Hang Seng Index Falls Below 18,000: Analyzing the Causes and Solutions to Hong Kong Stocks' Liquidity Crisis

Hang Seng Index Falls Below 18,000: Unraveling the Hong Kong Stocks Liquidity Crisis

Recently, the Hang Seng Index has once again fallen below the key 18,000-point threshold, drawing widespread market attention. As a major financial hub in the Asia-Pacific region, the performance of Hong Kong stocks not only reflects local economic expectations but also mirrors deeper shifts in global capital flows. This article analyzes the causes of the Hang Seng's decline from three dimensions—shrinking trading volumes, southbound capital trends, and international capital movements—and explores potential solutions to the liquidity crisis.

1. Persistent Decline in Trading Volumes Weighs on Market Confidence

Since the start of 2024, the average daily trading volume of Hong Kong stocks has significantly dropped from historical peaks. According to data from the Hong Kong Exchange (HKEX), the average daily turnover in the third quarter of 2024 fell to below HK$100 billion, a sharp decline from over HK$200 billion during the peak in 2021. This contraction in trading volume has directly led to reduced market depth, increased stock volatility, and higher transaction costs for investors. The liquidity squeeze stems from both global macroeconomic uncertainties—such as the Federal Reserve's interest rate path and geopolitical risks—and structural issues within Hong Kong stocks themselves, including downward earnings revisions in sectors like property and technology, which have fueled risk aversion.

2. Southbound Capital: From 'Net Inflows' to 'Structural Divergence'

Southbound capital—mainland Chinese funds investing in Hong Kong stocks via the Stock Connect—has long been a key pillar of liquidity. However, recent trends show clear structural divergence: on one hand, high-dividend, low-volatility state-owned blue chips (e.g., energy and banking sectors) continue to see net buying; on the other hand, growth sectors like technology and consumer goods are experiencing net outflows. According to Wind data, net southbound purchases in October 2024 fell by about 30% month-on-month, with funds favoring short-term trading over long-term allocation. This shift reflects mainland investors' cautious outlook on Hong Kong stock valuation recovery, compounded by factors such as yuan exchange rate fluctuations and the rising appeal of the A-share market.

3. International Capital Flows: Foreign Withdrawals and 'De-risking'

International capital flows are a critical variable in Hong Kong's liquidity crisis. Since 2023, global asset managers have systematically reduced their allocation to emerging markets. According to the Institute of International Finance (IIF), net foreign selling of Hong Kong stocks reached approximately $5 billion in the second quarter of 2024, the highest in nearly three years. This trend is closely tied to the Federal Reserve's high interest rates and a strong US dollar—high rates encourage capital to flow back to low-risk assets like US Treasuries, while geopolitical tensions (e.g., US-China tech rivalry, Middle East conflicts) have prompted some foreign investors to adopt 'de-risking' strategies, reducing exposure to Hong Kong stocks. Additionally, the Hong Kong market is highly sensitive to global liquidity; when the VIX (fear index) rises, foreign investors often first sell liquid Hong Kong stocks.

4. How to Solve the Liquidity Crisis? Short- and Long-term Paths

Addressing Hong Kong's liquidity crisis requires a dual approach combining short- and long-term measures. In the short term, regulators can boost market activity by optimizing trading mechanisms—such as cutting stamp duties and extending trading hours—and encouraging more mainland companies, especially in the new economy, to list in Hong Kong. Indeed, the Hong Kong SAR government announced a reduction in stock stamp duty in August 2024, though its effects will take time to materialize. Over the long term, Hong Kong must enhance its competitiveness: first, by deepening cross-border connectivity with mainland markets, expanding the Stock Connect eligible stocks, and attracting more medium- to long-term capital; second, by improving the quality of listed companies through dividends and share buybacks to boost shareholder returns; and third, by strengthening communication with international capital markets to dispel geopolitical misjudgments and restore foreign investor confidence.

Notably, the 'structural divergence' in southbound capital also highlights the need to optimize Hong Kong's investor base. Currently, retail investors account for a relatively high proportion of trading, while institutional investors—such as pension funds and sovereign wealth funds—are underrepresented. Attracting more long-term capital, such as Middle Eastern sovereign funds and Asian pension funds, to allocate to Hong Kong stocks could help stabilize market liquidity. Moreover, as a key hub for yuan internationalization, Hong Kong could explore launching more yuan-denominated products to reduce the impact of exchange rate risks on capital flows.

5. Outlook: Finding Certainty Amid Volatility

The Hang Seng Index's fall below 18,000 is both a release of short-term market sentiment and a concentrated reflection of long-term structural issues. Looking ahead, the recovery of Hong Kong stock liquidity will depend on multiple factors converging: the start of the Federal Reserve's rate-cutting cycle, clear signals of China's economic recovery, and the implementation of local reform measures in Hong Kong. For investors, while the current market faces challenges, valuations in certain sectors—such as high-dividend state-owned enterprises and AI-related tech stocks—are at historical lows, offering medium- to long-term value. As market observers note, a liquidity crisis is often a process of market cleansing and a starting point for value discovery.
