Industrial output growth in the country dipped to 5.5 percent in August, the slowest pace in 15 months and nearly halfof last year. Growth of the manufacturing sector, which accounts for 80 per cent of the factory output, slipped to 5.9 per cent from 10.6 per cent in August last year. Finance Minister Pranab Mukherjee said the trend is disappointing. The poor showing drew immediate calls from the industry against any further increase in key policy rates by the Reserve Bank. The bank is slated to review its monetary policy on the second of next month. India Inc believes the slow growth is due to tight monetary policy that has pushed up interest rates.
