Market Turnover


Hong Kong Exchanges and Clearing Limited and its affiliated companies (together "HKEX", "we", our” or "us") are committed to protecting all Personal Data under our custody, control, or possession. “Personal Data” is any information that relates to an identifiable individual or can be used to identify an individual – sometimes the individual is referred to as a “Data Subject” or consumer .

HKEX is Hong Kong based and therefore, when using our Website, any Personal Data collected through online forms or cookies will be transferred to Hong Kong even if you are located in another jurisdiction.

This privacy notice (“Notice”) applies to the Personal Data we collect and generate from Data Subjects who access our various websites as indicated in the table below:



HKEX Market

As we also provide links to the websites of independent third parties, we encourage you to read the privacy policies on these other websites as we cannot control nor are we responsible for how they handle your Personal Data.

This Notice sets out what Personal Data we process, how we process it, who it might be transferred to, how we protect it, and rights under the applicable data protection laws. We will revise this Notice from time to time to reflect any relevant developments at HKEX relating to our business or operations or in the services delivered through our Website, or due to changes in the applicable laws and regulations.

To the extent required under applicable data protection laws, we will notify Data Subjects of the material changes and, where required, seek their consent.

If the correct Personal Data is not submitted to HKEX then access to certain products and services through the Website cannot be provided and we may also be unable to process requests from the Data Subjects relating to their rights under the applicable data protection laws. HKEX is also required to perform certain regulatory functions which may not be possible if we are not provided with the requested Personal Data.

What Personal Data do we collect and how do we collect it?

Sensitive Personal Data

Some Personal Data that we process is classified as “Sensitive Personal Data” under applicable data protection laws.  What is considered Sensitive Personal Data varies by jurisdiction. If we are required to process Sensitive Personal Data, we will only do so in accordance with applicable law, and with your consent to the extent required under applicable data protection laws.       

Our processing of Sensitive Personal Data in certain jurisdictions for the purposes of this Website requires specific disclosure:

Why do we use the Personal Data and how do we use it?

The “Legal Basis” is what data protection laws set out as the lawful reasons for processing Personal Data, such as a legitimate interest to operate our business so long as it does not materially and adversely impact your interests, rights, and freedoms.

Direct Marketing

Before we share Marketing Data within HKEX group (including HKEX group members covered under this Notice) in order to send direct marketing and promotional and informational content relating to our financial products and services (“Marketing Communications”), we may need to first ask for permission by obtaining the Data Subject’s explicit opt in or indication of no objection as required or permitted under the applicable data protection laws. 

To provide our Marketing Communications, we will usually use the name, job title, phone number, email address and contact preferences and, occasionally, we may also make use of the marketing profiles generated from the use of our Website, cookies and similar tracking technologies combined with information directly obtained from the Data Subject and other sources (‘Marketing Data’).

At any time, the Data Subject can opt out or change their marketing preferences in terms of the frequency, delivery channel, and category or type of Marketing Communication – this right exists even if we are not required to obtain consent for the sending of Marketing Communications.  To action this right, the Data Subject can provide their full name, email address, log in name (if applicable) and details of the product and/or service to which they have subscribed to the address in the “Contact Us” section below. We will provide a reminder of this right in each of our Marketing Communications.

Please note that even if an opt-out request has been made, we may still need to send necessary communications such as those relating to the administration of a subscription. In addition, it does not impact the lawfulness of our use of the Personal Data prior to the consent being withdrawn.

Cookies and similar technologies are used in the Marketing Communications to analyse engagement and effectiveness. The specific tools that enable this will track and record clicks and hovers, searches, and distinguish between known and unknown users. For further details on how we adopt cookies and other similar technologies, please refer to our Cookies Policy. 

Occasionally, we will engage third party service providers to support our marketing initiatives and enabling members of the HKEX group to send Marketing Communications. Where required under applicable data protection laws, HKEX shall obtain the Data Subject’s prior consent. Where third party platforms are utilised, we also recommend that you refer to their privacy statements.

Do we disclose Personal Data to third parties or transfer it to another jurisdiction?

HKEX sometimes discloses Personal Data to third party organisations and partners that enable our exchanges and clearing business, so that we can operate this Website, provide you with products and services, improve our offerings, or comply with applicable laws.  These third party Personal Data recipients and specific transfer purposes are set out below:

  • Affiliates of Hong Kong Exchanges and Clearing Limited
  • Organisations involved in hosting or organising activities for us

Where required under applicable data protection laws, HKEX will only disclose Personal Data to third parties with your prior consent. In certain jurisdictions, HKEX may also be required to take additional measures prior to giving effect to such transfers (e.g. carrying out privacy impact assessments prior to the transfer).    

HKEX may process Personal Data outside of the Data Subject’s home jurisdiction, including sharing the Personal Data with third parties (such as suppliers). HKEX shall use reasonable endeavours to ensure that the laws and regulations of the destination jurisdiction shall offer the same or comparable level of protection for Personal Data. Where this is not the case, we shall ensure appropriate safeguards are in place at the time of the transfer by implementing standard contractual clauses or other data transfer mechanism approved by the authorities of the relevant jurisdiction.  Where required under applicable data protection laws, we shall also carry out additional measures for the offshore transfer such as carrying out a privacy impact assessment.

The regions where the Personal Data may be hosted or transferred to will vary from time to time, but typically include Hong Kong, the UK, US, EU, Switzerland, Singapore, Japan, India, and Mainland China.
