Hong Kong Bourse Plans to Start Zero-Day Options in 2026

Hong Kong’s stock exchange is seeking to launch options that expire within a day as early as the first half of 2026, bringing to the Asian hub an instrument that has driven a boom in US derivatives in recent years.

Hong Kong Exchanges & Clearing Ltd. is planning to start offering “zero-days to expiry” contracts on the Hang Seng Index, according to people familiar with the matter who asked not to be named because the matter is private. The bourse has been consulting with market participants and the feedback has been positive, they added.
