Oil producers in Canada and Mexico will likely be forced to reduce prices and divert supply to Asia if US President-elect Donald Trump imposes 25 per cent from the two countries, traders and analysts said. Two sources familiar with Trump’s plan told that oil would not be exempted from po from Canada and Mexico, despite the US oil industry’s warnings that the policy could hurt consumers, industry and national security. Canada and Mexico are the top two petroleum exporters to the United States, contributing 52pc and 11pc of its gross imports, respectively, data from the US Energy Information Administration . The United States accounts for 61pc of waterborne flows from Canada, and 56pc from Mexico, ship tracking data from Kpler showed. Canadian waterborne crude exports have jumped 65pc to about 530,000 barrels per day (bpd) in 2024, the data showed, after the opening of the expanded Trans-Mountain pipeline to the US and Asia. “The Canadian producers, if they face export constraints, if they’re not able to re-route their barrels that previously were exported to US to other markets, may face deeper discounts and may also suffer some revenue losses,” Daan Struyven, co-head of global commodities research at Goldman Sachs said. Canada and Mexico export mainly heavy high-sulphur crude that is processed by complex refineries in the US and most of Asia. “The impact is all on the heavy grades. What are the US refiners going to do? Even Saudi Arabian Heavy crude is limited,” a Singapore-based trader said, adding that some US refiners can only receive crude via pipelines, limiting their options for imports. “Either the producer or the refiner will have to absorb the tariffs,” he said, adding that Canadian producers will have to discount their oil more to attract demand from Asian refiners and cover long-distance shipping costs. Refining sources in Asia and analysts said they expect to see more Canadian and Mexican oil heading to Asia if Trump imposes the tariffs. “We are likely to see quite some volume going to China and India, where refiners’ configurations are able to refine the crude, said LSEG analyst Anh Pham. TMX exports to Asia have risen in recent months as Asian refiners led by Chinese processors test the new grades. However, Mexican exports are down 21pc to about 860,000 bpd this year. European refiners are less likely to pounce on cheaper Mexican and Canadian cargoes, Energy Aspects analyst Christopher Haines told . Tariffs on Mexico “would potentially free up some crude for Spanish refiners that take Maya, but Asia could easily absorb any volumes not sold into the US Gulf, so there will be competition,” he said, adding that European refiners typically don’t import much Canadian crude. Exports of Mexican crude to Europe have averaged around 191,000 bpd so far this year, 81pc of which was delivered to Spain, according to Kpler. Canadian flows are lower at 85,000 bpd. Still, some traders and Goldman Sachs analysts remain sceptical that Trump would actually impose the tariffs, which he has previously used as a negotiating tool, as doing so would drive inflation for US consumers and refiners.
