Star Metro - Asian stocks rally as US Treasury steps in to ease bond fears

The surprise move provided a much-needed shot in the arm for investors worried about a spike in 10- and 30-year yields caused by the prospect of inflation staying elevated, government borrowing, and possible Federal Reserve interest rate hikes.

Soon after the announcement, US equities reversed losses to end higher while the dollar tumbled against its peers as traders breathed a sigh of relief following a fresh bout of selling.

Fears had been surging after the yield on a 30-year US Treasury on Tuesday hit its highest level since June 2007, before the global financial crisis.

"This is probably more about the signal the administration wants to send to the market than the size of the operation -- it's small potatoes vs the $40 trillion US government debt," wrote Neil Wilson at Saxo Markets.

"I see it as a very strong sign that the Treasury has decided higher US yields are unacceptable, and that the recent blowout in the long end is undesirable.

"Clearly, Donald (Trump) is not happy yields have blown out."

On Wall Street, market titans Apple, Microsoft and Amazon enjoyed healthy gains to help lead all three main indexes higher.

And the positive mood boosted Asia, where tech firms -- which rely on debt to pay for their huge AI investments -- were pummelled Wednesday.

Seoul led the charge higher, having been the focus of selling pressure the day before.

The Kospi jumped nearly six percent as chipmaker SK hynix rocketed 12.7 percent, helped by Wednesday's announcement by the firm of a $29 billion share buyback aimed at soothing recent worries. Samsung climbed more than nine percent.

Tech firms also helped Tokyo more than one percent higher, while Hong Kong, Shanghai, Sydney, Taipei, Mumbai, Bangkok, Jakarta and Manila were also well up.

London, Paris and Frankfurt opened lower.

The dollar stabilised after sinking against its peers, while gold jumped back above $4,500 for the first time since early June.

"The key question now is whether the fall in yields can last. If oil prices remain elevated and concerns over US borrowing continue, pressure on the long end of the Treasury curve could return," said City Index's Fiona Cincotta.

Crude prices have been rising for the past two weeks as hopes for a US-Iran deal to reopen the Strait of Hormuz fade -- the deadline for an agreement came up this week. Both main contracts advanced Thursday.

Washington's naval blockade on Iran's ports and Tehran's attacks on commercial ships continue, and Iran's armed forces warned Gulf countries against assisting the US military on Wednesday.

While both sides recently said messages were being exchanged, Trump on Tuesday insisted talks were off, taunting Iran with a social media post depicting the strait as a "NEW U.S. Territory".

Meanwhile, minutes from the Fed's July meeting showed many policymakers believe interest rate hikes will be necessary if inflation does not decline.

Three of the 12 voting members of the Federal Open Market Committee dissented from the majority decision to hold rates steady, instead calling for an increase.

They noted economic activity had continued to expand at a "solid pace", but business investment was concentrated in the AI industry.

Eyes are now on next week's annual meeting of central bankers, economists and finance chiefs at Jackson Hole, Wyoming, where investors will be hoping for some idea about Fed boss Kevin Warsh's thinking on rates.

In company news, the founder of Chinese property giant Evergrande, Xu Jiayin, was jailed for life Thursday and the group fined more than US$2 billion after a high-profile default in 2021.

A court said he had been jailed for "multiple crimes and fined, received a life sentence, with political rights revoked for life and all his personal property confiscated".

It said between 2016 and 2021, Evergrande and Xu as boss "violated national laws by engaging in continuous, large-scale financial fraud and other means to inflate assets and conceal liabilities".
