When setting banks regulatory capital requirement based on their contribution to the overall risk of the banking system we need to consider that the risk of the banking system as well as each banks risk contribution changes once bank equity capital gets redistributed. Therefore the present paper provides a theoretical framework to manage the systemic risk of the banking system in Nigeria based on macroprudential capital requirements, which requires banks to hold capital that is proportional to their contribution to systemic risk. Using a sample of 10 Nigerian banks, we reallocate capital in the system based on two scenarios; firstly in the situation where the system shocks do not exist in the system, we find that almost all banks appear to hold more capital; secondly, we also consider the situation where the system shocks exist in the system; we find that almost all banks tend to hold little capital on four risk allocation mechanisms. We further find that despite the heterogeneity in macroprudential capital requirements, all risk allocation mechanisms bring a substantial decrease in the systemic risk. The risk allocation mechanism based on ΔCoVaR decreases the average default probability the most. Our results suggest that financial stability can be substantially improved by implementing macroprudential regulations for the banking system.

Did banks curb lending to creditworthy small and mid-sized enterprises (SME) during the COVID-19 pandemic? Sitting on top of minimum capital requirements, regulatory capital buffers introduced after the 2008 global financial crisis (GFC) are costly regions of "rainy day" equity capital designed to absorb losses and provide lending capacity in a downturn. Using a novel set of confidential loan level data that includes private SME firms, we show that "buffer-constrained" banks (those entering the pandemic with capital ratios close to this regulatory buffer region) reduced loan commitments to SME firms by an average of 1.4 percent more (quarterly) and were 4 percent more likely to end pre-existing lending relationships during the pandemic as compared to "buffer-unconstrained" banks (those entering the pandemic with capital ratios far from the regulatory capital buffer region). We further find heterogenous effects across firms, as buffer-constrained banks disproportionately curtailed credit to three types of borrowers: (1) private, bank-dependent SME firms, (2) firms whose lending relationships were relatively young, and (3) firms whose pre-pandemic credit lines contractually matured at the start of the pandemic (and thus were up for renegotiation). While the post-2008 period saw the rise of banking system capital to historically high levels, these capital buffers went effectively unused during the pandemic. To the best of our knowledge, our study is the first to: (1) empirically test the usability of these Basel III regulatory buffers in a downturn, and (2) contribute a bank capital-based transmission channel to the literature studying how the pandemic transmitted shocks to SME firms.

Regulators responded with an array of strategies to shore up weaknesses exposed by the 2008 financial crisis. This chapter focuses on reforms to bank capital regulation. We first discuss the ways in which the post-crisis Basel III reforms recalibrated the existing framework by improving the quality of capital, increasing the quantity of capital, and improving the calculation of risk weights. We then shift to the major structural changes in the regulatory capital framework—capital buffers on top of the minimum requirements; a leverage ratio that explicitly accounts for off-balance-sheet exposures; risk-based and leverage capital surcharges on the largest banks; bail-in debt to facilitate orderly resolution; and forward-looking stress tests. We conclude with a quantitative assessment of the evolution of capital in the global banking system and in the US banking sector.

Scientific-methodical approaches to stress testing Ukrainian banking system in the context of the banks groups: state-owned, owned by Russia, foreign, private Ukrainian are analyzed in this study. It identifies an influence of the different groups in regulate the level of financial stability of the banking system. Highest level of financial stability of Ukrainian banking system was found to be connected with activity foreign banks from Eastern Europe and Central Asia exclaims banks owned by Russia and Ukraine. The proposed study, by using NBU stress testing scenario and by impacting of the devaluation of the national currency, presents the improved methodology for determining the level of financial stability of banking groups in terms of crisis increase exchange rate. This study was conducted by way of review of the data on bank core capital and regulatory capital, real and nominal GDP, consumer price index and reducing the rate of UAH to EUR.

Maintaining proper financial stability of each banking institution is one of the main tasks facing the banking system of Ukraine. This enables operational control over the financial strength of banking activities.The purpose of the article is to develop recommendations on the operational control of financial stability of banking and to test them using banking institutions in Ukraine as an example.To execute operational control over the financial stability of banking, economic standards of banking regulation are grouped under the “at least” or “not exceeding” principle. To determine their change over time, Shewhart control charts are proposed.The recommendations were tested through the example of the Ukrainian banking institutions (with state, foreign and private capital). It was found out that in 2017–2019, the following three economic standards of banking regulations were not met: regulatory capital adequacy, high credit risk, and average investments; besides, there were two standards at the limit of control value: the ratio of regulatory capital to total assets and the maximum amount of credit risk per counterparty.To improve the financial status of banking institutions, it is recommended to take organizational and financial measures to change the average value of the relevant economic standards for banking regulation to a level that ensures financial stability.

The objective of this article is to analyze the effects of procyclical variations of the capital requirements for risk coverage on financial stability in the CEMAC[1]. In order to achieve this objective, we have specified and estimated a panel VAR model using the structural factorization method on quarterly Central Bank data over the period 2006-2017. Firstly, the results show that procyclical capital adjustments in the CEMAC region lead to short-term financial instability through the contraction of credit to the private sector. Secondly, despite the low level of financial development, the effects maintained by the adjustment of monetary policy instruments in the short term remain significant on price stability. Finally, in the long term, the procyclicality of regulatory capital makes it possible to revive economic activity and guarantee financial stability. These results lead us to recommend the adoption of a more discretionary monetary policy so as to make more procyclical the capital requirement.     [1] Economic Community of Central African States comprising Cameroon, Central African Republic, Chad, Congo, Gabon and Equatorial Guinea.

Ensuring and strengthening the financial sustainability of banks is a difficult and not completely resolved task. It is inherent not only to developed countries, it has also be¬come nationally important in Ukraine, which was largely predetermined by the specifics of the domestic banks development. This is explained, in particular, by the banking insti¬tutions’ focus mainly on the relatively short-term activity, the need to work under high risk, resulting from economic and political instability in the country. Therefore, nowa¬days, it is urgent for each Ukrainian bank to focus on the main strategic objective – effec¬tive management and ensuring financial sustainability. The purpose of this study is to assess the current state and identify the features of ensuring financial sustainability of the banking system of Ukraine.It was pointed out in the study that the negative tendency to increase the number of in¬solvent commercial banks during 2012–2017 indicates problems with providing finan¬cial sustainability to commercial banks. The tendencies have been revealed that testify to the problems of the banking system capitalization in Ukraine, which greatly affects its financial stability. Given the analysis of indicators of banks financial sustainability that characterize the bank capital adequacy, the conclusion is made on ambiguous as¬sessment of sufficient level of capitalization, since despite the correspondence of most values of coefficients to the indicators, there is a lack of capitalization of the domestic banking system and equity capital concentration. In general, the results made it pos¬sible to identify trends in the development of capital ratios and financial sustainability indicators and to shape appropriate measures to increase the level of capitalization in order to ensure the financial sustainability of the banking system.

Banks’ financial reporting requirements and discretionary choices may affect financial stability by altering one or more of the likelihood that banks violate regulatory capital requirements, banks’ internal discipline over risk management and financial reporting, and external market and regulatory discipline over banks. In this article, I discuss five recent empirical papers that examine these channels linking banks’ financial reporting to financial stability. I explain how these papers identify economic contexts and associated financial reporting constructs that enable powerful examinations of these channels, and how they employ research designs that meaningfully address the issues regarding valid causal inference raised by Acharya & Ryan (2016) . I conclude that, while each study examines a specific channel or two in a specific setting, collectively the literature is making steady progress in enhancing our understanding of the causal forces at play in the channels linking banks’ financial reporting and financial stability, the goal set forth by Acharya & Ryan (2016) . I also identify open questions that these papers suggest for future research on the effects of banks’ financial reporting on financial stability.

Interest Rate Models

According to the Basel regulation banks may use internal risk models to measure interest rate risk and calculate regulatory capital requirements. Under its pillar II the Basel framework grants leeway to banks in their choice of these models. We therefore focus on how well interest rate models describe real interest rate movements empirically and which impact the model choice has on the economic value of bank equity during the financial crisis. Furthermore, we address the question how different choices of interest rate models affect the overall financial stability. To this end we estimate eight different interest rate models for three different currencies (USD, EUR, CHF) using the Generalized Method of Moments (GMM). Then we approximate the balance sheet of a typical Swiss bank during the financial crisis and run Monte Carlo simulations of the balance sheet using the estimated interest rate models. Our results show that the required economic value of equity for a bank varies considerably with the different choices of interest rate models. However, the interest rate models which are empirically best fitting do not imply aggregate financial stability. Thus, banks’ choices of interest rate models to calculate regulatory capital requirements may have a crucial impact on overall financial stability.

Minimum Capital

The Basel II regulatory framework significantly increased the resilience of the banking system, but proved ineffective in preventing the 2008/9 financial crisis. The subsequent introduction of Basel III aimed, inter alia, to supplement bank capital using buffers. The countercyclical buffer boosts existing minimum capital requirements when systemic risk surges are detected. Bolstering capital in favourable economic conditions cushions losses in unfavourable conditions, thereby addressing capital requirement procyclicality. This paper contains an overview of the countercyclical capital buffer and a critical discussion of its implementation as proposed in Basel III. Consequences of the buffer's introduction for South African banks are explored, and in particular, potential systemic risk indicator variables are identified that may be used by the South African Reserve Bank (SARB) as early warning indicators of imminent systemic financial distress. These indicators may be of value to the SARB, which could use them in taking decisions on the build-up and release of the countercyclical buffer for South African banks.

The Global Financial Crisis

AbstractThe role of liquidity in the banking industry is increasingly under the spotlight since the Global Financial Crisis (GFC) in 2007. Prior evidence offers contrasting findings on the role played by liquidity in banks: whilst it ensures systemic financial stability, at the same time it raises agency costs. Notwithstanding this, European banks benefited from a generous liquidity injection following the launch of the Quantitative Easing (QE) programme by the European Central Bank (ECB) in 2015–2016. We leverage on the release of the QE and investigate whether investors’ reactions to the announcements of new liquidity injections vary according to bank-level characteristics of the European banks: namely, their financial soundness, asset portfolio quality and the level of transparency. Our findings document an overall negative market reaction to the QE announcements; at a more fine-grained level of analysis we highlight that banks falling short of the regulatory requirements are not expected to benefit from additional liquidity. This study contributes to the literature on the role of liquidity in banks by showing important boundary conditions to the beneficial role of liquidity in banks, that is—because of the regulatory capital requirements—liquidity is only valuable to investors if it can be reinvested once constraints are overcome.
