The Nikkei 225 Index fell 0.7% to below 66,000 on Friday, while the broader Topix Index declined 0.25% to around 4,050, reversing gains from the previous session. Global bond yields rebounded as investors questioned whether U.S. efforts to reduce borrowing costs through debt buybacks would offer more than a temporary solution. The 10-year U.S. Treasury yield returned to around 4.7%, erasing its losses from earlier in the week, while Japan’s benchmark 10-year yield ended a two-day decline. Data showing Japan’s inflation rate accelerated for a second consecutive month strengthened the case for a near-term Bank of Japan interest-rate increase. BOJ Governor Kazuo Ueda has previously indicated that officials could normalize policy at a faster pace. Technology shares led the declines, including Advantest, Taiyo Yuden and SoftBank Group. The Nikkei and Topix were on track to lose more than 4% and 3%, respectively, for the week.
