Still hacking away at HFT

30 April 2012  |  2356 views  |  0

Had a distinct sense of déjà vu at TradeTech in London last week. Seems like much of the debate and chatter was the same as it was last year – HFT, ill thought through regulation, etc. It struck me, though, that maybe the regulators should let the market decide what is good or bad for us rather than agonising over these issues on our behalf. Take HFT for example. Whilst different definitions abound, electronic market making has just as much right to exist as any other business model in today’s trading ecosystem. If you don’t want to trade with them, then the answer’s simple – don’t!

A number of new dark pools are emerging that are specifically geared around allowing institutions to find natural liquidity between themselves. BLINK from Cheuvreux is just the latest example, and let’s not forget LiquidNet that pioneered the whole concept of buy-side crossing in the first place. For folks that don’t want to trade in size (such as the retail punters) then the narrower bid/offer spreads offered by electronic market makers look attractive. This has become the model adopted by MTFs such a TOM and Equiduct, powered by Optiver and Knight/Citadel, respectively.

Taken to its extreme then, you might end up with a separation of trading, with institutions placing more and more of their liquidity into broker dark pools and crossing networks whilst the retail community interacts with the HFT guys. But the real point is that, in any industry, market forces will always mean that different suppliers will shape their offerings in order to service distinct customer segments with similar needs. With this in mind, maybe the regulators should stop meddling and simply ensure that the depth, type and longevity of liquidity available at a venue is made clear to anyone that wishes to play there. The alternative is an endless array of corrections and counter-corrections from the regulators, just like a golfer having a really bad day on the course of unintended consequences.
