BSE Ltd. , India's 150-year-old stock exchange, has made substantial strides in capturing market share for index options contracts, particularly on expiration days. This shift comes in the wake of regulatory changes implemented by the Securities and Exchange Board of India (SEBI).

Market Share Surge on Expiry Days

BSE has seen a remarkable increase in its market share of options premium turnover on expiry days. Since mid-July, the exchange has been consistently capturing 50% or more of the options premium turnover on most expiry days, a significant jump from its 35% share in April.

Strategic Expiration Day Change

A key factor contributing to BSE's growth was its decision to switch its derivatives expiration day from Tuesday to Thursday. This move was made in response to the National Stock Exchange (NSE) shifting its expiration day to Tuesdays. The strategic change has allowed BSE to capitalize on the new market dynamics.

NSE's Market Position

Despite BSE's gains, the National Stock Exchange continues to dominate the overall volume in India's derivatives market:

• NSE holds nearly 80% of total derivatives contracts
• However, NSE has experienced a substantial decline in its monthly options premium turnover, dropping more than 40% through August compared to October

Regulatory Impact on Options Market

SEBI's regulatory crackdown on India's options market has played a significant role in reshaping the landscape:

• Elimination of weekly NSE Nifty Bank Index options
• Increase in minimum limits to reduce retail investor speculation

Trader Preferences Shifting

Analysts anticipate BSE to continue gaining market share in the options segment. Traders are increasingly viewing Sensex options as preferred contracts for macro events, indicating a shift in market sentiment.

BSE Share Price Performance

Despite the positive developments in market share, BSE's stock has faced some headwinds:

• BSE's share price has declined 32.00% from its June record high
• The drop is attributed to concerns about the impact of regulatory changes on the exchange's business

The evolving dynamics in India's options market, driven by regulatory changes and strategic moves by exchanges, continue to reshape the competitive landscape. BSE's recent gains in market share highlight the potential for significant shifts in trader preferences and market structure in response to regulatory and competitive pressures.
