Hong Kong Exchanges and Clearing Limited (HKEX) has announced a regulatory approval for rule amendments, set to take effect from July 27, 2026.

The modifications focus on two primary areas: enhancing the strike price intervals and associated market maker arrangements for weekly stock index options, which cover the weekly Hang Seng Index (HSI) options, weekly Hang Seng China Enterprises Index (HSCEI) options, and weekly Hang Seng Tech Index (HSTECH) options.

The second change involves renaming the "Hang Seng China H-Financials Index" futures contract to the "Hang Seng Stock Connect China Financials Index" futures contract, aligning it with the underlying index's new name.

These updates are detailed in the revised contract specifications for the weekly HSI options, weekly HSCEI options, and weekly HSTECH options.
