According to a report by Deutsche Bank, tightness in cement markets could be achieved well ahead of the cyclical upturn estimated in late 2013-14.The report expects tightness in the market in the immediate future because of the absence of a strong logistic supply movement and the resultant difficulty in inter-regional cement and clinker shipments.Cement as a commodity is extremely voluminous and among the lowest value-added, so logistical constraints in both intermediate supplies and finished goods supplies have the power to result in supply disruptions and plant closures, the report said.Because of the anticipated tightness in the market, the cement industry may see a cyclical upturn in the near future, the report said.Currently, Railways account for as much as 45 per cent of cement movement and 70 per cent of clinker movement, the report said. Volumes have grown at around 10 per cent over the last three quarters, despite slowing GDP growth, and thus suggesting a lower correlation with GDP, it said.
