On the back of robust growth in coal and cement production, the core sector grew by 5.2% in June. The index recovered from a five-month low in May, when it had grown 2.8%.
Data released by the Commerce Ministry on Monday shows that growth in the eight core industries - coal, crude oil, natural gas, refinery products, fertilisers, steel, cement and electricity - had a cumulative growth of 5.4% for the months leading up to June in the current financial year.
The core sectors, which constitute 38% of India's total industrial production, had a lower growth of 2.5% in the same period of the previous year.
The June core sector data represents the last crucial macroeconomic data before the Reserve Bank of India convenes the monetary policy review next week. Rising industrial growth, coupled with high food inflation, might convince RBI to retain the current policy rate of 6.5%.
Given the current situation, RBI might maintain status quo, Madan Sabnavis, Chief Economist at CARE ratings said. He added that the RBI will also take heed of the growing debate over Index of Industrial Production (IIP) numbers not accurately portraying the state of the economy.
