The role of central bank communication in inflation-targeting Eastern European emerging economies

In this paper, we analyze whether central bank communication can be an additional tool to provide guidance on monetary policy, drive private agents’ inflation expectations and financial asset prices in the main countries of Central and Eastern Europe. By applying natural language processing techniques to monetary policy statements and minutes, we first derive a series of salient topics on which central bank communications focused over the last two decades, and then develop indices of tone to gauge their respective degrees of hawkishness (dovishness) about the economic outlook. By using these indices in an econometric set-up, we find that a more hawkish (dovish) tone – reflecting a more positive (negative) assessment of the economic outlook – anticipates a more restrictive (accommodative) monetary policy decision, raises (lowers) short-term inflation expectations of private sector agents, increases (reduces) market interest rates across different maturities, and drives share prices down (up). Overall, our analysis suggests that communication may be a complementary and effective monetary policy tool available to central banks in emerging economies.
