In one of many greatest crackdowns in India’s fairness market, the Securities and Change Board of India (Sebi) ordered seizing ₹4,843 crore from the group, one of the vital influential gamers within the world derivatives markets, citing prima facie proof of index manipulation and fraudulent buying and selling practices.
The Sebi interim order additionally froze the financial institution and demat accounts of the 4 entities, and directed all custodians, banks, depositories, and registrar brokers to dam any transfers or redemptions involving the entities’ property with out its approval.
Concern issue
Capital market-related shares plunged on fears of a fall in volumes.
Shares of BSE tanked 6.55% to ₹2,635.2 whereas Nuvama, a buying and selling companion of Jane Avenue in India, dropped 11.2% to ₹7,310. Angel One, the third-largest retail broking home, plunged 5.9% to ₹2,776. Depository CDSL, a subsidiary of BSE, shed 2.3% to ₹1,762.5. Others like Motilal Oswal Monetary Providers and Aditya Birla Solar Life MF slipped by 1.3–1.6%.
“Jane Avenue disputes the findings of the Sebi interim order and can additional interact with the regulator. Jane Avenue is dedicated to working in compliance with all laws within the areas we function world wide,” the group stated in an announcement to Mint.
The Sebi order cited what it describes as “prima facie” proof of two distinct however coordinated manipulation methods: “intraday index manipulation” (seen on 15 days) and “prolonged marking the shut” (seen on 3 days), notably on index expiry days. An additional occasion of comparable manipulation was recorded on 15 Could 2025, in defiance of prior regulatory warnings.
Index manipulation
Sebi stated Jane Avenue exploited expiry-day dynamics in index derivatives. It held massive choices positions early within the day—usually places (bearish bets) or calls (bullish bets)—after which moved costs within the money and futures markets to learn its choices e book. On expiry mornings, it will push Financial institution Nifty up by aggressively shopping for constituent shares and futures, solely to reverse positions by noon to engineer a fall—boosting the worth of its put choices.
Throughout all of the 18 days recognized by Sebi for investigation throughout the examination interval, Jane Avenue earned ₹43,289 crore in index choices and one other ₹900 crore in inventory choices, whereas making losses of ₹7,208 crore in inventory futures, ₹191 crore in index futures, and ₹288 crore in money fairness. The web revenue earned by the group stood at ₹36,502 crore.
On 17 January 2024, Sebi discovered that Jane Avenue earned ₹734.93 crore in choices, whereas shedding ₹61.6 crore in money and futures—what Sebi calls the “price of manipulation.” That day, Financial institution Nifty opened 3.2% decrease, pushed by poor earnings from HDFC Financial institution. Between 9:15 am and 11:47 am, Jane Avenue bought ₹4,370 crore price of Financial institution Nifty constituent shares and futures. This pushed the index up, deceptive the market. Then, it created ₹32,114.96 crore in bearish positions by shopping for places and promoting calls. After 11:49 am, it reversed its morning trades, sending the index right into a tailspin and locking in large income.
Directional trades
In one other technique labelled “prolonged marking the shut”, Jane Avenue was discovered to have made aggressive directional trades within the last 30-60 minutes of buying and selling to engineer the index closing degree. This was key since settlement costs for choices are derived from the day’s shut.
In a very severe occasion, on 15 Could, 2025—regardless of receiving a previous warning from the Nationwide Inventory Change (NSE)—the identical sample re-emerged, this time on Nifty expiry. Sebi famous this was a “cynical violation of the warning letter issued to the JS Group on February 6, 2025.”
Forensic evaluation
The investigation, which started in April 2024 after overseas media studies flagged world litigation involving Jane Avenue’s buying and selling methods, targeted on derivatives expiry-day trades. Forensic evaluation of timestamps, order placement vs. final traded value, and gross traded values revealed patterns carefully tied to its choices exposures. In keeping with Sebi, this indicated a calculated design to control index ranges.
Authorized specialists say the burden now shifts to Sebi to show manipulative intent.
“Massive, aggressive, and even dominant buying and selling methods aren’t per se illegal except they’re misleading or fraudulent. Sebi’s case depends on patterns and value influence somewhat than direct proof of deception, which may face scrutiny. This matter may set an vital precedent for the way Indian regulation treats advanced algorithmic methods within the derivatives market,” stated Sumit Agrawal, founding father of Regstreet Regulation Advisors and a former Sebi official.
Agarwal added that if contested, Jane Avenue may plausibly argue that its trades have been a part of official algorithmic methods used for hedging and liquidity provision, not manipulation. “The trades have been executed transparently by the alternate and should have precipitated market influence as a result of scale, however influence alone isn’t illegal below Indian securities regulation”, he stated.
Main reset
Jayesh H., co-founder of Juris Corp, added, “Whereas it might probably seem as one-off, that might be a mistake. If the preliminary evaluation seems to be right, then there must be a significant reset and on all sides… Going again in time, the suggestions of L.C. Gupta needs to be remembered… small retail traders [were] to be saved out.”
A Sebi official stated on the situation of anonymity that the interim order isn’t a present trigger discover, and it clearly signifies that investigations into Jane Avenue will proceed. “This interim order has solely regarded on the 18 main days of prima facie Financial institution Nifty index manipulation on expiry day… Investigations into different expiry days, different indices (together with throughout exchanges), and different potential patterns apart from the 2 highlighted within the order might want to proceed.”
There shouldn’t be any main market influence from this enforcement motion, the official added. “In any case, delta-based (future equal) limits are actually in place in index choices to curtail extreme threat taking with out impacting common individuals.”
Enforcement
Higher enforcement of present laws can pave the way in which for optimum regulation, the official stated. “On the flip aspect, extra laws can’t make up for poor enforcement. We are going to proceed to observe Indian F&O markets.”
The order, authored by Sebi whole-time member Ananth Narayan G, mandated Jane Avenue to shut all open by-product choices in three months. Exchanges have been requested to oversee the group’s buying and selling, which can start after it deposits alleged unlawful positive factors.
Market specialists seem to have combined views on the implications of the Sebi motion on the US buying and selling agency.
“You have to hand it to Sebi for going after Jane Avenue. If the allegations are true, it is blatant market manipulation,” stated Zerodha founder Nithin Kamath on X.
He added, although, that prop buying and selling corporations like Jane Avenue accounted for almost 50% of choices buying and selling volumes, and in the event that they pulled again—which appears possible—retail exercise of round 35% may take successful. “So this could possibly be dangerous information for each exchanges and brokers,” Kamath stated.
Greater volumes?
Nevertheless, a UAE-based dealer energetic in Indian markets countered this view, saying volumes may truly rise.
“The influence of the Sebi clampdown on Jane Avenue’s manipulation will solely result in a rise in volumes,” stated Mayank Bansal, president at a UAE-based hedge fund. “Many merchants stayed out of the Indian markets over the previous 12 months, realizing that markets have been being rigged massively by Jane Avenue on expiry day. Now that Jane Avenue has been barred… the volumes… will truly enhance as merchants staying out will come again in once more.”
Jane Avenue is essentially a market maker in different markets the place it operates. Right here, as an alternative of offering two-way liquidity, it was taking massive directional publicity by way of choices, after which manipulating the underlying to learn from them.
NSE’s premium turnover in index choices—a key metric for energetic buying and selling—averaged ₹47,836 crore per day in Q1 FY26. That’s down 24% year-on-year from ₹63,208 crore, however up 10% from the earlier quarter.
The year-on-year fall is attributed to Sebi’s tighter guidelines launched late final yr, which elevated the price to commerce and restricted weekly choice expiries to at least one per alternate.
BSE holds somewhat over 20% share of the choices market.
