In mid-December, the Asia-Pacific markets experienced a collective adjustment. Japan and South Korea's stock markets led the decline first, followed by the A-shares and Hong Kong stocks, all turning green on the screen. This is not an accidental phenomenon but the result of multiple risk factors fermenting simultaneously, with market sentiment collectively venting under pressure from different dimensions.

The biggest source of instability comes from the Bank of Japan. The monetary policy meeting scheduled for December 18-19 is widely expected to raise interest rates by 25 basis points to 0.75%. Why is everyone so nervous about this decision? Essentially, it's because of fear rooted in history. The "unexpected" rate hike by the Bank of Japan in July 2024 is still fresh in memory. At that time, insufficient communication between the central bank and the market, combined with weaker-than-expected U.S. non-farm payroll data triggering the "Sam Law," caused the yen to appreciate sharply, carry trades to collapse, and global financial markets to shake. The current concern fundamentally boils down to policy uncertainty. Capital will naturally move out in advance, which has become the first straw that broke the camel's back for the Asia-Pacific stock markets.

On the other hand, the decline of U.S. tech stocks is also unraveling market narratives. AI concept stocks like Oracle and Broadcom continue to weaken. On the surface, it seems to be an individual stock issue, but in reality, it reflects the market's reassessment of the profitability logic of the entire AI sector. Previously, AI concepts were extremely hot, attracting a flood of capital and sparking a wave of gains. But as leading stocks begin to adjust, investors can't help but ask: does this sector really have genuine profit growth potential? Such doubts have propagated from U.S. stocks to Asia-Pacific, making the already fragile tech sector even more vulnerable.
