The purpose of this paper is to assess the effectiveness of the transitional provisions for the impact of International Financial Reporting Standard 9 (IFRS 9) as a supervisory tool to strengthen a bank’s capital base. The new IFRS 9 provisions are a significant banking supervisory measure of the so-called Capital Requirements Regulation (CRR) Quick Fix to mitigate possible adverse effects of the COVID-19 pandemic on banks. With the discharge rules, the supervisor aims to strengthen the banks’ regulatory capital in order to ensure the supply of credit to households and companies at all times. Based on the published disclosure reports of 107 significant European banks at the reporting dates end 2019 and June 2020, our study analysed how many banks already apply the transition rules, whether there are geographical focusses and to what extent banks use the new CRR Quick Fix adjustments. To the best of our knowledge, this paper is the first empirical analysis of the extent to which European banks use the original IFRS 9 transitional arrangements and COVID-19 extension and what effects its use has on their common equity Tier 1 (CET1) capital. The results are of interest to regulators, bank managers and analysts alike, as they fundamentally demonstrate the effectiveness of this particular regulatory tool.

本文旨在评估过渡条款对国际财务报告准则9（IFRS 9）的影响的有效性，以此作为加强银行资本基础的监督工具。IFRS 9的新规定是对所谓的资本要求法规（CRR）快速修复的一项重要的银行监管措施，目的是减轻COVID-19大流行对银行的可能的不利影响。根据清算规则，监管者旨在加强银行的监管资本，以确保始终向家庭和公司提供信贷。根据截至2019年和2020年6月的107个重要欧洲欧洲银行的公开披露报告，我们的研究分析了多少家银行已应用过渡规则，是否有地理重点，以及银行在多大程度上使用了新的CRR Quick Fix调整。就我们所知，本文是对欧洲银行在多大程度上使用原始的IFRS 9过渡安排和COVID-19扩展及其对普通股一级资本（CET1）的影响的第一份实证分析。监管机构，银行经理和分析师都对结果感兴趣，因为它们从根本上证明了这一特定监管工具的有效性。
