要約:We empirically examine how complexity of ECB communications affects financial market trading based on high-frequency data from European stock index futures trading. Our sample covers ECB press conferences between January 2009 and December 2017, during which un-conventional monetary policy measures (UMPM) substantially increased communication com-plexity. Analysing the linguistic complexity of the introductory statements and differentiating between press conferences with and without UMPM-announcements, we find more complex communication, i.e. high linguistic complexity and UMPM-announcement, is associated with a lower level of contemporaneous trading activity. Moreover, complex communication leads to a temporal shift in trading activity towards the subsequent Q&A session, which suggests that Q&A sessions facilitate market participants’ information processing. Finally, we document a relatively lower similarity of unconventional monetary policy statements and argue that this might explain our findings.
