Fiscal Consequences of Paying Interest on Reserves

We review the role of the central bank's balance sheet in a textbook monetary model and explore what changes if the central bank is allowed to pay interest on its liabilities. When the central bank (CB) cannot pay interest, away from the zero lower bound its (real) balance sheet is limited by the demand for money. Furthermore, if securities are not marked to market and the central bank holds its bonds to maturity, it is impossible for the CB to make losses, and it always obtains profits from being a monopoly provider of money. When the option of paying interest on liabilities is allowed, the limit on the CB's balance sheet is lifted. In this case, the CB is free to take on interest‐rate risk – for example, by buying long‐term securities and financing those purchases with short‐term debt that pays the market interest rate. This is a risky enterprise that can lead to additional profits but also to losses. To the extent that losses exceed the profits of the monopoly operations, the CB faces two options: either it is recapitalised by Treasury or it increases its monopoly profits by raising the inflation tax.     

Synthetic Floating‐Rate Debt: An Example of an Asset‐Driven Liability Structure

An asset‐driven liability (ADL) structure is analogous to a liability‐driven investment (LDI) strategy. In both cases, the intent is to reduce the risk arising from a mismatch of assets and liabilities by aligning the interest rate sensitivity of cash flows on both sides of the balance sheet. Increasingly, defined‐benefit pension plans have adopted LDI strategies that reduce their equity assets and increase the average duration of their debt assets to better match the typical long duration of their retirement obligations to its employees. To illustrate the concept of ADL, the authors use the example of a corporate issue of traditional fixed‐rate debt that is transformed into synthetic floating‐rate debt using an interest rate swap (in which the corporation receives the fixed rate on the swap and pays at money market reference rate like three‐month LIBOR). The use of such long‐term, floating‐rate debt reduces interest rate risk when the firm has operating revenues that are positively correlated to the business cycle. However, a problem arises in that there is limited demand for such debt securities from institutional investors, many of which, because of LDI guidelines, prefer long‐term, fixed‐rate securities. Derivatives provide a way of resolving this mismatch between issuer and investor interests. In the article, the authors present a detailed example of the cash flows on the “receive‐fixed” interest rate swap (and its valuation for financial reporting) to show how the synthetic ADL debt structure obtains the desired outcome.     

Inflation Expectations and Risk Premiums in an Arbitrage‐Free Model of Nominal and Real Bond Yields

Differences between yields on comparable‐maturity U.S. Treasury nominal and real debt, the so‐called breakeven inflation (BEI) rates, are widely used indicators of inflation expectations. However, better measures of inflation expectations could be obtained by subtracting inflation risk premiums (IRP) from the BEI rates. We provide such decompositions using an affine arbitrage‐free model of the term structure that captures the pricing of both nominal and real Treasury securities. Our empirical results suggest that long‐term inflation expectations have been well anchored over the past few years, and IRP, although volatile, have been close to zero on average.     

A Simple Approach to Valuing Risky Fixed and Floating Rate Debt

We develop a simple approach to valuing risky corporate debt that incorporates both default and interest rate risk. We use this approach to derive simple closed-form valuation expressions for fixed and floating rate debt. The model provides a number of interesting new insights about pricing and hedging corporate debt securities. For example, we find that the correlation between default risk and the interest rate has a significant effect on the properties of the credit spread. Using Moody's corporate bond yield data, we find that credit spreads are negatively related to interest rates and that durations of risky bonds depend on the correlation with interest rates. This empirical evidence is consistent with the implications of the valuation model.     

INFLATION,SECURITY VALUES,AND RISK PREMIA

The impact of stochastic inflation on the cross-sectional structure of nominal securities yields is examined. The analysis indicates that equilibrium required returns on debt and equity securities are affected differently by inflation and that the “Fisher Effect” is more likely to hold for equity returns than for debt yields. Implications for empirical investigations of portfolio performance and the real interest rate are explored.     

The Term Structure of Real Rates and Expected Inflation

Changes in nominal interest rates must be due to either movements in real interest rates, expected inflation, or the inflation risk premium. We develop a term structure model with regime switches, time‐varying prices of risk, and inflation to identify these components of the nominal yield curve. We find that the unconditional real rate curve in the United States is fairly flat around 1.3%. In one real rate regime, the real term structure is steeply downward sloping. An inflation risk premium that increases with maturity fully accounts for the generally upward sloping nominal term structure.     

The impact of hedging on the market value of equity

We examine the annual stock performance of firms that disclose the use of derivatives to hedge over the period 1995 to 1999. We find that only 21.6% of publicly traded U.S. corporations in our sample hedged with derivative instruments over this period and their use is concentrated in the larger companies. Similar to other studies we find that when derivatives are used, interest rate and currency securities are used much more frequently than commodity products. Our sample of 1308 companies that hedge outperforms other securities by 4.3% per year on average over our sample period. This result is robust to several alternative methods of estimating abnormal returns. When we segment performance by the type of hedge used, however, we find that the over-performance is due entirely to larger firms that hedge currency. We find no abnormal returns for firms hedging either interest rates or commodities. The abnormal returns in firms hedging currency is robust to alternative models that seek to control for exchange rate fluctuations and global equity returns; however, we find no significant abnormal returns to currency hedgers when using an augmented model that controls for the role of intangible assets.     

Hedge Fund Involvement in Convertible Securities

Convertible arbitrage hedge funds combine long positions in convertible securities with short positions in the underlying stock. In effect, hedge funds use their knowledge of the borrowing and short‐sale market to hedge themselves while distributing equity exposure to a large number of well‐diversified investors through their short positions. The authors argue that many “would‐be” equity issuers that would otherwise pay high costs in a secondary equity issue choose instead to issue convertible debt to hedge funds that in turn distribute equity exposure to institutional investors. This allows companies to receive “equity‐like” financing today at lower cost than a secondary equity offering. The authors' findings also suggest that more convertibles will be privately placed with hedge funds when issuer and market conditions suggest that shorting costs will be lower.     

Does Risk Management Add Value? A Survey of the Evidence

The fact that 92% of the world's 500 largest companies recently reported using derivatives suggests that corporate managers believe financial risk management can increase shareholder value. Surveys of finance academics indicate that they too believe that corporate risk management is, on the whole, a valueadding activity. This article provides an overview of almost 30 years of broadbased, stock‐market‐oriented academic studies that address one or more of the following questions:

• ? Are interest rate, exchange rate, and commodity price risks reflected in stock price movements?
• ? Is volatility in corporate earnings and cash flows related in a systematic way to corporate market values?
• ? Is the corporate use of derivatives associated with reduced risk and higher market values?

The answer to the first question, at least in the case of financial institutions and interest rate risk, is a definite yes; all studies with this focus find that the stock returns of financial firms are clearly sensitive to interest rate changes. The stock returns of industrial companies exhibit no pronounced interest rate exposure (at least as a group), but industrial firms with significant cross‐border revenues and costs show considerable sensitivity to exchange rates (although such sensitivity actually appears to be reduced by the size and geographical diversity of the largest multinationals). What's more, the corporate use of derivatives to hedge interest rate and currency exposures appears to be associated with lower sensitivity of stock returns to interest rate and FX changes. But does the resulting reduction in price sensitivity affect value—and, if so, how? Consistent with a widely cited theory that risk management increases value by limiting the corporate “underinvestment problem,” a number of studies show a correlation between lower cash flow volatility and higher corporate investment and market values. The article also cites a small but growing group of studies that show a strong positive association between derivatives use and stock price performance (typically measured using price‐to‐book ratios). But perhaps the nearest the research comes to establishing causality are two studies—one of companies that hedge FX exposures and another of airlines' hedging of fuel costs—that show that, in industries where hedging with derivatives is common, companies that hedge outperform companies that don't.     

RISK MANAGEMENT FOR MIDDLE MARKET COMPANIES

This article reinforces the message of the one immediately preceding by showing that small to medium‐sized firms have even stronger (non‐tax) motives for hedging risks than their large corporate counterparts. Although middle market companies have traditionally been viewed as less sophisticated than their larger corporate counterparts in the risk management arena, the authors suggest that such companies have become increasingly receptive to new hedging strategies using derivative products. When used appropriately, such products allow companies to stabilize their periodic operating cash flow by eliminating specific sources of volatility such as fluctuations in interest rates, exchange rates, and commodity prices. Smaller companies recognize that a single swing in a budgeted cost can have a catastrophic effect on an entire budget, whereas a larger company can more easily absorb such a cost. Moreover, because the principal owners of mid‐sized firms often have a substantial part of their net worth tied up in the business, they are likely to have a far stronger interest than typical outside shareholders in using risk management to reduce the volatility of corporate profits and firm value. Perhaps most important to owners whose firms rely on debt financing, the greater cash flow stability resulting from active risk management significantly reduces the possibility of financial distress or bankruptcy. In this article, three representatives of Bank of America's risk management practice discuss three different exposures faced by middle market companies—those arising from changes in interest rates, foreign exchange rates, and commodity prices—and show how these risks can be managed with derivatives. Besides shielding companies from financial trouble, risk management is also likely to improve their access to the money and capital markets. By protecting the firm's access to capital, risk management increases the odds that the firm will not be forced to pass up good investment opportunities because of capital constraints or fear of getting into financial difficulty.     

Interest rate differentials on short-term securities and rational expectations of inflation

This paper tests a theorem to the effect that the difference in nominal interest rates between two securities of the same maturity but different risk is an increasing linear function of the expected rate of inflation. When inflation is modelled in a way which is rational in the sense of Muth, the evidence is highly consistent with the theorem's inferences. Estimates are also obtained of the real risk premiums that certain types of securities generate over the three-month treasury bill rate (which is assumed to be risk-free). These range from three basis points for three-month finance paper to 16 basis points for three-month Eurodollar deposits.     

Interest Rate Swaps and Corporate Financing Choices

This paper describes the firm's decision to borrow short-term versus long-term and shows how the introduction of interest rate swaps affects this choice. The model shows that in the absence of a swap market, interest rate uncertainty can lead firms to substitute long-term for short-term financing. However, when swaps exist, there is a tendency for firms that expect their credit quality to improve to borrow short-term and use swaps to hedge interest rate risk. The model suggests that, while the demand for fixed for floating swaps is enhanced, the demand for floating for fixed swaps is reduced by the presence of asymmetric information.     

Discussion of “Hedge commitments and agency costs of debt: evidence from interest rate protection covenants and accounting conservatism”

Beatty, Petacchi, and Zhang investigate the role of two hedge commitment mechanisms??interest rate protection covenants and accounting conservatism??in reducing agency costs of debt. Using a large sample of syndicated loan agreements, they provide evidence that borrowers required to hedge interest rate risk through interest rate protection covenants receive lower interest rate charges. However, borrowers who voluntarily hedge interest rate risks receive lower rates only if they implement conservative financial reporting. The authors conclude that the benefits of hedging are realized only when borrowers can credibly commit to maintain hedge positions once a syndicated loan is issued. While the evidence provided by the authors is novel and interesting, I argue that the empirical assessment of hedge benefits is more complex. In addition, there are still some important open issues left unanswered that could be tackled by future research.     

Inflation Risk in Corporate Bonds

We argue that corporate bond yields reflect fears of debt deflation. When debt is nominal, unexpectedly low inflation increases real liabilities and default risk. In a real business cycle model with optimal but infrequent capital structure choice, more uncertain or procyclical inflation leads to quantitatively important increases in corporate log yields in excess of default‐free log yields. A panel of credit spread indexes from six developed countries shows that credit spreads rise by 14 basis points if inflation volatility or the inflation‐stock correlation increases by one standard deviation.     

Hedge commitments and agency costs of debt: evidence from interest rate protection covenants and accounting conservatism

We provide large sample evidence that credible hedge commitments reduce the agency costs of debt and that accounting conservatism enhances hedge commitments. We examine 2,338 bank loans entered into by 263 mandatory derivative users that are contractually obligated by interest rate protection covenants, 709 voluntary derivative users, and 1,366 non-users. We show that loan contracts are more likely to include interest rate protection covenants when borrowers are less likely to maintain the hedge position once the financing is completed. We find that borrowers who credibly commit to hedge using these covenants significantly reduce their interest rates. While we do not find an average interest savings for voluntary derivative users, we do find a reduction in their loan rates when they practice conservative financial reporting. Our results suggest that accounting conservatism helps borrowers resolve shareholder-creditor conflicts by committing to maintain their hedge positions after completing debt financing.     

SELECTIVE HEDGING OF BANK ASSETS WITH TREASURY BILL FUTURES CONTRACTS

The recent volatility of interest rates, the associated profit pressures imposed on banks, and the surge in the development of new contracts have stimulated a desire to understand and apply financial futures hedging to banking operations. This paper models interest rate futures contracts in a theory of bank behavior to illustrate the hedging of bank loans as well as government securities. The model predicts the hedge will be greater (1) the greater the expected rise in interest rates and (2) the greater the effect of disintermediation on bank deposits. A simulation of the financial futures trading strategy is reported for banks of various asset sizes using data from the Eleventh Federal Reserve District. Depending on bank risk aversion and interest rate expectations, hedging the bank's total interest rate exposure with T-bill futures reduces the variability of unhedged profits by 80 percent.     

The Effects of Anticipated Inflation on Housing Market Equilibrium

An increase in the anticipated rate of inflation causes distortions in the housing market due to a nonindexed tax system. Since nominal rather than real interest payments are tax deductible, an increase in inflation decreases the aftertax cost of capital for homeowners, which in turn increases the demand for housing and increases its real price. This tax gain is shown to be larger for rental housing than for owner-occupied housing. In a competitive market, this implies that although the real price of housing increases with a rise in anticipated inflation, real rental rates fall.     

Structural models of credit risk are useful: Evidence from hedge ratios on corporate bonds

Structural models of credit risk provide poor predictions of bond prices. We show that, despite this, they provide quite accurate predictions of the sensitivity of corporate bond returns to changes in the value of equity (hedge ratios). This is important since it suggests that the poor performance of structural models may have more to do with the influence of non-credit factors rather than their failure to capture the credit exposure of corporate debt. The main result of this paper is that even the simplest of the structural models [Merton, R., 1974. On the pricing of corporate debt: the risk structure of interest rates. Journal of Finance 29, 449–470] produces hedge ratios that are not rejected in time-series tests. However, we find that the Merton model (with or without stochastic interest rates) does not capture the interest rate sensitivity of corporate debt, which is substantially lower than would be expected from conventional duration measures. The paper also shows that corporate bond prices are related to a number of market-wide factors such as the Fama-French SMB (small minus big) factor in a way that is not predicted by structural models.     

Public Information Arrival and the Fisher Effect in Emerging Markets: Evidence from Stock and Bond Markets in Turkey

We examine the impact of inflation on nominal stock returns and interest rates in Turkey's emerging economy, which has a moderately high, persistent, and volatile inflation rate. Empirical evidence indicates that Turkey's inflation increased more than nominal stock returns and interest rates, implying that real returns to investors declined during our sample period. Among the different sector indexes we study, the financials sector serves as the best hedge against expected inflation, and the Fisher effect appears to hold only for this sector. We also find that public information arrival plays an important role, especially in the stock market.     

放松利率管制、利润率均等化与实体企业“脱实向虚”

本文以我国贷款利率上下限放开为准自然实验,基于产权性质差异构造双重差分模型,实证考察放松利率管制如何影响实体企业金融化。研究发现:放松贷款利率下限管制能够显著抑制非国有企业金融化程度,而放松贷款利率上限管制则无显著作用,支持了“市场套利观”。机制检验发现贷款利率下限管制的放松显著抑制企业债务成本对企业利润的侵蚀作用;拓展性检验还发现对于盈利能力越强、规模越大以及市场竞争压力越小的公司,放松贷款利率下限管制对抑制非国有企业金融化的作用更显著。以上研究结论表明,实体经济与虚拟经济间的利润率差距是我国实体企业金融化的重要诱因,金融市场化改革有助于抑制实体企业金融化、改善“实体经济”与“虚拟经济”间的良性互动关系,从而助推实体经济的健康发展。
