Summary

Monetary aggregates have historically been important in Swiss monetary policy. The Swiss National Bank used money growth targets until 1999. The new policy framework introduced in 2000 focuses on an inflation forecast that relies on money growth as an indicator. How useful is money growth for explaining inflation in Switzerland? Using data spanning 1979 to 2007, we estimate a Phillips curve model that incorporates a measure of “trend” money growth and find that it impacts on inflation if one takes the downward shift in nominal interest rates over the sample into account. Including money growth reduces the in-sample forecasting errors by 15%.
