HKEX To Enhance Strike Price Intervals For Weekly Options

Hong Kong Exchanges and Clearing Limited (HKEX) is pleased to announce today (Thursday) enhancements to the strike price intervals of both weekly stock and index options, with implementation scheduled for 27 July 2026, subject to regulatory approval.

The enhancements will introduce narrower strike price intervals for weekly options, increasing the number of available strike prices around the prevailing market level.

By enabling more precise positioning, the new framework will facilitate more efficient trading and price discovery in weekly options. This will help bolster liquidity and overall trading activity, as market participants make greater use of short-dated options strategies.

Under the new arrangement, the enhanced intervals will apply to weekly expiries, while the existing strike price interval arrangements will continue to apply to monthly stock and index options. HKEX will also expand market maker obligations to support market liquidity.

Weekly stock options have emerged as one of HKEX’s fastest-growing derivatives products since their launch in November 2024. Following the introduction of 17 new weekly stock options in June, HKEX has expanded its range in this short-dated category to a total of 33 contracts, providing investors with a broader set of tools to manage short-term market risks. HKEX also offers weekly options on the Hang Seng Index, Hang Seng China Enterprises Index and Hang Seng TECH Index.

Detailed arrangements, including the revised strike price intervals and related operational details, are set out in the relevant circulars issued by The Stock Exchange of Hong Kong Limited (SEHK) and Hong Kong Futures Exchange Limited (HKFE).
