US Hormuz Blockade Threatens Iran's $5bn Oil Revenue

Iran generated approximately $5 billion in oil export revenue in the past month, a figure now directly at risk as the prospect of a US-enforced Hormuz blockade sharpens. The core tension: Iran has continued moving its own crude through the strait while effectively restricting other vessel traffic, a selective closure that has given Tehran short-term revenue insulation even as it weaponizes the chokepoint against others. A full US blockade targeting Iranian exports would collapse that arrangement by cutting off the approximately 20% of global oil trade that passes through Hormuz, with Iran's tanker corridors the explicit target. Tehran's escape options are structurally limited. Its primary workarounds, overland routes, pipeline capacity through Iraq or Turkey, and shadow fleet operations, are insufficient to replace Hormuz-volume throughput at current export levels. Buyers, predominantly Chinese refiners absorbing sanctioned Iranian crude at discount, would face supply disruption and sourcing pressure. The next observable signals are whether Iran accelerates non-Hormuz logistics infrastructure and whether China signals tolerance for the supply interruption or applies backroom pressure on Tehran to de-escalate.
