Investors are watching energy costs, interest rate expectations and developments around AI companies for direction.

Asian semiconductor shares fell after OpenAI signalled a pause, renewing investor concerns that growth in the artificial intelligence sector may be slowing.

The Wall Street Journal reports that the United States has fallen behind in producing memory chips, a critical component for AI and electronics dominated by Asian manufacturers such as Samsung and SK Hynix. The piece argues that tariffs, intended to bolster domestic industry, could raise costs for US chipmakers and equipment buyers, making efforts to rebuild American memory-chip capacity even harder.

South Korean shares fell sharply, with the Seoul market dropping more than 2.5 percent as semiconductor stocks led losses. Chipmakers, a core driver of Korea's export-heavy economy, dragged the benchmark index down, and the slide is drawing attention amid ongoing concerns about the global semiconductor sector and its effect on Asian markets.
