The aim of this paper is to assess how relevant is the topic of sovereign bond valuations in official ECB Executive Board member speeches and, in particular, under what circumstances do ECB officials begin communicating the driving factors of sovereign bond pricing. For this purpose, we downloaded over 2000 public ECB Executive Board member speeches and applied various text mining techniques. The visual analysis revealed that the importance of the topic of sovereign bond pricing and related risk factors in ECB officials’ speeches has greatly fluctuated over time. The main structural break points were linked to the financial market turbulences, but this topic, possibly due to the introduction of sovereign bond purchases, remained relatively popular even after stress episodes. The linkages between the publicly communicated terms of sovereign bond pricing and related risk factors were rather complex and change in respect to the market situation. Meanwhile, the sentiment balance of the credit risk factor was usually on the negative side, while the ones of other terms were much more neutral.
