Most Asian share indexes were set for weekly declines as renewed selling pushed U.S. Treasury yields higher, despite a surprise Treasury intervention on Wednesday and comments from U.S. Treasury Secretary Scott Bessent about potentially increasing government repurchases of Treasuries and pursuing fiscal consolidation. The 30-year yield rose to 5.25% and the 10-year yield reached 4.71%, levels that raise global borrowing costs, pressure corporate valuations and challenge technology companies financing artificial-intelligence spending. The Nikkei fell 0.8%, taking its weekly loss to 4.4%, while South Korea and Taiwan rose on the day but remained lower for the week. Oil prices reached one-month highs after Bessent said the United States would impose "the toughest sanctions in history" on Iran, dimming hopes of a deal to fully reopen the Strait of Hormuz. Brent was up more than 5% for the week at $93.12 a barrel, while gold gained 3.1% to $4,513 an ounce as the dollar weakened amid concerns over U.S. debt and policy uncertainty. The dollar index was down almost 0.9% for the week at 98.802. Japan's core consumer inflation accelerated in July, strengthening the case for a September Bank of Japan rate hike, although markets already price a quarter-point increase to 1.25%.
