India hikes STT and margin rules April 1
India’s new rules that kick in April 1 raise the Securities Transaction Tax—up to 150% on futures and 50% on options—and require 100% collateral for bank guarantees in margin trading. Brokers are selectively adjusting fees, and the near-term effect should be reduced derivatives turnover and higher breakevens for futures traders across global flows. (economictimes.indiatimes.com)
Union Budget 2026, presented by Finance Minister Nirmala Sitharaman on February 1, 2026, formally proposed the changes to Securities Transaction Tax that apply to the derivatives segment. (economictimes.indiatimes.com) The Budget set specific STT levels for derivatives, moving futures STT to 0.05% and taking options premium and exercise levies to 0.15%. (cnbctv18.com) The Reserve Bank of India issued the “Commercial Banks – Credit Facilities Amendment Directions, 2026” on February 13, 2026, directing banks to extend credit to SEBI‑regulated brokers only on a fully secured basis. (rbi.org.in) On March 30, 2026 the RBI published a revised set of those Amendment Directions that states the provisions will come into force from July 1, 2026, or earlier if a bank decides to implement them in entirety. (rbi.org.in) The RBI framework explicitly tightened bank‑guarantee rules by requiring higher collateral for guarantees (industry reports cite a 50% collateral floor with a 25% minimum in cash for certain guarantees) and barred banks from funding proprietary trading. (businesstoday.in) Capital‑market stocks reacted sharply to the Budget and regulatory moves, with broking and exchange names such as BSE, Angel One and Groww plunging up to around 10–15% intraday on the Budget announcement. (moneycontrol.com) Broker and sell‑side impact estimates vary: HDFC Securities’ MD & CEO Dhiraj Relli warned derivatives volumes could fall roughly 20–30% including proprietary flows, while Jefferies models suggested that if ~50% of prop trading (ex‑HFT) were affected it could shave about 10–12% off options turnover. (moneycontrol.com 1) (moneycontrol.com 2) (financialexpress.com) Execution‑level economics changed materially in published dealer math: analysts estimate the STT move raises round‑trip costs for standard index futures by the equivalent of roughly 10–12 index points on the exit leg, producing new breakeven thresholds in the 20–25‑point range after other fees are included.
