Sawt Falasteen - Stock markets slide on trade war fears as US tariffs begin

The dollar and bitcoin came under pressure, as traders also tracked developments surrounding a deal to potentially end the Ukraine war.

Oil prices dropped after OPEC+ on Monday confirmed plans to hike output from next month.

"The March rally did not last long... after a troika of events knocked market sentiment," noted Kathleen Brooks, research director at trading group XTB.

US tariffs of 25 percent on Canadian and Mexican goods came into effect on Tuesday.

The measure coincided with Washington doubling to 20 percent a tariff already levied on various Chinese imports.

Beijing swiftly retaliated, saying it would impose 10 and 15 percent levies on a range of agricultural imports from the United States.

"There is still some market doubt as to whether all these tariffs will persist for a prolonged period of time," noted Deutsche Bank analyst Jim Reid.

The European Union warned that the tariffs on Canada and Mexico risk "disrupting global trade", urging Washington to reverse course.

"These tariffs threaten deeply integrated supply chains, investment flows, and economic stability across the Atlantic," said EU trade spokesman Olof Gill.

Amid fears that the EU will be the next target, French Economy Minister Eric Lombard insisted that the bloc would be tough in negotiations.

"We have negotiators who are playing hardball, we will play hardball but... we need to reach a balanced deal to protect our economies," Lombard said.

Elsewhere this week, investors hope China will announce a huge economic stimulus package at its annual parliamentary meeting, the National People's Congress.

On Thursday, the European Central Bank is expected to cut interest rates again to try and boost a floundering eurozone economy.

The key scheduled economic event Friday will be US jobs data.
