US oil tariffs on Canada and Mexico would significantly impact North American crude flows
3 minute read
US oil tariffs on Canada and Mexico would initiate a significant shift in crude flows in North America as higher prices would push a portion of US imports into overseas markets, according to a recent report from Wood Mackenzie.
According to the report “How would Trump tariffs affect North American oil markets?” proposed US tariffs of 10% and 25% on Canadian and Mexican oil products, respectively, would alter crude flows for all three countries. Higher ensuing prices would ultimately affect demand in the US, although the impact is expected to be softer than a more disruptive 25% tariff on Canadian oil.
“A wide range of scenarios are still at play, as the implementation of tariffs has been delayed by a month,” said Dylan White, principal analyst, North American Crude Markets, for Wood Mackenzie. “The uncertainty surrounding US policy is likely to continue; ongoing talks could lead to a lifting of tariffs or could spiral into steeper penalties on oil imports. As the tariffs currently stand, the North American market will see several impacts.”
Impacts on Mexico
In a 25% tariff scenario on Mexican oil, Wood Mackenzie expects Mexico exports would largely shift away from the US and to other outlets in Europe and Asia. This could impact ~600 kb/d of imports from Mexico into the US. However, the blow could be softened by the shutdown of the Lyondell Houston refinery and the start-up of Pemex's Dos Bocas refinery.
“Backfill options for heavy barrels in the US crude slate, especially in the US West Coast and US Gulf Coast, would need to come from waterborne imports via Latin American and Middle East countries,” said White. “Iraq, in particular, flexes the largest alternate pool of heavy crude exports. However, these imports are generally cost disadvantaged compared to nearby Canadian and Mexican heavy supply.”
If a 10% tariff scenario arises for Mexico, Wood Mackenzie expects the impact on shipments to the US would be less severe, although regional prices would still be affected to some degree.
“Steeper tariffs on Mexico would likely shift Mayan imports away from the US, with subsequently tighter heavy balances leading to slightly higher relative heavy prices in the US Gulf Coast,” said White. “Beyond that, we expect the higher tariff costs will get backed into wider crude differentials in Mexico and Canada.”
Impacts on Canada
In a 10% tariff scenario on Canadian oil, Wood Mackenzie expects Canadian crude would continue largely being consumed in the US midcontinent and US Gulf Coast.
“Refineries in the Midcon are landlocked and have limited access to alternate sources of heavy crude and are therefore dependent on Canadian supply,” said White. “However, Canadian outlets to non-US destinations become advantaged. The Trans Mountain Pipeline (including TMX) provides access to the Pacific Basin and would likely facilitate increased shipments of Canadian crude to Asia, and away from the US West Coast, in a tariff scenario.”
Re-exports of Canadian crude via the US are not subject to tariffs and would provide optionality to Canadian barrels transiting the US. However, Wood Mackenzie does not expect a 10% tariff would be substantial enough to shift Canadian barrels away from the US Gulf Coast and into Asia.
Impacts on the US
Wood Mackenzie projects that the tariffs would drive oil demand 50,000 b/d lower in the US by 2026, in part due to modestly higher refined product prices.
Relief from domestic producers is unlikely, as Wood Mackenzie continues to forecast measured US Lower 48 production growth in the years to come, driven by Majors in the Permian. Producers remain cash disciplined; drilling investment in recent years has shown little reactivity to changes in crude prices.
