NextFin News - Proprietary trading firms' profits from Indian derivatives fell to $4.7 billion in the financial year ended March 2026, a sharp contraction from the roughly $7 billion windfall that foreign funds and proprietary desks together extracted two years earlier, as the Securities and Exchange Board of India's 18-month campaign against speculative futures-and-options trading reshaped the country's 202 trillion rupee derivatives market. The squeeze on professional desks arrived alongside an 18% drop in retail investors' aggregate losses to 916.85 billion rupees ($9.61 billion) - yet the average loss per remaining trader actually rose to 116,654 rupees from 113,913 rupees a year earlier, underscoring that the regulatory crackdown has thinned the herd without making the game any safer for those still playing.
The twin data points, released by the Finance Ministry in a written reply to Parliament, frame the central tension of India's derivatives crackdown: the market's most sophisticated players are earning less, and the retail crowd is shrinking, but the structural mismatch that transfers wealth from households to algorithms has not disappeared - it has merely been compressed.
The Two-Sided Ledger: Less Money for Everyone, but the Game Is Unchanged
The numbers tell a story of a market being deliberately squeezed from both ends. Proprietary traders' derivatives profits fell to $4.7 billion in the year ended March 2026, down from the $7 billion in gross profits that algorithms helped foreign funds and proprietary desks extract in the 12 months to March 2024, according to the regulator's own study. Total derivatives turnover declined to 202 trillion rupees from 213 trillion rupees year-on-year, and the number of individual investors trading equity derivatives fell by nearly a fifth, to 7.86 million from 9.81 million.
But the aggregate decline in retail losses - to 916.85 billion rupees ($9.61 billion) from a peak of 1.12 trillion rupees in the fiscal year ended March 2025 - masks a more uncomfortable detail. With fewer participants chasing the same zero-sum game, the average loss per trader ticked higher, not lower. The government's data, drawn from SEBI's analysis of the top 15 brokers representing roughly 90% of all individual investors in the equity derivatives segment, showed that nine out of ten retail traders still lost money on average in a market that remains the world's largest equity derivatives venue by volume, home to more than 130 million retail traders.
That is the paradox at the heart of the crackdown: regulators set out to protect households from a wealth-transfer machine, and they have succeeded in reducing the machine's throughput - but the machine itself, the structural advantage of speed, capital, and information that professional desks hold over individuals, is intact.
The Regulatory Squeeze: How the Easy-Money Era Ended
The profit compression did not happen by accident. It is the direct result of a sequenced regulatory campaign that began in late 2024 and has continued into 2026, each measure removing a piece of the infrastructure that made Indian index options unusually lucrative for high-frequency and proprietary firms.
The first blow was product design. SEBI limited weekly options contracts to a single benchmark index per exchange, dismantling the hyper-frequent expiry cycle that had turned index options into a high-velocity trading game. Weekly expiries had compressed the options lifecycle into seven-day windows, generating repeated gamma exposure and forcing market makers and retail traders alike to churn positions at a pace that favored the fastest algorithms. Removing most weekly contracts reduced the number of trading opportunities and, critically, the repeated friction costs that retail traders paid and prop desks collected.
The second blow was capital. In July 2026, the Reserve Bank of India moved to curtail the intraday overdraft facilities that banks had extended to proprietary trading firms, effectively raising the cost of the leverage that prop desks use to scale small per-trade edges into billion-dollar profit pools. The impact was immediate: average daily futures-and-options turnover fell 27.1% in July to 1.7 trillion rupees ($17.65 billion), the lowest level since November 2023, exchange data showed.
"It is going to be hard to find alternate sources of funding. There are non-bank lenders, but that would be expensive," said Rajesh Baheti, managing director at Mumbai-based proprietary trading firm Crosseas Capital Services, after the central bank's measures took effect.
The third blow was enforcement. SEBI's action against Jane Street Group - barring the U.S. firm from the local securities market and moving to seize $570 million in what the regulator called unlawful gains from trades that generated billions in profits between January 2023 and March 2025 - sent an unambiguous signal to the high-frequency trading community operating out of Mumbai's trading towers. Jane Street has disputed the findings, arguing it was employing legitimate hedging strategies, but the message to the industry was clear: the regulatory tolerance for strategies that profit from moving prices against smaller traders has closed.
Together, these measures attacked the three inputs of proprietary profitability - opportunity frequency, leverage, and permissiveness - and the $4.7 billion figure is the arithmetic result. This is not a cyclical dip in trading profits; it is the deliberate decommissioning of a business model.
The Zero-Sum Mechanism: Why Prop Profits and Retail Losses Move Together
To understand why prop desks are earning less, it helps to understand where their profits came from. India's equity derivatives market is, for the retail segment, structurally negative-sum: transaction costs, taxes, and the bid-ask spread mean that before any alpha is generated, the pool of retail money is already shrinking. The regulator's study found that in the year ended March 2024, proprietary trading firms and foreign portfolio investors together booked roughly 61,000 crore rupees - about $7.3 billion - in gross profits from equity derivatives, a combined windfall that flowed from the losing side of the ledger to the winning side.
The concentration was extreme. Between 96% and 97% of those profits for proprietary traders and foreign investors respectively came from participants who used algorithmic orders at least once during the year - a technical way of saying that the wealth transfer ran through code, not conviction. Retail traders, by contrast, lost money with a consistency that bordered on statistical certainty: the study of the three years from fiscal 2022 to 2024 found that 93% of individual F&O traders incurred losses, with only 1% making profits above 100,000 rupees after costs.
Here is the mechanism that ties the two halves of the ledger together. Proprietary and high-frequency firms profit from three edges: speed (executing ahead of slower order flow), structure (collecting the spread and capturing predictable retail flow patterns around weekly expiries), and leverage (scaling tiny per-contract edges into large absolute gains). Retail traders supply the flow - the predictable, often directional, often late-to-the-move order flow that gives the algorithms something to trade against. When regulators shrink retail participation by 20% and reduce turnover by 5%, they are not just protecting households; they are shrinking the prop desks' prey base.
That is why the $4.7 billion figure should not be read as a sign that retail traders are winning. It is a sign that the market is smaller. The average retail loss per trader rose even as aggregate losses fell, which means the survivors are losing at the same rate as before - they are just fewer in number. The wealth-transfer mechanism has been throttled, not reversed.
Cyclical or Structural: This Is a Regime Shift, Not a Bad Year
The critical question for anyone reading the $4.7 billion figure is whether it represents a cyclical trough - a bad year that will revert once volumes recover - or a structural break that will not self-correct. The evidence points decisively to structural.
A cyclical decline in trading profits would be driven by transient factors: a quiet volatility regime, a temporary funding squeeze, a pause in retail enthusiasm that eventually reignites. None of those conditions holds here. The drivers are durable by design:
Product design is permanently less favorable. The weekly-expiry restrictions are a rule change, not a market condition. Exchanges cannot quietly restore multiple weekly expiries per index without reversing a stated regulatory directive. The opportunity frequency that powered high-frequency profits has been structurally reduced.
The funding plumbing has been rewired. The central bank's curbs on intraday overdrafts changed the cost of capital for prop desks at the source. Even if firms find alternative funding through non-bank lenders, as Baheti noted, that capital is more expensive - which permanently compresses the return on leveraged strategies that depend on thin margins at high volume.
Enforcement risk is now priced in. The Jane Street action created a precedent. High-frequency firms now face a non-zero probability that profitable strategies will be reclassified as manipulative after the fact. That raises the required return on any strategy that profits from order-flow dynamics, and it discourages the very capital that would otherwise re-enter the market.
Retail participation has a floor below its peak. The 20% decline in individual traders followed explicit regulatory measures - higher transaction costs, reduced product frequency, and a public campaign by the regulator emphasizing that nine of ten traders lose. Household savings are being redirected toward mutual funds and insurance through policy channels; the demographic wave that fed the F&O boom is being deliberately diverted.
For a cyclical call to hold, you would need to see mean reversion in at least one of these channels - volumes returning to 213 trillion rupees, weekly expiries restored, bank funding loosened, or retail participation rebounding toward 130 million traders. None is on the horizon. The profit pool for proprietary desks has been structurally resized, and $4.7 billion is closer to the new normal than to a trough.
The Counter-Thesis: Curbs May Push Risk Into the Shadows
The strongest argument against the regulatory success story is that it mistakes visibility for safety. By making listed index options less attractive, SEBI has not eliminated speculative demand - it has displaced it. The counter-thesis holds that risk migrates rather than disappears: into unregulated offshore venues, into cryptocurrency derivatives, into over-the-counter arrangements, or into the small but growing retail prop-trading-firm industry that packages leveraged speculation as education.
There is precedent for this pattern. When China tightened restrictions on onshore crypto and derivatives activity, trading volumes did not vanish; they relocated to offshore exchanges and peer-to-peer channels where consumer protections were weaker and regulatory reach was nil. The same dynamic could unfold in India: a retail trader priced out of Nifty weekly options by higher transaction costs does not necessarily become a long-term equity investor - they may simply find a venue with fewer guardrails.
There is also a liquidity argument. Proprietary and high-frequency firms, for all their extraction, provide genuine market-making services: they narrow spreads, absorb order flow, and keep the market liquid enough for hedgers and genuine price-discovery participants to transact. If the profit pool shrinks enough to drive these firms out - or to drive them to Singapore and London, as some Indian HFT startups have already begun to do - the market could become less liquid, with wider spreads that hurt the very retail investors the rules were designed to protect. A thinner, less liquid market with fewer professional participants could end up more dangerous for the households that remain.
This counter-thesis is not fanciful, but it has a specific falsifying signal. If the next SEBI study - covering fiscal 2027 - shows retail aggregate losses falling again while the number of individual traders stabilizes or grows, and while derivatives turnover remains anchored near current levels rather than migrating offshore, then the displacement argument fails and the regulatory model is validated. Conversely, if retail losses rise again or turnover collapses below 150 trillion rupees while offshore crypto-derivatives volumes surge, the counter-thesis wins: the risk has not been reduced, only relocated.
What Comes Next: Beneficiaries, the Exposed, and Three Scenarios
The immediate beneficiaries of this regime shift are the asset managers and mutual-fund industry that are absorbing redirected household savings, and the brokers whose revenues are less dependent on F&O churn. The exposed parties are the proprietary trading firms themselves - particularly the mid-sized desks that relied on leverage and weekly-expiry velocity - and the exchanges and brokers whose fee income scaled with derivatives turnover. SEBI's own annual report for 2025-26 showed proprietary traders accounting for 57% of non-agricultural derivatives turnover, a concentration that leaves exchange revenues sensitive to any further prop-desk exodus.
Short term (6-12 months): expect continued profit compression. The central bank's funding measures only fully bite as existing bank guarantees expire, and brokers have noted that many prop traders locked in one-year guarantees before the July rules took effect. Volumes should drift lower before they stabilize, and prop profitability should remain under pressure.
Medium term (1-3 years): the market re-equilibrates around a smaller, less retail-dominated participant base. The surviving prop desks are those that can adapt - shifting from pure flow extraction to genuine market-making and hedging services, or relocating part of their operation to other Asian venues. Retail aggregate losses should continue to fall, but the average loss per trader is the number that matters, and it will only improve if the remaining participants are better educated rather than just fewer.
Long term (3+ years): the structural question is whether India's household savings rate can be successfully redirected into productive capital formation - equities held for the long term, mutual funds, insurance - rather than speculative churn. That is the regulator's stated objective, and the derivatives crackdown is one instrument in a broader policy toolkit. If it works, the $4.7 billion figure will come to be seen as the moment India's derivatives market grew up. If it fails, it will be remembered as the moment speculation went underground.
Three scenarios frame the path:
- Base case: prop profits stabilize in the $4 billion to $5 billion range, retail participation bottoms near 7 million traders, and aggregate retail losses continue to decline gradually as turnover normalizes at a lower level.
- Upside case (for regulators): the savings redirection succeeds, mutual-fund inflows accelerate, and the derivatives market becomes a genuine hedging venue dominated by institutional participants - the $4.7 billion becomes a floor, not a ceiling, but with profits earned from providing liquidity rather than extracting it.
- Downside case: speculative demand migrates offshore or into unregulated venues, domestic derivatives liquidity deteriorates, spreads widen, and retail losses re-accelerate in a less transparent market - in which case the crackdown protected the ledger more than it protected investors.
The falsifying signal for the base case is straightforward: if proprietary profits rebound above $6 billion within four quarters without a corresponding restoration of weekly expiries or bank funding, then the structural-break thesis is wrong and the profit pool is more cyclical than this analysis assumes.
India's derivatives crackdown has achieved its narrow objective - it has made the market less profitable for the players who were winning and less accessible to the households who were losing. What it has not yet proven is that it has made the market safer, or that the savings it redirects will find their way into productive investment rather than into a riskier shadow venue. The $4.7 billion figure is not a victory lap; it is the invoice for a business model that regulators decided India could no longer afford.
