What are the wholly owned subsidiaries of the HKEX?

• A. SEHK; HKFE
• B. SEHK; HKFE; Associated clearing houses including Hong Kong Securities Clearing Company Ltd, The SEHK Options Clearing House Ltd, and the HKFE Clearing Corporation Ltd
• C. SEHK; HKFE; SEHK Options Clearing House Ltd
• D. SEHK; The HKEX Clearing Corporation Ltd

Answer: (B)

HKEX’s structure includes not only the two main exchanges but also the clearing facilities that support trading across markets. HKEX wholly owns the Stock Exchange of Hong Kong Limited and the Hong Kong Futures Exchange Limited, and it also wholly owns the associated clearing houses that underpin those markets: Hong Kong Securities Clearing Company Limited handles securities clearing, The SEHK Options Clearing House Limited clears options, and the HKFE Clearing Corporation Limited clears futures (and related products) on the HKFE. This full set—SEHK, HKFE, and the three clearing houses—is why the correct choice lists all of them. The other options omit one or more of these clearing entities, or refer to an entity that isn’t part of HKEX’s cleared-subsidiary structure.
