Asian equities advance as US Treasury bond buybacks fail to soothe Wall Street

Asian equities advanced on Friday as investors evaluated the US Treasury's intervention in the bond market. This regional relief contrasted sharply with Wall Street, where skepticism over elevated borrowing costs and inflation prompted renewed selling across all three major US indexes.

Treasury Secretary Scott Bessent attempted to stabilize markets by pledging to at least double sovereign debt repurchases after the 30-year borrowing cost hit levels unseen since 2007. The announcement initially drove long-term rates down before they quickly recovered on Thursday. Mark Malek of Muriel Siebert and Co dismissed the intervention as a housekeeping move destined to be short-term, at best.

Bessent insisted the department possesses a big toolkit to address yields that he argues are unmoored from financial conditions, blaming thin August trading and heavy corporate issuance. The Treasury chief also predicted that inflation, which has exceeded the Federal Reserve's two per cent target for over five years, will eventually ease. He expects prices to retreat once the United States gets on the other side of the Iran conflict and oil markets stabilize.

Regional markets showed resilience despite the US turmoil, with Seoul outperforming as chipmakers rallied. SK hynix surged over 12 per cent following a US$29 billion share repurchase, while Samsung advanced on reports of an intended capital return valued up to US$79 billion. Hong Kong, Singapore, Wellington and Taipei posted gains, although Tokyo, Sydney and Shanghai declined.

Analysts point to a massive supply of debt as the primary driver of the yield spike, overshadowing the Treasury's buyback efforts. Michael Hewson at MCH Market Insights noted that increased government spending meant buyers would be spoiled for choice, while the AI boom prompted companies like Amazon, Alphabet and Meta to seek as much as US$500 billion in corporate debt. He warned this surplus depresses sovereign debt markets as investors increasingly favor Big Tech over indebted governments.

Uncertainty was further compounded by Federal Reserve Chair Kevin Warsh, who refused to provide forward guidance on monetary policy. Traders are now looking to his speech at next week's Jackson Hole meeting for clarity on future interest rate decisions. Meanwhile, the yen strengthened against the dollar after Japanese inflation accelerated on higher oil prices, potentially giving the central bank room to hike rates next month.
