IFRS 9 implementation and bank risk
研究了IFRS 9实施对银行风险的影响，发现其降低了银行风险，尤其对高风险银行和监管严格国家的银行效果更明显。
In this paper, we investigate the impact of IFRS 9 – Financial instruments on bank risk. Using a sample of 666 banks across 61 countries for the period 2016–2019, we find a decrease in bank risk following the implementation of IFRS 9. This implies that the forward-looking loan loss provisioning, mandated under IFRS 9, facilitates a reduction in bank risk. We find this effect to be more pronounced for riskier banks, suggesting that the implementation of IFRS 9 is a sign of effective regulation for banks rather than a manifestation of regulatory overreach. We also find the effect to be greater for banks in countries with stronger accounting regulatory enforcement and high banking supervision intensity. Overall, our results, which are robust to different estimation techniques, including multi-level hierarchical regressions and entropy balancing estimations, show that increased transparency and timely recognition under IFRS 9 reduce bank risk.
