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.     

An Investment Management Methodology for Publicly Held Property/Casualty Insurers

Investment officers of publicly held property/casualty companies wrestle with the question of how best to contribute to shareholder value. Should they view themselves as managers of a closed‐end investment company that happens to be funded by insurance underwriting? Or should they instead be investing funds primarily to defease the firm's liabilities and thus support the operations of a company whose principal value derives from its insurance activities? The authors of this article suggest that the investment policy of most insurance companies should have two primary objectives: (1) immunizing insurance reserves with a fixed‐income portfolio and (2) earning “abnormal returns” on surplus in “a responsible and disciplined” way. The latter means adhering to an asset allocation approach that takes account of the risk‐reward tradeoffs presented by a broad variety of investment types as well as the accounting treatment of investment income. Both accounting and economic considerations lead the authors to suggest that after‐tax net investment income (“NII”), as defined by U.S. GAAP, is the best benchmark of performance. While focusing mainly on the fixed income part of the portfolio, the authors suggest active management and portfolio approaches that aim to produce a growing, but relatively stable NII. Consistent with GAAP's treatment of NII (which includes interest income but excludes most capital gains) as “recurring income,” the authors argue that the market appears to assign significantly higher multiples to NII than to other sources of reported income.     

The role of securitization in bank liquidity and funding management

This paper studies the role of securitization in bank management. I propose a new index of “bank loan portfolio liquidity” which can be thought of as a weighted average of the potential to securitize loans of a given type, where the weights reflect the composition of a bank loan portfolio. I use this new index to show that by allowing banks to convert illiquid loans into liquid funds, securitization reduces banks' holdings of liquid securities and increases their lending ability. Furthermore, securitization provides banks with an additional source of funding and makes bank lending less sensitive to cost of funds shocks. By extension, the securitization weakens the ability of the monetary authority to affect banks' lending activity but makes banks more susceptible to liquidity and funding crisis when the securitization market is shut down.     

Duration gaps with futures and swaps for managing interest rate risk at depository institutions

Duration gaps for depository institutions are derived for economic net worth, economic net income, and book value interest income. The duration gaps previously constructed for on-balance sheet accounts are expanded to off-balance sheet accounts, including futures contracts and swap agreements. These expanded duration gaps are indicators of the sensitivity of the market value of net worth and income measures to interest rate fluctuations. Managers of depository institutions can establish these duration gaps as targets and can utilize futures markets and swap agreements to affect the target values. The developments in this article are based on a single factor model of interest rate movements, but the results can be extended.The work in this article is based partly on Bierwag and Kaufman (1989), a study prepared for and funded by the Federal Home Loan Bank Board. We have benefited from comments of discussants and participants at presentations at HEC Jouy-en-Josas, the meetings of the European Finance Association, and seminars at the University of Delaware, Loyola University of Chicago, the Federal Reserve Bank of Chicago, Florida State University, and the University of Illinois, Chicago.     

Do Investment Banks Have Incentives to Help Clients Make Value‐Creating Acquisitions?

Many have long suspected that investment banks, when advising corporate clients on potential acquisitions, have strong incentives just to “get the deal done” with little if any motive for urging clients to walk away from “bad” deals. The incentive to complete deals comes from compensation arrangements in which the bulk of the bankers' fees depend upon completion of the deals. Several earlier studies have provided support for this suspicion by reporting findings that show banks' market shares of advisory services depending mainly on two variables—their previous market shares and their deal completion rate—with little if any connection to the value created (or destroyed) for their clients' shareholders. In their recently published study, the authors revisit that relationship and reach a number of different conclusions: (1) advisors in acquisitions that create more value for clients are more likely to be chosen for future deals; (2) the changes in bankers' advisory market shares are strongly related to the value created for prior clients; and (3) the changes in banks' market values are positively correlated with the value created for their acquirer clients. In sum, the findings suggest that banks have significant market‐related incentives to advise their clients to pursue value‐creating acquisitions and to avoid deals likely to reduce their market values.     

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.     

The interest rate pass-through in the euro area during the sovereign debt crisis

We investigate the pass-through of monetary policy to bank lending rates in the euro area during the sovereign debt crisis, in comparison to the pre-crisis period. We make the following contributions. First, we use a factor-augmented vector autoregression, which allows us to assess the responses of a large number of country-specific interest rates and spreads. Second, we analyze the effects of monetary policy on the components of the interest rate pass-through, which reflect banks' funding risk (including sovereign risk) and markups charged by banks over funding costs. Third, we not only consider conventional but also unconventional monetary policy. We find that while the transmission of conventional monetary policy to bank lending rates has not changed with the crisis, the composition of the pass-through has changed. Specifically, expansionary conventional monetary policy lowered sovereign risk in peripheral countries and longer-term bank funding risk in peripheral and core countries during the crisis, but has been unable to lower banks' markups. This was not, or not as much, the case prior to the crisis. Unconventional monetary policy helped decreasing lending rates, mainly due to large shocks rather than a strong propagation.     

Deregulation, Deposit Markets, and Banks' Costs of Funds

Deposit interest rate deregulation and financial service innovation have led to dramatic changes in large banks' deposit composition. This paper presentes a statistical cost analysis of changes in unit costs faced by banks under comprehensive financial deregulation. The results of this paper show that the unit cost of retail deposits-demand and passbook savings deposits-has increased relative to wholesale deposits-federal funds, certificates of deposit, and money market time deposits. We show, contrary to conventional wisdom, that changes in unit costs have been caused by processing costs rather than by interest expenses.     

Noninterest Income and Financial Performance at U.S. Commercial Banks

Noninterest income now accounts for over 40% of operating income in the U.S. commercial banking industry. This paper demonstrates a number of empirical links between bank noninterest income, business strategies, market conditions, technological change, and financial performance between 1989 and 2001. The results indicate that well‐managed banks expand more slowly into noninterest activities, and that marginal increases in noninterest income are associated with poorer risk‐return tradeoffs on average. These findings suggest that noninterest income is coexisting with, rather than replacing, interest income from the intermediation activities that remain banks' core financial services function.     

Bank management of the net interest margin: new measures

We decompose the change in banks’ net interest margin into a change in market-wide bank rates and a change in balance-sheet composition. The usefulness of this decomposition is illustrated for a detailed data set of German bank balance sheets, broken down into different maturities, creditors and borrowers, and degrees of liquidity. Our main findings are as follows. (1) Changes in market-wide bank rates have a much higher explanatory power for net interest margins than changes in balance-sheet composition. (2) On average, banks employ interest rate derivatives to hedge on-balance risk since changes in market-wide rates affect the net interest margin less strongly for derivatives users than for non-users. (3) When risk taking becomes more lucrative, derivatives users tend to increase their on-balance exposure more than do non-users.     

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.     

INTEREST RATE RISK,MARKET VALUE,AND HEDGING FINANCIAL PORTFOLIOS

This paper derives theoretical hedge ratios for the financial portfolio that preserve its present value in the presence of interest rate risk. From a practical point of view and for any given portfolio, the existence of the financial futures market allows the investor to employ any of a number of different hedges, each of which approximately satisfies the theoretical condition. The theory indicates that wealth-preserving hedges depend on the interest elasticities (durations) of the spot assets and liabilities contained in the portfolio, portfolio leverage, and the interest elasticity (duration) of the financial instrument underlying the futures contract that is employed in constructing the hedge. Also, hedges designed to maintain net interest margin or net cash flow do not minimize exposure to interest rate risk.     

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.     

The determinants of net interest income in the Mexican banking system: An integrated model

This paper analyzes net interest income in the Mexican banking system over the period 1993–2005. Taking as reference the seminal work by Ho and Saunders [Ho, T., Saunders, A., 1981. The determinants of banks interest margins: theory and empirical evidence. Journal of Financial and Quantitative Analysis XVI (4), 581–600] and subsequent extensions by other authors, our study models the net interest margin simultaneously including operating costs and diversification and specialization as determinants of the margin. The results referring to the Mexican case show that its high margins can be explained mainly by average operating costs and by market power. Although non-interest income has increased in recent years, its economic impact is low.     

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.     

The Validity of the Economic Value Added Approach: an Empirical Application

This study investigates the relative explanatory power of the Economic Value Added (EVA) model with respect to stock returns and firms' market value, compared to established accounting variables (e.g. net income, operating income), in the context of a small European developing market, namely the Athens Stock Exchange, in its first market‐wide application of the EVA measure. Relative information content tests reveal that net and operating income appear to be more value relevant than EVA. Additionally, incremental information tests suggest that EVA unique components add only marginally to the information content of accounting profit. Moreover, EVA does not appear to have a stronger correlation with firms' Market Value Added than the other variables, suggesting that – for our Greek dataset – EVA, even though useful as a performance evaluation tool, need not necessarily be more correlated with shareholder's value than established accounting variables.     

Capital flows to emerging market economies: A brave new world?

We examine the determinants of net private capital inflows to emerging market economies (EMEs) since 2002. Our main findings are: First, growth and interest rate differentials between EMEs and advanced economies and global risk appetite are statistically and economically important determinants of net private capital inflows. Second, there have been significant changes in the behavior of net inflows from the period before the recent global financial crisis to the post-crisis period, especially for portfolio inflows, partly explained by the greater sensitivity of such flows to interest rate differentials since the crisis. Third, capital controls introduced in recent years do appear to have discouraged both total and portfolio net inflows. Finally, we find positive effects of unconventional U.S. monetary policy on EME inflows, especially portfolio inflows. Even so, U.S. unconventional policy is one among several important factors influencing flows.     

Investment Bank Reputation,Information Production,and Financial Intermediation

We model reputation acquisition by investment banks in the equity market. Entrepreneurs sell shares in an asymmetrically informed equity market, either directly, or using an investment bank. Investment banks, who interact repeatedly with the equity market, evaluate entrepreneurs' projects and report to investors, in return for a fee. Setting strict evaluation standards (unobservable to investors) is costly for investment banks, inducing moral hazard. Investment banks' credibility therefore depends on their equity-marketing history. Investment banks' evaluation standards, their reputations, underwriter compensation, the market value of equity sold, and entrepreneurs' choice between underwritten and nonunderwritten equity issues emerge endogenously.     

Fiscal consolidations and bank balance sheets

We empirically investigate the effects of fiscal policy on bank balance sheets, focusing on episodes of fiscal consolidation. To this aim, we employ a very large data set of individual banks' balance sheets, combined with a newly compiled data set on fiscal consolidations. We find that standard capital adequacy ratios such as the Tier-1 ratio tend to improve following episodes of fiscal consolidation: for the median bank in our sample, a 1% of GDP fiscal consolidation increases the Tier-1 capital ratio by around 1.5 percentage points over two years. Our results suggest that this improvement results from a portfolio re-balancing from private to public debt securities which reduces the risk-weighted value of assets. In fact, if fiscal adjustment efforts are perceived as structural policy changes that improve the sustainability of public finances and, therefore, reduce credit risk, the banks' demand for government securities should increase relative to other assets.     

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.
