Moody's Investors Service and its Indian affiliate ICRA said India will remain one of the fastest growing major economies globally in 2017, although GDP growth will moderate in the first half of the year, as the economy adjusts after demonetisation India is rated Baa3 positive by Moody's.Moody's also believes that the government will likely achieve its fiscal deficit target of 3.5% of GDP for the current fiscal year ending 31 March 2017, the international rating agency said in a statement on Monday.ICRA expects the country's growth of gross value added at basic prices to remain healthy in 2017, although such growth will ease somewhat to about 6.6% from around 7.0% in 2016, with a likely pick-up in H2 2017, it said."Even after the currency in circulation is replenished, we expect that India's economic growth will stabilize with a lag, while remaining strong," said Aditi Nayar, an ICRA Principal Economist."The adjustment and recovery period could stretch to as much as 2-3 quarters for certain sectors," she said.ICRA said that the focus on digital transactions and the introduction of a goods and services tax (GST) will likely reduce the competitiveness of the unorganised sector. "ICRA therefore anticipates a relatively healthier expansion of the organised sectors in 2017, at the cost of the unorganised sectors," the statement said.
