HKEX plans to launch zero-day options on Hang Seng Index in early 2027: Bloomberg

Hong Kong Exchanges and Clearing (0388) is aiming to introduce same-day expiration options contracts in 2027, Bloomberg News reported, citing sources. 

HKEX is planning to launch “zero-day to expiry” contracts on the Hang Seng Index in the first quarter of next year, the news agency said.

Bloomberg reported last year that the bourse was aiming to launch the derivatives as soon as this year, and that the exchange had consulted with market participants and received positive feedback on the proposal. 

This financial instrument has fueled the rapid growth of the US derivatives market in recent years, the report said.

The 0DTE contracts were first introduced in the US in 2022, and by the fourth quarter of 2024, they accounted for over half of all S&P 500 index options trading volume, Bloomberg said.
