Even though India clocked record Q1 GDP growth rate, rising current account deficit (CAD) remains a major concern for the economy, Neelkanth Mishra of Credit Suisse said. \u201cThe fact that we grew at 10.3 percent is not surprising. On a 2-year CAGR basis, the growth is flat. The trend growth is continuing but what worries me is that even at this growth we are running a balance of payment deficit and therefore this growth appears unsustainable and has to slow down,\u201d Neelkanth Mishra, Managing Director and the Credit Suisse India Economist and Strategist told CNBC TV18. Talking about rupee free fall, Neelkanth Mishra said, \u201cAs the rupee weakens and as it translates into higher prices of autos, higher prices of consumer staples, you will see demand starting to slowdown. We have started to see some signs of that." Strong GDP growth numbers for quarter ended June maybe a strong sign but the same can\u2019t be be taken as a strong growth indicator, he added. India posted 8.2 percent GDP growth in April-June quarter of fiscal ending March 2019. It is the fastest the Indian economy has expanded in the nine quarters. In April-June 2017, the GDP growth was recorded at 5.6 percent. The first quarter GDP growth in India is significantly higher than 6.7 percent clocked by China during the corresponding period. \u201cIndia\u2019s GDP for the first quarter this year growing at 8.2% in otherwise an environment of global turmoil represents the potential of New India. Reforms and fiscal prudence are serving us well. India is witnessing an expansion of the neo middle class,\u201d Finance Minister Arun Jaitley had tweeted.
