Iran’s Crude Oil Loadings Drop to Zero in September Under U.S. Pressure

Iran’s crude oil loadings dropped to zero in September, according to tanker-tracking data, marking a dramatic shift under U.S. economic pressure. U.S. Treasury Secretary Scott Bessent confirmed that no new Iranian crude oil was loaded onto tankers during the month, describing it as evidence of the Trump administration’s tightening campaign against the regime’s revenue sources. Data from oil-tracking firms Kpler and Vortexa supported this claim, showing zero loadings in September compared to 220,000 to 255,000 barrels per day in August.

The halt in oil loadings coincides with Washington’s intensified efforts to cut off Iran’s financial and commercial networks. Operation Economic Outcast, launched in August, aims to disrupt the regime’s oil-smuggling networks, sanctions-evasion mechanisms, and financial channels. The U.S. Treasury has expanded sanctions to target Iranian aviation, digital-asset infrastructure, military procurement, and major industrial sectors like automotive and steel.

While no new oil was loaded in September, Iran continues to supply some Chinese customers from crude stored in floating storage in Asian waters. Kpler estimated that around 15 million barrels of Iranian oil were held in these reserves at the end of September. However, these stocks cannot be replenished indefinitely without new shipments from Iranian ports, potentially leading to a revenue crisis for the regime.

The prolonged interruption of oil exports could exacerbate Iran’s economic vulnerabilities, including declining foreign currency access, pressure on the national currency, and difficulties financing imports. The U.S. campaign also aims to prevent Tehran from replacing lost oil revenues through alternative channels. The Iranian regime has historically shifted economic burdens onto its population, and a sustained halt in oil revenue could further intensify shortages and economic instability for ordinary Iranians.
