Asian stock markets opened lower, amid concerns over an AI bubble, pressuring global tech stocks following Wall Street's decline. Investors are watching Chinese economic data and the Bank of Japan (BOJ) meeting to assess the economic outlook towards the end of the year.

December 15, 2568 Asian stock market Trading opened mostly in negative territory this morning (December 15, 2568), following the downward trend of the New York stock market last Friday (December 12), amid investor concerns about the risk of a bubble in the artificial intelligence (AI) industry. This comes after earnings reports from major tech companies began reflecting uncertainty about the future profitability of investments in this sector.

The Nikkei index in Japan opened at 50,352.09 points, down 484.46 points or -0.95%. The Shanghai Composite index in China opened at 3,865.40 points, down 23.95 points or -0.61%. The Hang Seng index in Hong Kong opened at 25,718.14 points, down 258.65 points or -1%, reflecting selling pressure on technology stocks and stocks sensitive to global economic trends.

Other regional stock markets moved in a similar direction, with Australia's S&P/ASX 200 opening down 0.66%, while South Korea's KOSPI index plummeted 2.16% due to pressure on technology and chip stocks, which are directly affected by the negative investment climate in the United States.

Asian investment sentiment was pressured by a decline in the New York stock market on Friday, after Broadcom, a major US chipmaker, warned that future profits could slow. This reignited concerns about the return on investment and sustainability of the rapidly expanding AI sector. Furthermore, Oracle, a major software and cloud company, reported weaker-than-expected earnings prospects, reinforcing investor caution towards large-cap technology stocks.

Investors are also closely watching the release of key Chinese economic data this morning to assess the outlook for the domestic economy's recovery. The National Bureau of Statistics of China is scheduled to report November's housing price figures, industrial production, retail sales, fixed asset investment, and the unemployment rate. This data will play a crucial role in shaping economic policy direction and market sentiment in the coming period.

Meanwhile, in Japan, the Bank of Japan (BOJ) released its Tankan survey indicating that the confidence index among large manufacturers rose to 15 in the fourth quarter of 2025 from 14 in the third quarter, driven by increased confidence among oil and coal producers. This data has increased market expectations that the BOJ may consider raising interest rates at its meeting this week.

However, the confidence index for non-manufacturing companies, which includes the service sector, stood at 34 in the fourth quarter, unchanged from the previous quarter. This reflects the fact that the recovery of domestic demand remains gradual amidst global economic uncertainty and the monetary policy direction of major economies.
