{{/usCountry}}The finance minister's announcement means that the Securities Transaction Tax (STT) charged on futures trading has been increased to 0.05 per cent from 0.02 per cent of the transaction value, making futures trades slightly more expensive.
STT is a government tax applied to market transactions, so this hike directly raises the cost for traders, especially those who trade frequently or in large volumes.
While the increase may help curb excessive short-term speculation and boost tax revenue, it also reduces net profits for active futures traders.
The Budget 2026 focuses on three ‘kartavyas’ or duties, Nirmala Sitharaman began her speech by saying. The three kartavyas she said are: Accelerate and sustain economic growth along with building resilience to volatile global dynamics; fulfill spirations of our people and build their capacity; and ensure that every family, community, region and sector has access to resources, amenities and opportunities.
An STT Options hike means the government has increased the Securities Transaction Tax charged on Options trades, which raises the cost of buying or selling options in the stock market.
This directly impacts Options traders-especially frequent and short-term traders-by reducing their net profits per trade.
