The finance ministry has asked markets regulator Sebi to take the necessary measures to address the issues which led to the outage at National Stock Exchange recently. In a written reply to the Lok Sabha on Monday, the Minister of State for Finance Anurag Singh Thakur said that on February 24, 2021, the National Stock Exchange of India Limited (NSE) took a decision to halt trading from 11:40 am which was caused due to technical issues.

However, the system of interoperability among clearing corporations, which allows market participants to consolidate their clearing and settlement functions at a single clearing corporation, irrespective of the stock exchange on which the trade is executed, continued to remain functional.

The trading at NSE resumed from 03:30 pm and trading hours were extended from 03:30 pm to 05:00 pm for the day in all the three stock exchanges -- NSE, BSE and MSEI -- to enable investors to square off their existing positions.

DEA has further advised SEBI to take necessary measures to ensure that all the underlying issues leading up to the market disruption are addressed appropriately," the minister said.
