Gulf stock markets fell on Sunday, May 10, following reports of a drone strike on a commercial cargo ship near Qatar’s coast and additional drone activity detected over Kuwait and the United Arab Emirates, raising concerns about recently established US–Iran ceasefire. No casualties were reported in any of the three incidents. No group immediately claimed responsibility.
A drone set a small fire on a ship off the coast of Qatar, while the UAE and Kuwait each reported separate drones entering their airspaces. The UAE’s Defense Ministry said it shot down two drones and blamed the attack on Iran.
The Incidents
Qatar’s Defense Ministry said a drone targeted a commercial ship coming from Abu Dhabi into a southern port, setting a small fire that was extinguished. The United Kingdom Maritime Trade Operations Centre said the attack occurred 23 nautical miles — approximately 43 kilometres — northeast of Qatar’s capital, Doha. It provided no details on the vessel’s owner or flag state.
In Kuwait, Defense Ministry spokesman Brigadier General Saud Abdulaziz Al Otaibi said hostile drones entered Kuwait’s airspace early Sunday and that forces responded “in accordance with established procedures.” The ministry did not specify where the drones originated.
Iran’s Revolutionary Guard Navy on Sunday reiterated its warning that any attack on Iranian oil tankers or commercial vessels would be met with a “heavy assault” on one of the U.S. bases in the region and on enemy ships.
Market Reaction
Gulf equity markets fell across the board as investors responded to the renewed activity. Dubai’s main share index dropped 0.9%, dragged by a 3.6% slide in budget airline Air Arabia and a 5% plunge in Mashreqbank. In Abu Dhabi, the benchmark index declined 0.3%, with Aldar Properties losing 0.3%.
Saudi Arabia’s benchmark index lost 0.8%, with Al Rajhi Bank falling 1% and Saudi Arabian Mining Company declining 1.4%. The Qatari index was down 0.6%, with Qatar Islamic Bank falling 1.1%.
Milad Azar, market analyst at XTB MENA, said markets were likely to remain sensitive to geopolitical headlines and developments on the ground. “Concerns about the sustainability of the current ceasefire and the resurgence of incidents could keep markets on edge,” he said.
Outside the Gulf, Egypt’s blue-chip index advanced 1.1%, with Commercial International Bank gaining 2.3%.
Oil and Ceasefire Status
Brent crude futures eased $1.38, or 1.2%, to $113.06 a barrel at 1108 GMT, having settled up 5.8% the previous session.
U.S. President Donald Trump has reiterated threats to resume full-scale bombing if Iran does not accept an agreement to reopen the Strait of Hormuz and roll back its nuclear programme. The Trump administration maintained that the ceasefire was still in effect despite Sunday’s incidents.
One of the main sticking points in ongoing negotiations is the fate of Iran’s stockpile of highly enriched uranium. The UN nuclear agency says Iran holds more than 440 kilograms of uranium enriched to up to 60% purity — a short, technical step from weapons-grade levels.
Regional and Economic Impact
The UAE’s non-oil private sector expanded at its slowest pace since February 2021 in April, as the Iran war hammered shipping and tourism, hitting sales and exports alike, according to a survey published on Tuesday.
Daniel Takieddine, co-founder and CEO of Sky Links Capital Group, said UAE equities eased after renewed Strait of Hormuz tensions, but that “resilient local fundamentals and any regional de-escalation could support a return toward previous highs.”
After earlier reported Iranian drone and missile attacks across the UAE — including one that sparked a fire at the key oil port of Fujairah — the UAE said those strikes marked a serious escalation and reserved the right to respond. Fujairah has been critical to UAE oil exports during the war because it sits at the end of the Abu Dhabi Crude Oil Pipeline, which carries crude from inland fields to the Gulf of Oman, bypassing the Strait of Hormuz.
Background
The 2026 Iran-U.S. war began on February 28 with joint U.S.-Israeli airstrikes. A ceasefire was agreed on April 7–8, but fighting has continued sporadically. Iran has mostly blocked the Strait of Hormuz since the war began, causing a global spike in fuel prices and rattling world markets. The U.S. has maintained a naval blockade on Iranian ports since April 13, after talks in Islamabad collapsed. There have been several attacks on ships in the Persian Gulf over the past week, including U.S. strikes on two Iranian oil tankers on Friday after they were accused of trying to breach the blockade. Washington is awaiting Iran’s formal response to a U.S. proposal to end the war, reopen the strait, and roll back Tehran’s nuclear programme.
What Happens Next
Iranian response has not been confirmed by Washington of peace proposal as of Sunday, May 10. The British military has confirmed ships have been hit in the Persian Gulf, with the UK Maritime Trade Operations Centre continuing to monitor the waterway. Iran’s Revolutionary Guard Navy has formally warned of retaliatory strikes on U.S. bases if attacks on its vessels continue. Gulf markets are expected to remain sensitive to any further ceasefire developments, according to XTB MENA. Trump is scheduled to meet Chinese President Xi Jinping in the coming days, with the status of secondary sanctions on Chinese oil buyers linked to Iran likely to feature in those discussions.
