Inflation explained: What lies behind it and what lies ahead?
Understanding inflation dynamics requires an understanding of the underlying concept and how it is measured. Inflation is defined as a process of continuously rising prices and falling purchasing power. In other words, a general and broad-based increase in the price of goods and services over an extended period. The main objective of central banks is to keep prices stable, to preserve the integrity and purchasing power of people's money. The most common inflation indicator measures the average change in the price of a basket of consumer goods and services over time. The closest approximation of what people intuitively understand by the term inflation is the change in their cost of living. The Harmonised Indicator for Consumer Prices (HICP), against which the European Central Bank (ECB) assesses the achievement of its price stability objective, is based on this concept. Highlighting the principles of optionality, gradualism and flexibility in a recent speech, ECB President Christine Lagarde reflected upon the current uncertainty. After several years of inflation rates significantly below the inflation target, the ECB is now facing consumer price increases not seen since the launch of the euro. In February 2022, inflation rates hit an annual rate of 5.9 % in the euro area and 6.2 % in the EU. The Russian war on Ukraine is now likely to cause inflation to increase further, with underlying price pressure broadening and lingering supply-side bottlenecks.
