The death of Iran's Supreme Leader Ayatollah Ali Khamenei has plunged the nation and the global energy market into a state of profound uncertainty.
Officially, power has transferred to a three-person interim leadership council as stipulated by the constitution. This council includes the president, the head of the judiciary, and a cleric from the Guardian Council. This move is designed to ensure a smooth, constitutional transition and prevent an immediate collapse of the state apparatus. However, the reality on the ground paints a very different picture, as this formal body appears to be more of a political shield than a center of actual power.
The core of this story is the de facto rearrangement of wartime command. The constitutional process is overshadowed by the simultaneous decapitation of key security figures in US-Israeli airstrikes. This has created a power vacuum that is rapidly being filled by a more pragmatic and powerful duo: Ali Larijani, the head of the Supreme National Security Council (SNSC), and Mohammad Mokhber, a figure with deep ties to the IRGC and control over vast economic networks like Setad.
This power shift didn't happen overnight. There's a clear causal chain leading to this moment. First, the groundwork for Larijani’s ascent was laid in August 2025, when he was appointed not only as the SNSC Secretary but also as the Supreme Leader's personal representative to the council, consolidating immense authority. Second, reports from February 2026 suggested Khamenei had already designated Larijani as a contingency leader, effectively pre-authorizing his emergency powers. Third, Mokhber has a proven track record; he successfully managed the state for 50 days as interim president after President Raisi's death in 2024, demonstrating his capability to mobilize resources and maintain stability.
Therefore, the current situation is best understood as a parallel structure. While the interim council holds constitutional legitimacy, the real decision-making and resource allocation will likely be handled by the Larijani-Mokhber axis, leveraging the SNSC and IRGC networks. This consolidation of power is a direct response to the existential threats of external attack and internal instability, ensuring a centralized, military-style command during a national crisis.
- SNSC (Supreme National Security Council): Iran's top national security policymaking body, chaired by the president but heavily influenced by the Supreme Leader and the IRGC.
- Setad (EIKO): A powerful parastatal holding company in Iran, officially known as the Execution of Imam Khomeini's Order, with vast economic assets under the direct control of the Supreme Leader's office.
