Market Overview

Brent crude — the global oil benchmark — briefly surged to $91.41 a barrel Monday, its highest level since June, as the US conducted its ninth consecutive night of strikes against Iran and the Strait of Hormuz, which handles roughly a fifth of the world's oil and gas, effectively shut down to tanker traffic (Guardian). Iran's Revolutionary Guard claimed two oil tankers were destroyed attempting to transit the strait, and three US service members have now been killed in related incidents, with diplomatic talks through intermediaries described as active but inconclusive. Europe is especially exposed: Morgan Stanley warns that European diesel inventories could fall to their lowest levels since 2015 by November, with refining capacity — not crude supply — identified as the real bottleneck. Oil pulled back slightly below $90 after Iran confirmed ongoing back-channel diplomacy, but with one miscalculation separating the market from $100-a-barrel territory, the geopolitical risk premium in energy prices is anything but priced in.

Ryanair posted a 34% drop in pre-tax profit to €593m for the April-June quarter, as the Middle East conflict drove jet fuel costs sharply higher and made passengers reluctant to commit to bookings — forcing the airline to cut fares 6% just to fill seats (BBC). Hedging — pre-agreed contracts that lock in fuel prices to reduce exposure to market swings — covered most of Ryanair's fuel bill, but unhedged costs more than doubled, and the airline warned its full-year results will be 'highly sensitive' to conflict escalation and unhedged fuel prices. Summer fares for July through September are tracking 'modestly' lower year-on-year, with passengers booking unusually close to departure rather than months in advance — a behavioral shift that makes revenue forecasting nearly impossible. Ryanair shares fell 5% on Monday; the airline is better positioned than most rivals thanks to its cost structure and hedging discipline, but as AJ Bell's Russ Mould put it, visibility right now is 'worse than San Francisco airport when the fog sets in.'

Oil prices swung wildly Monday before settling slightly lower — Brent crude at $88.01 and WTI at $82.24 — after Iran's Foreign Ministry indicated it could pursue negotiations with the U.S., cooling a panic bid that had briefly pushed Brent above $90 on news of American service members killed in ongoing strikes. The U.S. has now conducted nine consecutive nights of airstrikes against Iranian targets in retaliation for attacks on tankers transiting the Strait of Hormuz (a critical chokepoint through which roughly 20% of global oil flows), while Tehran has escalated by hitting Kuwaiti infrastructure and its Houthi allies declared a maritime embargo against Saudi Arabia. Energy Aspects founder Amrita Sen told CNBC the market remains "complacent," warning that depleted global inventories and slowed Hormuz shipping could send crude past $100 per barrel. U.S. gasoline prices have already climbed back to $4 per gallon as crude surges 18% this month, a real-economy pinch that makes diplomatic progress — however tentative — the single most important variable in global markets right now.
