UAE Oil Shuttle Trade Under Pressure as Iran Targets 45-Vessel Fleet

Iran’s blacklist of 45 vessels, including tankers owned by the Abu Dhabi National Oil Company (Adnoc), has struck directly at the economic architecture the UAE constructed to maintain oil flows during regional conflict. The move threatens the shuttle trade and ship-to-ship transfer operations that have functioned as a commercial workaround, keeping crude moving despite constraints on traditional shipping routes through the Strait of Hormuz.

The timing is awkward for Adnoc. The company has fully restarted production at Ruwais, the UAE’s largest refinery, which operates at 922,000 barrels per day. The facility was forced offline in March following an Iranian drone strike that caused a fire, after already running at reduced capacity due to shipping disruptions. Bloomberg reports that Ruwais has now been running at full capacity for approximately one month, with exports of diesel, jet fuel, and naphtha recovering to roughly 70 percent of pre-war levels. That recovery now faces a fresh test.

The shuttle trade Iran’s blacklist targets emerged as a practical solution to the economic constraints imposed by regional tensions. Rather than routing crude through traditional channels vulnerable to disruption, the UAE developed a network of vessel-to-vessel transfers to keep product flowing to markets. This system has allowed the country to maintain commercial momentum even as geopolitical risks mounted. The specific mechanics of how Iran’s action will affect this network remain a central question for traders and energy market observers monitoring the region.

Meanwhile, broader trade flows between the UAE and Iran have contracted sharply. Traffic along the once-busy shipping route from Dubai Creek to Iran has largely dried up, according to the Financial Times. This decline reflects not only the impact of increased US economic sanctions but also the Emirates’ deliberate reduction of trade relations with Iran, cutting off access to what was once a vital offshore hub for Iranian commercial activity.

Iran’s action coincides with heightened military tensions. The UAE Defense Ministry intercepted a drone over Emirati waters, with authorities stating the unmanned aerial vehicle had originated from Iran. This incident followed the first direct exchange of strikes between the US and Iran in weeks, with Iran’s armed forces claiming to have targeted US military bases in Jordan and the Al Menhad airbase in the UAE in retaliation for American strikes on Lark Island. UAE authorities disputed that Al Menhad was targeted.

The diplomatic response from Abu Dhabi has emphasized the need for political resolution. Anwar Gargash, diplomatic advisor to the UAE president, stated in a post on X that “the policy of targeting Arab Gulf states and Jordan has proved to be a failure,” and called for “realistic and sustainable political solutions” to the conflict.

For Adnoc and other energy operators, the challenge now lies in maintaining the economic viability of export operations while navigating both the direct constraints imposed by Iran’s blacklist and the broader market uncertainties created by regional instability. The refinery’s return to full production is a significant operational achievement. Yet the vulnerability of the shuttle trade infrastructure that supports crude supply to Ruwais underscores the fragility of energy commerce in the current environment. Traders and investors will be watching closely to determine whether alternative shipping arrangements can be established quickly enough to offset the impact of the blacklisted vessels, and at what cost to margins already squeezed by months of disruption.
