Hormuz risk widens spread between Gulf and non-Gulf crude grades

["A widening price gap has emerged between crude oil that must transit the Strait of Hormuz and crude that can move without exposure to regional conflict risk. The divergence stems from renewed tension following the breakdown of the US-Iran ceasefire, with buyers demanding a steep discount for oil vulnerable to potential blockade, drone strikes or missile attacks in the Gulf.", "Iraq, OPEC's second-largest producer, has been particularly affected, with its export infrastructure suffering disruptions tied to the broader conflict involving the US, Israel and Iran. This has forced Gulf-origin grades to price at a significant discount relative to benchmarks such as Brent and WTI, which are currently trading above $107 and near $103 per barrel respectively.", "The scale of the spread — reportedly exceeding $40 per barrel between comparable grades — reflects the market's assessment of chokepoint risk at Hormuz, through which a substantial share of global seaborne crude and LNG passes. Any escalation affecting shipping lanes could further widen this gap or trigger broader price spikes."], "takeaway": "Traders sourcing Gulf-origin crude should factor in a substantial geopolitical risk discount and monitor freight, insurance and shipping route alternatives; a further escalation could sharply reprice both physical cargoes and benchmark futures."
