Shares of BSE Ltd., Asia\u2019s oldest stock exchange, soared 17% on March 28 after its competitor, National Stock Exchange (NSE), decided to defer its plan to shift derivatives expiry days to Monday.<\/p>\n
This sharp rally in BSE\u2019s stock price, which was trading at \u20b95,494 per share at 10:50 AM, came after the Securities and Exchange Board of India (SEBI) released a consultation paper proposing a uniform expiry day framework across exchanges. SEBI suggested that all equity derivatives contracts should have expiry days limited to either Tuesday or Thursday to ensure better market efficiency.<\/p>\n

According to sources, SEBI has advised stock exchanges not to proceed with any changes to derivatives expiry days until further clarity is provided. NSE had earlier announced that it would shift its weekly, monthly, and quarterly derivatives expiry from Thursday to Monday, a move that had triggered a sharp selloff in BSE\u2019s stock.<\/p>\n
Following SEBI\u2019s intervention, NSE is expected to issue a circular confirming that it will maintain the status quo for now. The regulator has also proposed that exchanges must seek prior approval before modifying contract expiry dates to avoid market disruptions.<\/p>\n
SEBI has directed exchanges to maintain current expiry schedules.<\/p>\n<\/li>\n
NSE may soon confirm in an official circular that no changes will be made.<\/p>\n<\/li>\n
Exchanges will now require regulatory approval before modifying expiry schedules.<\/p>\n<\/li>\n<\/ul>\n
The stock price movement of BSE Ltd. over the past few days has been highly volatile, largely influenced by the expiry schedule changes. When NSE initially announced its move to shift expiry days to Monday, BSE\u2019s shares tumbled by 9% due to concerns over reduced trading volumes and liquidity on its platform.<\/p>\n
Market participants believed that a shift in NSE\u2019s expiry days would significantly impact BSE, as its Sensex-based derivatives currently expire on Tuesdays. The fear was that traders would gravitate towards NSE\u2019s new expiry day, further eroding BSE\u2019s market share in the futures and options (F&O) segment.<\/p>\n
However, with SEBI stepping in and NSE deferring its plans, BSE has managed to recoup most of its recent losses, bringing some relief to investors.<\/p>\n
BSE shares had earlier fallen 9% due to concerns over declining liquidity.<\/p>\n<\/li>\n
Traders feared NSE\u2019s Monday expiry could hurt BSE\u2019s derivative segment.<\/p>\n<\/li>\n
With SEBI\u2019s intervention, BSE has reversed most of its losses.<\/p>\n<\/li>\n<\/ul>\n
The development has also prompted brokerage firms to reassess the impact of NSE\u2019s proposed changes on BSE\u2019s business model.<\/p>\n
According to Jefferies, the initial concern was that BSE could lose market share, which would result in a 12% earnings per share (EPS) impact. However, with SEBI pushing for a more balanced expiry day distribution, the brokerage believes that BSE\u2019s downside risks are now significantly lower.<\/p>\n
Jefferies further noted that while clarity on open interest limits is still awaited, maintaining the current Tuesday and Thursday expiry framework could prevent a major disruption in trading patterns.<\/p>\n
Meanwhile, Nuvama Research had earlier warned that NSE\u2019s move to shift expiry days to Monday could hurt overall industry trading volumes, particularly impacting retail traders who rely on multiple trading avenues. With NSE now deferring its decision, some of these concerns have been alleviated.<\/p>\n
Jefferies: BSE\u2019s market share loss concerns have eased.<\/p>\n<\/li>\n
Jefferies: 12% EPS impact previously estimated may not materialize.<\/p>\n<\/li>\n
Nuvama Research: Industry trading volumes would have been affected by NSE\u2019s Monday expiry.<\/p>\n<\/li>\n<\/ul>\n
With SEBI taking a proactive role in regulating derivatives expiry schedules, market analysts expect further discussions on how to best distribute expiry dates across exchanges to avoid excessive concentration of liquidity on any single platform.<\/p>\n
For now, the regulator\u2019s stance provides a temporary relief for BSE, which had faced significant uncertainty over its F&O segment\u2019s future. If NSE reverts to its Thursday expiry schedule, while BSE continues with its Tuesday expiries, the market could see a more balanced distribution of trading activity.<\/p>\n
As the situation continues to develop, investors will be watching closely for further regulatory announcements and potential shifts in trading behavior across India\u2019s two largest stock exchanges.<\/p>\n","protected":false},"excerpt":{"rendered":"
