Value relevance of IFRS 9: The influence of country factors and heterogeneous strengths in the European banking sector

Abstract

This study focuses on investor reactions to financial instrument recognition and measurement in the banking sector under the new International Financial Reporting Standard (IFRS) 9, Financial Instruments. The research tests the combined value relevance of accounting numbers before and after the mandatory transition to IFRS 9 in Europe. Furthermore, we verify the influence of country factors and heterogeneous strengths on the value relevance of the aforementioned standard. To this end, we adopt a sample consisting of 215 banks listed in Europe, for the years 2015–2020. We find a significant change in the explanatory power of value-relevance regressions in 2015–2017 compared to 2018–2020. In addition, we find that accounting numbers have incremental value relevance in countries characterized by “good” governance indicators and high heterogeneous strength, namely investors pay attention to the strength of the bank authority. This study makes three main contributions to the literature. First, it complements the IFRS 9 literature by providing new evidence. Second, its insights can be used to support investment decisions. Last, the findings help regulators and standard-setters to verify the impact of the new measures delineated by the standard.
