We examine how written and oral central bank communications affect the level and volatility of interest rates. We use detailed daily data on the Czech central bank's communication in 2007-2012.
We find that financial markets respond to central bank communication. Short-term interest rates rise if the bank communicates that economic conditions are good.
The results suggest that written communication, but not oral communication, decreases the volatility of both short-term and long-term interest rates. The timing of communication has a key role, as comments made closer to the monetary policy meeting have a bigger calming effect on the markets.
All in all, our results point to the importance of well-designed communication for reducing noise in the financial markets.
