Portugal Colonial - Asian equities track Wall St sell-off as US deficit fears grow

A weak auction of 20-year US government debt flashed a warning sign that the bond market was worried about the country's finances, days after Moody's lowered its top-tier credit rating.

The news brought an end to a healthy run-up in recent weeks that was stoked by the China-US tariff detente and signs of progress between the United States and other countries on trade.

Bond yields spiked across the board as investors demanded more interest for holding government debt, signalling their fears about the world's biggest economy -- 30-year Treasuries hit their highest level since late 2023.

The selling came after the auction of 20-year bonds attracted tepid interest, and brought back memories of the sell-off that followed US President Trump's "Liberation Day" tariff blitz last month, which was followed by the White House taking a less aggressive approach.

All three main indexes on Wall Street ended sharply lower.

A tax bill pushed by Trump that is currently going through Congress pairs an extension of the tax cuts from Trump's first presidential term with steep savings in government spending to pay for them.

But many market watchers do not expect the spending cuts in the package to be sufficient to offset the tax cuts, lifting the deficit.

"The proposed tax cuts are raising concerns from economists about the US's fiscal position and there are signs of anxiety in the bond markets about the country's debt burden," said National Australia Bank's Tapas Strickland.

Trump's first-term Treasury Secretary, Steven Mnuchin, warned that "the budget deficit is a larger concern to me than the trade deficit" and called for more spending cuts.

Asian equities also sank, with Tokyo, Hong Kong, Shanghai, Sydney, Seoul, Taipei, Wellington and Manila all in the red.

The dollar also held losses on growing concerns about the US economy, while the uncertainty helped revive demand for safe-haven gold, which was sitting around $3,340 an ounce.

And there are now fears that stocks could be in for another rough ride.

"These higher long-end yields make it a whole lot harder to justify today's equity valuations," said Stephen Innes at SPI Asset Management.

"Tech and growth names -- already stretched -- are staring down the barrel of a tangible equity to rates market repricing, and this could cap the rally fuel that's been driving risk assets since the April tariff detente."

Still, bitcoin broke a fresh record of $110,707 as US lawmakers showed greater bipartisan support for a cryptocurrency bill on the regulation of so-called stablecoins, digital coins whose value is tied to the dollar.

This has sparked fresh hopes for regulatory clarity in the sector, including for bitcoin, which is not directly linked to the dollar.

Oil prices extended losses after data from the US Energy Information Administration showed the country's stockpiles had risen last week.

The news helped reverse a rally in the commodity on Wednesday that was sparked by a CNN report that Israel was planning a strike on Iranian nuclear sites.
