In September, Japanese equities delivered mixed performance amid rising geopolitical tensions in the Middle East, higher global bond yields and evolving monetary policy expectations. The Nikkei 225 outperformed, gaining 0.7%, while the broader TOPIX declined 1.1%, supported by a recovery in AI and semiconductor-related stocks despite weakness across much of the market. Early-month sentiment weakened as escalating regional conflict drove oil prices higher, inflation concerns intensified and the yen strengthened. Markets subsequently recovered as AI-related shares rebounded and pressure from energy prices and currency movements eased, before trading largely sideways towards month-end.
