Jane Street was prevented from Indian markets in the investigation by Sibi star-news.press/wp

According to the temporary request of 105 -page Seebi, Jin Street will buy strongly large quantities of stocks and future contracts that are part of the bank index, which tracks the performance of the banking sector in India, early in the trading day. The quantum trading company will put great bets on the fact that the index will decrease later in the day.

Jin Street will then sell the situations she bought earlier, withdraw the index less and make her previous bets in the options market more profitable.

While Jin Street will bear some losses, Sibi claimed that he was part of a “deliberate strategy to address indicators in favor of trading and attitudes”, and the losses were compensated through the company’s larger and profitable options.

Although these measures were not a violation of any regulations, Sibi said that “the tremendous intensity and scale” of its intervention, and the rapid reflection of their trading “without any reasonable economic justifications, unlike the simultaneous activity in their positions in the banks’ options markets markets, “.

Sibi pointed out that repeated trading cases continued in the broader criterion of 50 errors, even after the National Stock Exchange of India was issued “explicit advisory” in February 2025.

“Such a terrible behavior, in a clear disregard/ challenge to the explicit consultant issued by NSE in February 2025, shows that, unlike the vast majority of investors in foreign portfolios and other market participants, Jin Street said.

“It is no longer possible to detain the safety of the market, and the belief of millions of investors and young merchants, as hostages of such a reliable representative.”

Divin Chocsi, the founder and director of the wealth management, said the SEBI campaign in Jane Street is a “good example”.

He told CNBC: “Any player who misunderstood the market requires showing discipline. The organizer does his work to maintain the safety of the market.”

Chocsi added that the implementation of trading can be allocated based on the needs and file of the merchant definition, the discovery of the price in the market should be “global for all.”

Kraanthi Bathini, director of the stock strategy at Wealthmills Securities, noted that some companies may “enter the market with innovative and innovative strategies to exploit investors.” Therefore, Sebi needs to “protect the interests of retail investors”, added.

Bathni said that any effect on the markets as a result of this decision will be short -term.

The SEBI step comes at a time when many other global trade companies, from Citadel Securities and IMC trading to Millennium and Optiver, intensify their presence in India, to ride the prosperous derivative markets, which are the largest in the world through traded contracts.
