PTSs shouldn’t celebrate too soon

While alternative venues in Japan are claiming a victory with the relaxing of a key rule which was restricting their growth, there are still many more obstacles in their path, warns Hiroshi Matsubara, marketing director of trading technology firm Fidessa’s Tokyo office.

Last week, the Japanese Financial Services Agency (FSA) drafted revisions to the Financial Instruments and Exchange Law, which forces investors that approach a 5% stake in any firm to launch a tender offer. Such a rule has made it difficult for some participants to trade easily on proprietary trading systems (PTSs) for fear of accidentally breaching the rule.

“This was very exciting news for the electronic trading community in Japan,” says Matsubara, explaining the 5% ‘tender offer bid’ (TOB) rule itself was not abolished as such, but PTS trading will become exempt from its application.

Matsubara agrees with market consensus that the rule change will boost the development of PTS trading in a market undergoing a period of rapid change. A merger between the Tokyo Stock Exchange (TSE) and the Osaka Securities Exchange (OSE) was announced 22 November and is currently slated for January 2013. PTSs are trying to build market share and define themselves in this changing environment.

“A lot of domestic buy-side trading desks currently either don’t trade on PTSs or only trade sell orders, mainly because of the 5% TOB restriction,” Matsubara says. “If this change becomes effective from October as planned, I would personally project the PTS trading share – which currently hovers around 6% – will reach 10% or beyond by summer next year.”

In June, the two major PTSs lost some of their recent gains, dropping to a collective 5.29% market share from 5.89% a month earlier. SBI Japannext’s market share increased to 3.62% from 3.43%, while Chi-X Japan’s fell to 1.67% from 2.46%. The TSE regained a sliver of market share, claiming 90.48% – up from 89.86% in May.

Matsubara believes high frequency trading (HFT) firms are also excited about the regulatory relief and are perched to inject more liquidity into PTSs.

“From a market-making perspective, more trading participation will mean more market takers flowing in. Therefore, market-making HFTs will be ready to more aggressively market-make in PTSs,” says Matsubara. “This will lead to more trading values on PTSs.”

Size matters 

Noting PTSs’ small average trading size in comparison with the TSE, Matsubara sees a question mark over how well they can effectively handle the relatively larger-sized orders which typically come from Japan’s domestic buy-side firms.

And Matsubara identifies margin trading as another restriction on the alternate venues.

“PTSs claim that a lack of margin trading is blocking more order flows by individual investors,” he says. “This may be true, but I’m not sure if private investors are ready to take a benefit of PTSs yet.”

The TOB relaxation is the second favourable rule change for PTSs this year. In April, the regulator decreased the circumstances in which it would halt the trading of securities on PTSs following market backlash over its handling of a technology glitch that halted trading for nearly four hours on the TSE.

But Matsubara thinks the next big hurdle for PTS development will be Japan’s 10% trading share restriction, which requires venues to get an exchange licence if they trade more than 10% of national volumes.

“It may take a bit more time for PTSs to reach this mark, but this will be the big challenge for PTSs and it remains to be seen if the FSA would be ready to relax this restriction,” says Matsubara. “An exchange licence would be a big cost for a PTSs, and as soon as it became an exchange, a PTS would have no instruments to trade, because Japanese exchanges are only permitted to trade instruments listed on their own exchange!”

Matsubara thinks the restriction should be relaxed somehow, either by changing the ceiling limit or changing the rule of exchange itself, which was the experience in the US. But in any case, while the lifting of the 5% TOB restriction was good news, the coast is not yet clear for rapid PTS expansion.
