Which entity enforces HKEx listing, trading, clearing, and settlement rules?

• A. HKEx
• B. SFC
• C. HKMA
• D. Insurance Agent Registration Board

Answer: (A)

The entity that enforces HKEx’s own rules is the exchange itself. HKEx operates the market and has its own market regulation and disciplinary processes to ensure compliance with its Listing Rules, Trading Rules, and Clearing and Settlement Rules. It can investigate breaches by listed issuers, brokers, and other participants and impose sanctions such as fines, suspensions, or delistings to maintain market integrity. The SFC, by contrast, enforces securities laws under the Securities and Futures Ordinance and can take actions for broader market misconduct, but the day-to-day enforcement of HKEx’s specific rules rests with HKEx’s own enforcement framework. The HKMA oversees banks and payment and settlement systems, not HKEx rule enforcement, and the Insurance Agent Registration Board is not involved in the securities market.
