Indian stock markets will implement significant regulatory changes starting April 1, including sharp increases in securities transaction tax on derivatives and stricter collateral requirements for proprietary trading. The securities transaction tax, or STT, will rise by 150% on futures and 50% on options. New Reserve Bank of India rules mandate 100% collateral for bank guarantees in proprietary trading, up from the previous 50%.
From April 1, traders and brokers in Indian stock markets face higher costs due to elevated securities transaction taxes on derivatives. The STT hike targets futures with a 150% increase and options with a 50% rise, reshaping trading dynamics as part of measures announced in the Union Budget 2026. These changes aim to adjust the fiscal framework for derivatives trading amid growing market volumes. These adjustments follow the Union Budget 2026, which introduced the tax modifications to impact stock market participants directly. Meanwhile, the Reserve Bank of India has tightened funding norms, requiring full 100% collateral backing for bank guarantees used in proprietary trading positions. This doubles the previous 50% requirement, limiting leverage for brokers and proprietary desks. Market participants anticipate these rules will influence trading strategies, potentially reducing speculative activity in futures and options segments. The Economic Times first detailed the impending shifts, highlighting effects on daily operations for traders and brokers across exchanges like the National Stock Exchange and BSE.
