Oil slipped modestly on Wednesday after rallying to near three-week highs, as market participants assessed the implications of the United Arab Emirates' decision to exit the OPEC producer group. The prospective reduction in cartel cohesion tempered upside momentum, but supply-side fears kept losses in check.
Price moves - By 20:16 ET (00:16 GMT), Brent futures were down 0.6% at $110.65 a barrel, while West Texas Intermediate futures declined 0.9% to $99.05 a barrel. Both contracts had climbed more than 3% on Tuesday to approach three-week peaks.
UAE departure from OPEC - The UAE said it will leave OPEC effective on Friday, citing a desire to concentrate on its national interests. The exit represents a notable setback for the producer group at a time when supplies are already under strain. The move places the UAE at odds with Saudi Arabia, which serves as the de facto leader of OPEC.
Observers expect the UAE to raise output over time, given its prior objections to OPEC production quotas. However, any meaningful increase in barrels flowing to market is likely to depend on the reopening of the Strait of Hormuz, which currently constrains seaborne exports.
Strait of Hormuz and geopolitical friction - The Strait of Hormuz remains closed, maintaining a choke point that has disrupted roughly 20% of global oil supplies since late February. That closure has been a central factor behind the extended surge in crude prices. Reopening the channel appears unlikely in the near-term.
Efforts to restart transit through the strait and to reach a cessation of hostilities have so far faltered. Media reports earlier in the week indicated that Iran presented a fresh proposal aimed at reopening the strait and ending the war. The United States was reported to object to that plan because it involved postponing negotiations on Iran's nuclear program.
Meanwhile, U.S. forces have largely maintained a naval blockade of Iran, contributing to an impasse between the two governments.
Outlook - The combination of an OPEC member's imminent departure and a closed Hormuz keeps the market sensitive to any further geopolitical developments. Traders are balancing the prospect of eventual higher UAE production against the immediate constraint on exports through the strait and continued diplomatic uncertainty.
