Osaka Securities Exchange’s Matthias Rietig reports on the most recent developments in order routing and algorithmic trading in Japanese equities and derivatives.
Upgrades to Japanese Exchanges
Although the Japanese markets have been fully electronic since 1999, last year’s upgrade to arrowhead by the Tokyo Stock Exchange (TSE), as well as Osaka Securities Exchange (OSE)’s move to J-Gate, are quantum leaps in terms of performance. In OSE’s case, the move to faster technology - internal round trip times have been reduced from 60 milliseconds (ms) to below 1-2ms across all derivatives products - also paved the way for a broad revision of trading rules. All Japan-specific rules have been abolished, making way for global standard price/time First-In-First-Out based trading. This will make OSE more transparent and efficient, and hence, a fairer market.
Since Japan is one of the three largest equity markets in the world, the move towards a more globalized market structure, coupled with technology upgrades, will transform Japan into a new hot spot for High Frequency Trading (HFT). That being said, it is important for the exchanges to navigate through this paradigm shift wisely so as to not alienate the domestic user base and very active domestic retail participants. Although TSE volumes jumped about 10% after their move to arrowhead and spreads narrowed, the domestic proprietary trading houses that could not manage the very expensive transition as well as a huge decrease in profitability were driven out of the market, which resulted in a decrease of around 40% in the Japanese cash equity dealer population.
Although we see a proliferation of Multilateral Trading Facilities (MTFs / so called PTS’s in Japan), dark pools and crossing networks and the like entering the market, the liquidity from the domestic layers is still pretty sticky and has an exchange bias. That being said, even in Japan the times are changing and I expect the share of MTFs to increase steadily over time.
With the arrival of Chi-X Japan, all of the existing Proprietary Trading Systems (PTSs) reviewed their business models and it can be assumed that, due to the successful launch of arrowhead and a speed competitive main market, inter market arbitrage activity will rise. Since the Japanese exchanges are already very competitive with their pricing, the battle will be fought over value added services and features, like speed, tick sizes and access options. Overall, a decrease in trading fees can still be anticipated, which should benefit the end users.
While we do see the first signs of new growth of the PTS’s, overall volumes are still relatively small, with TSE capturing roughly 94% of the overall volumes on exchange equity cash trading, OSE about 5%, and the remaining PTS’s command a combined share of roughly 1%. It will be interesting to watch how market structure will evolve with the opening up of the JSCC, which for the first time started to serve PTS’s as a clearing house in July 2010.
Competition will increase, and although Japan is often labeled as overprotective, many domestic market participants believe it is a good development, as competition clearly cultivates services. The government, itself, is committed to induce more competition among markets to gain competitiveness in an international context and re-establish Tokyo as the financial focal point in Asia.
As the equity cash market is increasingly fragmented, the situation in the equity derivatives space is less so. OSE occupies the major chunk of Japanese equity index futures trading, the most prominent being the Japanese benchmark index Nikkei 225, through the Nikkei Mini Futures, which is one of the ten most actively traded index futures contracts, globally． Furthermore, OSE occupies a 100% share in Japanese Equity Index Options.
Although overall volumes went south for most of the other Japanese derivatives exchanges for the last couple of years, trading volume increased for five consecutive years. The newly launched J-Gate derivatives platform in Tokyo aims to make the overall market proposition of Japan more cost efficient and attractive. Located in the same data center as TSE as well as some PTS’s, J-Gate will hopefully benefit from cross connectivity, analogous to the US and European markets.
Smart order routing and algorithmic trading
Smart order routing (SOR) has been gaining traction in the last few years, and the launch of more sophisticated trading platforms, as well as the overall increase of sophistication of the buy-side, should further facilitate this trend. Although adoption by the international buy-side is already relatively widely implemented, the domestic layer has been more prudent to adopt SOR. In any case, it can be expected that the domestic players will catch up quickly, as they are currently screening the market to be ready once the overall liquidity on the PTS’s increases.
Compatibility
Order flow internalization and off-exchange crossing has been a common market practice in Japan for years. In 1998, Japanese regulators approved the introduction of the proprietary trading system (PTS), a privately operated night time marketplace. Then around 2005, we started to see PTSs operating during day time hours in direct competition with the traditional exchanges. In fact, PTSs are lit venues that operate similarly to the exchange. They have well defined market structure and market participants with price formation taking place in the visible order book. Most PTSs define their tick increments at about 1/10th that of the exchange. One major hurdle for PTSs is that they can not be more than 10% of the market share. Once they reach that point and hope to grow further, they will need to apply to become an exchange.
