HKEX Proposes New Rules to Attract Middle East Listings, Boosting Hang Seng Index Internationalization

I. Introduction: HKEX's 'Middle East Chess Move' and a New Chapter for Hang Seng Index Internationalization

Amid the reshaping of global capital flows and the accelerated reorganization of geopolitical economic blocs, the Hong Kong Exchange (HKEX) is brewing a series of new listing rules targeting Middle Eastern companies. This move is seen as another key step by HKEX to internationalize the Hang Seng Index (HSI) and enhance market depth and resilience, following the Stock Connect mechanism, SPAC listing regime, and rules for specialist technology companies. As Middle Eastern sovereign wealth funds accelerate their deployment into Asia and countries like Saudi Arabia and the UAE advance their 'Vision 2030' economic transformation strategies, listings of Middle Eastern companies in Hong Kong will not only optimize the sectoral and geographical composition of the HSI but may also inject new liquidity into Hong Kong stocks. This article provides an in-depth analysis from multiple dimensions, including the content of the new rules, their potential impact on HSI composition, the interaction logic between Middle Eastern capital and enterprises, and the current geopolitical and liquidity challenges facing Hong Kong stocks.

II. Core of HKEX's New Rules: Lowering Barriers and Customized Arrangements

According to reports, HKEX is exploring mutual recognition frameworks with Middle Eastern regulators and major exchanges (such as the Saudi Exchange and Abu Dhabi Securities Exchange), proposing more flexible financial and governance requirements for Middle Eastern companies seeking listings. Specific measures may include: recognizing Middle Eastern accounting standards (such as localized versions of IFRS), simplifying the secondary listing process, and allowing weighted voting rights (WVR) structures. Additionally, HKEX may introduce a 'green channel' for Middle Eastern family-owned and state-owned enterprises to shorten approval times. The core intent of these institutional innovations is to reduce the implicit costs for Middle Eastern companies listing in Hong Kong, making it easier for them to be included in the Hang Seng Composite Index and even the Hang Seng Index constituents.

III. Optimizing Hang Seng Index Composition: From 'China-Dominated' to 'Global Diversification'

Currently, the Hang Seng Index's constituent stocks are heavily concentrated in mainland Chinese companies (including H-shares, red chips, and private Chinese enterprises), with technology, financial, and real estate sectors accounting for over 70%. The addition of Middle Eastern companies would bring two major structural changes: first, sector diversification—Middle Eastern companies focus on energy (oil and gas), petrochemicals, sovereign fund investments, infrastructure, logistics, and halal consumption, which can fill the HSI's gaps in traditional energy and commodities, reducing its over-reliance on tech stocks; second, geographical risk dispersion—Middle Eastern companies, as offshore issuers, have a low correlation with Asian assets, enhancing the HSI's appeal in global asset allocation. For example, if Saudi Aramco were to list in Hong Kong via a secondary listing, it would immediately become one of the largest energy giants by market cap in the HSI, fundamentally altering the index's sector weight distribution. Although initial listings may involve smaller companies, as the system matures, injecting Middle Eastern elements into HSI constituents is expected within three years.

IV. Attracting Middle Eastern Capital and Enterprises: The 'Dual Circulation' Effect of Sovereign Wealth Funds

Middle Eastern capital has been actively deploying into Asian markets in recent years: sovereign funds like the Abu Dhabi Investment Authority (ADIA), Qatar Investment Authority (QIA), and Saudi Public Investment Fund (PIF) have completed multiple investments in Chinese technology, new energy, and consumer sectors. HKEX's new rules not only attract enterprises but also activate the capital side. According to market sources, several Middle Eastern sovereign funds have expressed interest in participating in Hong Kong IPOs and secondary market allocations. After the new rules are implemented, Middle Eastern companies listing in Hong Kong will enjoy the convenience of 'immediate recognition by Middle Eastern capital,' as sovereign funds from the same region tend to favor familiar controlling entities in their investment decisions. This 'enterprise-capital' circular effect could create a positive feedback loop for Hong Kong stock liquidity: after raising funds in Hong Kong, some capital flows back to the Middle East for M&A, while the remainder stays in Hong Kong to invest in other stocks, thereby expanding the overall liquidity pool. Additionally, the allocation needs of Middle Eastern family offices and private banks will partially flow through HKEX's Stock Connect channels.

V. Geopolitical Economic Landscape and Hong Kong Stock Liquidity: Challenges and Opportunities

Hong Kong stocks are currently facing a liquidity contraction: since 2024, the average daily turnover of the HSI has dropped by about 30-40% from its 2020 peak, with foreign investor appetite for Chinese stocks dampened by geopolitical tensions and Sino-US regulatory disputes. Against this backdrop, introducing Middle Eastern companies can be seen as an alternative source of 'non-Western capital.' Middle Eastern countries pursue strategic autonomy, maintaining relative neutrality in crises like the Gulf crisis and the Russia-Ukraine conflict, and their capital preferences for Asian markets differ from those of the West. Listings of Middle Eastern companies could help Hong Kong stocks break free from the 'Western capital dominance' narrative, building a more resilient investor base. However, challenges are equally significant: differences in information disclosure transparency, corporate governance standards, and HKEX regulatory requirements need to be reconciled; the inherent volatility of Middle Eastern stock markets and geopolitical risks (such as oil price fluctuations and the Iran situation) could also spill over to Hong Kong stocks. Therefore, HKEX must carefully design a 'dual-track' regulatory framework to ensure investor protection is not compromised in the pursuit of attracting listings.

VI. Outlook: The 'Middle Eastern Pivot' for HSI Internationalization

If the new rules are successfully implemented, the weight of Middle Eastern companies in the Hang Seng Composite Index's total market cap could rise from near zero to 5-10% within three years, with the HSI potentially including 2-4 Middle Eastern issuers. This would not only be a historic breakthrough in HSI composition but also solidify Hong Kong's position as a 'super connector for China' and an 'Asian capital hub.' Amid the broader trend of global assets shifting eastward, Middle Eastern capital and enterprises will be a crucial pivot for the next phase of Hong Kong stock internationalization. Investors should closely monitor the progress of Saudi Aramco's secondary listing, the spin-off and listing of UAE's ADNOC businesses, and the IPO windows for PIF's tech investment platforms (such as Neom project-related companies). At the same time, it is essential to track the details of connectivity agreements between HKEX and the Saudi Exchange or Dubai Financial Market—these will determine the ultimate pace and scale of Middle Eastern companies listing in Hong Kong.
