Iran Supreme Leader Backs US Deal, Easing Reversal Risk

Severity: WARNING
Detected: 2026-06-18T18:20:11.408Z

Summary

Iran’s Supreme Leader Mojtaba Khamenei says he approved the US–Iran memorandum of understanding despite reservations, signaling top-level endorsement after reports he was opposed. This materially lowers the risk that the agreement, recent sanctions relief signals, and the lifting of the Hormuz naval blockade will be walked back, reinforcing expectations of higher Iranian oil exports and lower geopolitical risk premia in energy.

Details

  1. What happened: New statements from Iran’s Supreme Leader Mojtaba Khamenei (reports 29, 31, 32) clarify his position on the newly signed US–Iran memorandum of understanding. After earlier messaging suggested opposition, he now explicitly states that he approved the deal "despite reservations" based on assurances from Iran’s president and the Supreme National Security Council. This is critical because in the Iranian system, Supreme Leader endorsement is decisive for the durability of major security and foreign‑policy shifts.

This comes in the immediate wake of the US formally lifting its naval blockade on Iranian ports and the Strait of Hormuz (multiple reports already covered by existing alerts) and public discussion of a large reconstruction fund and potential steps on uranium enrichment odds.

  1. Supply/demand impact: The key market angle is the reduced probability that the deal and associated sanctions relief will unravel due to internal Iranian pushback. With Supreme Leader backing now on record, traders can assign higher confidence that:

This strengthens the structural downside bias for crude benchmarks versus the risk-premium spike that would have followed a visible elite split or repudiation of the deal.

  1. Affected assets and direction:

  1. Historical precedent: Analogous episodes include the 2015 JCPOA phase when markets gradually priced in sustained Iranian barrels only after clear Supreme Leader acquiescence. Then, risk premia in Brent compressed as confidence grew that sanctions relief would stick.

  2. Duration: This is medium‑ to long‑duration. The statement reduces the probability of an abrupt policy U‑turn inside Iran, anchoring expectations that the US–Iran energy and security thaw – and associated supply normalization – will last beyond the immediate news cycle, barring external shocks (e.g., Israeli strikes directly on Iranian export infrastructure).

AFFECTED ASSETS: Brent Crude, WTI Crude, Dubai Crude, Oman Crude, Asian LNG benchmarks, INR, JPY, KRW

US Confirms Iran Blockade End as Nuclear Talks, Managed Hormuz Reopening Recast Oil Risk

At 18:45–18:50 UTC, Washington and Tehran locked in a transition from wartime brinkmanship to negotiated management of the Strait of Hormuz and Iran’s nuclear program. Formal US Central Command confirmation that the naval blockade has ended, Iran’s pledge at 18:50 UTC to tightly schedule vessel flows, and the IAEA chief’s travel for uranium‑dilution talks in Switzerland collectively strip a major supply shock from the oil market’s near-term horizon while reshaping power politics from Tel Aviv to Beijing.

Reports: Massive Ukrainian Drone Barrage Ignites Moscow Kapotne Oil Refinery, Hitting 7 Sites

A Ukrainian drone swarm reportedly struck Moscow’s Kapotne oil refinery around 18:00–19:00 UTC, with fires and ‘pillars of flame and smoke’ seen over the capital and claimed damage at seven refinery locations. The scale and depth of the attack mark a significant escalation in Ukraine’s long‑range campaign against Russia’s energy system, raising fresh questions for oil markets, insurers, and Russian domestic fuel security.

Ukraine has launched its largest drone swarm to date against Moscow, with reports and visuals indicating severe multi-point damage to the Kapotne oil refinery. This heightens risk to Russian refining capacity and exportable product flows, supporting a higher risk premium in refined products and, to a lesser extent, crude.
