Iranian domestic sources claim oil exports are uninterrupted and trade continues smoothly, while international reports from Reuters and CENTCOM indicate a sharp disruption of Iranian oil exports due to a US naval blockade and the destruction of Iranian tankers. There is also a direct contradiction regarding the success of IRGC attacks on US vessels, with Iran claiming 'heavy damage' and CENTCOM stating all attacks failed and no US Navy warship was struck.

Here's exactly what each side is claiming.

Iranian outlets

Shana reports that Iran's oil exports 'never stopped' during the '40-day war' and that the Supreme National Security Council (SNSC) emphasizes that the country's oil sales are 'ongoing without disruption' and trade 'continues smoothly.' Fars news agency reported Iran's suspension of a 10% freight charge to ease foreign energy shipping. Iranian state media reported that the Revolutionary Guards attacked two US vessels, eight oil tankers, and 10 'non-compliant vessels' trying to pass through the Strait.

International wires

US Central Command (CENTCOM) confirmed it destroyed five Iranian crude oil tankers on September 8 in response to Iranian missile attacks on a US warship, and stated Iranian claims of striking US military vessels are 'completely false.' Reuters and other international wires report that the US naval blockade has 'sharply disrupted' Iran's seaborne oil exports and that no Iranian crude cargoes have successfully transited the Strait of Hormuz to China since the blockade was reinstated on July 14. International reports also detail the significant decline in Strait of Hormuz traffic.

The disagreement: Iranian domestic sources claim oil exports are uninterrupted and trade continues smoothly, while international reports from Reuters and CENTCOM indicate a sharp disruption of Iranian oil exports due to a US naval blockade and the destruction of Iranian tankers. There is also a direct contradiction regarding the success of IRGC attacks on US vessels, with Iran claiming 'heavy damage' and CENTCOM stating all attacks failed and no US Navy warship was struck.

Direct military conflict between the US and Iran continues to escalate, directly impacting global oil and gas supply routes, driving up prices, and increasing the risk of wider regional instability.

📌 Key developments

Iran's Islamic Revolutionary Guard Corps (IRGC) claimed attacks on two US vessels, eight oil tankers, and ten other 'non-compliant vessels' near the Strait of Hormuz on September 9, following US destruction of five Iranian crude oil tankers on September 8.
Brent crude futures surged above $101 per barrel, reaching $101.28, the highest since July, driven by escalating Middle East conflict and severe supply disruption concerns.
The Strait of Hormuz remains effectively closed to commercial shipping for the 193rd consecutive day, with traffic falling to 6-7 vessels on September 6-9, significantly below the normal 85-100 daily transits.
Iran expanded its 'prohibited zone' for shipping beyond the Strait of Hormuz into parts of the Gulf of Oman and the Arabian Sea, with IRGC warning vessels entering without coordination would face Iranian 'sanctions.'
Iran suspended a 10% freight charge on foreign vessels carrying imported or exported oil, gas, and liquid petroleum products, aiming to reduce costs and encourage foreign fleets amidst the US naval blockade.
OPEC+ lowered its 2026 global oil demand growth forecast for the fifth consecutive month to 380,000 barrels per day, citing the impact of the Iran war.
Houthi forces attacked Saudi energy facilities in southern cities on September 9, causing fires, temporary operational halts, and injuring 73 people, with reports of the Houthis conquering the Yemeni city of Mocha, threatening the Bab al-Mandeb Strait.

💡 Why it matters

The sustained closure and increased militarization of the Strait of Hormuz, coupled with attacks on tankers, directly impacts global oil and gas supply, driving up prices and increasing inflation risks. Iran's efforts to mitigate the blockade through trade mechanisms and freight waivers highlight the severe economic pressure on its energy sector, while its expanded 'no-go zone' signals a hardening stance on maritime control.
