US–Iran memorandum signed, Hormuz traffic normalizing post-blockade
Severity: WARNING

Summary
The US and Iran have signed a memorandum opening a 60-day window to negotiate a final agreement, while ship traffic through the Strait of Hormuz is reportedly returning to normal after a blockade was lifted. This combination reduces immediate supply-risk premia on oil and LNG linked to Hormuz disruption and raises the prospect of future upside in Iranian exports if a full deal is reached.
Details
On 18 June, Presidents Donald Trump and Masoud Pezeshkian signed a memorandum launching a 60-day negotiation window for a comprehensive US–Iran agreement. Concurrently, reports indicate that the Strait of Hormuz, which had been subject to a blockade, is beginning to see a normalization of traffic flows. The Strait is the chokepoint for roughly 17–20 million barrels per day of crude and condensate exports, plus significant LNG volumes from Qatar. Any easing of disruption and signaling toward de-escalation directly affects global energy risk premia.
The immediate effect of the reported lifting of the blockade and resumption of more normal shipping patterns is a reduction in tail-risk pricing for severe supply outages. Spot and prompt Brent and Dubai benchmarks, Middle East sour grades, and LNG spot benchmarks in Asia (JKM) and Europe (TTF via LNG linkage) are all sensitive to Hormuz risk. As vessels regain confidence in transit security and insurance premia ease, physical flows should normalize, alleviating concerns about near-term supply shortfalls for key Asian and European buyers.
The memorandum itself does not yet change sanctions law or Iranian export quotas, but it signals a higher probability that, within months, some sanctions relief could emerge if negotiations conclude successfully. Markets will begin to price in the possibility of incremental Iranian crude and condensate exports (potentially several hundred thousand barrels per day over time) and more transparent petrochemical and LPG flows. Historically, milestones in US–Iran diplomacy—such as the 2015 JCPOA framework agreement—have driven >1–2% daily moves in Brent and related benchmarks, as traders adjust expectations for medium-term supply.
Near term (days to weeks), the dominant effect is the removal of a disruptive blockade at Hormuz and the perceived step back from confrontation, which is bearish for crude and LNG risk premia. Over the medium term (6–24 months), if the memorandum leads to a final deal, the structural impact could be meaningfully bearish for Brent, Dubai, and Middle East spreads, while also tightening heavy/sour differentials globally as Iranian barrels return. Failure of talks, however, would quickly reprice geopolitical risk back into the curve.
AFFECTED ASSETS: Brent Crude, WTI Crude, Dubai Crude, JKM LNG, TTF Natural Gas, Qatar LNG-linked assets, Iranian crude exports, USD/IRR, Middle East sovereign CDS
