The Nikkei Stock Average plunged for a second consecutive day on September 11, with afternoon losses widening beyond 1,900 points as rising crude oil prices, Middle East tensions, higher long-term U.S. Treasury yields and the previous day’s U.S. equity decline weighed on sentiment. The index opened the afternoon session at 63,361.04, down 1,909.91 points, after ending the morning at 63,469.39. Investors avoided aggressive buying ahead of the August U.S. Consumer Price Index (CPI), due for release tonight, and next week’s Federal Open Market Committee (FOMC) meeting and Bank of Japan monetary policy decision. Nikkei 225 futures moved narrowly between 63,100 and 63,250 during the lunch break, while the dollar traded around 154.40–154.50 yen. Regional markets also weakened, with Shanghai down approximately 1.8% and Hong Kong’s Hang Seng Index down about 0.8%. Semiconductor-related shares led Tokyo losses, including Resonac Holdings, Advantest, Ibiden, KOKUSAI ELECTRIC and Kioxia Holdings. Mining, shipping and insurance stocks advanced, while nonferrous metals, electric appliances and precision instruments declined. Hotter-than-expected U.S. producer prices, higher Treasury yields and concerns over oil supplies added to the risk-off mood, although firm Dow futures and a weaker yen offered limited support. Japan’s August domestic corporate goods price index rose 7.6% year on year, above the 7.4% median forecast compiled by QUICK. The session also included the September stock-index futures and options special quotation calculation, with QUICK estimating the SQ value at 63,039.49, while KOMPEITO debuted on the Tokyo Stock Exchange Growth Market.
