Christof Rühl argues that diesel shortages and price spikes since July—driven by war-damaged refining capacity in Ukraine and Iran—are exposing the fragility of global energy systems. Despite being the world’s top petroleum producer and diesel exporter, the US faces domestic shortages, prompting consideration of an export ban. Such a move could lower US prices but raise them abroad, affecting key trade partners like Mexico, Chile, and Brazil.
While Trump shifted from threatening a ban to pressuring G7 nations to release strategic reserves and ease sanctions on Russia for export promises, Rühl warns these actions undermine energy security and global economic function. The mere threat of an export ban prompted the G7 to advance strategic reserve releases and pledge not to restrict energy exports among members. The US-Russia deal, which eased sanctions in exchange for export commitments, further politicized energy markets.
Rühl emphasizes that true energy security requires optionality—the ability to replace fuels when needed—not just abundance. He notes that supply shocks have been mitigated by inventories, rerouting, fuel substitution, and demand reduction, echoing Adam Smith’s insight that large markets foster resilience through specialization and substitution. However, political interventions—like the US-Russia deal and China’s relaxed diesel export rules—are overriding market mechanisms, chipping away at system resilience.
The diesel crisis exemplifies how economic policy is increasingly used for geopolitical ends, risking long-term instability even if short-term goals appear met.
