Trump Finally Found a Carbon Tax He Can Love

Key Takeaways

• Iran toll $1 per barrel on Hormuz shipments
• Effective carbon tax about $2.3 per ton CO₂
• Only 25% of global oil faces the fee
• Revenue earmarked for IRGC, not climate funds
• Toll could raise VLCC shipping costs by $2 million

Pulse Analysis

The cease‑fire between the United States and Iran has halted a war that threatened the Strait of Hormuz, the chokepoint through which roughly one‑quarter of the world’s crude, LNG and jet fuel flow. During the conflict Iran closed the strait, prompting the worst energy crisis since the 1970s. The peace proposal now calls for joint Iranian‑Omani control and a $1‑per‑barrel toll on every vessel transiting the waterway, payable in Chinese yuan or stablecoins to sidestep U.S. sanctions.

At $1 per barrel the levy translates into roughly $2.33 per metric ton of CO₂, making it a de facto carbon tax far below the $40‑$50 per ton levels advocated by former Republican proposals and the Obama administration’s social cost of carbon. While modest, the fee applies only to oil exiting the Persian Gulf, meaning the burden falls mainly on Gulf producers rather than global consumers. Consequently, the price signal is too weak to drive significant decarbonization, but it does add a measurable cost to crude shipments.

The revenue from the Hormuz toll is slated for Iran’s Islamic Revolutionary Guard Corps, not for climate mitigation or deficit reduction, underscoring the geopolitical dimension of the scheme. For ship owners, a Very Large Crude Carrier carrying 2 million barrels now faces an extra $2 million charge, tightening margins in an already volatile market. The modest carbon price, combined with the ability to pay in yuan, highlights how sanctions‑evasion tactics intersect with emerging climate policy debates, and may prompt other chokepoints to consider similar fees. Analysts warn that such fees could set precedents for resource‑based climate levies worldwide.
