**Summary**: US Central Command has officially announced the lifting of the maritime blockade on all Iranian ports and coastal areas, confirming that American forces have ceased enforcement and will no longer impede vessel transit. This operationalizes the previously reported US–Iran MoU and restores full access through the Strait of Hormuz and to Iranian export infrastructure, reinforcing downside pressure on crude and condensate benchmarks and narrowing risk premia.

## Detail

1) What happened:
US Central Command has formally declared that the US has lifted the maritime blockade on Iran, ending all enforcement actions against vessels entering or exiting Iranian ports on the Arabian Gulf and Gulf of Oman. This is framed as implementation of the US–Iran MoU. Multiple corroborating reports in different languages state that US forces will remain in the area only to monitor compliance, not to restrict flows. In parallel, Iran’s Supreme Leader has publicly acknowledged and approved the deal despite reservations, materially reducing headline risk of a rapid reversal.

2) Supply/demand impact:
This marks the transition from de‑facto constrained exports under blockade to normalized flows. Given prior alerts already captured the initial surprise, the incremental news here is confirmation and durability: (a) full maritime access to Iranian ports (oil, petrochemicals, condensate, and products) and (b) political cover from the Supreme Leader that lowers the probability of sudden re‑imposition. Market-wise, this cements the return of at least 1.0–1.5 mb/d of Iranian liquids to the market on a sustained basis versus a sanctions‑constrained baseline, with upside for further incremental volumes as logistics and financing normalize. The risk premium linked to potential Hormuz disruption should compress further by several dollars per barrel relative to pre‑deal levels.

3) Affected assets and direction:
Brent and WTI crude, Dubai benchmarks, and Middle East sour grades (Iranian Heavy, Forozan, etc.) face downward price pressure and curve flattening, particularly on the front end as physical availabilities improve. European and Asian refiners gain access to discounted Iranian barrels, likely widening differentials versus Atlantic Basin grades. Freight rates on key AG–Asia routes could firm modestly on higher volumes, while LNG and LPG flows through Hormuz benefit from lower geopolitical risk premia. FX-wise, sanctions relief plus reconstruction funding expectations are supportive for IRR in offshore/parallel markets and mildly bearish for the USD versus EM energy exporters as global supply fears abate.

4) Historical precedent:
The closest analogue is the 2015–2016 JCPOA implementation, when partial normalization of Iranian exports added roughly 1 mb/d over a year, contributing to a multi‑month bear phase in crude. The current shift is sharper because it follows an explicit naval blockade rather than just sanctions.

5) Duration of impact:
This is a structural, multi‑quarter bearish supply shock for crude and products, though initial price moves may be front‑loaded over days to weeks as markets adjust positioning. Residual tail risk remains around regional conflict escalation, but today’s confirmation plus Supreme Leader backing significantly lowers near‑term reversal risk.

**AFFECTED ASSETS:** Brent Crude, WTI Crude, Dubai Crude, Middle East sour crude differentials, Tanker rates (AG–Asia), LNG freight via Hormuz, USD/IRR (offshore), Energy equities (global E&Ps, oil majors), Gulf sovereign credit spreads
