Benefits of price stability

The objective of price stability refers to the general level of prices in the economy. It implies avoiding both prolonged inflation and deflation. Price stability contributes to achieving high levels of economic activity and employment by

  • improving the transparency of the price mechanism. Under price stability people can recognise changes in relative prices (i.e. prices between different goods), without being confused by changes in the overall price level. This allows them to make well-informed consumption and investment decisions and to allocate resources more efficiently;
  • reducing inflation risk premia in interest rates (i.e. compensation creditors ask for the risks associated with holding nominal assets). This reduces real interest rates and increases incentives to invest;
  • avoiding unproductive activities to hedge against the negative impact of inflation or deflation;
  • reducing distortions of inflation or deflation, which can exacerbate the distortionary impact on economic behaviour of tax and social security systems;
  • preventing an arbitrary redistribution of wealth and income as a result of unexpected inflation or deflation;
  • and contributing to financial stability.

While the Treaty clearly establishes the maintenance of price stability as the primary objective of the ECB, it does not give a precise definition of what is meant by price stability.

Quantitative definition of price stability

The ECB’s Governing Council has defined price stability as "a year-on-year increase in the Harmonised Index of Consumer Prices (HICP) for the euro area of below 2%. Price stability is to be maintained over the medium term".

The Governing Council has also clarified that, in the pursuit of price stability, it aims to maintain inflation rates below, but close to, 2% over the medium term.
