Basel III capital buffers and Canadian credit unions lending: Impact of the credit cycle and the business cycle

We take advantage of the long-standing regulation of the risk-based capital and the leverage ratio in Canada to provide empirical evidence on the relation between the credit unions' capital buffers and loans to members. Based on a unique sample of the 100 Canadian largest credit unions from 1996 to 2014, we find that both the risk-based capital buffer and the leverage buffer are positively related to changes in loans and loan growth. However, changes in these two types of buffers are negatively related to changes in the loans to assets ratios. This finding suggests that to adjust their capital buffers, Canadian credit unions curtail their loans and underscores the importance of the Basel III conservation and the countercyclical buffer requirements in fostering credit. Further, we show that the risk-based capital buffer is positively related to the credit cycle. However, a mechanical application of the rule based on the credit-to-gross domestic product (GDP) gap to activate the countercyclical buffer, would have misguided Canadian credit unions.     

Capital management in mutual financial institutions

Capital management by mutual financial institutions (such as credit unions) provides a valuable testing ground for assessing the impact of capital regulation and theories of managerial behaviour in financial institutions. Limited access to external equity capital means that capital accumulation must be met primarily by reliance on retained earnings. To deal with shocks to the capital position and avoid breaching regulatory requirements, managers will aim to have a buffer of capital in excess of the regulatory minimum. Moreover, mutual governance arrangements and an absence of capital market discipline mean that managers have discretion to set target capital ratios which differ significantly from industry averages. This paper develops a formal model of capital management and risk management in mutual financial institutions such as credit unions which reflects these industry characteristics. The model is tested using data from larger credit unions in Australia, which have been subject to the Basel Accord Risk Weighted Capital Requirements since 1993. The data supports the hypothesis that credit unions manage their capital position by setting a short term target profit rate (return on assets) which is positively related to asset growth and which is aimed at gradually removing discrepancies between the actual and desired capital ratio. Desired capital ratios vary significantly across credit unions. There is little evidence of short run adjustments to the risk of the asset portfolio to achieve a desired capital position.     

Sovereign asset values and implications for the credit market

Using the contingent claim approach and market data on sovereign credit default swaps we assess the drivers of a country's risk perception. Deriving market-based asset values for a set of advanced economies we gain insights into the capital markets' perspectives on sovereign creditworthiness. We find the market-based asset values to be positively influenced by debt and to be an early risk indicator for economic developments. In a cross-section analysis we identify drivers of the economic risk of countries. Clustering the countries according to their debt to asset value ratios provides further insights into the market perceptions of sovereign credit risk. For example we find that the asset values of countries with higher ratios react to changes in the global equity market. Countries with a lower ratio react more to the political stability within the country.     

Labor unions, bargaining power and corporate bond yield spreads: Structural credit model perspectives

This study investigates labor union effects on bond yield spreads from perspectives of structural credit models by employing American bond observations from 2001 to 2007. This research finds that union strength significantly and positively relates to bond yield spreads (this effect is roughly equal to that of issuer rating for one standard deviation change when controlling for well-known variables). The empirical results also show that the positive effects become weaker when management has higher bargaining power. Additionally, union strength volatility significantly and negatively relates to bond yield spreads and capital structure (leverage). The above results are robust when controlling for credit ratings, collinearity concerns, industry effect and tax effect.     

Herding behaviour in the Australian loan market and its impact on bank loan quality

We examine the effect of herding behaviour on the credit quality of bank loans in Australia. We find that bank herding varies with different types of loans. It tends to be more prevalent in owner‐occupied housing loans and credit cards than other types of loans. During the global financial crisis period, herding in owner‐occupied housing loans was most pronounced due to the flight‐to‐quality phenomenon in the housing sector. Furthermore, we find that the big four banks tend to herd more than smaller and regional banks. Bank herding behaviour is countercyclical, as it is negatively related to real GDP growth and the cost of funding but is positively related to market risk. Regulatory capital requirements may also encourage herding as banks are required to hold less risk‐weighted capital for residential loans. Most importantly, bank herding is related to higher impaired assets and therefore lower loan quality. Our findings may have implications for policymakers and bank regulators.     

Local Currency Sovereign Risk

We introduce a new measure of emerging market sovereign credit risk: the local currency credit spread, defined as the spread of local currency bonds over the synthetic local currency risk‐free rate constructed using cross‐currency swaps. We find that local currency credit spreads are positive and sizable. Compared with credit spreads on foreign‐currency‐denominated debt, local currency credit spreads have lower means, lower cross‐country correlations, and lower sensitivity to global risk factors. We discuss several major sources of credit spread differentials, including positively correlated credit and currency risk, selective default, capital controls, and various financial market frictions.     

Measuring Integrated Market and Credit Risk in Bank Portfolios: An Application to a Set of Hypothetical Banks Operating in South Africa

The banking crises of the ‘90s emphasize the need to model the connections between financial environment volatility and the potential losses faced by financial institutions resulting from correlated market and credit risks. Due to the number of variables that must be modeled and the complexity of the relationships an analytical solution is not feasible. We present here a numerical solution based on a simulation model that explicitly links changes in the relevant variables that characterize the financial environment and the distribution of possible future bank capital ratios. This forward looking quantitative risk assessment methodology allows banks and regulators to identify potential risks before they materialize and make appropriate adjustments to bank portfolio credit qualities, sector and region concentrations, and capital ratios on a bank by bank basis. It also has the potential to be extended so as to assess the risks of correlated failures among a group of financial institutions (i.e., systemic risk analyses). This model was applied by the authors to the study of the risk profile of the largest South African Banks in the context of the Financial System Stability Assessment program undertaken by the IMF in 1999. In the current study, we apply the model to various hypothetical banks operating in the South African financial environment and assess the correlated market and credit risks associated with business lending, mortgage lending, asset and liability maturity matches, foreign lending and borrowing, and direct equity, real estate, and gold investments. It is shown to produce simulated financial environments (interest rates, exchange rates, equity indices, real estate price indices, commodity prices, and economic indicators) that match closely the assumed parameters, and generate reasonable credit transition probabilities and security prices. As expected, the credit quality and diversification characteristics of the loan portfolio, asset and liability maturity mismatches, and financial environment volatility, are shown to interact to determine bank risk levels. We find that the credit quality of a bank's loan portfolio is the most important risk factor. We also show the risk reduction benefits of diversifying the loan portfolio across various sectors and regions of the economy and the importance of accounting for volatility shocks that occur periodically in emerging economies. Banks with high credit risk and concentrated portfolios are shown to have a high risk of failure during periods of financial stress. Alternatively, banks with lower credit risk and broadly diversified loan portfolios across business and mortgage lending are unlikely to fail even during very volatile periods. Asset and liability maturity mismatches generally increase bank risk levels. However, because credit losses are positively correlated with interest rate increases, banks with high credit risk may reduce overall risk levels by holding liabilities with longer maturities than their assets. Risk assessment methodologies which measure market and credit risk separately do not capture these various interactions and thus misestimate overall risk levels.     

The impact of FDICIA and prompt corrective action on bank capital and risk: Estimates using a simultaneous equations model

One of the requirements of the Federal Deposit Insurance Corporation Improvement Act (FDICIA) was that bank regulators establish capital ratio zones that mandate prompt corrective action (PCA) and early intervention in troubled banks. However, prior research suggests that increases in regulatory capital standards can lead to offsetting increases in risk. This paper develops and estimates a 3SLS model to examine the simultaneous impact of PCA on both bank capital and credit risk. The results document that the FDICIA was effective in that, subsequent to its passage, US banks increased their capital ratios without offsetting increases in credit risk.     

Capital Structure Choice in a Nascent Market: Evidence from Listed Firms in China

We study the capital structure decisions of listed firms in China between 1992 and 2001. The Chinese market exhibits high information asymmetry, phenomenal growth, highly concentrated ownership, and a lack of external market for corporate control. We find that Chinese firms use little long-term debt, which is positively (negatively) related to firm size and tangibility (profitability and growth options). These results are robust to the degree of seasoning after the initial public offering and private versus State ownership. Although industry membership is important, the development and growth of the stock market did not affect the long-term debt ratios over the years.     

Prudence and financial self-regulation in credit unions in Northern Ireland

Credit unions in Northern Ireland are subject to a unique combination of statutory oversight and self-regulation. This paper investigates the association between prudence and the monitoring of financial ratios by credit union trade associations. We find that compliance with the mandated level of capital reserves is uniformly high, regardless of the existence or extent of self-regulation. However, after controlling for cross-sectional differences in profitability, age, size, growth and common bond type a positive association exists between self-regulation and financial ratios measuring prudence and loan book quality. These findings have policy implications for the regulation of credit unions in Northern Ireland and elsewhere regarding potential regulatory cost savings from reliance on self-regulation provided by trade associations.     

On the Latin American Credit Drivers

We add to the literature about credit in Latin America by assessing what has been driving the recent and heterogeneous expansion of credit to gross domestic product based on supply and demand variables. We chose working with these emerging economies due to the low levels of human capital, the divergent patterns of evolution of economic variables and the vulnerability of credit expansion. According to balanced panel estimations, our main findings in terms of public policy suggest that credit reflects a financial deepening characterized by a higher bank concentration and by a policy able to stimulate saving even practicing lower deposit interest rates.     

On the determinants of bank interest margins under credit and interest rate risks

This paper explores the determinants of optimal bank interest margins based on a simple firm-theoretical model under multiple sources of uncertainty and risk aversion. The model demonstrates how cost, regulation, credit risk and interest rate risk conditions jointly determine the optimal bank interest margin decision. We find that the bank interest margin is positively related to the bank's market power, to the operating costs, to the degree of credit risk, and to the degree of interest rate risk. An increase in the bank's equity capital has a negative effect on the spread when the bank faces little interest rate risk. The effect of rising interbank market rate on the spread is ambiguous and depends on the net position of the bank in the interbank market. Our findings provide alternative explanations for the empirical evidence concerning bank spread behavior.     

Stress testing German banks against a global credit crunch

This paper investigates the impact of a global credit crunch on the corporate credit portfolios of large German banks using a two-stage approach. First, a macroeconometric simulation model (NiGEM) is used to forecast the impact of a substantial increase in the cost of business capital for firms worldwide in three particularly export-oriented industry sectors in Germany. Second, the impact of this economic multi-sector stress on bank credit portfolios is captured by a state-of-the-art Credit Metrics-type portfolio model with sector-dependent unobservable risk factors as drivers of the systematic risk. In our assessment of capital ratios, we confirm that both the increase of the capital charge for the unexpected loss and the increase in banks’ expected losses need to be considered. We also find that the availability of granular information at the level of borrower-specific probabilities of default has a significant impact on the stress test results.     

Does the ownership structure matter for banks’ capital regulation and risk-taking behavior? Empirical evidence from a developing country

This paper applies the two-stage least squares (2SLS) estimator to examine the bi-directional relationship between banks’ capital regulation and risk-taking behavior concerning the impact of ownership structure. We have used a balanced panel dataset of banks from a developing country over the most recent period between 2006 and 2014. The empirical findings of this study suggest that higher capital regulation enhances banks’ stability when it combats with credit risk but higher credit risk often persuades abating capital ratio. Particularly, the key results are as follows: (i) the higher association of minority active shareholding in stability issues is positive; (ii) the higher contribution of active share holding promotes banks’ capital ratio; (iii) the lower ownership concentration prevents credit risk; (iv) private commercial banks are more risk averse and stable than state-owned banks and other type of banks; and (v) notably, Islamic banks show their superiority through overall performance despite their lower capital stability than conventional banks. Besides, no models show significant non-linear relationship between capital regulation and risk-taking except models of stability show a U-shaped relation in capital equation, indicating that when regulatory pressure works in a country then bank lose solvency at the initial stage. Finally, it also provides some imperative policy implications which will be very useful for a wide range of stakeholders.     

Investment and bank credit recovery after banking crises

In this paper, we aim to investigate (a) the dynamic adjustment of investment-to-GDP ratio and bank credit-to-GDP ratio following banking crisis episodes; (b) whether the adjustment of investment and bank credit ratios varies with several country and crisis characteristics. Based on a sample of 79 developed and emerging countries over the 1973–2010 period, our results suggest that in the aftermath of banking crises, investment ratio declines but swiftly recovers to its pre-crisis level within two to three years. Bank credit declines significantly and remains stagnated even in the medium run. In terms of country characteristics, we find that investment and bank credit ratios decline significantly more in advanced countries and countries with higher level of capital openness. In addition, investment ratio declines significantly more in countries with higher level of financial development. Finally, we split the banking crises episodes into two categories: those preceded by a domestic credit boom or a surge in net capital inflows, and those that were not preceded by such booms. We find that dynamic adjustment of investment and bank credit ratios differs substantially across the two groups. Existence of a credit boom or a surge in capital inflow in the run-up to the crisis intensifies the length and depth of the decline in investment and bank credit ratios. In fact, we find no statistically significant decline in investment following banking crises that were not preceded by a credit boom or a surge in capital inflows. These results imply that deleveraging is costly to the economy.     

Economic and regulatory capital allocation for revolving retail exposures

We present two internal capital allocation models and compare the capital ratios they generate with those prescribed by the latest revision of Basel’s New Capital Accord proposal for advanced retail portfolios, which allows for explicit future margin income recognition. Given a test portfolio of credit card exposures that we assemble, we find that Basel’s ratios are closer to those generated by our models for low credit risk segments. We attribute the discrepancies to the different ways Basel and our models account for future margin income, to Basel’s assumptions about asset correlations and to one model taking macroeconomic conditions into account.     

Trade Credit Risk Management: The Role of Executive Risk‐Taking Incentives

In this study we investigate how executive equity incentives affect companies’ risk‐taking behavior in relationships with their customers. We hypothesize and find that executive risk‐taking incentives provided by options are positively related to the degree of trade credit riskiness measured both as the amount of total trade credit a firm extends to all its customers and as the amount of trade credit a firm extends to customers with a high probability of default. We also find that the measures of trade credit riskiness are positively related to the firm's future stock return volatility, suggesting that the customer default risk inherent in customer‐supplier trade credit relationships represents an important economic source of the overall supplier‐firm riskiness. The findings of the study provide insights into why firms facing financial difficulties are not denied trade credit.     

Incorporating the dynamics of leverage into default prediction

A firm’s current leverage ratio is one of the core characteristics of credit quality used in statistical default prediction models. Based on the capital structure literature, which shows that leverage is mean-reverting to a target leverage, we forecast future leverage ratios and include them in the set of default risk drivers. An out-of-sample analysis of default predictions from a hazard model reveals that the discriminative power increases substantially when leverage forecasts are included. We further document that credit ratings contain information beyond the one contained in standard variables but that this information is unrelated to forecasts of leverage ratios.     

Capital adequacy rules, catastrophic firm failure, and systemic risk

This paper studies capital adequacy rules based on Value-at-Risk (VaR), leverage ratios, and stress testing. VaR is the basis of Basel II, and all three approaches are proposed in Basel III. This paper makes three contributions to the literature. First, we prove that these three rules provide an incentive to increase the probability of catastrophic financial institution failure. Collectively, these rules provide an incentive to increase (not decrease) systemic risk. Second, we argue that an unintended consequence of the Basel II VaR capital adequacy rules was the 2007 credit crisis. Third, we argue that to reduce systemic risk, a new capital adequacy rule is needed. One that is based on a risk measure related to the conditional expected loss given insolvency.     

The Silent Majority: Private U.S. Firms and Financial Reporting Choices

This study uses a comprehensive panel of tax returns to examine the financial reporting choices of medium-to-large private U.S. firms, a setting that controls over $9 trillion in capital, vastly outnumbers public U.S. firms across all industries, yet has no financial reporting mandates. We find that nearly two-thirds of these firms do not produce audited GAAP financial statements. Guided by an agency theory framework, we find that size, ownership dispersion, external debt, and trade credit are positively associated with the choice to produce audited GAAP financial statements, while asset tangibility, age, and internal debt are generally negatively related to this choice. Our findings reveal that (1) equity capital and trade credit exhibit significant explanatory power, suggesting that the primary focus in the literature on debt is too narrow; (2) firm youth, growth, and R&D are positively associated with audited GAAP reporting, reflecting important monitoring roles of financial reporting; and (3) many firms violate standard explanations for financial reporting choices and substantial unexplained heterogeneity in financial reporting remains. We conclude by identifying opportunities for future research.
