India's GDP growth slowing; official data counter-intuitive

Indian economy has been losing momentum since middle of financial year 2014-15, a new study says, citing corporate results and 'real economic indicators', while questioning the 'counter-intuitive' official GDP data. 
It also said that a region-wise analysis shows that the southern part of the country has been witnessing faster economic growth than the North, in contrast to the trend shown by the official data. 
However, it is Middle India that is growing the fastest, as per the Regional Keqiang Index (RKI) developed by leading financial services and investment research firm Ambit Capital. 
According to Central Statistics Office (CSO) data, GDP growth 'accelerated' in fiscal 2015-16 as against 2014-15, Indian news agency (PTI) reported. 
The Ambit Capital report noted that "corporate results as well as the range of alternative tools we have developed to track the health of the real economy, however, suggest that the Indian economy has been losing momentum since mid-FY15". 
It further added that "for 2015-16, the CSO's data shows that GDP growth was recorded at 7.6%, implying that GDP growth 'accelerated' from 7.2% in 2014-15. 
However, this once again makes little sense as 9 of 14 real economy indicators (supplied by industrial bodies/regulators as against the government) decelerated in fiscal 2015-16". 
The report termed the state level GDP data as "dodgy", and said that its "annual-RKI suggests that South India has been outperforming the North on the economic growth front", and going by the quarterly-RKI, "Middle India has been the strongest performer". 
The Keqiang Index (IKI) comprises 'real' economy indicators. IKI consists of four indicators, namely motor vehicle sales, capital goods imports, power demand, and cargo handled at airports. 
This indicator confirms our view that the Indian economy is undergoing a pronounced slowdown, the report said. 
"If the new GDP series did not exist and if we use our IKI to estimate the pace of growth in the real economy as per the old GDP series, our GDP estimate for the second quarter of 2015-16 would be 6.2% (as against 7.7% on the new GDP series) and for the third quarter of 2015-16 it would be 5.4% (as against 7.3% on the new series)," it added.
