Impact of Implementation of IFRS 9 on Czech Banking Sector

The aim of this study is to provide an overview of the principles of IFRS 9 implementation and to analyse its impact on the Czech banking sector. Unlike the previous IAS 39 standard, valid until the end of 2017, the new accounting rules require banks to estimate forward-looking expected credit losses (ECL) while considering relevant exposure level information as well as available macroeconomic predictions. Due to the increased complexity of the ECL models and changing macroeconomic expectations, we hypothesize that the new standard leads to increased volatility of loan loss allowances. This hypothesis is empirically tested and more or less confirmed by an analysis of the quarterly flows of allowances for a sample of large Czech banks from the years 2016-2017 under IAS 39 and from 2018-2019 under IFRS 9.
