Jornal Do Brasilia - Stocks volatile, oil plunges as trade war cranks higher

US President Donald Trump's sweeping tariffs against trading partners kicked in, triggering strong retaliation from China which slapped a higher 84-percent levy on US goods.

The EU announced reprisals for steel and aluminium tariffs that entered force last month, targeting more than 20 billion euros ($22 billion) of US products including soybeans, motorcycles and beauty products.

Growing fears of weakened demand sent oil prices to four-year lows, with international benchmark Brent North Sea crude briefly dropping under $60.

Paris and Frankfurt fell more than two percent, as goods from the European Union now face a 20 percent tariff when entering the United States.

London slumped 2.1 percent, with Britain having been hit with a 10 percent levy on Saturday.

Most Asian equities markets fell back into the red -- Tokyo closed down 3.9 percent.

Wall Street's main indices opened mixed but then pushed solidly higher, with Trump urging calm.

"BE COOL! Everything is going to work out well. The USA will be bigger and better than ever before!" Trump posted on his Truth Social network.

But any hopes of a last minute roll-back on tariffs were dashed as the United States earlier hit China -- its major trading partner -- with tariffs now reaching 104 percent.

"The world's largest and second largest economies are now locked in a trade war, and neither nation seems willing to back down," said Susannah Streeter, head of money and markets at Hargreaves Lansdown.

Speculation that Beijing will unveil stimulus measures helped Shanghai and Hong Kong stocks buck the downward trend in Asian equities.

Pharmaceutical firms took a heavy hit after Trump said he would be announcing a major levy on the sector.

Europe's most valuable company, weight-loss drug maker Novo Nordisk, and British pharmaceutical giant AstraZeneca both fell around six percent.

"Perhaps even more alarmingly, US Treasury markets are also experiencing an incredibly aggressive selloff... adding to the evidence that they're losing their traditional haven status," said Jim Reid, managing director at Deutsche Bank.

The sharp rise in yields on US government bonds triggered similar increases to borrowing costs in the UK and Japan, as expectations for global growth and spending diminished.

"It feels like no asset class has been spared as investors continue to price in a growing probability of a US recession," Reid added.

The rising yields may be an indication that investors need to sell bonds to cover losing positions in equity markets, which have fallen sharply in recent weeks.

"When a few asset classes come under pressure, losses can pile up for investors and traders who are then forced to sell other investments including haven assets like government bonds," said XTB research director Kathleen Brooks.

Foreign exchange markets were similarly rattled on Wednesday -- Beijing has allowed the yuan to weaken to a record low against the dollar, while the South Korean won also hit its weakest since 2009 during the global financial crisis.

The dollar took a knock, while the yen rose more than one percent.
