Most Asian stock indexes were heading for weekly losses on Friday as global bond-market stress persisted, oil prices approached a one-month high and inflation concerns intensified. U.S. Treasury yields resumed rising after Wednesday's surprise intervention by the Treasury provided less than a day of relief from selling. Investors pushed the 30-year yield back to 5.25% and the 10-year yield to 4.71%, despite U.S. Treasury Secretary Scott Bessent saying the government could increase Treasury repurchases and considering fiscal consolidation. Analysts questioned whether spending cuts could materially reduce a budget deficit exceeding 6% of gross domestic product, with interest costs alone reaching $1.2 trillion this year. The Nikkei fell 0.8%, taking its weekly loss to 4.4%, while the broader Asia-Pacific index excluding Japan gained 0.5% but remained lower for the week. S&P 500 futures rose 0.1% and Nasdaq futures gained 0.2%. Oil advanced after Bessent said the United States would impose the toughest sanctions in history on Iran, weakening hopes for a deal that would fully reopen the Strait of Hormuz. Brent was last down 0.7% at $93.12 a barrel but remained more than 5% higher for the week. The dollar index was down almost 0.9% for the week at 98.802, while gold held at $4,513 an ounce. Japan's core consumer inflation accelerated in July, supporting expectations for a September Bank of Japan rate increase, although markets already price a quarter-point rise to 1.25%.
