Stock markets in the United Arab Emirates tumbled on Monday after Iran warned it could target energy and ​water infrastructure ⁠across the Gulf if U.S. President Donald Trump carries out his threat ‌to strike the country's electricity grid.

After Gulf markets closed, world stocks rallied after Trump said ​he would order the U.S. military to postpone any strikes against Iranian power plants and ​energy infrastructure.

Trump ​on Saturday had threatened to "obliterate" Iran's power plants if Tehran did not fully reopen the Strait of Hormuz within 48 hours. Dubai's main share ⁠index dropped 3% on Monday, led by a decline in heavyweight real estate and telecom stocks. Blue-chip developer Emaar Properties slumped 4.6%, while telecom operator Emirates Integrated Telecommunications fell 4.5%. Top lender Emirates NBD Bank and low cost carrier Air Arabia ​both dropped ‌4.9%.

Abu Dhabi's benchmark ⁠index slipped ⁠1.5% with real estate giant Aldar properties and biggest lender First Abu Dhabi Bank falling 5% ​each.

The Abu Dhabi-listed water and Electricity firm Abu ‌Dhabi National Energy Company (better known as TAQA) declined 4.8%. Heightened ⁠uncertainty fuelled risk aversion, triggering broad declines across most sectors as heavyweight stocks dragged on the overall market, said Joseph Dahrieh, managing director at Tickmill.

"Firms in the banking, real estate, and other sectors continue to maintain strong financial positions, leaving the market well-placed for a recovery once risk aversion fades and investor appetite for risk begins to improve," he said.

ADNOC Gas settled 1.5% lower after the firm said it made temporary adjustments to its ‌production of liquefied natural gas and export-traded liquids in response ⁠to ongoing shipping disruption in the Strait of Hormuz. "Operations ​are continuing safely across ADNOC Gas plc's asset base," ADNOC Gas said.

"Following debris falling near certain facilities, inspections confirmed no injuries and no impact to core processing integrity." The ​Dubai index ‌has now fallen 11% year-to-date, while Abu Dhabi's has declined ⁠5.7%, according to LSEG ​data.

  • ABU DHABI dropped 1.5% to 9,423
