AI-driven Hong Kong stock inflows from mainland China slow as investor options multiply

Mainland Chinese investment into Hong Kong stocks has decelerated significantly in 2026, according to analysis from BNP Paribas. Southbound inflows through the Stock Connect cross-border trading system have reached approximately $30 billion year-to-date, a marked slowdown from the record $180 billion invested throughout 2025. Bank strategists emphasize this reflects evolving market dynamics, not a retreat from Chinese assets. "Investors are still positive on China’s AI story," said Jason Lui, BNP Paribas's head of Asia-Pacific equity and derivative strategy, noting the key change is that they now have "more options to express those views."

The shift is driven by a fundamental change in the investment landscape. The 2025 rally was largely triggered by the surprise emergence of AI startup DeepSeek, which funneled capital toward major Hong Kong-listed tech giants as the primary AI proxies. In contrast, the past 6-9 months have seen a wave of new listings across both mainland and Hong Kong exchanges, creating more targeted, 'pure-play' AI investment opportunities. Consequently, investors are moving away from broad index bets and toward selective investments in individual AI companies, diminishing the need to channel all AI-themed capital through Hong Kong. Analysts like Kenny Tang Sing-hing also note the slowdown is partly due to the exceptionally high base set by last year's surge.
