Trade wars have long been an instrument of geopolitical and economic leverage, but when applied to the oil and gas industry, they can have far-reaching consequences beyond the immediate economic sphere. The recent energy tariffs introduced by the United States under President Donald Trump mark a significant shift in global oil trade, fundamentally redrawing supply routes and altering pricing dynamics. As tariffs are imposed on key energy partners such as Canada and Mexico, the repercussions will ripple through global markets, affecting trade flows, refining economics, and consumer costs. This article explores the outcomes of these energy tariffs, illustrating the potential winners, losers, and broader economic impacts in a world still adjusting to shifting supply chains.
One of the most immediate effects of the tariffs is rerouting crude oil and refined products. Traditionally, Mexico has been a key supplier of crude to U.S. Gulf Coast refiners. However, with a 25% tariff now imposed on Mexican imports, refiners must seek alternative sources, potentially turning to other Latin American countries like Brazil or even the Middle East. This shift represents one of the most substantial restructurings of crude trade flows since the sanctions on Russian oil following the invasion of Ukraine.
On the other hand, Canada's oil flows will experience a lesser but still notable impact, given the lower 10% tariff. Canadian producers are expected to redirect about 200,000 barrels per day away from the U.S. and toward international markets via the expanded Trans Mountain Pipeline (TMX). This reallocation will inevitably influence pricing dynamics, particularly for Western Canadian Select (WCS), which has already seen a dip in value due to uncertainty about U.S. demand.
The energy tariffs are poised to increase costs across the supply chain, with U.S. refiners forced to pay higher prices for their crude feedstock. Historically, American refiners have relied heavily on heavier crude from Canada and Mexico, which is crucial for producing gasoline, diesel, and other refined products. The tariffs will make these imports more expensive, and refiners will pass on the increased costs to consumers. As a result, American motorists will likely see higher gasoline prices at the pump, further fuelling inflationary pressures in an economy already contending with rising costs in various sectors.
Economists have long warned that tariffs, while designed to protect domestic industries, often lead to unintended consequences. In this case, the tariffs may put an economic strain on consumers and businesses instead of making the U.S. more energy secure. Jorge Leon, head of geopolitical analysis at Rystad Energy, underscores this reality: "Tariffs will increase U.S. inflation no matter how you look at it—this is impacting consumer confidence." Given the U.S.'s status as the world's largest oil producer, higher domestic fuel costs could stoke broader economic challenges, leading to lower consumer spending and business investment.
Beyond the immediate economic consequences, the tariffs will contribute to a strategic realignment of global oil markets. In the short term, European refiners will gain from increased demand for fuel supplies, particularly from U.S. East Coast buyers who must now replace Canadian imports with European diesel. Meanwhile, Latin American and Middle Eastern oil exporters stand to benefit as they fill the void left by Mexican and Canadian crude.
This realignment is also reflected in pricing dynamics. The spread between West Texas Intermediate (WTI) and Brent crude has narrowed significantly as traders anticipate higher domestic prices in the U.S. and a potential glut of oil in international markets. The Brent crude benchmark has already dipped below $70 per barrel, a sign of oversupply concerns outside of the U.S., while traders hedge their bets with bearish options. The global pricing disparity underscores how regional policy decisions can reverberate worldwide, causing unpredictable swings in supply-demand balances.
U.S. refiners are among the hardest hit by the tariffs, particularly those on the Gulf Coast that rely on heavy crude imports to optimise their operations. Isabelle Gilks of Wood Mackenzie highlights, "Refiners on the U.S. Gulf Coast will become less competitive as the cost of feedstock rises, and they have to look elsewhere for heavy barrels." Replacing heavy crude with other sources may require technical adjustments to refining processes, adding additional costs and inefficiencies.
Additionally, the shift in supply chains means that fuel supplies that typically flowed from Canada to the U.S. are becoming uneconomical, leading to their redirection toward Europe, further exacerbating supply tightness in the U.S., especially in regions dependent on specific fuel types. As Neil Crosby from Sparta Commodities points out, even high-sulfur fuel oil (HSFO) markets are affected, with about 260,000 barrels per day now needing to find alternative buyers. These disruptions will contribute to ongoing volatility in refining margins and fuel availability.
The long-term consequences of these energy tariffs extend beyond the immediate market disruptions. By undermining trade relationships with Canada and Mexico—two of the largest energy partners of the U.S.—these policies risk creating geopolitical tensions that could lead to retaliatory measures. Mexico and Canada are already exploring new trade avenues, potentially reducing their reliance on the U.S. energy market altogether.
Furthermore, these disruptions raise questions about the broader resilience of global supply chains in an era of increasing protectionism. If energy tariffs become a normalised tool of trade policy, countries may begin shifting their long-term energy strategies, investing in more diversified supply routes and energy security measures. Such realignments could accelerate global trends toward regionalisation of trade, making markets less efficient but potentially more resilient to geopolitical shocks.

The imposition of energy tariffs by the U.S. under President Donald Trump marks a critical turning point in global oil trade. The redirection of crude flows, rising consumer costs, and the increasing burden on U.S. refiners illustrate how trade wars can have unintended economic consequences. While the tariffs may be politically motivated, their impact extends far beyond national borders, profoundly reshaping supply chains and altering market dynamics.
As stakeholders in the oil and gas industry—ranging from producers to refiners and consumers—grapple with these changes, the need for strategic adaptation becomes evident. The global energy landscape is shifting, and whether these disruptions lead to greater resilience or prolonged market inefficiencies will depend on how businesses, governments, and investors respond to the new trade realities. The question remains: Will these tariffs truly enhance U.S. energy security or inadvertently weaken it by pushing traditional partners away? Only time will tell, but one thing is certain—the era of stable and predictable oil trade flows is over.
