Brent dips to $91.36 as US-Iran strikes offset by eighth weekly stock draw

Brent settled at $91.36 a barrel after an early rise, while US West Texas Intermediate (WTI) crude eased 10 cents to $88.10. The Financial Times reported that both benchmarks spiked during the Asian morning on news of renewed US strikes on Iranian sites, before fading through the European open. Bloomberg described the session as a tug-of-war between escalating clashes and inventory draws on one side, and profit-taking on the other.

The trigger was a fresh round of US military action against Iranian targets, ordered after the downing of a US Apache helicopter, which put a fragile ceasefire between Washington and Tehran at risk. Platts attributed the intraday retreat to profit-taking offsetting the renewed geopolitical risk premium, a view echoed by LSEG analyst Emril Jamil. Tehran is still blocking most traffic through the Strait of Hormuz, the route for a significant share of the world's oil and LNG, while the US enforces its own blockade on Iranian ports. The US Energy Secretary said on Tuesday that Gulf maritime traffic and Hormuz oil exports are nonetheless increasing as negotiations continue.

The chart below shows Brent over recent months, putting Wednesday's pull-back and the geopolitical risk premium in context.

What this means for UK energy buyers

Hormuz matters to your business beyond the oil price: it carries LNG cargoes that feed European and UK gas hubs, so any sustained disruption tends to pull NBP gas and UK power forwards higher with it. If you're on a fixed contract approaching renewal, the risk is skewed to the upside through the third quarter; flex buyers should treat dips like Wednesday's as potential hedging windows rather than a trend change.

Key figures to watch:

• Brent front-month (currently $91.36 a barrel)
• WTI (currently $88.10 a barrel)
• US crude stocks (down 9.12 million barrels, the eighth consecutive weekly draw)
• US gasoline inventories (down 1.19 million barrels)
• Hormuz transit volumes against the two competing blockades

The supply side is tightening regardless of the fighting. Reuters reported market sources citing American Petroleum Institute (API) data showing US crude inventories fell 9.12 million barrels in the week ending 5 June, the eighth straight draw. The US has been the marginal supplier of crude and products throughout the conflict, boosting exports to Asia and Europe, so shrinking US stocks could constrain those flows and add further price support. ING strategists noted that with no resolution in sight and the global market tightening daily, prices could climb if disruptions persist into the third quarter, when demand typically rises.

Watch whether the ceasefire holds. Tehran has warned it will resume hostilities if Israel continues operations against Hezbollah in Lebanon, and any renewed exchange would likely reprice the front of the curve quickly; conversely, a durable agreement and reopened Hormuz traffic would let the risk premium unwind.
