**Summary**: Iran International and other outlets report that President Masoud Pezeshkian has submitted his resignation to Supreme Leader Mojtaba Khamenei, warning that IRGC commanders have effectively taken over the state as U.S. naval forces choke off crude exports. A formal collapse of civilian authority in Tehran during a contested oil blockade would shift decision‑making to security hardliners, raising the risk of Gulf escalation and deeper supply disruption.

## Detail

Iran’s already fragile political center of gravity appears to be tilting decisively toward the security establishment. Between 18:14 and 18:52 UTC on 31 May, Iran International and multiple regional feeds reported that President Masoud Pezeshkian has sent a formal resignation letter to Supreme Leader Mojtaba Khamenei, describing an unprecedented loss of civilian control and a ‘total takeover’ by IRGC commanders. These claims come as independent tanker‑tracking data show multiple National Iranian Tanker Company crude carriers turning back toward Iran over the last 2–3 days under U.S. naval pressure in the Gulf.

The reporting, still unconfirmed by official Iranian state media, is internally consistent: Pezeshkian is said to have used unusually critical language in his letter and to have framed his resignation as a protest against being reduced to a figurehead. A separate English‑language summary at 18:19 UTC states that he cites an IRGC command takeover and the collapse of his ability to manage oil exports. At 18:24 UTC, TankerTrackers noted four NITC tankers carrying a combined 7 million barrels that ‘appear to have attempted to leave Iran’ in recent days but were likely redirected back, matching earlier U.S. Navy blockade statistics already triggering prior alerts.

If Pezeshkian’s move is accepted or even left in limbo, real power over Iran’s external behavior will concentrate further in the Office of the Supreme Leader and the IRGC. For ordinary Iranians, that points to deeper economic hardship: reduced oil liftings, fewer hard‑currency inflows, higher domestic fuel and import prices, and a diminished prospect of sanctions relief. For regional governments, it means that decisions over harassment of shipping, proxy attacks, and missile deployments will be even less constrained by technocratic or economic ministries.

In security terms, an IRGC‑dominated command environment during an active U.S. naval squeeze lowers the threshold for asymmetric retaliation—from mining threats to cyber operations and proxy strikes against U.S., Gulf, or Israeli interests. The release of fresh CENTCOM imagery of carrier air wing operations in the region on 31 May underscores that Washington is prepared to sustain high‑end air and maritime presence while Iran’s internal command chain is under stress. A perception in Tehran that the blockade is driving regime humiliation could incentivize riskier gambits around the Strait of Hormuz, including covert mining or more aggressive use of drones and missiles.

Markets will read this as a structural increase in Iran supply risk rather than a transient disruption. Physical crude buyers, especially in Asia, will reassess reliance on grey‑market Iranian barrels and may bid up alternative grades, supporting Brent and Dubai benchmarks. Tanker insurers and shippers face a sharper risk premium transiting the Gulf and northern Indian Ocean. Currencies of energy‑importing EMs are vulnerable to higher oil prices, while gold and U.S. Treasuries stand to benefit from added geopolitical hedging demand.

Over the next 24–48 hours, key signals will be: (1) whether Khamenei’s office publicly accepts, rejects, or ignores Pezeshkian’s resignation; (2) any moves by the IRGC to announce ‘emergency’ security measures or new rules for shipping in the Strait; (3) changes in AIS behavior of NITC tankers and any new signs of shadow‑fleet rerouting; and (4) U.S. or GCC messaging on rules of engagement in the Gulf. A confirmed power consolidation by the IRGC will require traders and governments to price in a longer‑duration confrontation over Iran’s export capacity and regional posture.

**MARKET IMPACT ASSESSMENT:**
Heightens perceived Iran political and policy risk; supports higher crude and LNG risk premia, safe‑haven flows into gold and USD, and pressure on EM energy importers’ FX. Raises tail‑risk pricing for further Gulf shipping disruption and IRGC‑driven asymmetric responses.
