Recent headlines

A series of coordinated US-Israeli airstrikes began on February 28, 2026, targeting Iranian military infrastructure, nuclear program sites, and key leadership figures across the country. The most dramatic outcome of these strikes was the death of Supreme Leader Ali Khamenei, confirmed by Iranian state media on March 1, 2026. Following Khamenei's assassination, an interim leadership council, including President Masoud Pezeshkian, Chief Justice Gholam-Hossein Mohseni-Eje'i, and jurist Alireza Arafi, took charge of state affairs. Iran responded with retaliatory drone and ballistic missile attacks, targeting US military bases and several regional allies, including Israel, Qatar, and the UAE. Reports on March 2, 2026, confirmed Iran's closure of the Strait of Hormuz, a critical global shipping lane, causing immediate surges in oil and gas prices. These military actions coincided with widespread anti-government protests in Iran, which started in late December 2025 due to economic hardship and inflation, re-igniting on February 21, 2026.

What's driving the odds

The market is trying to balance the military pressure from the U.S. and Israel with the sudden loss of the Supreme Leader against the Iranian regime's established process and plan for continuity. An interim leadership council was quickly put in place which aims to manage the transition and show stability. Iranian leaders have also reportedly given decision-making powers to lower-level officials, trying to ensure government functions continue.

Key factors to watch

The Assembly of Experts must elect a new Supreme Leader in 2026, with potential candidates including Mojtaba Khamenei and Ali Larijani. The ongoing US-Israeli military campaign aims to degrade Iran's ballistic missile capabilities and potentially weaken the regime's control. Global economic disruption from Iran's closure of the Strait of Hormuz, including sustained increases in oil prices, remains a significant concern, as Reuters reported on March 4, 2026.

The picture right now

The core unknown is how the interim leadership will navigate the selection of a new Supreme Leader, a process constitutionally handled by the Assembly of Experts. The most likely outcome suggests continued regional tensions and internal security measures, as the regime works to consolidate power in the post-Khamenei era.
