In recent years, the Hong Kong stock market has faced challenges with insufficient liquidity, significantly impacting market efficiency. The latest data shows that, despite monetary policies releasing substantial liquidity, funds have not effectively circulated into the real economy. For example, in April 2023, China’s new social financing recorded negative growth for the first time since 2005, indicating low market fund vitality, unable to support consumption and investment. This situation has led to a decline in investors’ willingness to trade, further weakening market activity.
Against this backdrop, the market maker system in Hong Kong is seen as a critical tool for addressing liquidity shortages. This system not only stabilizes market liquidity but also narrows bid-ask spreads, attracting more investors to participate, thereby enhancing market efficiency and appeal.
The lack of liquidity in the Hong Kong stock market is closely tied to low participation by retail investors. According to market observations, trading in Hong Kong stocks is primarily dominated by institutional investors, with a relatively low proportion of retail investors. This leads to reduced trading activity, especially during periods of low volatility. The low participation of retail investors may stem from the following factors:
Increasing retail investor participation requires strengthening market education, providing more investment tools, and lowering investment thresholds.
Transaction costs are a significant factor affecting market liquidity. Transaction costs in the Hong Kong stock market include commissions, stamp duties, and other related fees, which directly impact investors’ willingness to trade. High transaction costs may lead to the following issues:
According to a Citibank study, recent capital inflows into Hong Kong have reached levels seen during the 2007 bull market peak, indicating ample liquidity. However, the influx of hot money has driven up the Hong Kong stock market and affected the performance of the A-share market. While ample liquidity is considered a key driver of market growth, high transaction costs remain a barrier to further market development.
The current lack of a robust market maker system in the Hong Kong stock market is one of the core reasons for insufficient liquidity. The absence of a market maker system leads to the following issues:
The introduction of a market maker system in Hong Kong can effectively address these issues. This system can provide stable liquidity, narrow bid-ask spreads, and reduce market volatility, thereby attracting more investors to participate.
The insufficient liquidity in the Hong Kong stock market partly stems from the impact of market structure and regulatory restrictions. These factors not only affect capital liquidity but also have a profound impact on investors’ trading behavior.
The market structure of the Hong Kong stock market is dominated by institutional investors, with relatively low participation from retail investors. This structure leads to high concentration in trading, causing imbalances in capital liquidity during certain periods. Additionally, the stock market in Hong Kong has a high concentration of stocks, with trading volumes of a few large companies dominating, further limiting the liquidity of small and medium-sized enterprises’ stocks.
Another challenge in market structure lies in the arrangement of trading hours. Compared to other international markets, the trading hours of the Hong Kong stock market are relatively short, which may restrict the efficiency of capital flow. Extending trading hours or introducing more flexible trading mechanisms could help improve this issue.
Regulatory policies have a dual impact on market liquidity. On one hand, strict regulations help maintain market stability and prevent excessive speculation; on the other hand, overly stringent regulations may suppress market activity and reduce capital liquidity. For example, the stamp duty policy in the Hong Kong market increases transaction costs, negatively affecting investors’ willingness to trade.
According to a study on Taiwan’s banking industry, regulatory policies have a significant impact on liquidity risk. The study analyzed the operational performance of 35 Taiwanese banks from 2015 to 2019, finding that increasing the liquidity coverage ratio had a significant negative impact on banks’ operational performance. The increase in capital adequacy ratios and non-performing loan ratios also had adverse effects. Here are the main findings of the study:
| Research Topic | Research Subject | Research Period | Main Findings |
|---|---|---|---|
| Impact of Liquidity Risk Regulatory Policies on the Operational Performance of Taiwanese Banks | 35 Taiwanese Banks | Q1 2015 to Q4 2019 | Increasing the liquidity coverage ratio has a significant negative impact on banks’ operational performance, with increases in capital adequacy ratios and non-performing loan ratios also having adverse effects. |
Although this study focuses on the banking industry, its findings are relevant to the Hong Kong stock market. Regulatory policies need to balance stability and liquidity to avoid suppressing market vitality due to excessive restrictions.
To address the challenges posed by market structure and regulatory restrictions, the Hong Kong market can consider the following strategies:
Through these measures, the Hong Kong stock market is expected to enhance liquidity and appeal while maintaining stability.

The core role of the Hong Kong market maker system is to provide stable market liquidity. Market makers, as liquidity providers, ensure that the market can facilitate buying and selling at any time by continuously quoting prices and executing trades. This stability is crucial for enhancing market efficiency, especially during periods of high volatility or low trading volume.
According to a report by China Securities, widely introducing a market maker system is expected to provide more liquidity to the market. The market maker mechanism introduced by the Hong Kong Stock Exchange for ETF products and dual-counter trading has already made positive contributions to enhancing market liquidity.
Moreover, market makers’ participation can improve the speed and certainty of trade execution, reducing delays caused by insufficient liquidity. This is significant for attracting more investors to participate in the Hong Kong stock market.
Another major advantage of the market maker system is narrowing bid-ask spreads. Bid-ask spreads are a key component of investors’ transaction costs, and excessively wide spreads can reduce investors’ willingness to trade, further impacting market liquidity. By continuously providing two-way quotes, market makers can effectively narrow bid-ask spreads, thereby reducing investors’ transaction costs.
For example, if the Hong Kong stock market can introduce a more robust market maker mechanism in the future, it will help address the liquidity shortages of certain stocks and further enhance the market’s appeal.
Excessive market volatility can negatively impact investor confidence and even lead to capital outflows. The Hong Kong market maker system can mitigate sharp market fluctuations by providing stable liquidity. During extreme market conditions, market makers can balance supply and demand by adjusting quotes and trading volumes, thereby reducing volatility.
The Hong Kong stock market has a high concentration of stocks, with trading volumes of a few large companies dominating. This structure can lead to imbalances during certain periods. Market makers’ participation can effectively alleviate this issue, providing a stable trading environment for the market.
Additionally, a stable market environment can boost investor confidence, attract more capital inflows, and create a virtuous cycle. This is significant for enhancing the international competitiveness of the Hong Kong stock market.
Investor confidence is a core driver of market liquidity. The liquidity shortage in the Hong Kong stock market is partly due to insufficient investor confidence. Enhancing investor confidence and participation requires efforts on multiple fronts, including improving market transparency, providing more investment tools, and establishing a stable trading environment.
Transparency is a key factor in attracting investors. The Hong Kong stock market needs to strengthen its information disclosure mechanisms to ensure investors have access to accurate and timely market information. The following measures can enhance transparency:
Increased transparency can reduce investor concerns, encouraging more capital to flow into the Hong Kong stock market.
Diverse investment tools can attract different types of investors to participate in the market. The Hong Kong stock market can consider introducing more innovative financial products, such as:
These tools can meet the needs of different investors, enhancing market appeal.
A stable trading environment is the cornerstone of boosting investor confidence. The Hong Kong market maker system plays a significant role in this regard. By continuously providing liquidity, narrowing bid-ask spreads, and reducing market volatility, market makers can effectively improve the trading environment. Specific measures include:
A stable trading environment can enhance investors’ sense of security, encouraging more capital to enter the market.
Market education is a long-term strategy to increase investor participation. Hong Kong can strengthen market education through the following methods:
Education can help investors better understand market operations and boost investment confidence.
Attracting international investors is a key way to enhance liquidity in the Hong Kong stock market. Hong Kong can adopt the following strategies to attract more international capital:
The participation of international investors can inject more liquidity into the Hong Kong stock market, creating a virtuous cycle.
The introduction of the Hong Kong market maker system not only stabilizes market liquidity but also enhances investor confidence and participation. This has profound significance for improving the overall competitiveness of the Hong Kong stock market.
The market maker system in the U.S. market is renowned for its efficiency and flexibility, providing an important reference for global financial markets. Market makers in the U.S. are primarily concentrated in NASDAQ and the New York Stock Exchange (NYSE), and the success of these markets is largely due to the active participation of market makers.
These measures not only improve market transparency but also attract more investors, further enhancing market liquidity.
The market maker system in the European market also demonstrates its advantages in improving market liquidity. For example, the London Stock Exchange (LSE) employs a multi-tiered market maker model to serve different types of investors.
The success of the European market shows that a robust market maker system can effectively enhance market efficiency and provide a more stable trading environment for investors.
The ETF market is a prime example of the application of the market maker system, offering valuable lessons for other markets. The role of market makers in the ETF market is reflected in the following aspects:
For example, the market maker mechanism introduced by the Hong Kong Stock Exchange for ETF products has made positive contributions to improving market liquidity. This demonstrates the significance of applying the market maker system to drive market development.
The experiences of international markets show that the market maker system has significant effects in enhancing market liquidity, stability, and appeal. These successful cases provide valuable references for the future development of the Hong Kong stock market.
The successful experiences of international markets offer valuable lessons for the Hong Kong stock market, particularly in the design and implementation of the market maker system. The following points are worth considering for the Hong Kong market:
Tip: According to NASDAQ’s experience, market maker participation can effectively narrow bid-ask spreads, reduce investor transaction costs, and improve market efficiency.
In summary, the successful cases of international markets demonstrate that a robust market maker system can enhance market liquidity and investor confidence. If the Hong Kong stock market can draw on these experiences, it is expected to achieve higher market efficiency and appeal.
Implementing the market maker system in Hong Kong poses significant challenges in terms of regulatory framework adaptability. The existing regulatory policies are primarily designed for traditional trading models, lacking clear guidelines for the roles and responsibilities of market makers. This may lead to concerns among market participants about the transparency and fairness of the system. Additionally, regulatory authorities need to balance market stability and liquidity to avoid excessive regulation stifling market vitality.
To address this issue, regulatory authorities should consider drawing on the successful experiences of international markets. For example, the market maker systems in the U.S. and European markets provide clear regulatory guidelines, ensuring market participants can follow unified rules. At the same time, Hong Kong could establish a dedicated regulatory department to oversee market maker operations and regularly evaluate the system’s effectiveness.
The acceptance of market participants directly affects the success of implementing the Hong Kong market maker system. Some investors may be unfamiliar with or even resistant to the new system’s operations. According to market surveys, quantitative data can quickly reflect participants’ attitudes, but qualitative interviews better reveal the underlying reasons. For instance, surveys show that some investors are concerned that market makers may manipulate market prices, while qualitative analysis indicates that this concern stems from doubts about the system’s transparency.
To improve acceptance, Hong Kong should strengthen market education to explain the operational principles and advantages of the market maker system to investors. Additionally, regulatory authorities could hold public consultation sessions to gather feedback from market participants and optimize the system accordingly.
Implementing the Hong Kong market maker system requires substantial capital and technical support. Market makers need strong financial capabilities to manage risks arising from market volatility. Meanwhile, advanced technical systems, such as automated quoting systems and risk management tools, are critical for achieving efficient trading.
Hong Kong can attract international financial institutions to participate as market makers to provide capital support. Additionally, the government and regulatory authorities should encourage local fintech companies to develop innovative technologies to enhance the market’s technical infrastructure. This will not only improve market makers’ operational efficiency but also strengthen the market’s international competitiveness.
To effectively address the challenges of implementing the market maker system in Hong Kong, policymakers need to adopt multifaceted strategies to ensure its successful rollout and enhance market liquidity. Here are some specific recommendations:
Regulatory authorities should develop specific regulations for market makers, clearly defining their roles, responsibilities, and rights. These regulations should include the following:
Tip: Drawing on NASDAQ’s regulatory model, Hong Kong could establish a dedicated department to oversee market maker operations and conduct regular reviews.
The government and regulatory authorities should provide necessary financial and technical support for market makers to reduce their operational costs and improve efficiency.
High transaction costs are one of the main barriers to market liquidity. Policymakers should consider the following measures:
Investors’ lack of understanding of the market maker system may affect its acceptance. Regulatory authorities should promote market education to enhance investors’ understanding and confidence in the system.
Note: Market education not only increases investor participation but also promotes the long-term stability of the market.
Hong Kong should further enhance the market’s internationalization to attract more foreign capital to participate as market makers.
These policy recommendations will help address the challenges of implementing the market maker system in Hong Kong and inject more liquidity and vitality into the stock market.

Reducing transaction costs is a key strategy for improving liquidity in the Hong Kong stock market. High transaction costs suppress investors’ willingness to trade, further weakening market activity. To address this issue, the Hong Kong stock market can consider the following measures:
According to MSCI Index data, the expected price-to-earnings ratios of U.S. and European markets show that the U.S. stock market’s expected P/E ratio has consistently been higher than Europe’s over the past five years. This phenomenon suggests that reducing transaction costs is closely linked to enhancing market appeal. When transaction costs decrease, market participation increases significantly, promoting liquidity growth.
A hybrid trading model combines the advantages of the market maker system and auction trading, effectively enhancing market efficiency. This model allows market makers to provide stable quotes during periods of low liquidity while retaining the flexibility of auction trading. Its main advantages include:
For example, the multi-tiered market maker model in the European market has successfully improved liquidity, providing valuable lessons for the Hong Kong stock market.
Expanding interconnectivity is an important strategy for attracting international capital. The Hong Kong stock market can strengthen ties with other markets through the following methods:
Deepening interconnectivity will inject more liquidity into the Hong Kong stock market and further enhance its international competitiveness.
Tip: Enhancing internationalization not only attracts more investors but also promotes the long-term stability of the market.
Improving market education and investor participation is a long-term strategy for enhancing liquidity in the Hong Kong stock market. Education can help investors better understand market operations, thereby increasing their willingness to trade and confidence. The Hong Kong market should adopt multi-tiered education methods, providing tailored learning resources for different investor groups.
Market education should combine online and offline resources to meet the needs of different investors. Here are some feasible measures:
Snapask’s success case shows that data-driven education methods can significantly improve learning efficiency. The platform analyzes usage data from seven types of students to provide real-time feedback to teachers, helping them adjust teaching methods. This approach not only enhances educational flexibility but also promotes personalized learning content. Similar data analysis techniques can be applied to investor education, providing targeted learning resources for investors with different experience levels.
Education and participation go hand in hand. Increasing investor participation requires creating a transparent and stable market environment. The following strategies can promote participation:
Enhancing investor education and participation will inject more vitality into the Hong Kong stock market, creating a virtuous cycle and further strengthening its international competitiveness.
The liquidity shortage in the Hong Kong stock market stems from multiple challenges, including low retail investor participation, high transaction costs, and market structure limitations. These factors collectively weaken the market’s activity and appeal. However, the market maker system plays a critical role in improving market liquidity. It can stabilize market liquidity, narrow bid-ask spreads, and enhance investor confidence.
Looking ahead, policy support and institutional innovation will be the core drivers of improving liquidity. For example, the share purchase actions by three major state-owned enterprises, such as Central Huijin, demonstrate the success of a “government guidance + market operation” model; share buybacks by multiple listed companies have injected confidence into the market. Additionally, the China National Financial Regulatory Administration’s increase in the allocation ratio for insurance funds in equity assets is expected to bring hundreds of billions of dollars in incremental capital to the market, supporting the development of emerging industries. These measures provide valuable references for the Hong Kong stock market.
With the further implementation of policies and the improvement of market mechanisms, the Hong Kong stock market is expected to achieve higher liquidity and international competitiveness.
The market maker system enhances market liquidity by continuously providing two-way bid-ask quotes, narrowing spreads, and stabilizing market volatility. This system attracts more investors to participate, promotes capital flow, and improves market efficiency.
Tip: Stable liquidity is crucial for attracting international investors.
Transaction costs in the Hong Kong stock market include commissions, stamp duties, and other fees. These costs are relatively high compared to other markets, directly affecting investors’ willingness to trade and further weakening market activity.
Suggestion: Reducing stamp duties and simplifying trading processes can alleviate investor burdens.
The Hong Kong stock market has limited appeal to retail investors due to high investment thresholds, costly transactions, and insufficient market information transparency. Addressing these issues will help increase retail investor participation.
The successful experiences of the U.S. and European markets show that a robust market maker system can enhance market liquidity, stability, and transparency. The Hong Kong stock market can draw on their multi-tiered models and innovative product designs to attract more international capital.
Example: The market maker mechanism in the ETF market has successfully improved liquidity.
The Hong Kong stock market can attract international investors by expanding interconnectivity, simplifying foreign investment processes, and reducing transaction costs. These measures will enhance the market’s international competitiveness and promote capital inflows.
Note: Increasing internationalization is critical for the long-term stability and development of the market.
