The primary objective of Eurosystem monetary policy is to maintain price stability, de…ned
as an annual increase in the HICP below two percent.1 Because of the lags in the e¤ects
of monetary-policy actions on aggregate demand and in‡ation, monetary-policy actions cannot
a¤ect current in‡ation and output, nor in‡ation or output in the near future. A rough benchmark
is that monetary policy a¤ects output in about a year and in‡ation in about two years. Therefore,
Eurosystem monetary policy has to be guided by in‡ation forecasts about two years ahead.
As discussed further in Svensson [11], for successful policy, the Eurosystem must construct
conditional in‡ation forecasts. These forecasts should depend on all relevant information, in-
cluding the Eurosystem’s view of the transmission mechanism for monetary policy, its view of
the current economic and monetary situation within and outside the Euro area, information
about current and future …scal policy, private-sector in‡ation expectations, etc. In particular,
the forecasts should be contingent on alternative paths for the monetary-policy instrument rate,
that is, the interest rate on the main re…nancing operations. This way, the Eurosystem can select
an instrument-rate path, for which the conditional in‡ation forecast about two years ahead is
in line with the de…nition of price stability, and then set the instrument rate accordingly.
