Iran's South Pars Phase 11 reaches full production amid escalating Strait of Hormuz attacks and sustained US sanctions pressure

October 4, 2026 · 🟠 Risk: Elevated

Iran claims its IRGC Navy targeted seven violating tankers in the Strait of Hormuz; the US says its blockade is ironclad and Iran has gotten nothing through.

Here's exactly what each side is claiming.

Iranian outlets

Tehran Times reports South Pars Phase 11 reaching full production as a "domestic breakthrough" and a "leap in Persian Gulf gas production," showcasing "world-class Iranian engineering" and resilience against external pressures. The National Iranian Gas Company emphasizes stability in fuel supply to power plants and industries despite challenges, indicating "high resilience of the country's gas network". Fars News and IRIB, citing the Persian Gulf Strait Authority, report Iran's IRGC Navy targeting seven "violating" oil tankers in the Strait of Hormuz over five days, claiming they were owned or chartered by the UAE and some were using unauthorized routes. IRGC Deputy Commander Major General Mostafa Izadi claims US forces have retreated over 500 kilometers from regional waters due to Iran's military capabilities. Iranian Deputy Parliament Speaker Ali Nikzad asserts the US cannot stop Iran's oil exports.

International wires

Bloomberg and The Independent report that US sanctions and a naval blockade have "stopped completely" Iran's oil exports, pushing domestic inflation past 70-90% and causing the rial to plummet to record lows. The UK Maritime Trade Operations (UKMTO) confirms at least three tanker strikes in the Strait of Hormuz since October 1, without attributing responsibility. US Defense Secretary Pete Hegseth rejected Iran's claim of control over the Strait, stating the US blockade is "ironclad" and traffic is running almost at pre-war levels. The US Treasury Department designated the Russia-linked 'A7 Network' as a "shadow banking network" used by Iran to evade sanctions, including for oil sales.

The disagreement: Iranian state media (Fars, IRIB) report the IRGC Navy targeted seven oil tankers in the Strait of Hormuz, citing "violating" vessels and unauthorized routes. In contrast, US Defense Secretary Pete Hegseth states the American blockade is "ironclad" and that "traffic is running almost at pre-war levels every night," implying Iran's actions have not significantly disrupted shipping or exports.

Ongoing military confrontations and tanker attacks in the Strait of Hormuz pose significant risks to global oil supply and shipping. The US naval blockade continues to severely impact Iran's oil exports and economy, contributing to regional instability.

📌 Key developments

Iran's South Pars Phase 11 has achieved its full nominal production ceiling of 1 billion cubic feet per day (bcf/d) at offshore position B, relying on domestic expertise.
The National Iranian Gas Company reported a 1 billion cubic meter increase in gas delivery to industries and small businesses in the first half of the current year, despite reduced production at South Pars.
Multiple oil tankers have been struck by projectiles in and around the Strait of Hormuz since October 1, with Iranian state media claiming seven vessels were targeted over five days, while the UKMTO confirms at least three incidents.
Brent crude oil prices are hovering around $100 per barrel, influenced by ongoing Middle East tensions and the G7's agreement to release 100 million barrels of emergency oil and diesel reserves.
OPEC+ has delayed its review of members' 2027 oil output quotas until mid-November, citing disruptions to capacity expansion projects across the Middle East due to the "Iran war."
The US Treasury Department on October 1st designated the Russia-linked 'A7 Network' as a "shadow banking network" used by Iran to evade sanctions, including for oil sales and weapons procurement.

💡 Why it matters

The increase in Iran's domestic gas production could bolster its energy independence and regional influence. However, heightened shipping risks in the Strait of Hormuz threaten global oil supply stability and prices. US sanctions continue to pressure Iran's economy, while Iran's efforts to evade them highlight ongoing geopolitical challenges in oil trade.
