Price stability is where prices change by a small and consistent amount. In other words, monetary policy maintains low and stable inflation. To do this they use interest rates set by the Monetary Policy authority.
A situation in which the average level of prices is neither moving up nor down. Because of measurement error, price stability deemed consistent with a small (in the range 2-3 per cent) rise in the consumer price index.
As a central bank, the Riksbank is responsible for monetary policy. The objective of monetary policy is price stability, i.e. to maintain the average rate of price increases (inflation) at a low, stable level. More specifically the aim is to keep inflation at 2 per cent, with a permitted deviation of +/- 1 percentage point.
