Core inflation in June 2014
NBP data: In June, inflation net of food and energy prices amounted to 1.0% (y/y) and was 0.2 pp. higher than in May. The CPI index in June stood at 0.3% (y/y).
On 16 July, Narodowy Bank Polski posted data on June 2014 core inflation indices. In year-on year terms, inflation:
- excluding administered (state-controlled) prices, amounted to -0.1%; against the -0.2% seen the previous month;
- excluding the most volatile prices, was at 0.3%, the same level as in May;
- net of food and energy prices, reached 1.0%, a rise of 0.2 pp. on May;
- the so-called trimmed mean (excluding the impact of 15% of the price basket characterised by the highest and lowest growth rates), was running at 0.5%, the same rate as the month before.
The CPI index, announced by GUS on 15 July, stood at 0.3% y/y, against 0.2% in in May.
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 only shows average price movement across the whole broad basket of consumer goods. By calculating 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 forecast 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 most frequently used by analysts is inflation excluding 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. Also food prices are largely dependent on, among other things, the weather and conditions prevailing in the domestic and worldwide agricultural market.
