Can central bank communication effectively guide the monetary policy expectation of the public?

Central bank communication helps to optimize monetary policy. Therefore, it is essential to study whether central bank communication can effectively guide expectations via various communication methods. We study central bank communication in China using the events collected from its official websites and social media, and we divide them into formal and informal communications. We use the high-frequency quotation data of treasury bonds to identify monetary policy surprise caused by communication, which is measured by the target and path surprise. Then, we evaluate the forward-looking and backward-looking effectiveness of central bank communications. We show that central bank communications can help guide public expectations, but different topics and different forms of communication have heterogeneous effects. Forward guidance carries both potential benefits and drawbacks. It is worth noting that China's current central bank communications may have certain potential to be improved.
