Core Inflation in October 2013

Date: 15-11-2013

NBP data: In October, inflation net of food and energy prices amounted to 1.4% (y/y), rising by 0.1 percentage point on its September level. The other three core inflation indices declined.

On 15 November, Narodowy Bank Polski released information on core inflation measures in October 2013. In year-on-year terms inflation:

  • excluding administered (state-controlled) prices reached 0.5%, as against 0.7 % a month before;
  • excluding the most volatile prices amounted to 1.5%, as against 1.6% in September;
  • net of food and energy prices increased to 1.4%, as against 1.3% at the end of September;
  • the so-called trimmed mean (excluding the impact of 15% of the price basket characterised by the lowest and highest growth rates) dropped by 0.5%, as against 0.8% in September.

The CPI (consumer inflation) index, announced by GUS on 14 November amounted to 0.8% (y/y) in October, as against 1.0% in September.

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 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, the 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 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. Also food prices are largely dependent on, among other things, the weather and conditions prevailing in the domestic and worldwide agricultural market.
