Indian equity markets witnessed a sharp intraday sell-off on Sunday, February 1, after Finance Minister Nirmala Sitharaman announced a significant hike in the Securities Transaction Tax (STT) on derivatives in the Union Budget. Benchmark indices plunged up to 3% during the session before recovering part of the losses to close around 2% lower.
Under the revised structure, STT on futures has been increased to 0.05% from 0.02%, while STT on options transactions has been raised to 0.15% from earlier levels. Announcing the move, Sitharaman said, “I propose to raise the STT on Futures to 0.05% from the present 0.02%. STT on options premium and exercise of options are both proposed to be raised to 0.15% from the present rate.”
The hike significantly raises trading costs. For instance, selling futures worth ₹1 lakh will now attract ₹20 in STT versus ₹12.50 earlier. Similarly, STT on a ₹10,000 options contract sale has risen to ₹10 from ₹6.25
Markets React Sharply
Following the announcement, the BSE Sensex fell 1,547 points (1.88%) to close at 80,722.94, while the Nifty 50 declined 495 points (1.96%) to end at 24,825.45. The broader market saw nearly ₹10 lakh crore wiped off investor wealth in a single session, as total market capitalisation of BSE-listed companies slipped to ₹450 lakh crore from ₹460 lakh crore in the previous session.
What the STT Hike Means for Markets
Market participants believe the STT hike has implications beyond just higher transaction costs. Jimeet Modi, Founder & CEO of SAMCO Group, described the Budget as largely defensive. “On our India Budget Strength Index, this budget scores 4 out of 10. While fiscal discipline is intact, the STT increase weakens India’s global capital-market competitiveness,” he said.
According to Modi, higher derivatives costs could reduce trading volumes, which may spill over into lower liquidity in cash markets. Over time, this could raise liquidity premiums, affect valuation multiples, and influence capital allocation and fundraising decisions.
STT is levied on transactions in equities, futures, and options traded on recognised exchanges. While it improves transparency and compliance, it directly increases trading costs—particularly impacting active traders and derivative participants—thereby reducing post-tax returns.
Why the Correction May Be Short-Lived
Despite the sharp reaction, analysts believe the sell-off was largely technical and driven by an immediate repricing of derivatives strategies. High-frequency traders, arbitrageurs, and short-term participants were quick to unwind positions as costs rose.
Importantly, there has been no deterioration in India’s macroeconomic or earnings outlook.
Aakash Shah, Technical Research Analyst at Choice Equity Broking, noted that long-term foreign investors are unlikely to be deterred. “For long-only, fundamentally driven FPIs, the STT hike is not a deal-breaker. Their decisions depend more on earnings visibility, currency stability, and policy predictability,” he said. While higher costs may reduce tactical flows, sustained foreign investment will hinge on macro stability, rupee movement, and consistency in tax policy.
Structural Positives Remain Intact
The Budget continues to reassure long-term investors, with a fiscal deficit target of 4.3% for FY27 and a record ₹12.2 lakh crore allocation for capital expenditure. These measures reinforce the government’s commitment to infrastructure, manufacturing, and the broader investment cycle.
Prasenjit Paul, Equity Research Analyst at 129 Wealth Fund, said the market reaction was triggered by both the STT hike and changes in buyback taxation. However, he stressed that the Budget remains structurally sound, supported by fiscal consolidation, infrastructure risk guarantees, and asset monetisation aimed at crowding in private capital and sustaining earnings momentum.
Market veterans echoed similar views. Dhiraj Relli, MD & CEO of HDFC Securities, described the fall as a knee-jerk reaction. “Investors should stay invested and focus on sectors with strong earnings visibility. Several supportive provisions in the Budget will play out over time and support growth through FY27,” he said.
Outlook
As markets adjust to the new cost structure, experts expect attention to shift back to earnings growth, government capex momentum, and macro stability. Historically, policy-driven volatility has often been followed by recoveries once short-term disruptions settle.
With fiscal credibility intact, improving access for foreign investors, and a sustained infrastructure push, India’s long-term equity story remains well supported. The recent correction appears to reflect higher derivatives costs rather than any change in the country’s structural growth outlook—suggesting the downturn may indeed prove temporary.
