While global markets have managed crude oil disruptions, an acute crisis is emerging in refined products like diesel. A convergence of factors, including the Hormuz closure and Ukrainian strikes on Russian refineries, is creating severe, overlooked strain on these specific markets.

In a seemingly contradictory wartime move, the administration is allowing countries like Iran and Russia to sell their oil. The primary goal is to manage the massive political and economic problem of spiking gas prices, even if it means temporarily empowering an enemy.

Donald Trump's plea for Ukraine to stop hitting Russian diesel infrastructure, while seemingly pro-Russia, is a starkly practical take on global economics. He understands that a global diesel shortage causes widespread inflation and hardship that ultimately weakens international support and affects everyone, making it a counterproductive long-term strategy.

Sanctions on major Russian oil companies don't halt exports but instead push them into opaque channels. Russia uses independent traders and restructured ownership to create "unknown" cargos, removing sanctioned company names from documents. This model, proven with smaller firms, maintains export volumes while obscuring the oil's origin.

Before the crisis, US pressure had halved India's imports of Russian crude. The Hormuz shutdown forces India and others to seek alternative supplies, making Russian oil essential again. This geopolitical turmoil has made Moscow its single greatest beneficiary, even prompting sanctions waivers from the White House.

A potential US diesel export ban has a cynical, second-order strategic purpose. By cutting off supply to Europe, the US could inflict enough economic pain to force its allies to pressure Ukraine into a settlement with Russia, achieving US policy goals through indirect economic coercion.

The primary impact of U.S. sanctions on Russian oil is not a reduction in supply but a compression of profit margins. Russia is forced to offer deeper discounts, estimated at $3-$5 per barrel below pre-sanction levels, to compensate buyers for increased logistical and financial risks, ensuring export flows remain stable.

Despite his stated goal of lowering oil prices, President Trump's aggressive sanctions on Venezuela, Iran, and Russia have removed significant supply from the market. This creates logistical bottlenecks and "oil on water" buildups, effectively tightening the market and keeping prices higher than they would be otherwise.

US sanctions on Russian LNG facilities are not primarily about punishing Russia for Ukraine, but are a strategic move in a global "LNG war." The US is using LNG as a tool of foreign policy and national security, meaning these sanctions are unlikely to be lifted even with a peace deal.
