India's economy grew by 6.3% in the September quarter, down from 13.5% in the preceding quarter and 8.4% a year ago.

The manufacturing and mining sectors contracted and contributed to the slowing of the GDP. While manufacturing fell 4.3%, the mining sector recorded a 2.8% decline in growth.

Agricultural output rose 4.6% while the construction sector saw a 6.6% annual increase in activity.

"Real GDP or GDP at constant (2011-12) prices in Q2FY23 is estimated at Rs 38.17 trillion, as against Rs 35.89 trillion in Q2FY22, showing a growth of 6.3% as compared to 8.4% in Q2FY22," the ministry of statistics and programme implementation (MoSPI) said on Wednesday.

Nominal growth rate was 16.2% year-on-year.

"Nominal GDP or GDP at current prices in Q2FY23 is estimated at Rs 65.31 trillion as against Rs 56.2 trillion in Q2 2021-22, showing a growth of 16.2% as compared to 19% in Q2FY22," it added.

For the first half of FY23, the GDP growth rate was 9.7% versus 13.7% a year ago.

"The Q2 FY2023 GDP growth of 6.3% came in similar to our estimate of 6.5%, even as the GVA rise of 5.6% trailed our forecast (6.3%) by a wide margin, led by an unexpected contraction in manufacturing that seems to reflect the impact of high input prices on margins in certain sectors," said Aditi Nayar, chief economist at ICRA.

Private consumption expenditure and gross fixed capital formation increased. Said Nayar, “GDP growth was boosted by the performance of private consumption expenditure and gross fixed capital formation, whereas government expenditure displayed a discouraging contraction in Q2 FY2023, on account of the modest de-growth in the Centre's non-interest revenue expenditure."

Earlier this month, in an article published in the Reserve Bank of India (RBI) bulletin, the GDP growth was pegged at 6.1-6.3% in the second quarter of this fiscal year.

China reported an economic growth rate of 3.9% in the July-September quarter of 2022.
