Hong Kong Stock Connect New Regulations Implemented: ETF Inclusion Window Opens, Trading Threshold Significantly Lowered
On July 27, 2026, Hong Kong Exchanges and Clearing Limited (HKEX) and mainland securities regulatory authorities jointly issued an announcement, announcing two major new regulations to further optimize the Stock Connect mechanism between Mainland and Hong Kong stock markets (i.e., Hong Kong Stock Connect): starting from September 1, 2026, the scope of eligible ETFs under the Hong Kong Stock Connect will be broadly expanded, and the asset threshold for individual investors to participate in the Hong Kong Stock Connect will be lowered from RMB 500,000 to RMB 300,000. This adjustment is another major upgrade of the interconnection mechanism since the launch of Shanghai-Hong Kong Stock Connect in 2014 and the inclusion of ETFs in 2021.
HKEX Chief Executive Officer Chen Yiting said at a press conference: "The new regulations will further lower the threshold for mainland investors to participate in the Hong Kong stock market and provide them with more diversified investment options. We believe this will significantly enhance the liquidity and depth of the Hong Kong stock market and consolidate Hong Kong's status as an international financial center."
Historical Review of Hong Kong Stock Connect: From Single Stocks to Diversified Assets
Since the launch of Shanghai-Hong Kong Stock Connect in November 2014, the Hong Kong Stock Connect mechanism has been in operation for nearly 12 years. Initially, it only allowed mainland investors to buy and sell some eligible stocks under the Connect, with a trading threshold of RMB 500,000. In 2018, the Connect included companies with different voting rights (such as Xiaomi and Meituan), and in 2021, ETFs were added. As of June 2026, the cumulative net inflow of funds through the Connect has exceeded RMB 4.5 trillion, with average daily trading volume accounting for more than 20% of the total turnover of Hong Kong stocks.
However, with the growth of wealth among mainland residents and the diversification of asset allocation needs, the original mechanism has gradually revealed two major bottlenecks: first, the number of eligible ETFs was limited (only 81 as of early July 2026) and concentrated on large-cap indices; second, the 500,000 yuan threshold excluded many middle-class investors. These new regulations are precisely targeted at these pain points.
Key Highlights of the New Regulations: ETF Expansion and Threshold Reduction
Number of Eligible ETFs Expected to Double, Covering Small and Mid-Cap and Thematic Indices
According to HKEX announcement, starting from September 1, 2026, the Hong Kong Stock Connect will add approximately 120 new ETFs, bringing the total number of eligible ETFs to over 200. The new additions will cover Hong Kong stock small and mid-cap indices (such as the Hang Seng Composite SmallCap Index), industry thematic indices (such as biotechnology, new energy, artificial intelligence), and some leveraged/inverse products (subject to investor suitability restrictions). Mainland investors will be able to directly trade ETFs tracking Asian markets such as South Korea and Vietnam through the Connect, enabling "overseas" investment.
Access Threshold Lowered to RMB 300,000: Unleashes Nearly 200 Million Potential Investors
The asset requirement for individual investors has been reduced from RMB 500,000 to RMB 300,000, the first reduction since 2014. According to data from China Securities Depository and Clearing Corporation, as of June 2026, there were approximately 120 million individual investors in China meeting the RMB 300,000 asset condition, an increase of about 58% compared to 76 million who met the RMB 500,000 threshold. This means that over 40 million new investors will gain access to the Hong Kong Stock Connect. Market participants expect that the average daily net inflow of southbound funds will increase from the current RMB 8 billion to over RMB 12 billion in the short term.
Trading Mechanism Optimization: Removal of Minimum Commission Limit, Pilot T+0 Round-Trip Trading
In addition to the threshold and target adjustments, HKEX also announced that from October 2026, Hong Kong Stock Connect investors will no longer be subject to the minimum commission rule (currently 0.25% of transaction amount), and securities firms can set their own commission rates. At the same time, a "T+0" round-trip trading (buy and sell on the same day) pilot will be launched for some ETFs with sufficient liquidity, further aligning with international practices.
Industry Interpretation: Advantages of Hong Kong Stock Investment Further Highlighted
The Hong Kong market is known for its internationalization, professionalism, and high dividends. In the first half of 2026, the dividend yield of the Hang Seng Index was approximately 3.8%, higher than the Shanghai Composite Index's 2.1%. Among companies listed on HKEX, more than 70% come from mainland China, but their valuations are generally lower than those of A-shares: the Hang Seng AH Premium Index closed at 145 points on July 27, indicating that the price of the same company in Hong Kong stocks is on average 31% lower than in A-shares.
"After the threshold reduction of the Hong Kong Stock Connect, mainland investors can more flexibly capture AH spread opportunities, especially for leading stocks in traditional industries such as finance and energy, where the arbitrage space is significant," noted a strategy analyst at a foreign investment bank. In addition, the Hong Kong stock market has many globally scarce targets, such as REITs offering high dividend yields and globally leading tech unicorns (for example, ByteDance's Hong Kong listing time is not yet determined, but ETFs linked to its ADRs can be traded).
Practical Guide for Investors: How to Seize New Opportunities
- Account Opening and Qualification Verification: Mainland investors must still open Hong Kong Stock Connect permissions through mainland securities firms. After the new regulations, investors with assets between RMB 300,000 and RMB 500,000 can apply immediately without waiting. Identity verification and knowledge assessment have been fully online, with an average processing time of 2 hours.
- ETF Selection Strategy: It is recommended to focus on newly added small and mid-cap index ETFs and thematic ETFs. For example, there are already several ETFs tracking the Hang Seng Tech Index, but the newly added biotechnology index ETF (such as the "Hang Seng Healthcare ETF") can target the innovative drug track; new energy thematic ETFs cover the photovoltaic, electric vehicle and other industry chains.
- Note Differences in Trading Rules: Hong Kong stocks have no price limit restrictions and allow short selling. Meanwhile, the settlement cycle is T+2, different from A-shares' T+1. After the reform, some ETFs pilot T+0, but investors still need to be familiar with various rules.
- Exchange Rate Risk: The Hong Kong Stock Connect is priced in RMB, but actual transactions are settled in Hong Kong dollars, with final gains or losses affected by the RMB-HKD exchange rate. It is recommended that investors properly allocate hedging tools or choose ETFs that track the RMB exchange rate.
Market Outlook: Southbound Fund Structure May Be Reshaped
As more small and medium-sized investors enter the market, the investment style of southbound funds may shift from "institution-dominated" to "both retail and institutional". Historically, Hong Kong Stock Connect funds favored large-cap tech stocks such as Tencent and Meituan, and financial stocks such as HSBC and China Construction Bank. After the new regulations, small and mid-cap stocks and thematic ETFs may receive more attention, thereby boosting valuations in some sub-sectors.
The latest data from HKEX shows that on July 27, net purchases of southbound funds reached RMB 14.5 billion, a new single-day high this year, with the proportion of ETF net purchases jumping from 8% previously to 35%. The market generally expects that in the next three months, the number of new investors opening Hong Kong Stock Connect accounts will exceed 1.5 million.
Conclusion
The new Hong Kong Stock Connect regulations will be implemented in batches starting from September 1, 2026. Mainland investors should prepare knowledge and capital plans in advance. Whether pursuing AH spread arbitrage, capturing globally scarce targets, or achieving regional diversification through ETFs, the Hong Kong market is welcoming mainland capital with an unprecedented openness. For investors looking to expand their overseas investment horizons, 2026 is undoubtedly one of the best times to "bottom fish" Hong Kong stocks.
