STT Hike in Budget: How does it impact F&O traders

With the rise in retail participation in the futures and options trading and growing speculation in the market, the government made two major hikes in STT on F&O trades in the last two years in order to protect the interest of retail traders.

First there was ~60% F&O STT increase made in Budget 2024 and the second, and most recent, hike in STT was announced in Budget 2026 between 50-150% on options and futures.

Here are the latest STT rates on F&O transactions:

The recent hike in STT rates in the budget will significantly increase the costs for traders. For instance, consider a trader dealing in futures with a contract value of ₹15,00,000.

Here’s how it looks:

Earlier, at an STT rate of 0.02%, the tax payable would have been ₹300. With the revised rate of 0.05%, the STT now increases to ₹750. That’s a whopping 150% increase of ₹450 per contract, excluding brokerage, GST, and exchange charges — directly affecting the trader’s net profitability.

If a trader executes 25 such contracts in a day, the total STT outgo alone would amount to ₹18,750, making transaction costs a far more meaningful factor in overall returns.

At first glance, the steady rise in Securities Transaction Tax feels contradictory.

STT came into effect in October 2004. At that time, the government had removed long-term capital gains (LTCG) tax on listed equities, which means the investor had to pay zero tax on any long term capital gains made. STT acted as a replacement revenue mechanism, a small tax on every transaction instead of taxing gains later.

Over time, LTCG tax was reintroduced in 2018, but STT remained. And now it’s being raised again in Budget 2026!

To understand the hikes, you have to look at participation trends.

Policymakers have been explicit. In post budget commentary, officials framed the STT hike as a way to "bring discipline to speculative volume" and "align the tax regime with long-term capital formation goals."

From FY22 to FY25, the number of retail participants in derivatives markets more than doubled, growing over 120%, from roughly 45 lakh traders to nearly 1 crore. And yet, SEBI data consistently shows that over 90% of these traders lose money.

The government's discomfort is understandable. A derivatives driven frenzy that results in widespread retail household losses creates a political and social problem, even if it doesn't immediately create systemic financial risk.

Rather than imposing hard bans or aggressive compliance restrictions, policymakers are nudging through price signals making speculation incrementally more expensive. This is what economists call a behavioural tax.

In hindsight, the new hike is projected to add approximately ₹10,000 crore to government revenue in FY27. On the surface, that sounds like a meaningful fiscal contribution.

But here is the part worth sitting with: this money does not circulate back into the market ecosystem. It does not fund market infrastructure, investor education, or exchange development. It goes into the government's consolidated fund; a general purpose pool.

That ₹10,000 crore is extracted from market participants, many of whom are already operating at a loss. Every rupee of STT paid by a losing trader is money that depletes their remaining capital, making recovery harder. The SEBI data, in the table below, shows that the net losses of individual traders widened by 41% in fiscal 2025 to ₹1.05 lakh crore.

And if the hike was truly to curb speculative retail trading, then this alone will compress collections.

Only time can tell but if history taught us anything, speculation is often psychological before it is financial.

Yes, some low-conviction trades will become unviable. Traders operating on thin profitability may find their strategies no longer work. A fraction of capital may move toward equities, mutual funds, or passive investing. But speculative markets are not purely math-driven. For traders chasing outsized gains, marginal cost increases rarely alter behaviour decisively. An extra ₹3,000 per crore on futures is unlikely to deter someone motivated by the possibility of a large win.

This brings us to the harder conversation. If over 90% of retail derivatives traders are losing money, is transaction cost really the core issue? Most F&O losses stem from leverage mismanagement, poor position sizing, misunderstanding of time decay, and underestimation of tail risk. STT may increase friction, but it does not correct structural weaknesses in trading behaviour.

Taken together, the message is clear. Policymakers are increasingly uncomfortable with the scale of retail-driven derivatives speculation.They prefer fiscal nudges over outright bans. And if this approach produces even partial behavioural moderation, future interventions are likely to follow the same path, incremental cost increases rather than hard restrictions.

1. What does the STT hike in Budget 2026 mean for traders?
The 2026 Budget raises STT on F&O only, and does not change the STT rates for cash equity (delivery or intraday). For active F&O traders, this means higher friction on every sell-side trade, directly impacting high-turnover strategies.

2. What is the STT hike date?
The revised STT rates announced in Budget 2026 are effective from April 1, 2026. Trades executed from this date onward will attract the higher STT rates in the derivatives segment.

3. What are the new STT charges after the STT hike in Budget 2026?
From April 1, 2026, the new STT charges apply primarily to the derivatives segment. The STT on equity futures (sell side) has been increased to 0.05% from the earlier 0.02%, while the STT on options (sell side, calculated on premium value) has been raised to 0.15% from 0.10%. The STT rates for equity delivery and intraday trades remain unchanged.

4. Can STT be claimed as a deduction in income tax?
For traders who treat trading as a business (business income), STT can be claimed as a business expense. However, for investors reporting capital gains, STT cannot be deducted from capital gains for tax calculation purposes.

5. Will the STT hike increase my brokerage?
Brokerage is separate from STT. Your broker may charge the same brokerage, but the total transaction cost will rise because STT is higher on F&O trades.
