The growth of eight crucial infrastructure sectors in India has decelerated to a 15-month low, registering a mere 3.6 percent increase in January. This downturn is attributed to underperforming sectors such as refinery products, fertiliser, steel, and electricity, as per official data released on Thursday.


In comparison, the growth rate of these core sectors stood at 4.9 percent in December, marking a significant decline. January 2023 witnessed a notably higher growth rate at 9.7 percent, indicating a substantial decrease in growth over the past year.


This recent dip marks the lowest growth rate since October 2022 when it reached a mere 0.9 percent. Cumulatively, the growth rate for April-January 2022-23 period slowed to 7.7 percent, down from 8.3 percent in the previous year.


Among the sectors, refinery products and fertiliser experienced negative growth, while coal, steel, and electricity production saw a deceleration in growth. However, crude oil, natural gas, and cement production managed to record positive growth rates in January.


These eight core sectors collectively contribute 40.27 per cent to the country's Index of Industrial Production (IIP), highlighting their significant impact on the nation's industrial output.
