Contributed by both food and non-food inflation, headline inflation, as measured by the year-on-year change in the Colombo Consumers’ Price Index (CCPI, 2013=100), increased to 5.5 per cent in January 2017 from 4.5 per cent in December 2016. Core inflation, based on CCPI, also accelerated to 7.0 per cent in January 2017 from 5.8 per cent in December 2016. Headline inflation and core inflation, based on the National Consumer Price Index (NCPI, 2013=100), which is available with a time lag, also reflected an upward trend in December 2016, recording 4.2 per cent and 6.7 per cent, respectively, on a year-on-year basis. In spite of the increase in inflation in recent times, which is mainly attributed to the impact of tax adjustments and the adverse weather conditions, inflation is projected to remain in mid-single digit levels, on average during the year supported by appropriate supply side and demand management policies.

Inflation, as measured by the change in the National Consumer Price Index (NCPI) (2013=100), which is compiled by the Department of Census and Statistics, increased marginally to 4.2 per cent in December 2016 from 4.1 per cent in November 2016, on year-on-year basis. Both Food and Non-food categories contributed towards the year-on-year inflation in December 2016.

The change in the NCPI measured on an annual average basis remained unchanged from last month at 4.0 per cent in December 2016.
