F&O STT hike: retail trading faces higher costs

India’s futures and options (F&O) market is going through a policy-led reset. Social media discussion has focused on two forces moving together: SEBI’s tightening of index derivatives since late 2024 and the Union Budget 2026 decision to raise securities transaction tax (STT) on derivatives from April 1, 2026. Regulators have framed these steps as investor-protection measures aimed at cooling excessive speculation. The most visible early outcome is a sharp fall in retail participation after years of steady expansion. At the same time, government data shows aggregate retail losses in equity derivatives have declined, even though losses for the remaining active traders still look large on a per-person basis.

What changed in India’s F&O policy playbook

SEBI began rolling out a set of measures from November 2024 onwards. Weekly index derivatives were rationalised to reduce excess activity. Tail-risk coverage on the day of options expiry was increased. Contract sizes for index derivatives were raised. Upfront collection of option premiums from buyers was introduced. SEBI also removed calendar spread treatment on the expiry day and started intraday monitoring of position limits. In May 2025, SEBI added steps to streamline expiry days across exchanges and apply appropriate risk metrics for position limits. Alongside these measures, SEBI mandated brokers to show a risk disclosure stating that “9 out of 10 Individual traders made losses in F&O in FY22” when users log in.

Budget 2026 adds a direct tax cost from April 1

The Union Budget 2026-27 proposed higher STT on derivatives, and the revised rates apply to transactions entered into on or after April 1, 2026. For options, STT on the sale of an option in securities rises from 0.1 percent to 0.15 percent of the option premium. For options where the contract is exercised, STT rises from 0.125 percent to 0.15 percent of the intrinsic price. For futures, STT on the sale of a future in securities rises from 0.02 percent to 0.05 percent of the traded price. Social media posts have highlighted that this is up to a 50 percent hike on key options STT and a 150 percent hike on futures STT. The government’s stated direction is to curb excessive retail speculation rather than block market access outright. The Income Tax department clarified in discussion that the higher levy applies only to futures and options, while other STT rates remain unchanged.

The data point retail traders are sharing most

Retail participation in equity derivatives fell in FY26, which many traders online describe as the first decline in nearly a decade. One set of widely cited numbers puts individual traders at about 87.5 lakh in FY26. Another government-cited set shows unique individual investors declining to 78.60 lakh in FY26 from 98.10 lakh in FY25. A separate comparison mentioned in the same debate puts individual participation at around 87.5 lakh in FY26 versus 106.2 lakh in FY25. Despite differences across reported datasets, the direction is consistent across sources: fewer unique individuals traded. Commentary also points out that around 99 percent of individual investors participated in options trading. Many of them traded only options rather than futures. This matters because several of SEBI’s interventions and the new STT rates directly affect options activity.

Volumes and turnover: a cooler tape in FY26

Options trading volumes in India fell 51 percent in FY26, according to the context being shared. This drop is being linked directly to SEBI’s tighter derivatives rules. Total F&O turnover stood at ₹202 lakh crore in FY26, compared with ₹213 lakh crore in FY25. The turnover change looks modest relative to the reported options volume decline, which traders see as a sign that activity shifted rather than vanished. Some market participants expect the mix to tilt away from short-dated retail-heavy strategies. Others expect professional and institutional participation to take a larger share as compliance and cost burdens rise. A key theme in online discussions is that expiry-day and weekly products were central to the retail surge and therefore central to the cooldown. The policy intent, as described, is to reduce excessive speculative trading while protecting retail investors.

Losses fell in aggregate, but per-person losses stayed high

Government data cited in a Rajya Sabha reply shows aggregate net losses of individuals in equity derivatives declined in 2025-26. Net losses fell to ₹91,685 crore in FY26 from ₹1,11,788 crore in FY25. That looks like an improvement of about 18 percent in aggregate outcomes. However, the same discussion notes that the average loss per individual trader increased even as total losses fell. The simplest explanation offered is compositional: fewer people traded, and those who continued may have taken larger risk. SEBI’s stated objective in the policy framing was to curb speculation and protect retail investors. The risk disclosure message about loss rates has also become a recurring reference point for brokers and traders.

Why small traders say they were hit first

Multiple posts and summaries argue that small retail traders with low turnover were most affected. They point to stricter position limits and higher weekly expiry constraints. They also cite higher option premium funding needs after upfront premium collection was introduced. Brokerage and execution friction are also mentioned as practical barriers when contracts are larger. The contract size increase in index derivatives is frequently described as raising the minimum capital needed to trade. Intraday monitoring of position limits and expiry-day rule changes are seen as reducing flexibility for frequent traders. Traders also expect costs to rise further from April 1 because of the higher STT. The combined effect, in this framing, is fewer casual participants and a market skewed toward those with higher risk capacity.

STT collections and what they signal about activity

STT from F&O trades jumped to ₹27,695 crore in FY26 from ₹6,634 crore in FY22, as per the cited data. Options accounted for ₹19,802 crore of the FY26 STT collection. Futures contributed ₹7,893 crore in FY26. These figures are being used in debates to argue that the derivatives boom had become a meaningful tax base. Another datapoint highlighted in the policy discussion is how quickly retail presence grew in index options. The share of individual investor transactions in index options rose from ₹2 for every ₹100 traded in FY17-18 to ₹41 for every ₹100 traded in FY23-24. Against this backdrop, higher STT is being interpreted as a lever to cool excess demand. It also reinforces why the April 1 effective date is being watched closely by active traders.

What changes on April 1, 2026: key rates and datapoints

The table below summarises the specific STT rate changes and the FY25-FY26 market indicators being discussed. It reflects only the rates and numbers cited in the shared context. Traders are focusing on how these rates apply to each sell-side derivatives transaction category. The broader point is that per-trade costs rise even if strategies and market direction do not change. That makes cost-sensitive, high-frequency options strategies more exposed. Market participants are also weighing the interaction between higher STT and SEBI’s earlier risk and product changes. Together, these define a new baseline for retail participation in F&O. Whether the market stabilises at a lower retail share is now a core question.

Debate shifts to eligibility filters and who should trade

The tax-and-regulation push has also triggered a public debate on how to protect vulnerable investors. NSE Managing Director and CEO Ashishkumar Chauhan has argued that taxing derivatives more heavily cannot prevent small investors from trading. He proposed minimum qualifying criteria for participation in the F&O segment. In public comments cited in the discussion, he suggested eligibility could be linked to an investor’s tax-paying capacity. The argument is that a calibrated qualification filter could be more precise than a blunt tax hike. Others counter that taxes and margin rules are simple to enforce and apply uniformly. What is clear from the FY26 data shared is that participation has already fallen sharply after the combined tightening. The next phase of the debate is likely to focus on market access versus investor protection, with April 1 implementation acting as a key milestone.
