At a time when global markets are witnessing high volatility due to geopolitical uncertainties, the hike in securities transaction tax (STT) on derivatives trades hit investor sentiment on Dalal Street on the Budget day. This in turn led to a sharp sell-off that pulled the sensex down by nearly 1,500 points—its biggest points loss on a Budget day—to close at 80,773 points. The sell-off also left investors poorer by Rs 9.4 lakh crore, the biggest Budget day loss in BSE’s market capitalisation.The day’s trading was marked by high volatility. The sensex rallied over 400 points as FM started her speech, fell about 1,100 points after the STT hike proposal was announced, partially recovered by mid-session to trade 600 points down on the day and then sold-off to close below the 81K mark for the first time in four months.On the NSE, Nifty too treaded a similar path to close 495 points (2%) lower at 24,825 points. Fund managers and market players feel the day’s sell-off was overdone, compounded by the absence of most institutional players since it was a Sunday. “The market’s reaction (to the hike in STT rates) was a bit overdone, although the decision itself was unexpected,” said Taher Badshah, President & Chief Investment Officer, Invesco Mutual Fund. “I think markets should settle down in 2-3 days.” Badshah said the Budget was in line with govt’s set path of the past few years, showing a conservative approach to setting targets.“The revenue and expenditure targets for FY27 are achievable. And since the rate of inflation is lower now, the nominal GDP growth rate of 10% may turn out to be on the higher side as inflation normalises during the year,” the top fund manager said. In Sunday’s market, of the 30 sensex stocks, 26 closed in the red. Among index constituents, Reliance Industries, SBI and ICICI Bank contributed the most to the day’s loss. Buying in software services majors Infosys and TCS cushioned the slide. In all, 2,444 stocks closed in the red compared to 1,699 that closed in the green, BSE data showed.STT hike aimed at curbing F&O speculation The decision to raise securities transaction tax (STT) for trading in equity derivatives means trading futures & options (F&O) will be more expensive from April 1. STT on futures trading rises from 0.02% to 0.05% now, and on options premium and exercise of options to 0.15% from 0.1% and 0.125% respectively. This could more than double statutory costs of trading F&O contracts.While the move is to curb excessive speculation by retail traders who mostly suffer losses, investors sold stocks of those companies that derive a large portion of their turnover from this segment. Stock price of Angel One crashed nearly 9%, BSE crashed 8.1%, Billionbrains Garage Ventures that runs the Groww trading platform, lost 5.1% and Nuvama Wealth Management lost 7.3%. STT hike follows a Sebi survey that showed that 91% of the retail investors lost money in the F&O market with average loss per investor surpassing Rs 1 lakh per year. Institutional and some high net worth players took home most of the profits from the segment.18% GST on brokerage for FPIs removedThe Budget proposed to do away with 18% GST charged on the brokerage that foreign portfolio investors pay in India. Among the host of changes to the GST laws that the finance minister proposed, one was abolishing clause (b) of sub-section (8) of section 13 of the Integrated Goods and Services Tax Act, 2017. This is being “omitted so as to provide that the place of supply for ‘intermediary services’ will be determined as per the default provision under section 13(2) of the IGST Act,” the Budget proposal said.
