Energy infrastructure across the Persian Gulf came under attack over the weekend of May 16-17, including a nuclear facility in the United Arab Emirates, adding to concerns over regional stability and potential further supply disruptions as the Iran war enters its twelfth week and the Strait of Hormuz remains effectively closed.

Details of the UAE facility strike remain limited, with neither the Emirati government nor U.S. CENTCOM publicly confirming the specific target. Multiple energy trading desks cited the attack as a contributing factor in Monday's whipsaw price action — WTI traded between $108 and $105, and Brent traded between $111 and $102 in the same session as escalation/de-escalation signals competed for trader attention.

The attack comes as the UAE — having formally departed OPEC effective May 1 — has positioned itself as one of the United States' principal security partners in the Gulf. EIA's May Short-Term Energy Outlook incorporates the UAE's OPEC departure and cuts OPEC's 2027 spare capacity forecast to 2.5 million bpd from a prior 3.8 million, given the significant spare capacity the UAE represented.

Iraq, Saudi Arabia, Kuwait, the UAE, Qatar, and Bahrain collectively shut in 10.5 million barrels per day of crude oil production in April, EIA reports. Shut-ins are expected to peak near 10.8 million bpd in May as storage limits force additional producer cutbacks. The ADCOP (Abu Dhabi Crude Oil Pipeline) carries available bypass volumes from the UAE that don't transit Hormuz, but at materially reduced rates compared with pre-conflict.

Saudi Aramco CEO Amin Nasser warned investors on the company's first-quarter earnings call that even an immediate Hormuz reopening would require months for market rebalancing: "If the Strait of Hormuz opens today, it will still take months for the market to rebalance, and if its opening is delayed by a few more weeks, then normalization will last into 2027."

G7 finance ministers meeting in Paris today are addressing the supply disruption directly, with European Commissioner for Economy Valdis Dombrovskis confirming the meeting would reaffirm the need to reopen Hormuz as soon as possible. German FM Klingbeil framed the G7 as "the right framework" for ending the war and ensuring free shipping lanes.
