US President Donald Trump's sweeping trade tariffs sent global markets tumbling

The Saudi stock exchange was down 6.78 percent on Sunday, the worst daily loss since the Covid-19 pandemic according to state media, after sweeping US trade tariffs sent global markets tumbling.
President Donald Trump's tariff offensive unleashed this week has sparked a global stock market rout, also raising fears of a general trade war and recession.
In Saudi Arabia, the state-run Al-Ekhbariya television channel reported online that "the Saudi stock index closed trading down (nearly) 7 percent, losing more than 800 points" on Sunday.
The network called it "the largest daily loss in five years" since the early days of the Covid-19 pandemic, with dozens of Saudi companies including oil giant Aramco in the red.
"Trump's tariffs weighed heavily on global markets, and specifically today on Saudi markets," Al-Ekhbariya reported.
The utilities sector was down 8.4 percent, banking 6.9 percent, telecommunications 5.9 percent and energy 5.29 percent, it added.
Shares in Saudi Aramco -- the crown jewel of the kingdom's economy -- fell 6.2 percent.
State-run financial newspaper Al-Eqtisadiah said that "the Saudi stock market lost more than half a trillion riyals (about $133 billion) in market value during Sunday's trading".
A large portion of the losses was attributed to Aramco shares, with the energy giant's market value falling by "more than 340 billion riyals", according to Al-Eqtisadiah.
Other Gulf markets also took a dive, reflecting global trends as countries around the world grapple with Trump's shock tariffs affecting US allies and rivals alike.
The uncertainty over trade and manufacturing has helped to fuel a days-long panic in global markets.
Stock exchanges in Europe and Asia closed at a loss on Friday, and analysts expect further decline when they reopen on Monday.
