Capital market regulator Securities and Exchange Board of India (Sebi) has issued show causes notices (SCNs) to the National Stock Exchange (NSE) and 14 individuals as a part of probe against the exchange in the ‘unfair access’ controversy.
The case dates back to 2015 when the market regulator received three complaints letters highlighting flaws in NSE’s algorithm trading systems. The letters also made allegations of “unfair access” to certain brokers at the exchange’s collocation facility.
According to the letter, between 2011 and 2014, the set up at NSE allowed certain brokers (who connected first to the exchange’s system) received data ahead of others and thus were able to react to information before anybody else.
Following the letters, Sebi sets up a team to do fact-finding of the complaints in late 2015. Based on the preliminary finding, the Technical Advisory Committee (TAC) of Sebi constituted a committee to further examine the allegations against the country’s largest stock exchange.
In March 2016, the expert committee submitted its report to Sebi. The committee makes critical observations against the bourse stating it violated norms of fair access by allowing some brokers to benefit. It also alleged that the exchange didn’t immediately initiate any steps to check possibility of collusion between its staff and brokers. The expert committee also highlighted that NSE’s systems were prone to manipulation and as a result one OPG Securities was able to exploit its systems.
