The Singapore Exchange is consulting the market on plans to slash its minimum order size for securities trading, which it says will encourage greater trading in blue chips but will not lead to a rise in high-frequency trading.

Trades in Singaporean equities and other securities such as warrants and trusts must be a minimum of 1,000 units, with any outstanding volume traded on a specially-designated 'unit share market' that trades orders between one and 999 units.
