Union Budget 2026 Delivers a Blow to F&O Traders with STT Hike
In a significant move impacting the capital markets, Finance Minister Nirmala Sitharaman, during the Union Budget 2026 presentation on February 1, announced a substantial increase in the Securities Transaction Tax (STT) on futures and options (F&O) contracts. The proposal, aimed at curbing speculative trading and protecting retail investors, will make derivative trading more expensive, directly affecting the profitability of active traders and potentially reducing market volumes. The announcement triggered an immediate negative reaction in the market, with shares of brokerage firms and stock exchanges like BSE Ltd. falling by up to 10%.
Understanding the New STT Structure
The budget proposes a sharp revision in STT rates for the derivatives segment. This tax is levied on the value of transactions at the time of the trade, irrespective of whether the trader makes a profit or loss. The changes are designed to increase the cost of executing trades, thereby discouraging high-frequency, speculative activity.
Here is a summary of the proposed changes to STT rates:
| Instrument | Previous STT Rate | Proposed STT Rate (Budget 2026) |
|---|
| Futures | 0.02% | 0.05% |
| Options Premium | 0.1% | 0.15% |
| Options Exercise | 0.125% | 0.15% |
These new rates are expected to be effective from April 1, 2026.
The Real-World Cost for Traders
The proposed hike translates into a tangible increase in transaction costs. For futures traders, the STT has more than doubled. For instance, on a Nifty futures contract with a notional value of ₹2,00,000, the STT payable would increase from ₹40 (at 0.02%) to ₹100 (at 0.05%). This represents an additional cost of ₹60 per lot.
Similarly, for options traders, the cost on the premium has increased by 50%. On an options contract with a premium value of ₹10,000, the STT would rise from ₹10 (at 0.1%) to ₹15 (at 0.15%). While these amounts may seem small per transaction, they accumulate significantly for active traders, scalpers, and high-frequency trading firms that execute hundreds or thousands of trades daily.
Government's Rationale: Curbing Speculation
The Finance Minister's speech indicated that the primary objective behind the STT hike is to moderate the frenzy in the F&O segment and safeguard retail investors. This aligns with recent concerns raised by market regulator SEBI. A 2025 SEBI study revealed that over 90% of individual traders in the F&O market incurred net losses. The government believes that by increasing the cost of trading, it can deter excessive speculation and reduce market volatility, making the ecosystem safer for less-informed participants.
Shripal Shah, MD & CEO of Kotak Securities, noted, "The steep increase in STT on futures and options... is likely to raise impact costs for traders, hedgers, and arbitrageurs. This could cool derivative activity and lead to a reduction in volumes. The intent appears to be volume moderation rather than revenue maximisation."
Industry's Disappointment and Historical Context
The move comes as a disappointment to the capital market industry, which had been advocating for a reduction in STT. In pre-budget consultations held in November 2025, market participants had requested a lower STT on cash market trades to restore balance with the derivatives segment and improve market depth.
STT was originally introduced in 2004 to replace the long-term capital gains (LTCG) tax. However, the Union Budget 2018 reintroduced LTCG tax on listed equities, while STT remained in place, effectively increasing the overall tax burden on investors. This latest hike further compounds the cost pressures on market participants.
Impact on Brokerages and Market Liquidity
The immediate fallout was visible in the stock prices of listed brokerages like Angel One and exchanges such as BSE, which rely on trading volumes for revenue. A potential reduction in trading activity could directly impact their financial performance. Zerodha co-founder Nithin Kamath has previously pointed out that STT hikes, like the one in 2024, can lead to lower-than-projected tax collections if they significantly dampen trading volumes. He argued that the government might have collected more tax revenue with lower STT rates due to higher participation.
Analysts believe the hike will most severely affect scalpers and arbitrageurs who operate on thin margins. The increased transaction cost could make many of their strategies unviable, potentially leading to a reduction in overall market liquidity.
Conclusion: A New Reality for F&O Traders
The Union Budget 2026 has fundamentally altered the cost dynamics of F&O trading in India. While the government's intention is to promote market stability and protect retail investors, the move will force traders to reassess their strategies. The higher cost structure will likely lead to a moderation in trading volumes and could impact the revenues of the brokerage industry. As the new rates come into effect, all market participants will need to adapt to this new, more expensive trading environment.
