Are we ready to handle market manipulations in electricity derivatives?
The Jane Street case: A wake-up call
The JSG case exposed classic intraday manipulation. The group purchased large volumes of BANKNIFTY index and constituent stocks early in the trading day, driving prices upward. Concurrently, it took reverse positions in the options market. Later, they offloaded their holdings, pulling down prices and reaping disproportionate profits in the derivative segment, while absorbing manageable losses in the cash market.
This trading pattern, which came to light through a US court case in April 2024, evaded Sebi and exchange surveillance for over 15 months until interim orders were finally issued on July 3, 2025. Notably, the detection did not stem from domestic oversight but through disclosures in litigation abroad.
Sebi's timeline illustrates the vulnerability of surveillance systems, even when both cash and derivative markets are governed by the same regulator (Sebi) and the exchange ecosystem is tightly knit (NSE). The strategy deployed by JSG hinged on exploiting illiquidity in the cash segment and leveraging high liquidity in derivatives—particularly BANKNIFTY options around expiry periods.
Electricity spot markets: The challenge of dual regulation
The electricity market, structured differently, introduces additional layers of complexity. Three power exchanges—Indian Energy Exchange (IEX), Power Exchange India Limited (PXIL), and Hindustan Power Exchange (HPX) — serve primarily the Day Ahead Market (DAM) and Real-Time Market (RTM). IEX dominates both, handling roughly 3.9 per cent and 2.47 per cent of national generation respectively, amounting to just 7 GW and 4.8 GW in traded capacity. These figures do not reflect a truly liquid market.
Further complicating matters, derivative contracts will be settled at prices derived from IEX and PXIL — despite PXIL's minimal volumes. In contrast to equities, where Sebi governs both segments, electricity markets have split jurisdiction: the Central Electricity Regulatory Commission (Cerc) oversees spot contracts, while Sebi regulates derivatives.
Some of the large power generators individually control substantial capacity. As such, their ability to influence prices in illiquid markets is undeniable, especially since comprehensive trade disclosures aren't mandated under current protocols.
Launch of electricity derivatives: Regulatory coordination is key
With derivative contracts having debuted on MCX (July 10, 2025) and set to debut on NSE (July 14, 2025), regulatory silos present risks. While volume caps have been prescribed to prevent distortions, these are not fail-proof. Coordination between Sebi and Cerc must be seamless. Miscommunication or lag in action could have ripple effects — raising costs for electricity consumers and undermining market integrity.
The JSG episode underscores the need for real-time surveillance, rapid response frameworks, and clear inter-regulatory protocols. If Sebi's mechanisms struggled with manipulations in tightly monitored equity markets, can the electricity sector — divided between two regulators — claim immunity?
Time to ringfence and reform
India's electricity derivative market is at a formative stage. This moment demands a forward-looking approach. Regulators must not only anticipate the nature of manipulative strategies but act decisively to prevent their execution. Surveillance infrastructure must be upgraded, communication lines clarified, and cross-market behaviour monitored in tandem.
Regulatory failures in one segment must not cascade into others. It is imperative for Sebi and Cerc to insulate their constituencies, proactively guard consumer interests, and evolve with the market. While early action may have been missed, the JSG case offers a chance to set the ball rolling before it's too late.

SEBI aims to deepen equity market, flags concerns over derivatives frenzy
SEBI on Thursday expressed concern over the growing dominance of ultra-short-term derivatives trading, cautioning that such trends could undermine the health of India's capital markets, while contemplating steps to extend the tenure and maturity of these products. Very short-term derivatives continue to dominate equity derivative volumes, especially expiry-day index options. This is an imbalance that is obviously unhealthy and may have potential for adverse consequences," said SEBI Whole-Time Member Ananth Narayan. He was addressing the 11th Capital Markets Conclave organised by the CII. "I would strongly endorse the view that, towards this end, we must look for ways to further deepen our cash equities markets, even as we look to improve the quality of our derivatives market by extending the tenure and maturity of the products and solutions on offer. We need constructive engagement from all stakeholders to achieve this," he said. Citing the market regulator's own research, Narayan pointed out that 91 per cent of individual traders in futures and options (F&O) incurred net losses in FY25 - collectively losing over Rs 1 lakh crore - funds that could otherwise contribute to responsible investing and capital formation. He highlighted that the Indian derivatives market is unique, with expiry-day index option turnover often exceeding the cash market by as much as 350 times. Unlike longer-term derivatives, these short-term products contribute little to capital formation and may actually add to market volatility, Narayan said. While acknowledging that exchanges, brokers, and other intermediaries have significant revenue dependence on such trading volumes, the SEBI official questioned the sustainability of this trend. Is all this at all sustainable? he asked. SEBI has already introduced regulatory measures in October 2024 and May 2025 aimed at curbing excesses in this space, which Narayan said are showing some early signs of moderation. However, he emphasised the need for continuous engagement with stakeholders to ensure that both capital formation and market health are protected. We must look for ways to deepen our cash equities markets while improving the quality of derivatives through longer-tenure products, Narayan said, urging industry collaboration. Responding to a question, he underscored the advantages of listing, particularly in the current environment where valuations are very, very attractive. Going public can unlock substantial value and enable companies to raise capital in a very meaningful manner, acting as a force multiplier for achieving scale and growth. SEBI is working to boost participation and innovation across asset classes by enhancing transparency in corporate bonds, InvITs, REITs, municipal bonds, and expanding commodity derivatives. It has urged all stakeholders to support these efforts. Narayan underscored that preserving trust is the key ingredient for healthy capital markets. Our funds ecosystem has grown significantly with substantial growth in both issuances and investments. Something good is underway around capital formation, he noted. However, he warned that unchecked speculation, governance failures, technology lapses, market manipulation, or flawed market design (Type I errors) could destroy investor trust and kill the goose that is laying golden eggs. At the same time, he cautioned against over-regulation (Type II errors) that might stifle legitimate business or capital formation. We in SEBI look at both risks very closely and undertake extensive consultations to minimise both together, he assured. Narayan urged exchanges, clearing corporations, and depositories to maintain strong operational resilience and risk management while balancing commercial interests with public trust. He also called upon intermediaries and industry players to act as trusted advisors. When you see something wrong, please say something. And when you seek regulatory relief, please engage with us openly on how risks of potential Type I errors will be mitigated, he said. Narayan also emphasised that compliance with disclosure and governance standards associated with being a listed entity enhances long-term sustainability, likening transparency to sunlight being the best disinfectant. He expressed a personal hope to see more micro, small, and medium enterprises (MSMEs) list and grow into large national champions, though he reiterated that the choice ultimately rests with promoters.
