BSE Ltd , the operator of the Bombay Stock Exchange, saw its shares decline by 4% following news that the Securities and Exchange Board of India (SEBI) is expanding its investigation into alleged index manipulation by Jane Street. The regulatory body is now including Sensex options in its probe, which was initially focused on Nifty and Bank Nifty weekly options.

Widening Scope of Investigation

The expansion of SEBI's investigation to include Sensex options marks a significant development in the ongoing probe against Jane Street, a global trading firm. This move suggests that the regulator is casting a wider net to examine potential market manipulation across multiple Indian stock indices.

Impact on BSE Ltd

The news of the expanded investigation has had an immediate impact on BSE Ltd's stock price, with shares dropping 4% in response to the announcement. This decline reflects investor concerns about the potential implications of the probe on the exchange's operations and reputation.

SEBI's Actions Against Jane Street

SEBI has already taken strong action against Jane Street in connection with the ongoing investigation:

• The regulator has barred Jane Street and related entities from participating in the Indian market.
• SEBI has ordered Jane Street to deposit alleged illegal gains amounting to Rs 4,843.50 crore.

Implications for Market Integrity

This expanded investigation underscores SEBI's commitment to maintaining the integrity of Indian financial markets. By scrutinizing the trading activities in Sensex options, the regulator aims to ensure fair and transparent market operations across all major indices.

The outcome of this investigation could have far-reaching consequences for market participants and may lead to enhanced regulatory measures to prevent index manipulation in the future.

As the investigation unfolds, market participants and investors will be closely watching for any further developments that could impact BSE Ltd and the broader Indian stock market landscape.
