Nikkei 225 fell 0.1% and TOPIX declined 0.4% in thin year-end trading. Shanghai Composite rose 0.3% while CSI 300 stayed mostly flat. BOJ minutes revealed debate over further gradual rate hikes among policymakers. Low holiday trading volumes kept most Asian indices in narrow ranges.

Markets Trade in Narrow Ranges

Japan’s Nikkei 225 edged down 0.1%, while the broader TOPIX index fell 0.4%. South Korea’s KOSPI dipped 0.2%, and Singapore’s Straits Times Index remained largely unchanged. In China, the Shanghai Composite gained 0.3%, while the CSI 300 stayed mostly flat. Hong Kong’s Hang Seng Index rose slightly by 0.2%, and Australia’s S&P/ASX 200 declined 0.4%, reflecting muted sentiment across the region.

“Trading volumes are thin as many investors close positions before the New Year,” said Keiko Tanaka, a Tokyo-based market analyst. “The lack of conviction kept most indices in narrow ranges despite positive global cues.” Asian markets mirrored the cautious approach seen in Europe and the United States, where holiday trading also remained subdued.

Impact of US Market Gains

Overnight, Wall Street recorded modest gains, with the S&P 500 reaching a record closing high. Large-cap technology stocks led the increase, supported by data showing the U.S. economy grew at a 4.3% annualized rate in the third quarter. Analysts noted that the strong growth reinforced investor confidence in corporate earnings resilience and sustained risk appetite.

However, the positive momentum from U.S. markets only partially carried over to Asia. Investors continued to weigh local economic indicators, and trading volumes remained light. “Global sentiment is positive, but regional markets are restrained due to year-end factors,” said Ravi Menon, an equity strategist in Singapore. Sector-specific trades drove most movements, with financial and technology stocks showing moderate activity.

Bank of Japan Minutes in Focus

Japan’s market attention centered on the BOJ’s meeting minutes released this week. The minutes revealed discussions over whether to maintain gradual rate hikes following a recent increase. Some policymakers advocated continued tightening to keep inflation near the target, while others emphasized monitoring economic growth and wage trends.

“The minutes suggest differing views within the board, which is keeping Japanese equities and the yen range-bound,” said Hiroshi Saito, a senior economist in Tokyo. Investors are monitoring how the central bank may adjust policy next year, which could influence both domestic and regional market movements.

Outlook for Year-End Trading

Asian markets are expected to continue trading with muted volatility during the final week of the year. Analysts expect narrow movements across indices, with sector-specific trades driven by individual stock announcements or corporate earnings updates.

Investors are also likely to maintain positions cautiously, balancing holiday liquidity constraints with ongoing global developments. This approach may keep trading volumes low while preserving stable price ranges across key markets. Overall, Asia’s stock markets remained subdued in thin year-end trading, with the BOJ minutes drawing additional attention.

Regional indices traded within tight bands, reflecting cautious investor behavior and limited follow-through buying, as market participants awaited clearer economic signals heading into the new year.
