Mumbai: Major development: U.S.-based trading firm Jane Street Group has deposited ₹4,843.5 crore (~$567 million) into an escrow account, in strict adherence to an interim SEBI order issued on July 3, 2025. With this deposit, the firm satisfies SEBI’s core condition, enabling it to resume trading in Indian equity markets under heavy regulatory scrutiny.
🔍 The Background: Alleged Manipulation in F&O Markets
-
On July 3, SEBI had barred Jane Street and related entities from trading, seizing ₹4,843 crore in suspected illicit profits.
-
The regulator accused Jane Street of artificially inflating India’s Bank Nifty and Nifty 50 indices. Its strategy allegedly involved pumping volumes in cash and futures early in the day, then leveraging opposing short positions in options—profiting from the eventual decline.
-
SEBI reportedly described this as a “sinister scheme,” implicating large-scale market distortion that impacted retail investors.
💸 Deposit Details & Conditions of Re-entry
-
The escrow deposit was routed through an Indian bank with a lien in SEBI’s favor.
-
According to SEBI’s Clause 62.11, once the deposit is made, the trading ban lifts—but under ongoing restrictions. Jane Street must not revert to any manipulative practices identified in the interim order.
-
Despite clearing the financial hurdle, Jane Street has temporarily halted options trading and retains the right to contest the allegations, likely through SEBI appeals and further legal reviews.
📉 Market Fallout & Exchange Impact
-
The F&O ban led to a slump of nearly 20% in derivatives volumes within a week, with daily index options turnover dropping by about 17–40%.
-
Indian exchanges—BSE and NSE—suffered a combined ₹1.4 lakh crore loss in market cap, with both nearing bear-market territory across several sessions.
⚖️ Jane Street’s Response & Next Steps
-
The firm denies SEBI’s allegations, labeling its index arbitrage strategy as routine and lawful.
-
It has retained top law firm Khaitan & Co. to mount a defense, with appeals likely headed to the Securities Appellate Tribunal (SAT), and potentially the Supreme Court.
-
SEBI has signaled plans to widen the probe to other indices including Sensex, Finnifty, and mid-cap weekly contracts.
🔭 Regulatory Implications & Market Vigilance
-
SEBI appears to be sharpening its approach toward high-frequency and algorithmic trading in Indian derivatives .
-
Going forward, exchanges are under strict instructions to closely monitor Jane Street’s trades to prevent recurrence.
-
The case underscores vulnerabilities in India’s F&O ecosystem, where large players could drastically sway market dynamics if unchecked.
