Rather than solving the puzzle, the proliferation of venues has had a very different consequence— namely of greater liquidity frag- mentation, says Kumaresan. As yet there remains no single universal trading protocol that suits all the different types of fixed income order sizes and names. Each venue is currently attempting to solve the order matching prob- lem differently with an emphasis on different segments of the liquid- ity and size spectrum. “While the classical RFQ (re- quest-for-quote) trading protocol, used by MarketAxess, is good for somewhat smaller orders and for the more liquid end of the universe it is not suitable for very large orders or illiquid names, because the information leakage is too high with this approach,” says Kumare- san. “The Liquidnet and Trumid pro- tocols, on the other hand, leak less information but finding a match manually is more difficult. If a pro- tocol is stealthy, then by definition, the low information leakage will also reduce the chances of spotting that liquidity. The key to solving the liquidity puzzle is to embrace all useful trading venues and protocols through a smart liquidity seeking algorithm.” There is, of course, the argument that buy-side trades are too cor- related to enable the all-to-all mar- ket to work, because how do you find a seller when everyone else wants to buy too? But Kumaresan disputes the correlation argument. “While there is a fair level of correlation, the mere fact that sell- side market makers typically turn over most of their books within five days implies that there is sufficient interest on the opposite side of a trade within this small time win- dow,” he says. “Given that the buy- side has 95% plus of the liquidity, we are most likely the ones on the opposite side too, helping turn over sell-side books. This would imply that we are not as correlated as we may think.” Clearly there is still much work to do in order to meet the demand for a new class of technology that can aggregate the vast quantities of data in the fixed income market, while also enhancing workflows in a seamless manner and intro- ducing a smart liquidity-seeking algorithm. While that is no small task to take on, the pace of technology innovation has undoubtedly spiked in recent years, meaning traders can often be spoilt for choice when it comes to selecting systems – albeit with the caveat that while good systems, they do not provide a seamless workflow. As Kumaresan puts it: “Empowering traders with technology tools is how one gets an edge. It’s like hunting; even if you are a great hunter you still need the tools to get the job done.”
