STT hike more for deterrence purposes rather than revenue: FM

Finance Minister Nirmala Sitharaman said the increase in the Securities Transaction Tax (STT) on F&O trades was "more for deterrence purposes rather than revenue purposes". However, she added that the move is not like "one pill that will solve speculative tendencies". The Budget raised STT on futures from 0.02% to 0.05% and on options from 0.1% to 0.15%.
