Hong Kong Exchanges and Clearing (HKG:0388) will increase the holding ceilings for futures and derivatives based on the city's three major indices starting July 2, the bourse operator said in a circular Friday.

The bourse will increase the position limit for the Hang Seng Index to 15,000 position delta from 10,000 position delta. It will also raise the limit for the Hang Seng China Enterprises Index to 25,000 position delta from 12,000 position delta, and the Hang Seng TECH Index to 30,000 position delta from 21,000 position delta.

HKEX's increases are part of proposed changes to statutory position limits for the Hang Seng Indexes derivatives set by the Securities and Futures Commission in April, the bourse said.
