This paper examines the use of #machinelearning methods in the context of #banks' #capitalrequirements, specifically the internal Ratings Based (#irb) approach. The authors discuss the advantages and risks of using machine learning in this domain, and provide recommendations related to #risk parameter estimations, #regulatory capital, the trade-off between performance and interpretability, international #banking competition, and #governance, #operationalrisk, and training.
" The biggest Shortcoming of the recent reforms to the stabilization of the #financialsystem, such as #baseliii and the American #doddfrankact Act, is that they increase the #capitalrequirements rather than the causes of the increased #risk. It would generally be better to forbid risky and complex #financialproducts than to further increase #regulation complexity."
This working paper analyzes whether the #boe has a legal obligation to adjust #capitalrequirements for #financialinstitutions in response to the #climatecrisis. The paper argues that the BoE, as a public authority, must abide by the #humanrights obligations set out in the European Convention on Human Rights, which are deeply intertwined with climate concerns.
It highlights the increasing #regulatory focus on #climaterisk faced by #canada's #banks, both domestically through the #osfi and globally through the adoption of guidelines proposed by the #tcfd. As regulators seek to impose more #monitoring, #disclosure, and mitigation obligations on #financialinstitutions, the article raises whether banks' #capitalrequirements should be increased to reflect the #risks associated with #climatechange.
"... model uncertainty is a vital component of the current challenges in risk measurement, and therefore the regulator should design risk measures encouraging well-understood prudent decisions over (less understood) risky ones. From this perspective robust regulation should be a desirable goal. To achieve such an objective, simple – but not simpler – rules are needed."
"The increased banking risk mainly attributed to reduction in bank capital and escalated fluctuations in bank profitability."
"… almost 50 percent of insurers at risk of facing additional regulatory scrutiny due to failing four Insurance Regulatory Information System (IRIS) ratios received sufficient internal capital to avoid enhanced regulation. Moreover, the likelihood and extent of internal capital allocation are related to regulatory scrutiny risk and the amount of capital allocated is typically just enough to avoid regulatory scrutiny."
"Under the Single Supervisory Mechanism (SSM) introduced in 2014, the European Central Bank directly supervises significant euro area banks, which hold about 82% of total banking assets. We find that this important supervisory change has positive effects on the return on assets and the return on risk-weighted assets of SSM banks without increasing the risk weights used to calculate regulatory capital."
"We summarize core features of a capital regime such as expected and unexpected losses, regulatory ratios and risk-weighted assets, and minimum requirements and buffers, and then consider where climate-related risk drivers may be relevant."
"Even pioneering forward-looking stress tests cannot feasibly capture all possible tail risks. We propose supplementing the existing capital requirements regime by giving it a stronger precautionary and macroprudential focus, paying particular attention to the prevention of environmental tipping points to avoid systemic and catastrophic impacts on the financial system and macroeconomy."
