Hang Seng Index Breaches 20,000 Mark: Deep Dive into Hong Kong Stock Liquidity Crisis and Outlook

Hang Seng Index Breaches 20,000 Mark: Hong Kong Stock Liquidity Crisis Resurfaces?

In early 2025, the Hang Seng Index once again fell below the 20,000-point threshold, drawing widespread market attention. This breach of a key psychological level not only signals a deepening technical correction but also reflects underlying liquidity concerns in the Hong Kong stock market. This article examines the current challenges from three perspectives: market sentiment, trading volume evolution, and southbound capital flows, while exploring the root causes and future direction of the Hong Kong Stock Exchange's liquidity issues.

1. The 20,000-Point Level: Collapse of a Psychological Barrier

The Hang Seng Index rebounded to around 21,000 points at the end of 2024, but has since declined continuously in early 2025, eventually breaking below 20,000. Market observers note that this level has historically been seen as the last line of defense for bullish sentiment. In the past, the Hang Seng Index fell below 20,000 in 2016, 2018, and 2020, each time followed by panic selling or strong policy intervention. Prior to this breach, the market had experienced several days of declining volume, with average daily turnover falling below the five-year average, indicating exhaustion of buying power.

From a sentiment perspective, the Hang Seng Volatility Index (VHSI) surged on the day of the breach, reflecting heightened investor uncertainty about the outlook. Meanwhile, the short-selling ratio in Hong Kong stocks approached recent highs, signaling a spread of bearish sentiment. Notably, the breach occurred against a backdrop of the Federal Reserve maintaining high interest rates and a widening China-US interest rate differential, amplifying the pressure from external liquidity tightening on Hong Kong stocks.

2. Shrinking Trading Volume: A Symptom of the Liquidity Crisis

The liquidity challenges in Hong Kong stocks are not new. Since 2023, the average daily turnover on the Hong Kong Stock Exchange's main board has fallen sharply from nearly HK$200 billion in 2021, with most of 2024 seeing turnover in the HK$80-100 billion range. Following the index breach, turnover further contracted to less than HK$70 billion, hitting multi-year lows. According to HKEX data, the main board turnover rate has also dropped below 0.3%, far lower than major global exchanges.

The liquidity drought exhibits multiple characteristics: first, widening bid-ask spreads, with some small- and mid-cap stocks experiencing prolonged periods of no trading, becoming "zombie stocks"; second, rising discount rates on block trades, increasing selling costs for institutional investors; third, a cold IPO market, with Hong Kong IPO fundraising in 2024 declining significantly year-on-year and high break-even rates further dampening capital participation. The HKEX has introduced several measures to optimize market structure, including reducing stamp duty and reforming listing rules, but the effects have yet to fully materialize.

3. Southbound Capital: Can Marginal Inflows Break the Deadlock?

Southbound capital flowing into Hong Kong stocks via the Stock Connect has traditionally been a key stabilizing force. However, recent net purchases have been volatile, with a notable shift in composition. According to Wind data, in the first half of January 2025, cumulative net purchases by southbound capital totaled about HK$15 billion, down from the same period in 2024. Moreover, capital has been concentrated in a few large-cap blue chips like Tencent, Meituan, and China Mobile, with insufficient coverage of small- and mid-cap stocks.

A deeper issue is that southbound capital itself faces outflow pressures. As the A-share market becomes more attractive and the renminbi exchange rate fluctuates, some mainland funds are flowing back to A-shares or diversifying into other markets via QDII. Additionally, the high cost of currency conversion for Stock Connect reduces the expected returns for southbound capital. If southbound capital fails to sustain net inflows, Hong Kong's liquidity situation could worsen.

4. Root Causes and Solutions to the Liquidity Dilemma

The liquidity problem in Hong Kong stocks stems from multiple overlapping factors: first, the Federal Reserve's aggressive rate hikes have driven global capital back to dollar-denominated assets, with Hong Kong's offshore market bearing the brunt; second, the pace of China's economic recovery has fallen short of expectations, with declining corporate earnings undermining valuation support; third, ongoing geopolitical risks have reduced international investors' risk appetite for the Hong Kong market; finally, structural issues within Hong Kong's market itself, such as a high proportion of retail investors, insufficient institutionalization, and incomplete derivative tools, also limit liquidity depth.

Resolving the liquidity dilemma requires a multi-pronged approach. In the short term, regulators could consider further reducing transaction costs, such as cutting stamp duty to zero or simplifying trading mechanisms. In the medium term, accelerating the listing of more high-quality mainland enterprises in Hong Kong could attract long-term capital allocation. In the long term, deepening connectivity with the mainland market, expanding the investable scope for southbound capital, and increasing the scale of renminbi-denominated products are essential. The HKEX has indicated it will actively explore innovative products, such as optimizing Stock Connect ETFs and expanding stock options, but results will take time to materialize.

5. Market Outlook: Crisis or Opportunity?

While the Hang Seng Index's fall below 20,000 has sparked pessimism, historical experience suggests that extreme liquidity tightening often breeds rebound opportunities. Currently, Hong Kong stocks are trading at a global valuation trough, with the Hang Seng Index's P/E ratio falling to about 9 times, the price-to-book ratio below 1, and the dividend yield exceeding 4%. Some value investors are beginning to position themselves on the left side. However, the market still needs to digest liquidity risks in the short term, and the index may oscillate and form a bottom in the 19,000-20,000 range. Investors should focus on signals of a Federal Reserve policy shift, data on China's economic recovery, and subsequent HKEX reform measures.

In summary, the current liquidity crisis in Hong Kong stocks is both a challenge and an opportunity to force reforms. If all parties can coordinate effectively, Hong Kong's status as an international financial center remains difficult to replace. However, if liquidity problems continue to worsen, the market could face more severe volatility. Investors are advised to remain cautious, closely monitor changes in trading volume and southbound capital, and wait for clear trend signals.
