HKEX to Enhance Strike Price Intervals for Weekly Options

On 25 June 2026, HKEX announced plans to narrow strike price intervals for weekly stock and index options, to take effect on 27 July 2026 subject to regulatory approval. Tighter strike ranges will only apply to weekly options while monthly options remain unchanged, and HKEX will increase market maker responsibilities to boost liquidity. The change provides more strike prices near market levels for precise short-term trading, improving price discovery and trading turnover. Launched in November 2024, weekly stock options are HKEX’s fastest-growing derivatives; 17 new contracts added in June bring the total to 33, alongside weekly options for the Hang Seng Index, Hang Seng China Enterprises Index and Hang Seng TECH Index to help investors hedge short-term risks. Full revised strike price rules and operational details are specified in circulars released by SEHK and HKFE.
