The Swiss National Bank usually announces its interest rate policy on a quarterly basis as part of its Monetary Policy Assessment. However, emergency measures can be announced at any time.
The aim of the SNB's monetary policy is to ensure price stability in the medium and long term. By keeping prices stable (2 percent annual inflation rate), the SNB seeks to create an environment in which the economy can fully exploit its production potential. The Bank is required to set its policy to meet the needs of the Swiss economy as a whole rather than the interests of individual regions or industries.
The SNB has traditionally implemented its monetary policy by fixing a target range of 1.0 percentage points at the level deemed appropriate for the three-month Swiss franc Libor. The Bank has then normally sought to hold the rate around the middle of that corridor. However, as a result of strong capital inflows into the local currency prompted by the 2008/09 global downturn, this objective range has been both narrowed and reduced to just 0.0 - 0.25 percent, with a point target of 0.0 percent. In fact, since September 2011 the thrust of policy has been determined largely by the SNB's expressed aim of preventing the CHF strengthening beneath a CHF1.20 floor versus the euro.
The Swiss National Bank publishes its monetary policy assessments on a quarterly basis in March, June, September and December. In these reports it describes the current monetary environment and formulates its monetary policy intentions for the following quarter. It also provides inflation forecasts which help financial markets to formulate of where monetary policy might be headed. Twice a year -- in June and in December -- the Bank holds a media conference. At that time, the Governing Board provides information about the economic situation and comments on its monetary policy.
