Jornal Do Brasilia - Asia stocks slide on inflation fears as yields surge

Regional equities tracked losses in Wall Street, where the S&P 500 and the tech-rich Nasdaq posted a third straight day of declines, with the yield on the 30-year US Treasury climbing to levels last seen in 2007.

High energy prices sparked by the Middle East war have fuelled fears of inflation, in turn prompting the bond sell-off.

Trump told reporters at the White House on Tuesday that he had been just "an hour away" from relaunching Washington's attacks on Iran before postponing the order, after weeks of a fragile truce and stalled talks to end the war that began late February.

"You know how it is to negotiate with a country where you're beating them badly. They come to the table, they're begging to make a deal," he said.

"I hope we don't have to do the war, but we may have to give them another big hit. I'm not sure yet."

Iran's army spokesman Mohammad Akraminia warned the Islamic republic would "open new fronts against" the United States if it resumed its attacks.

Trump offered a deadline of several days for resuming strikes if a deal was not agreed.

"I'm saying two or three days, maybe Friday, Saturday, Sunday, something, maybe early next week, a limited period of time," he said.

Since the United States and Iran began their war with Iran, the Strait of Hormuz -- a key energy corridor which normally sees 20 percent of global crude transit through -- has been effectively closed to shipping.

Oil prices above remained above $100 a barrel since then, raising concerns that inflation could remain elevated for longer and erode corporate margins as well as consumer demand.

Across Asia, most major markets were in the red, with Tokyo leading losses as the Nikkei fell more than one percent in morning trade.

Sydney, Hong Kong, Singapore, Shanghai, Wellington, Manila and Kuala Lumpur were also trading down. Seoul and Taipei were ahead.

The retreat comes just days after a tech-driven rally pushed global equities to fresh highs.

But investors are increasingly questioning whether the artificial intelligence-led surge in valuations has outrun underlying fundamentals.

Attention is also turning to upcoming earnings from chip giant Nvidia as investors determine whether huge spending on AI data centres is justified by potential returns.

Gold and silver, typically seen as safe-haven assets, held near recent losses as rising yields reduced the appeal of non-yielding assets.
