Indian shares tumbled on Friday as the long-term capital gains tax on equities investments dampened sentiment, while bonds slid for a second consecutive session on worries the central bank would become more hawkish on inflation.
The weak sentiment came a day after the government unveiled its budget for the year starting in April that raised spending for rural sectors and healthcare, widening the fiscal deficit target to 3.3 percent of gross domestic product from the previous 3.0 percent.
Investors worried that higher spending and the government's move to raise minimum support prices for crops could lead to higher retail prices at a time when consumer price inflation has already hit a 17-month high of 5.21 percent, well above the Reserve Bank of India's target of 4 percent.
That is leading to fears the RBI could adopt a more hawkish tone at its policy review on Feb. 6-7, although it is widely expected to keep rates on hold.
The government also unveiled a 10 percent tax on long-term capital gains in equity markets.
"Long-term capital gains tax on equities is not welcomed by the markets and fiscal slippage is another reason that's driving the markets down," said Neeraj Dewan, director, Quantum Securities.
