Iran Warns Gulf States Against Joining US Sanctions, Threatening Retaliation as US Reasserts Claim Over Strait of Hormuz

August 23, 2026 · 🟠 Risk: Elevated

⚖️ Two accounts of the same story

Where sources agree

The dominant narrative across both Iranian state media (via Al Jazeera, ANI, Press TV mentions) and international outlets (Al Jazeera, The Japan Times, The Times of India, DAWN.COM, India Today) is one of escalating rhetoric and economic warfare between Iran and the US. Iran is issuing strong warnings to regional states against aligning with US sanctions, while the US is preparing to implement its 'toughest sanctions yet' and reasserting control over the Strait of Hormuz. Both sides appear to be hardening their positions ahead of Monday's sanctions announcement.

Where sources differ

While Iran claims the Strait of Hormuz is 'closed' and oil shipments are at a 'virtual standstill' due to its actions, international reports indicate a 'surge' in traffic, with over 80% of liquid cargoes using US-backed Omani routes or 'going dark'. This highlights a discrepancy between Iran's asserted control and the international community's efforts to circumvent it. Iranian state-linked reports emphasize Iran's 'position of power and dignity' and 'victory' in the conflict, while international reports focus on the severe economic hardship faced by Iranian families due to sanctions and war. The Iranian narrative aims to project strength and defiance, while international reporting often underscores the internal and external pressures on the regime.

Heightened rhetoric from Iran, including direct threats to target the 'interests' of neighboring countries that align with new US sanctions, coupled with the US President's repeated claims over the Strait of Hormuz and ongoing proxy activity in the Bab al-Mandeb Strait, indicates a significant escalation in economic and geopolitical tensions, increasing the risk of miscalculation or broader conflict.

📌 Key developments

Iran's security chief, Mohsen Rezaei, explicitly warned Gulf countries that any state joining upcoming US sanctions against Tehran would be considered an 'enemy,' and Iran would 'target their interests' in retaliation.
US President Donald Trump reiterated his claim on Truth Social that the Strait of Hormuz is 'NEW US Territory,' a declaration Iran rejects, maintaining the vital waterway remains closed until the US alters its behavior.
Yemeni authorities reported finding and destroying a naval mine planted by the Houthi group in a vital area of the Bab al-Mandeb Strait, while government-aligned forces also destroyed a Houthi explosives-laden boat in the same strait.
Iranian President Masoud Pezeshkian called for an end to the nearly six-month war with the United States, asserting that Iran is in a 'position of power and dignity' and has not compromised on any clause of a Memorandum of Understanding (MoU) aimed at addressing tensions.
The Iranian Foreign Ministry spokesperson, Esmaeil Baghaei, condemned the impending US sanctions as an 'assertion of extraterritorial sovereignty' and a 'declaration of war' on all nations, while Iran's Armed Forces chief of staff, Major General Ali Abdollahi, warned of 'revolutionary, crushing, regret-inducing and devastating responses' to any new threats.
Oil shipments through the Strait of Hormuz remain at a virtual standstill, with Iran threatening to strike unauthorized oil tankers, although Iran granted special permission for some Iraqi oil tankers to pass through the strait.
Chile announced it will close its embassy in Iran from August 31, citing 'preventive' security considerations in the Middle East, without severing diplomatic relations.
[Aug 20] Iraq's government has set a September 30 deadline for Iran-backed militias to disarm, a move backed by US economic leverage, though hardline factions like Kataib Hezbollah and Harakat Hezbollah Al Nujaba continue to refuse, demanding the withdrawal of foreign troops.

💡 Why it matters

For investors, the direct threats to Gulf states and the ongoing closure of the Strait of Hormuz signal increased risk to regional stability and global oil markets. Policymakers face a more challenging environment as Iran's warnings could force difficult alignment decisions for regional actors, potentially destabilizing existing security arrangements. For journalists, the focus shifts to the diplomatic fallout of Iran's threats, the impact of impending US sanctions, and any further maritime incidents, as these developments suggest a prolonged and intensified standoff.
