When the NSE shut down for four hours on February 24, that was supposed to be the BSE’s moment in the sun. However, volume did not move as much to the BSE on that day. Instinctively or by force of habit, people trade on the NSE since it is more liquid and impact cost is lower, and a lot of large players decided to back off till there was clarity. For BSE, which has been trying hard to increase its trading volume, this response to NSE’s shutdown must have added insult to injury, especially since it has not had the glitches NSE has seen over the years.
BSE CFO Nayan Mehta says their system has suffered no glitches or errors since 2010 as compared to NSE, which has suffered about 10 glitches since 2015. BSE can process 500,000 orders per second, using the Deutsche Börse trading system but will its glitch free track record hold up when volume picks up? NSE handles a much higher load as of now, as it hogs almost the entire volume in derivatives as well as the cash market.
We are still in the dark about what exactly caused the NSE glitch. In its initial disclosure, NSE had mentioned that trading was halted due to “issues with the links with telecom service providers.” The exchange’s spokesperson declined to share the timeline given by Sebi to submit the root cause analysis report. Even Sebi did not respond to the questions sent.
On whether communication during the shutdown could have been better on part of NSE, the spokesperson repeated the same defence stated in an earlier press release: “NSE was continuously working on resolution of the problem and once the same was resolved, NSE made an announcement with respect to re-opening of the markets to its members at 3:17 PM. This communication was done only after there was visibility and clarity on resumption of services and any prior communication would not have been appropriate.”
This lack of communication has certainly cost brokers and their clients. With brokers clueless until the last-minute announcement, many including Zerodha Broking squared off intra-day equity positions on the BSE around 3:10 PM on that day, as a risk mitigation measure. Their clients clearly weren’t happy given the large impact cost or accompanying loss that they had to bear. Zerodha co-founder Nithin Kamath says, “When you don’t know exactly what the tech issue is, it is very tough to even communicate. What could have possibly been better is there was a SOP in place that if the exchange is shut, then trading will probably get extended till 5 PM. Then, we would not have to hurry and square up.”
Interoperability being fully implemented would have certainly helped both traders and the BSE, and would have seen even more cash trades flowing in. But that did not happen. For one, the February glitch happened due to problems at NSE’s clearing house. “At the same time that NSE halted trading, the primary server at NSE Clearing (NCL), which clears the trades for NSE, BSE and MSEI on an interoperable basis, was also shut down. This was one of the two major issues arising out of the trading glitch at NSE, the second being non-availability of NSE indices for trading on BSE. Trades at BSE are cleared through NCL and Indian Clearing Corporation (ICC), with around 85-90% of BSE’s trades now being cleared by NCL. While the slave server of NCL at BSE premises was operational, members were not able to increase their collateral at NCL and continue trading at BSE seamlessly as was envisaged as one of the key reasons for implementing interoperability,” says Mehta.
While there was some amount of interoperability with BSE allowing firms to transact using the last available info on collateral posted with NCL, and members being able to square off intra-day positions and trade on BSE for fresh equity purchases and sales, it was a lost opportunity for BSE. The earlier quoted fund manager says, “Given its market domination, NSE is now behaving like the BSE of yore. If incidents like the shutdown that happened on February 24 keep repeating, there is a chance for BSE to come back.”
The NSE has network effect on its side but seamless interoperability will definitely have a positive impact on BSE’s trading volume, believes Mehta. “As markets become more interoperable, liquidity on BSE too can rise significantly leading to higher trading volume and market share,” he explains.
Deep value or value trap
BSE’s cash market share and derivative market share is about 6% and 7%, respectively. Still, BSE has not thrown in the towel in the derivatives market and is experimenting with various indices. “S&P BSE Sensex 50 is a better index on which derivatives are offered in addition to Sensex 30. S&P BSE 50 has more than 99.97% correlation with Nifty and similar value. BSE’s value proposition for derivatives has increased even more in interoperability environment where the regulations permit cross margining in Sensex 50, Sensex 30 and Nifty,” elaborates Mehta.
Kamath feels the BSE would be better off focusing on the cash market than trying to capture share in F&O trading. “BSE has tried to push index contracts but it hasn’t picked up. It is tough to push an alternative when all the F&O trading is concentrated in Nifty and Bank Nifty. With the new rules and regulation on intra-day margin and leverage, my expectation is that volume will dip. So, BSE would be better off building the business around equity itself than F&O.” he reasons. Surely, beating the NSE at its own game will be far from a cakewalk, hence he adds, “If the same stock is more liquid on the NSE, why would someone trade on the BSE. It is for BSE to innovate, may be in terms of new indices or newer debt products or may be a newer order type.”
