President-elect Donald Trump's plans to impose tariffs on imports from Canada could divert most of the crude exported via the 590,000 b/d Trans Mountain Expansion (TMX) pipeline away from US west coast refiners to Asia-Pacific.
Flows from Canada's newest pipeline might shift after Trump, via social media late on Monday, announced plans to slap a 25pc tariff on all imports from Mexico and Canada. TMX, which expanded capacity on the Trans Mountain system to 890,000 b/d and gave Asia-Pacific buyers access to heavy sour crude produced in Alberta's oil sands, would have to direct all its flows to Asia if US west coast demand weakens. Tariffs on crude imports from Canada would force US west coast refiners to turn elsewhere.
Refiners in the region have increased purchases of Canadian grades since the May commencement of the pipeline. Cheaper prices and closer proximity to Vancouver, where TMX crude loads, allowed the heavy sour crudes to find favor along the US west coast. But the proposed tariffs would strengthen TMX prices, no longer making it the cheapest heavy sour option.
About 313,000 b/d of mostly heavy sour Canadian crude has loaded at Vancouver's Westridge terminal in the six months since the pipeline made its debut, according to analytics firm Vortexa. US west coast refiners received around 145,000 b/d since the pipeline came on line in May, up from less than 40,000 b/d a year earlier. Most TMX crude destined for the US west coast has gone to California refiners, with Marathon, Chevron and Phillips 66 emerging as consistent buyers.
Around 34mn bl of TMX crude has loaded for Asia-Pacific, or about 161,000 b/d. China, the largest buyer in Asia-Pacific, has purchased about 83pc of those barrels, Vortexa data shows.
Also, Latin American barrels could see a resurgence after being displaced by TMX in the region.
Latin American medium and heavy sours, like Napo and Oriente, could see a resurgence in demand as well, after TMX displaced those grades. In the first six months after TMX, imports of Napo and Oriente fell by 14pc.
Brazilian and Guyanese crudes could also see higher demand in the region, according to market participants.
But Mexican crude flows could also be limited by Trump's tariffs. Imports from Mexico have been declining since TMX's May commencement, dropping 65pc in the pipeline's first six months of service. But refiners still import the grades, taking roughly 3.5mn bl, or 16,7000 b/d since the pipeline began operating.
