Nikkei Climbs on Chip Rally but BOJ Rate Hike Prospect Caps Gains

• Quick Take: Japan's Nikkei 225 advanced Thursday, led by chip and semiconductor-related stocks, though gains were partially capped by ongoing market concern about Bank of Japan rate hike timing.
• The chip rally reflects continued AI-driven demand for high-bandwidth memory and logic chips, benefiting Japanese names with exposure to semiconductor equipment and advanced packaging.
• BOJ's rate hike prospect introduces a yen strengthening risk that could compress Japanese exporters' overseas earnings when translated back to JPY.

Japan's Nikkei 225 posted gains Thursday as semiconductor-linked equities led the advance. Companies exposed to AI infrastructure chip supply chains—including semiconductor equipment manufacturers, chemical suppliers for chip fabrication, and advanced packaging specialists—outperformed the broader index. The catalyst was a combination of strong after-hours results from US AI chipmakers that signaled continued demand robustness for cutting-edge semiconductor nodes, directly benefiting Japan's upstream chip supply chain dominated by Tokyo Electron, Shin-Etsu Chemical, and Lasertec.

However, gains were moderated by persistent concern about the Bank of Japan's policy trajectory. Recent economic data—including strong wage growth and above-target CPI—has kept alive speculation that the BOJ will raise its policy rate from 0.25% to 0.50% at its July 31 meeting or the subsequent meeting in September. A BOJ rate hike would typically strengthen the yen, which compresses the yen-denominated earnings of Japanese exporters reporting overseas revenues in USD, EUR, and other currencies. Toyota, Sony, and other large exporters are most exposed to this dynamic.

The India-Japan connection runs through tech supply chains and capital flows. Japanese institutional investors (specifically the giant Government Pension Investment Fund, GPIF) have been increasing exposure to Indian equities as part of emerging market diversification. Yen strengthening from a BOJ hike could prompt some repatriation of Japanese capital from EM equities, potentially creating transient outflows from Indian markets. Indian chip design and semiconductor services companies (like SPEL Semiconductor) also watch Japanese equipment maker results as a technology pipeline indicator.
