The Determinants of Net Interest Margins of Commercial Banks in Mainland China

This paper studies empirically the determinants of Chinese commercial banks' net interest margins from 1996 to 2003. It applies an extension to the Ho and Saunders (1981) model to identify the elements affecting net interest margins. The results indicate that the determinants of net interest margins in the Chinese market include market competition structure, average operating costs, degree of risk aversion, transaction size, implicit interest payments, opportunity cost of reserve, and management efficiency.     

The determinants of bank interest rate margins: an international study

This paper studies the determinants of bank net interest margins (NIMs) in six selected European countries and the US during the period 1988–1995 for a sample of 614 banks. We apply the Ho and Saunders model (Ho, T., Saunders, A., 1981. The determinants of bank interest margins: theory and empirical evidence. Journal of Financial and Quantitative Analyses 16, 581–600) to a multicountry setting and decompose bank margins into a regulatory component, a market structure component and a risk premium component. The regulatory components in the form of interest-rate restrictions on deposits, reserve requirements and capital-to-asset ratios have a significant impact on banks NIMs. The empirical results suggest an important policy trade-off between assuring bank solvency—high capital-to-asset ratios—and lowering the cost of financial services to consumers—low NIMs. The more segmented or restricted the banking system—both geographically and by activity—the larger appears to be the monopoly power of existing banks, and the higher their spreads. Macro interest-rate volatility was found to have a significant impact on bank NIMs; this suggests that macro policies consistent with reduced interest-rate volatility could have a positive effect in reducing bank margins.     

Determinants of bank interest margins: Impact of maturity transformation

This paper explores the extent to which interest risk exposure is priced into bank margins. Our contribution to the literature is twofold: First, we extend the Ho and Saunders (1981) model to capture interest rate risk and expected returns from maturity transformation. Banks price interest risk according to their individual exposure separately in loan and deposit intermediation fees, but reduce (increase) these charges for loans (deposits) when positive excess holding period returns from long-term exposures are expected. Second, we test the model-derived hypotheses not only for the commonly investigated net interest margin but also for interest income and expense margins separately in a sample encompassing the German universal banking sector between 2000 and 2009. Our results suggest that banks price their individual interest rate risk and corresponding expected excess holding period returns via the asset side into the net interest margin. For liabilities, we find that interest rate risk exposure is only priced in by smaller, local banks.     

Factors explaining the interest margin in the banking sectors of the European Union

This study analyses the interest margin in the principal European banking sectors (Germany, France, the United Kingdom, Italy and Spain) in the period 1993–2000 using a panel of 15,888 observations, identifying the fundamental elements affecting this margin. Our starting point is the methodology developed in the original study by Ho and Saunders [Journal of Financial and Quantitative Analysis XVI (1981) 581–600] and later extensions, but widened to take banks' operating costs explicitly into account. Also, unlike the usual practice in the literature, a direct measure of the degree of competition (Lerner index) in the different markets is used. The results show that the fall of margins in the European banking system is compatible with a relaxation of the competitive conditions (increase in market power and concentration), as this effect has been counteracted by a reduction of interest rate risk, credit risk, and operating costs.     

Factors Determining Net Interest Margins in Australia: Domestic and Foreign Banks

This study tests the application of the Ho and Saunders (1981) model of bank net interest margins (NIMs), and its subsequent developments, using Australian data. The core elements of this model apply in Australia. Bank market power is found to increase NIMs, consistent with McShane and Sharpe (1985) , with evidence of bank buying market share and mispricing for risk. Operating costs also have an important role in determining NIMs, together with implied payments and management quality. Bank NIMs are found to have fallen over the study period.

Interest margins and bank regulation in Central America and the Caribbean

This paper examines empirically the determinants of bank interest margins in Central America and the Caribbean over the period 1998–2014. A particular focus is set on the impact of differences in the regulatory environment and market structure across countries in explaining the interest margins of individual banks. Our results suggest that bank market power, operating costs, credit risk, and liquid asset holdings increase the margin between loan and deposit rates, while increased income diversification and GDP growth are associated with lower loan-deposit spreads. When considering information on banking regulation, we find strong evidence to support our main hypothesis that improvements in market quality and liberalization have a significant effect on interest margins. More specifically, reductions in entry requirements to banking, higher involvement of foreign banks, and increased financial statement transparency are associated with significant reductions in interest margins.     

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.     

Usefulness of comprehensive income reporting in Canada

In January 2005 the Canadian Accounting Standards Board (AcSB) issued three new accounting standards that require Canadian firms to mark-to-market certain financial assets and liabilities and recognize the holding gains and losses related to these items as other comprehensive income or as part of net income. The Board’s objectives for issuing the new standards are (i) to harmonize Canadian GAAP with US and International GAAP, (ii) to enhance the transparency and usefulness of financial statements, and (iii) to keep pace with changes in accounting standards in other countries that are moving towards fair value accounting. This paper investigates empirically whether requiring Canadian companies to report comprehensive income and its components provides the securities market with incremental value-relevant information over the traditional historical-cost earnings approach.Previous empirical studies provide mixed evidence on the value relevance of other comprehensive income and its components. This mixed evidence may be attributed partially to the use of as if methodology to construct an ex-ante measure of other comprehensive income prior to the implementation of SFAS 130, which introduces measurement error. In contrast, this study uses actual data on other comprehensive income for a sample of Canadian firms cross-listed in the US in the period 1998–2003. We find evidence that available-for-sale and cash flow hedges components are significantly associated with price and market returns. We also find that aggregate comprehensive income is more strongly associated (in terms of explanatory power) with both stock price and returns compared to net income. However, we find that net income is a better predictor of future net income relative to comprehensive income. Our findings suggest that mandating all Canadian firms to adopt the new accounting standards is expected to enhance the usefulness of financial statements. Our findings, therefore, should be of interest to Canadian accounting policy makers as they provide ex-ante evidence on the potential usefulness of mandating firms to report comprehensive income and the components of other comprehensive income in their financial statements.

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.     

Taxation of Interest Income

Why is interest income taxed so much more heavily than other forms of capital income? This differential tax treatment has generated substantial tax arbitrage, resulting in lower tax revenue, efficiency costs, and apparently net gains to rich borrowers and net losses to poor lenders, together suggesting that this tax treatment makes no sense on welfare grounds. In examining this argument more formally, this paper reveals two omitted considerations that can help explain the existing tax treatment. First, the forecasted increase in the market interest rate results in a redistribution from rich borrowers to poor lenders. Yet this redistribution comes at no marginal efficiency cost, starting from a situation with no distortions to portfolio choice, so at the margin dominates further redistribution through the income tax. In addition, information about an individual's portfolio choice reveals information about her earnings ability, even controlling for observed labor income, if those who are more able tend to be less risk averse. By making use of this extra information about earnings ability, the tax system can be better tailored to redistribute from able to less able, for any given efficiency cost.     

Voluntary disclosure of operating income

This study investigates whether New Zealand firms’ voluntary disclosure of operating income, which is also known as earnings before interest and tax, in the income statement is related to the investment opportunity set. New Zealand provides an ideal setting to examine this because New Zealand generally accepted accounting principles do not require the disclosure of operating income as an intermediate income number in arriving at net income (earnings) in the income statement. We hypothesize and find evidence that firms with high assets‐in‐place and high leverage are more likely to voluntarily disclose operating income/earnings before interest and tax. However, the assets‐in‐place finding is sensitive to alternative measures of the investment opportunity set.

Variable Rate Debt Instruments and Corporate Debt Policy

Sustained high rate of inflation has led to the creation of debt instruments with variable interest rate. The availability of these debt instruments presents management with the problem of the choice of the optimal debt portfolio. This paper deals with this problem assuming a given, and optimal, debt to equity ratio. Given expected monetary value maximization, an efficient frontier is derived in terms of the expected net income and probability of bankruptcy, where net income is defined as operating income minus debt repayment. This efficient frontier is shown to be also mean-variance efficient. It is also shown that in most cases the optimal debt portfolio includes more than one debt instrument. In other words, the firm will avoid the policy of minimizing the expected cost of its debt repayments or the policy of minimizing the costs of bankruptcy. The optimal solution itself is affected by market variables like the relative expected cost of different debt instruments and by firm specific variables like the variability of its operating income stream, and the covariance between the operating income and the debt repayments.     

Comparing the Value Relevance of Two Operating Income Measures

Prior research has shown that pro-forma (recurring operating) earnings reported by managers and analysts are more value relevant than GAAP net income. Since GAAP net income contains many non-operating items that reduce its value relevance compared to operating earnings, comparing the value relevance of GAAP net income with operating earnings unduly favors operating earnings. We show that operating earnings reported by managers and analysts are more value relevant than a measure of operating earnings derived from firms' financial statements, as reported by Standard and Poor's. Our evidence is important because it indicates that operating earnings reported by managers and analysts contain value relevant information beyond that provided by operating earnings obtained by sophisticated users from firms' financial statements.     

Quantifying the components of the banks’ net interest margin

Using unique data sets on German banks, we decompose their net interest margin and quantify the different components by estimating the costs of the various functions they perform. We investigate three major functions: liquidity and payment management for customers, bearing credit risk, and term transformation. For 2013, the costs of liquidity and payment management correspond, in the median, to 47% of the net interest margin, with bearing of credit risk and earnings from term transformation accounting for 12 and 37%, respectively.     

Credit Risk in Two Institutional Regimes: Spanish Commercial and Savings Banks

Although credit risk is an important factor that financial institutions must cope with, the determinants of bank problem loans have been little studied. Using panel data, we compare the determinants of problem loans of Spanish commercial and savings banks in the period 1985–1997, taking into account both macroeconomic and individual bank level variables. The GDP growth rate, firms, and family indebtedness, rapid past credit or branch expansion, inefficiency, portfolio composition, size, net interest margin, capital ratio, and market power are variables that explain credit risk. However, there are significant differences between commercial and savings banks, which confirm the relevance of the institutional form in the management of credit risk. Our findings raise important bank supervisory policy issues: the use of bank level variables as early warning indicators, the advantages of bank mergers from different regions, and the role of banking competition and ownership in determining credit risk.

Earnings management and the allocation of net periodic pension costs to interim periods

We examine the pattern of reported quarterly net periodic pension costs. Quarterly pension costs are one of the largest single expense items for firms with pension plans (around 15% of income before extraordinary items in our sample). Under ASC 270, net pension costs should be recognized as incurred, or as the benefit provided by the expense is realized. We find that over the period of 2004–2010, there is significant variation in the amount of quarterly pension cost firms report. In addition, we find that income-increasing changes in pension costs are significantly associated with meeting or beating analysts' forecasts in a given quarter. We also show that income-decreasing changes to net periodic pension costs that would cause a firm to miss its earnings forecast are extremely rare. Finally, we find evidence that income-increasing and income-decreasing changes in quarterly pension costs are “settled up” in the fourth quarter (e.g., they are reversed).
