Proposed amendments to the Securities & Futures (Contracts Limits & Reportable Positions) 2007 Rules have been gazetted.

The Securities & Futures Commission said the amendments will adjust the prescribed limits for H-shares index futures and options contracts from 6,000 contracts per futures contract month or options contracts series, to an aggregate delta limit of 12,000 applicable to all futures contract months and options series.

Subject to the Legislative Council's vetting, the new limit will take effect March 30.

Commission Chief Executive Officer Martin Wheatley said: "The adjustment will help maintain Hong Kong's leading position in the face of competition from the other exchanges which are keen to develop derivative products on Mainland related equities."

The proposed adjustment will better meet the market's needs and promote the growth of the futures and options markets, he added.

The commission is reviewing the positions limit of HSI futures and options contracts, and will consult market participants in next few months.
