Bank activity and funding strategies: The impact on risk and returns

This paper examines the implications of bank activity and short-term funding strategies for bank risk and return using an international sample of 1,334 banks in 101 countries leading up to the 2008 financial crisis. Expansion into noninterest income-generating activities such as trading increases the rate of return on assets, and it could offer some risk diversification benefits at very low levels. Nondeposit, wholesale funding in contrast lowers the rate of return on assets, while it can offer some risk reduction at commonly observed low levels of nondeposit funding. A sizable proportion of banks, however, attract most of their short-term funding in the form of nondeposits at a cost of enhanced bank fragility. Overall, banking strategies that rely prominently on generating noninterest income or attracting nondeposit funding are very risky, consistent with the demise of the US investment banking sector.     

Financial structure change and banking income: A Canada–U.S. comparison

Data suggest that the Canadian financial structure, and particularly indirect finance (e.g., banking), have become more market-oriented. We associate this financial trend in part with the regulatory changes that have occurred in Canada since the 1980s. Financial intermediaries are increasingly involved with financial market activities—e.g. off-balance sheet (OBS) activities such as underwriting securities. In this article we analyze the noninterest income attributable to these financial market activities. We find that the variance of Canadian banks’ aggregate operating-income growth is rising because of the increased contribution of noninterest income. Overall, our analysis corroborates the U.S. findings of Stiroh and Rumble (Stiroh, K., 2006. A portfolio view of banking with interest and noninterest assets. Jounal of Money, Credit, and Banking 38, 1351–1361; Stiroh, K., Rumble, A., 2006. The darkside of diversification: the case of U.S. financial holding companies. Journal of Banking and Finance 30, 2131–2161): by contributing to banking income volatility, market-oriented activities do not necessarily yield straightforward diversification benefits to Canadian banks.     

The Roles of Corporate Governance in Bank Failures during the Recent Financial Crisis

We analyze the roles of bank ownership, management, and compensation structures in bank failures during the recent financial crisis. Our results suggest that failures are strongly influenced by ownership structure: high shareholdings of lower‐level management and non‐chief executive officer (non‐CEO) higher‐level management increase failure risk significantly. In contrast, shareholdings of banks’ CEOs do not have a direct impact on bank failure. These findings suggest that high stakes in the bank induce non‐CEO managers to take high risks due to moral hazard incentives, which may result in bank failure. We identify tail risk in noninterest income as a primary risk‐taking channel of lower‐level managers.     

New Evidence on the Determinants of Bank Risk

This paper uses equity returns for publicly traded US bank holding companies (BHCs) from 1997 to 2004 to identify the determinants of risk, measured by equity market volatility, and examine how they have evolved. The results indicate that balance sheet items such as commercial and industrial loans and consumer lending and income statement items such as other noninterest income drive the cross-sectional differences in BHC risk. Newly mandated regulatory data on the components of other noninterest income show that investment banking, servicing, securitization income, gains from loan sales, gains other asset sales, and other noninterest income are particularly volatile activities. This highlights the value of increased transparency as a means to improve market discipline and reduce the opacity of complex financial institutions. Finally, in the years after 2000, the locus of risk has shifted off of the balance sheet and onto the income statement as investors identify the new risks associated with evolving and expanding bank activities.     

Are there diversification benefits of increasing noninterest income in the Chinese banking industry?

This paper assesses the potential diversification benefits of the increasing reliance on nontraditional business activities based on data from the Chinese banking industry in 1986–2008. At the aggregate level, there are diversification benefits of the increase in noninterest income. However, noninterest income has higher volatility and cyclicality than net interest income, and the marginal benefit of diversification decreases with the increase in noninterest income. At the bank level, the correlation coefficients of the growth rates of net interest income and noninterest income are mostly negative, which also suggests that there are diversification benefits of increasing the noninterest income. However, further model analysis indicates that the effect of the noninterest income share on the Chinese banking industry's revenue and risk is not significant. Overall, our findings suggest that noninterest income diversifies bank revenue, but increased reliance on noninterest income may worsen the risk/return trade-off for the Chinese banking industry.     

An analysis of nontraditional activities at U.S. commercial banks

In recent years, commercial banking in the United States has experienced a decline in its traditional business of financing loans by issuing deposits. Simultaneously, banks have become more involved in nontraditional activities that provide financial services and generate fee income. As a result, real aggregate noninterest income has risen relative to income from traditional activities. This paper examines features common to banks that are heavily engaged in nontraditional areas. The empirical analysis suggests that these banks tend to be larger, have smaller net interest margins, have relatively fewer core deposits, and exhibit less risk. These findings have intuitive appeal and conform to conventional wisdom; while larger banks have fewer core deposits and face more competitive interest rate conditions, resulting in narrow spreads from traditional intermediation, they have more diverse sources of revenue and greater access to financial markets, which reduces risk.     

Symposium on Financial Institutions

Financial institutions are the topic of the 2003 Eastern Finance Association Symposium. The symposium papers illustrate the importance of bank research for improving our understanding of both financial and nonfinancial firms. Benston begins the symposium with an overview of banking. Three papers consider different aspects of banks' commercial lending: Frame, Padhi, and Woosley; Gottesman and Roberts; and Gonas, Highfield, and Mullineaux. Next, DeYoung and Rice analyze increases in bank's increased noninterest income. Finally, two papers illustrate the benefits of using banking data: Hasan and Wall, in examining the management of financial reporting, and Sfiridis and Daniels, in examining the implications of different organizational forms.     

Noninterest income mix and bank performance: Generalized propensity score fractional dose–response function evidence

This paper investigates the impact of different levels of noninterest income on the risk-adjusted profitability and financial stability of banks in the Middle Eastern and North African banking industry from 1988 to 2020. We apply a program impact evaluation analysis, using the generalized propensity score-fractional dose–response function method, and assess the effect of each level (or dose) of noninterest income mix on bank performance (the dose–response function). Splitting the sample into Gulf Cooperation Council- and non-Gulf Cooperation Council-based banks reveals that while higher levels of revenue diversification are beneficial for the former, a focus on traditional banking activities is preferable for the latter to achieve the best performance. The findings could serve as an early warning flag for bank managers, policy-makers, and regulators in dealing with these strategic shifts.     

The relationship between net interest margin and noninterest income using a system estimation approach

This paper examines the determinants of bank net interest margin (NIM) and non-traditional banking activities (NII). A system estimation approach is employed to control for the simultaneity between NIM and NII for commercial banks in a group of 28 financially liberalized countries during the period between 1997 and 2004. We find a statistically significant negative relationship between NIM and NII for the period between 1997 and 2002. A generally positive but statistically insignificant association between NIM and NII is found for the subsequent period (2003–2004). Banks’ increasing involvement in non-traditional activities is negatively correlated with risk-adjusted profitability measures in the former subperiod, suggesting no obvious diversification benefits. However, the share of noninterest income is positively related to the return on assets (ROA) and the return on equity (ROE) for the latter subsample.     

The impact of off-balance-sheet activities on banks returns: An application of the ARCH-M to Canadian data

This paper revisits the impact of off-balance-sheet (OBS) activities on banks risk-return trade-off. Recent studies (e.g., Stiroh and Rumble, 2006) show that increasing OBS activities does not necessarily yield straightforward diversification benefits for banks. However, introducing a risk premium in the standard banks returns models, and resorting to an ARCH-M procedure, Canadian data suggest that banks risk-return trade-off displays a structural break around 1997. In the second subperiod of our sample (1997–2007), we find that the noninterest income generated by OBS activities no longer impacts banks returns negatively. While during the first period (1988–1996) the volatility variable is not significant in any returns equations, a risk premium eventually emerges, pricing the risk associated to OBS activities.     

Bank Diversification and Overall Financial Strength: International Evidence

There are many studies in the finance and management literature that examine the impact of diversification on performance. Yet, the literature remains inconclusive as for the potential benefits in terms of risk and return. The present study aims to re‐examine this issue, while proposing a methodological framework that integrates various bank performance and risk indicators into a single measure of financial strength. Using an international sample of commercial banks, we find that diversification in terms of income, earning assets, and on‐ and off‐balance sheet activities influences positively their financial strength. We also find that income diversification can be more beneficial for banks operating in less developed countries compared to banks in advanced and major advanced economies. However, we observe the opposite in the case of diversification between off‐balance sheet and on‐balance sheet activities. Furthermore, the results reveal that income and earning assets diversification can mitigate the adverse effect of the financial crisis on bank financial strength. We continue to find a positive relationship between diversification and financial strength when we account for nesting effects, endogeneity, as well as when using an alternative approach for the construction of the financial strength indicator.     

Cross-country determinants of bank income smoothing by managing loan-loss provisions

This paper studies the determinants of income smoothing by management of loan-loss provisions in banks around the world. Using a panel database of 3221 bank-year observations from 40 countries and controlling for unobservable bank effects and for the endogeneity of explanatory variables, we find that bank income smoothing depends on investor protection, disclosure, regulation and supervision, financial structure, and financial development. Results suggest there is less bank income smoothing not only with the strength of investor protection, but also with the extent of accounting disclosure, restrictions on bank activities, and official and private supervision, while there is more income smoothing with market orientation and development of a country’s financial system.     

Heterogeneous Background Risks and Portfolio Choice: Evidence from Micro‐level Data

We construct a set of household‐level background risk variables to capture the covariance structure of three nonfinancial assets and two financial assets. These risks are in general statistically significant and economically important for a household's stock market participation and stockholdings. A one‐standard‐deviation increase in background risks reduces the participation probability by 11% and the stockholdings‐to‐wealth ratio by 4%. The volatilities of labor income, housing value, and business income reduce a household's participation and stockholdings. A household with labor income highly correlated with stock (bond) returns is less (more) likely to invest in stock.     

Bank Competition: Measurement,Decision‐Making,and Risk‐Taking

This paper investigates whether greater competition increases or decreases individual bank and banking system risk. Using a new text‐based measure of competition, and an instrumental variables analysis that exploits exogenous variation in bank deregulation, we provide robust evidence that greater competition increases both individual bank risk and a bank's contribution to system‐wide risk. Specifically, we find that higher competition is associated with lower underwriting standards, less timely loan loss recognition, and a shift toward noninterest revenue. Further, we find that higher competition is associated with higher stand‐alone risk of individual banks, greater sensitivity of a bank's downside equity risk to system‐wide distress, and a greater contribution by individual banks to downside risk of the banking sector.     

Small European banks: Benefits from diversification?

Motivated by the liberalisation and harmonisation of financial systems in Europe, we investigate whether the observed shift into non-interest income activities improves performance of small European credit institutions. Using a sample of 755 small banks for the period 1997–2003, we find no direct diversification benefits within and across business lines and an inverse association between non-interest income and bank performance. Our findings are robust to a set of sensitivity analyses using alternative samples and controlling for the regulatory environment. Furthermore, the results provide circumstantial evidence for the presence of economies of scale. The absence of benefits of diversification confirms findings for other banking markets and suggests small European banks enter lines of business where they currently lack expertise and experience. These results have implications for bank supervisors, regulators and bank managers.     

Money Creation: Tax or Public Liquidity?

I revisit the example of non‐neutral anticipated monetary expansions used in Lucas (1995) Nobel Prize Lecture, within a broader definition of monetary policy tools, such as paying a nominal return on money or using open market operations, to show that money expansions increase output by reallocating consumption across heterogenous individuals and time periods. This result survives with noninterest‐bearing cash when the latter does not generate relevant distortions.     

Banks as Tax Planning Intermediaries

We provide the first large‐scale empirical evidence of banks functioning as tax planning intermediaries. We posit that some banks specialize in assisting corporate clients with tax planning. In this role, banks make use of their centrality in financial relationships; access to private information; and ability to structure, execute, and participate in tax planning transactions for clients. We measure bank‐client relationships using loan contracts and measure client tax planning using either the cash effective tax rate or the unrecognized tax benefit balance. Using a difference‐in‐differences design, we find that firms experience meaningful tax reductions when they begin a relationship with a bank whose existing clients engage in above‐median tax planning. The effects of pairing with such tax intermediary banks are concentrated in relationships with larger or longer maturity loans, clients with foreign income or greater credit risk, and when the bank is an industry specialist or has above‐median investment banking activities. Finally, we find that potential clients are more likely to choose tax intermediary banks than nontax intermediary banks, suggesting that tax intermediary banks benefit by attracting new business. Collectively, our results suggest that some banks act as tax planning intermediaries, a role beyond the traditional one of financial intermediary.     

Performance Measures in Earnings‐Based Financial Covenants in Debt Contracts

This paper examines how performance measures are defined in major earnings‐based financial covenants in loan contracts to shed light on the economic rationales underlying the contractual use of performance measures. I find an earnings‐based covenant is typically based on a performance measure close to earnings before interest, tax, amortization, and depreciation expenses (EBITDA). However, my empirical analyses show that EBITDA is less useful in explaining credit risk than earnings before interest and tax expenses (EBIT) and even the bottom‐line net income. Thus, measuring credit risk cannot fully explain the choice of accounting performance measures in earnings‐based covenants. I conjecture that contracting parties choose an EBITDA‐related measure, instead of a measure calculated after depreciation and amortization expenses (e.g., EBIT), to make the performance measure less sensitive to investment activities, which can be controlled through other contractual terms, such as a restriction on capital expenditure, and provide empirical evidence consistent with this conjecture.     

ACTIVITY STRATEGIES,AGENCY PROBLEMS,AND BANK RISK

We investigate whether diversification affects bank risk taking in the U.S. banking industry, and whether this relation is partially explained by agency theory. Our results show that U.S. banks with a relatively high share of noninterest income become riskier when moving toward non-interest-income-generating activities, especially activities from investment banking, proprietary trading, and so on. Diversification not only affects conditional average risk, but also the dispersion of risk. Moreover, diversified banks that received assistance from the Troubled Asset Relief Program (TARP) become riskier than diversified nonrecipients after TARP capital injections. Our main findings are robust to a battery of robustness tests. The results are partially explained under agency frameworks related to poor corporate governance.     

Insurance demand and country risks: A nonlinear panel data analysis

This paper investigates the impact of country risks, including political, financial, and economic risks, on the income elasticity of insurance demand. Using the panel smooth transition regression model, we find that there is a significant regime-switching effect concerning the impact of country risks on the income elasticity of insurance demand. A full-sample analysis shows that the income elasticity of insurance demand decreases when country risks diminish. In a subsample analysis based on income level, legal origin, and restriction on banks' participation in insurance activities, we find that the elasticity diminishes in general when economic risk drops. When political risk is lower, the elasticity decreases in countries with high-income, common law origin, and insurance activities permitted by banks, whereas a clear pattern cannot be identified in the case of financial risk.
