Stock markets in the United Arab Emirates declined on Monday after Iran warned it would strike energy and water infrastructure across the Gulf if US President Donald Trump follows through on his threat to attack its electricity grid.
Trump on Saturday threatened to "obliterate" Iran's power plants if Tehran did not fully reopen the Strait of Hormuz within 48 hours, a significant escalation barely a day after he talked about "winding down" the war, now in its fourth week.
After more than three weeks of intense US and Israeli airstrikes that have significantly degraded Iran's missile production and launch capabilities, Tehran continues to demonstrate its ability to retaliate effectively. The ongoing regional conflict has driven sharp increases in energy prices, disrupted air travel, and severely impacted shipping operations through the Strait of Hormuz.
