13-213MR ASIC makes rules on dark liquidity, high-frequency trading

Monday 12 August 2013


ASIC has released its market integrity rules on dark liquidity and high-frequency trading.

ASIC has also released guidance on the rules which clarifies ASIC’s expectations of market operators and participants.

‘The final rules follow extensive internal analysis and consultation with industry and will improve the transparency and integrity of crossing systems and strengthen the requirements for market participants to deter market manipulation,’ ASIC Commissioner Cathie Armour said.

‘We expect the new rules will quickly lead to changes in the behaviour of market participants, building on the positive changes we have already seen with other recent rule changes and the work of ASIC’s taskforces on dark liquidity and high frequency trading.

‘For example, there has been a significant decline in the volume of dark liquidity (below block size) as a result of the meaningful price improvement rule introduced in May this year, and we have observed a considerable drop in small and fleeting orders.’


Summary of rule changes


The rules will come into force in stages over nine months.
