Devere: Trump’s diesel curbs could hit global economies

Devere, a London-based financial advisory group, warned that proposed diesel curbs from the U.S. administration could ripple through every major economy by raising fuel and transport costs, disrupting supply chains and adding to inflationary pressures.

The advisory issued the warning in a policy note to clients and investors. The proposed measures target emissions from heavy goods vehicles, shipping and some industrial uses by limiting diesel availability and tightening engine standards. Devere said those changes would alter fuel pricing dynamics and raise operating costs for logistics, manufacturing and agriculture firms that rely on diesel.

Devere described how higher diesel prices would feed into broader cost structures. Increased road freight and port handling costs would raise the price of imported goods. Producers that use diesel-powered machinery could see higher input costs. The advisory added that higher transport and production costs could be passed to consumers and contribute to higher consumer price indexes.

The note set out regional effects. Advanced economies with large freight and manufacturing sectors may face margin pressure in energy-intensive industries. Emerging markets that import refined diesel could experience trade-balance strain and currency weakness. Oil-exporting countries might see demand shift away from diesel grades even as demand for other fuels changes. Devere also flagged that supply-chain chokepoints could magnify these effects if companies delay shipments or reroute logistics to avoid higher diesel costs.

On industry responses, Devere wrote that automakers and fleet operators could accelerate investment in electric vehicles and alternative fuels, while shipping firms might adopt cleaner fuel blends or retrofit engines to meet stricter limits. The advisory noted these adjustments require significant capital and time, posing short-term strain for firms unable to switch quickly.

The note identified market transmission channels and policy responses. Diesel futures and refined product spreads could move in response to tighter regulations. Credit conditions for logistics and transport firms could tighten if earnings weaken. Devere recommended businesses run stress tests on fuel-cost scenarios, accelerate efficiency measures and explore hedging. For governments, the advisory suggested contingency planning for potential short-term price shocks, targeted support for vulnerable firms and adjustments to strategic petroleum reserves if diesel supply tightens.

“Stricter diesel controls in the U.S. would not stay confined to American roads and ports,” the note warned. Devere said the scale of economic effects will depend on the final design and timing of any regulations and on how quickly companies adopt alternative fuels and technologies.

Background: Diesel powers long-haul trucking, some rail operations, maritime shipping bunkers and heavy machinery in construction and agriculture. Policies to reduce diesel emissions typically focus on nitrogen oxides and particulate matter and can include tighter emissions standards, restrictions on diesel sales in urban zones or incentives for low-emission alternatives. Changes in diesel regulation in a major market such as the United States can affect refined fuel markets and logistics costs worldwide because of the interconnected nature of global trade and refining networks.
