Hong Kong Exchanges and Clearing Limited (HKEX; ) manages markets for equities, commodities, fixed income, and currencies through its subsidiaries: The Stock Exchange of Hong Kong Limited (SEHK), Hong Kong Futures Exchange Limited (HKFE), and London Metal Exchange (LME).

By December 2024, HKEX’s market capitalization reached around US$35 trillion, hosting 2,631 listed companies, positioning it as the world's eighth-largest stock exchange. It also ranked tenth globally in terms of IPO proceeds during the first quarter of 2024.

In Hong Kong, HKEX operates four clearing entities: Hong Kong Securities Clearing Company Limited (HKSCC), HKFE Clearing Corporation Limited (HKCC), SEHK Options Clearing House Limited (SEOCH), and OTC Clearing Hong Kong Limited (OTC Clear). HKSCC, HKCC, and SEOCH provide comprehensive clearing, settlement, custody, and nominee services. OTC Clear specializes in clearing and settling OTC interest rate derivatives and non-deliverable forwards. Market data distribution is handled by HKEX Information Services Limited.

The largest shareholder of HKEX is the Hong Kong Government, which holds the authority to appoint six out of thirteen board members.

Securities market

The origins of securities trading in Hong Kong trace back to the mid-1800s. The initial formal marketplace, known as the Association of Stockbrokers in Hong Kong, was founded in 1891 and later renamed the Hong Kong Stock Exchange in 1914.

Another exchange named the Hong Kong Stockbrokers' Association was established in 1921. These two entities merged in 1947 to revive the stock market after World War II. Economic expansion led to the creation of three additional exchanges: Far East Exchange (1969), Kam Ngan Stock Exchange (1971), and Kowloon Stock Exchange (1972).

To consolidate and regulate these various markets, the Stock Exchange of Hong Kong Limited (SEHK) was formed in 1980. The four separate exchanges ceased operations on 27 March 1986, with SEHK launching an automated trading platform on 2 April 1986. Before its merger with HKFE in March 2000, the combined exchange had 570 participant firms.

The Hong Kong Securities Clearing Company Limited was set up in 1989 to introduce CCASS—the centralized clearing and settlement system—which began functioning in 1992 and became the central counterparty for all market participants.

Penny stocks fiasco

In April 2002, HKEX introduced a proposal to delist penny stocks aiming to enhance market efficiency. The July 2002 initiative targeted companies whose share prices remained below HK$0.50 for thirty consecutive days. This led to a significant drop in share prices for seventeen firms and resulted in about HK$6 billion being wiped from the market capitalization across 105 listings.

Investor activist David Webb criticized HKEX for acting both as market operator and regulator, emphasizing that these companies generated minimal revenue relative to their regulatory costs. He advocated transferring regulatory oversight to the Securities and Futures Commission (SFC).

A government report published on 10 September 2002 attributed administrative lapses concerning the preparation and publication of the consultation paper to HKEX Chief Executive Kwong Ki-chi.

Base metals market

In June 2012, HKEX revealed a cash bid to purchase the London Metal Exchange (LME), the foremost global metal exchange since 1877, for GBP1.388 billion. This acquisition was finalized by December 2012.

HKEX also holds a majority stake in the Qianhai Mercantile Exchange, a commodities trading platform based in mainland China that has yet to commence operations. Although the Qianhai Authority granted permission for HKEX to set up this platform within the special economic zone, regulatory restrictions on spot trading in mainland China have postponed its launch.

Merger speculation

After the New York Stock Exchange announced plans in 2006 to establish a Beijing office and partner with the Shanghai Stock Exchange, HKEX chairman Ronald Arculli indicated no immediate intentions for mergers or acquisitions, prioritizing competitiveness improvements and a review of listing fees instead.

In September 2019, HKEX put forward a £29.6 billion cash and share merger proposal with the London Stock Exchange, valuing the transaction at £31.6 billion ($39 billion) including debt. Had this merger been successful, the combined organization would have become the third largest exchange globally by market capitalization, following NYSE and NASDAQ.

Infrastructure

HKEX upgraded its trading infrastructure by adopting computerized systems on 2 April 1986. It introduced the "Automatic Order Matching and Execution System" (AMS) in 1993, which was further enhanced to AMS/3 in October 2000 to support increasing online trading volumes.

Trading hours

The trading schedule at HKEX consists of a morning session from 09:00 am to 12:00 pm, an extended morning session until 1:00 pm, followed by an afternoon session from 1:00 pm to 4:00 pm.

The Closing Auction Session (CAS) was rolled out in two stages on 25 July 2016 and 24 July 2017. Eligible securities include all stocks within the Hang Seng Composite LargeCap, MidCap, and SmallCap indices; H shares linked with mainland A shares; all exchange-traded funds (ETFs); and selected regulated short-selling orders.

To control market fluctuations, a Volatility Control Mechanism (VCM), akin to circuit breakers used in the US markets, was implemented in two phases on 22 August 2016 and 16 January 2017.

Products

HKEX provides an extensive portfolio of securities products such as equity securities, depositary receipts, debt instruments, unit trusts/mutual funds (including ETFs and REITs), as well as structured products. Its derivatives offerings include index and stock futures and options, interest rate and fixed income instruments, alongside gold futures.

Controversies

Government equity acquisition

In September 2007, the government boosted its ownership in HKEX from 4.41% to 5.88%, investing HK$2.44 billion to purchase 15.72 million shares from the Exchange Fund as a "strategic asset." This action drew criticism both locally and internationally. Governance expert David Webb pointed out that the government became the second-largest individual investor in Hong Kong's stock market, with local equities worth approximately HK$150 billion, arguing that this contradicted the "big market, small government" philosophy and introduced uncertainty into the market.

The Civic Party accused the administration of damaging public trust and meddling with the exchange's autonomy. A Wall Street Journal editorial condemned the acquisition as governmental interference intended to align with China's state-controlled domestic exchanges. Financial analyst Jake van der Kamp observed a conflict of interest for the government between fostering an efficient marketplace and pursuing shareholder value.

The government defended its position as a constructive shareholder promoting HKEX's growth. Market analysts expect further increases in government shareholding as HKEX moves toward integration and partnerships with mainland Chinese exchanges. Questions were also raised about chairman Ronald Arculli’s independence given his simultaneous membership on Hong Kong’s Executive Council.

Extension of directors’ trading blackout regulation

From January to April 2008, HKEX put forward amendments to the Listing Rules covering 18 aspects of corporate governance and listing standards. On 28 November 2008, new regulations were unveiled, including prolonging directors’ trading blackout periods from the semester’s end until after financial results are released. These revisions became effective on 1 January 2009. Previously, the blackout lasted one month before results publication, which HKEX considered inadequate to curb insider trading involving unpublished sensitive information.

In December 2008, legislators representing functional constituencies—led by Abraham Razack, Chim Pui Chung, and David Li—called on regulators to delay the extended blackout implementation. Razack criticized the consultation process as opaque and lacking widespread industry engagement, while David Webb attributed resistance to powerful tycoons and directors opposing tighter restrictions. On 30 December, despite these objections, the Listing Committee confirmed the rule’s adoption for its long-term market advantages but postponed enforcement by three months.

Allegations of CEO's Role in "Princeling" Recruitment

In 2015, the Wall Street Journal revealed that former CEO Charles Li Xiaojia, during his tenure as chairman of JP Morgan China from 2003 to 2009, was involved in advocating for the employment of offspring and associates connected to Chinese officials and clients. This practice prompted investigations by the US Securities and Exchange Commission and US Department of Justice into possible breaches of anti-bribery laws linked to these "princeling" appointments, which were allegedly intended to facilitate business opportunities.
