European Energy ETFs Rally as Iran-US Strikes Threaten the Strait of Hormuz

Crude oil pushed more than 3% higher on Monday, with West Texas Intermediate trading near $74 a barrel, after the United States launched a fresh round of strikes against Iranian targets and deepened fears over the security of the Strait of Hormuz. Brent crude traded above $79 a barrel. The move extended a rally that had already lifted European-listed energy funds sharply over the week to 10 July: the broad crude oil complex added around 5% for the week, fossil energy funds gained more than 4%, and heating oil, the smallest of the group, surged over 11%.

A Hormuz Standoff and a Widening Strike Campaign

The two sides gave conflicting accounts of the strait's status. Iranian officials said the waterway had been closed until further notice, while US Central Command rejected the claim, maintaining that coalition forces were continuing operations to protect freedom of navigation for commercial shipping. The latest exchange followed further US strikes on Iranian assets after Tehran was said to have attacked a Cyprus-flagged container ship; US forces also intercepted Iranian drones and cruise missiles reportedly aimed at vessels in the region.

Iran, for its part, said efforts to ease tensions were continuing even as it acknowledged the interim peace arrangement had entered a critical phase. US President Donald Trump indicated that the earlier ceasefire arrangement was effectively over, though he left the door open to future negotiations. Over the weekend, explosions were reported near Bandar Abbas and Iran launched drone and missile attacks against US allies including Kuwait, Jordan and Qatar. One strike reportedly hit a Kuwaiti offshore drilling platform, the first direct hit on regional energy infrastructure in weeks. Tanker traffic through Hormuz, the route for roughly a fifth of global crude oil and LNG trade, remained subdued, although some vessels may have continued transiting without transmitting satellite signals. Maritime authorities said the Omani-coordinated southern shipping lane remained operational throughout.

The Shift From Crude to Cracks

Broader equity markets have recently traded as though the oil shock has passed, but market analysts caution that crude prices may be the wrong indicator to watch. The more telling signal is coming from refined product markets: crack spreads, the margin refiners earn turning crude into petrol, diesel and jet fuel, remain extraordinarily elevated. The RBN Energy 3-2-1 crack spread has climbed above $60 a barrel in the past week, among the highest levels on record, pointing to lingering stress further down the supply chain even as crude itself has periodically pulled back.

Part of the reason crude has not moved higher still is China, which appears to be managing demand carefully by drawing on its own inventories rather than competing aggressively for spot barrels; the International Energy Agency has noted significant inventory drawdowns during the Hormuz disruption. Analysts increasingly view China's stockpiling decisions as a new swing factor in global oil balances, alongside a producer side that is fragmenting: the United Arab Emirates' departure from OPEC+ targets production capacity of roughly five million barrels a day by 2027, up from an estimated three to 3.4 million barrels a day in 2025. Saudi Aramco reportedly cut its August official selling price for Arab Light crude into Asia by $11 a barrel, placing it at a discount to the Oman-Dubai benchmark for the first time since the 2020 oil price war. Real yields have been moving higher in the US Treasury market alongside a firmer dollar, a combination analysts note has historically weighed on global growth and tightened conditions for commodity-importing and dollar-indebted economies.

The Week Ahead

With Tehran and Washington reportedly continuing technical and peace talks despite the renewed exchanges, and the IEA warning that prolonged tensions could delay the rebuilding of global oil inventories, the coming week is likely to keep the Hormuz risk premium embedded in crude and product prices. European gas futures have also risen on concern that Gulf LNG exports could face further disruption if the conflict widens, a dynamic worth watching alongside the ETF flows below.

Crude oil did the heavy lifting for the group, with the sub-category's 51% year-to-date gain now comfortably outpacing the broader energy and fossil energy baskets. Heating oil remains the year's standout on a percentage basis, up over 100% year-to-date, though it is by far the smallest fund set by AuM and continues to bleed small amounts of capital even as prices surge, a reminder that outsized returns in a niche corner of the market are not always matched by investor conviction. The crude oil and fossil energy sub-groups also stand out for negative year-to-date flows despite strongly positive year-to-date performance, evidence of profit-taking or hedging activity running alongside the rally rather than pure momentum-chasing.

Fund-by-Fund Detail

WisdomTree WTI Crude Oil (CRUD), the largest fund in the set at $945.0 million, gained 4.105% on the week and pulled in $112.97 million of fresh inflows, easily the largest single allocation across the group. WisdomTree Brent Crude Oil (BRNT), the second-largest at $758.8 million, posted the strongest headline return of the week at 6.383%, yet shed a modest $0.47 million, underlining a currency-and-benchmark divergence: investors added to WTI exposure even as Brent delivered the better weekly print.

VanEck Oil Services UCITS ETF (OIGB) rose 5.745% on the week to $247.9 million in assets, with no net flow activity, and carries a striking 188.67 million of positive year-to-date flows against roughly a 39.5% year-to-date gain, an equity-vehicle exposure to services rather than the commodity itself. Among the smaller, currency-hedged share classes, WisdomTree WTI Crude Oil, EUR Daily Hedged (ECRD) added 3.945% and took in $1.40 million, while WisdomTree Bloomberg Brent Crude Oil (BRNB) gained 6.354% with $0.58 million of inflows and WisdomTree Brent Crude Oil, EUR Daily Hedged (EBRT) rose 4.909% on zero net flow, illustrating how share-class currency exposure produces differing weekly returns even when tracking the same underlying benchmark.

WisdomTree Heating Oil (HEAT), the smallest fund in the set at $3.5 million, was again the week's top performer by percentage, up 11.241%, but recorded a small outflow of $70,490, consistent with the pattern seen at the group level.
