast of Venezuela on 10
December and the US declaring a blockage on Venezuela exports on 16 December.
Meanwhile, shipments of Arab Heavy have dropped by 280,000 b/d to around 560,000
b/d this year, according to Vortexa data. As Asia-Pacific interest in Canadian
crude continues to grow, US west coast demand will continue to fall. On the
heels of Phillips 66 closing its 139,000 b/d Los Angeles, California, refinery,
Valero is likely to shutter its 145,000 b/d Benicia refinery near San Francisco
in April 2026. Valero is evaluating alternatives for its 85,000 b/d Wilmington
refinery in Los Angeles. At the start of 2025, these three refineries made up
23pc of Californian refinery capacity, and combined took 30,000 b/d of Cold Lake
during January-June 2025, according to EIA data. As available Canadian crude
supplies grow, the ability to fully load Aframax vessels at the Westridge Marine
Terminal in British Colombia will allow increased volumes to be exported.
Dredging at the terminal is set to be completed by late 2026 or early 2027.
Draft restrictions limit most Aframax vessels to around 550,000 bl at the
terminal for heavy crude, and 600,000 bl for some lighter crudes. Post-dredging,
those same ships could carry around 700,000-750,000 bl. In the long term, Trans
Mountain is looking to boost pipeline flows to meet the increased shipping
capacity, including the use of drag-reducing agents that should add another
85,000-90,000 b/d by 2027 to pipeline capacity, according to Trans Mountain. By
