[ANALYSIS] Iranian state media confirms death of Supreme Leader Khamenei; Iran closes the Strait of Hormuz

• Iranian state television has officially confirmed the death of Supreme Leader Ayatollah Ali Khamenei following Saturday’s US–Israeli “decapitation strike” on his secure residence and office compound in central Tehran.
• Initial denials have been withdrawn, with state media confirming he was killed in the strike.
• The Islamic Revolutionary Guard Corps (IRGC) has declared the Strait of Hormuz closed to international navigation until further notice.
• Major tanker operators and global trading houses have halted crude, fuel and LNG shipments through the waterway.
• Analysts warn of a potential Brent crude move above USD 100/bbl if the blockade persists.
• The Israeli military confirmed it launched an additional wave of strikes on Sunday morning, targeting Iran's ballistic missile and aerial defence systems; Iran launched a fresh wave of missile and drone attacks on Sunday morning
• The technical-level follow-up meeting between the US and Iran, scheduled for March 2 in Vienna, is now cancelled following the escalation of the conflict. The diplomatic agenda was replaced by an IAEA crisis session on Monday morning.

Leadership Decapitation Confirmed

• Iranian state media confirmed that Khamenei was killed in what US and Israeli officials described as a targeted strike on regime leadership.
• The strike reportedly hit his central Tehran compound.
• Ali Shamkhani (Defense Council Secretary) and Mohammad Pakpour (IRGC Commander) are among the confirmed senior casualties.
• The Iranian government has declared 40 days of official mourning and a seven-day national holiday.
• Several members of Khamenei’s family, including a daughter and grandchild, were reportedly killed in the same attack.

Blockade of the Strait of Hormuz

• The IRGC has declared the Strait of Hormuz closed.
• Commercial vessels have reportedly received radio warnings from the Iranian Navy stating that no tankers are permitted to transit the strait.
• Major tanker operators and global trading houses have halted crude, fuel and LNG shipments through the waterway.
• The Strait handles roughly one-fifth of global oil supply, making it the world’s most critical maritime energy chokepoint.

New Wave of Retaliatory Strikes

• On Sunday morning, Iran launched a fresh wave of missile and drone attacks.
• Iranian sources state 27 US bases across the region were targeted, along with Israel’s military headquarters in Tel Aviv.
• Air raid sirens continue across central Israel.
• Explosions have been reported in Doha (Qatar), Dubai (UAE) and Manama (Bahrain).
• The Iranian Red Crescent reports at least 201 fatalities and nearly 750 injuries across 24 provinces inside Iran following the initial strikes.
• Casualty figures remain fluid.

Interim Leadership Structure

Under Article 111 of Iran’s Constitution, a provisional leadership council has been activated.

• The council consists of:
  • Masoud Pezeshkian (President)
  • Gholam-Hossein Mohseni-Eje’i (Head of the Judiciary)
  • A Guardian Council jurist appointed via the Expediency Discernment Council
• This council assumes authority until the Assembly of Experts selects a permanent Supreme Leader.

Permanent Succession Mechanism

The Assembly of Experts (88 senior clerics) is constitutionally responsible for electing the next Supreme Leader.

• Reports indicate Khamenei previously submitted three preferred successor names:
  • Gholam-Hossein Mohseni-Eje’i
  • Asghar Hejazi (long-time chief of staff; status unclear)
  • Hassan Khomeini (grandson of Ruhollah Khomeini)
• Mojtaba Khamenei, long rumoured as a potential successor, was reportedly not formally listed in Khamenei’s final directives.

Emergency Wartime Governance

• Secretary of the Supreme National Security Council of Iran Ali Larijani has reportedly assumed an elevated wartime coordination role overseeing crisis management and nuclear diplomacy.
• Military succession backups have been activated across the IRGC chain of command following senior commander casualties.
• The Strait of Hormuz blockade is understood to be central to the regime’s leverage strategy under the new interim structure.

1) Strait of Hormuz Enforcement

• Desks suggest whether Iran physically interdicts vessels or maintains a de facto blockade via deterrence will determine the scale of energy disruption.
• Sustained closure beyond several days materially raises the probability of triple-digit crude pricing, analysts say.

2) US Response

• Further US naval deployments or direct efforts to reopen the strait could mark an escalation phase.

3) Iranian Leadership Stability

• The speed of the Assembly of Experts’ decision will likely determine regime continuity vs fragmentation.

• Energy: Immediate supply shock risk. Strait of Hormuz closure materially impacts global crude balance assumptions via the supply side of the equation.
• Safe Havens: Gold, US Treasuries, and other traditional havens will likely be supported amid geopolitics.
• Macro: Prolonged blockade increases global recessionary and inflationary risks.

• OPEC-8 are due to meet on March 1st (today), in which they were originally (before the Iranian updates) expected to return 137k BPD of barrels to the market. Reuters reported delegates could now be mulling a much larger hike. Reports suggest potentially 411-548k BPD as a "buffer".  
• That being said, while Saudi Arabia and the UAE have spare capacity, analysts warn this cannot fully compensate if the Strait of Hormuz remains closed, as their main export routes also pass through the blocked waterway.
