Core inflation in March 2015
NBP data: in March, inflation net of food and energy prices stood at 0.2% (y/y) and was by 0.2 pp lower than in February. The CPI index in March stood at -1.5% (y/y).
On 16 April 2015, Narodowy Bank Polski posted data on core inflation indices in March 2015. In year-on-year terms, inflation:
- excluding administered (state-controlled) prices amounted to -2.0%, as against -2,1% a month before;
- excluding the most volatile prices decreased to -0.4% from -0.3% observed in February;
- net of food and energy prices, amounted to 0.2%, i.e. 0.2 pp less than in February;
- the so-called 15-percent trimmed mean (excluding the impact of 15% of the price basket characterised by the lowest and the highest growth rates) stood at -0.4%, as against -0.3%, the month before.
The March CPI index, announced by GUS on 15 March 2015, amounted to -1.5% (y/y).
Narodowy Bank Polski computes the four core inflation indices on a monthly basis in order to highlight the nature of inflation developments in Poland. The CPI index shows the average price movement across the whole broad basket of consumer goods. By calculating the core inflation indices we can address price changes in various segments of the basket. Thus, sources of inflation can be identified more precisely, and future trends forecasted more accurately. Furthermore, it can be determined to what degree the observed inflation trend is a lasting phenomenon, and to what extent it is driven by e.g. short-lived price hikes triggered by incidental factors.
The core inflation measure the most frequently used by analysts is inflation net of food and energy prices. It captures movements in prices which are fairly responsive to the central bank's monetary policy. On the other hand, energy prices (including fuel prices) are not set domestically, but determined in the global markets, sometimes as a result of speculation. Food prices are largely dependent on, among other things, the weather and conditions prevailing in the domestic and worldwide agricultural markets.
