Information Risk in TIPS Market: An Analysis of Nominal and Real Interest Rates

This study investigates the presence of information risk in two closely linked interest rate securities traded in separate markets: the nominal interest rate observed in the Treasury bond market and the real interest rate observed in the relatively new Treasury Inflation-Protected Securities (TIPS) market. We find that information flows unilaterally from the Treasury bond market to the TIPS market with a one-day lag. The information risk arising from asymmetric information flows may cause less informed traders to demand a higher rate of return (OHara, 2003). Our study provides an empirical explanation of why the TIPS yield has been relatively high throughout its nascent trading history.     

ARE TREASURY INFLATION PROTECTED SECURITIES REALLY TAX DISADVANTAGED?

In 1997, the U.S. Treasury introduced Inflation Protected Securities, commonly known as TIPS. Several in the finance field have since described these securities as “tax disadvantaged” relative to conventional securities, leading to serious questions regarding their appropriateness outside of tax‐deferred accounts. In this article, we develop a framework that demonstrates that at least in a real sense the tax treatment of TIPS is trivially different from that of conventional Treasury securities. Moreover, empirically we find evidence that TIPS generally have after‐tax yields comparable to, if not exceeding, conventional fixed‐rate Treasury securities. We also show that TIPS have generally outperformed matched‐maturity conventional Treasury securities in terms of after‐tax rates of return.     

The nominal duration of TIPS bonds

This paper studies the price responsiveness (effective duration) of U.S. government issued inflation-indexed bonds, known by the acronym TIPS (Treasury Inflation-Protected Securities), to changes in nominal interest rates, real interest rates, and expected inflation. Using the TIPS pricing formula derived by Laatsch and Klein [Q. Rev. Econ. Finance 43 (2002) 405], we first confirm that TIPS bonds have zero sensitivity to changes solely in expected inflation. By changes solely in expected inflation, we mean that the real rate remains unchanged and the nominal rate changes in accordance with the established Fisher [Publ. Am. Econ. Assoc. 11 (1896)] effect. We show that the first derivative of the TIPS price is zero whenever the real rate is held constant. Thus, the first partial derivative of the TIPS bond pricing formula with respect to expected inflation is zero and the first partial derivative of the TIPS bond price with respect to nominal rates is also zero, given, in each case, that we hold the real rate constant. We then temporarily shift the analysis to zero-coupon TIPS bonds and zero-coupon ordinary Treasury bonds. We prove that the nominal duration of zero-coupon TIPS bonds equals that of zero-coupon ordinary Treasury bonds when the real rate changes but expected inflation is held constant.However, if expected inflation changes and the change in the nominal rate does not yield a constant real rate, zero-coupon TIPS prices will change and they will change by a smaller percentage than will zero-coupon ordinary Treasury bonds. We analyze TIPS responsiveness to changes in nominal rates under such conditions. We derive an approximation to effective duration that demonstrates that the effective durations of various maturity zero-coupon TIPS bonds are approximately linear functions in time to maturity of the effective duration of the one-year zero-coupon TIPS bond, ceteris paribus.Nominal effective duration of TIPS bonds is certainly of interest to fixed income portfolio managers that might have a desire to include such bonds in their portfolio. After all, the greater portion of a typical fixed income portfolio is in traditional, noninflation protected bonds whose major risk exposure is to changes in nominal rates. To properly assess the role of TIPS bonds in the portfolio, portfolio managers need information as to how TIPS bonds respond to the changes in nominal rates that are driving the price behavior of the bulk of the portfolio's assets. Prior to concluding the paper, we demonstrate how portfolio managers can calculate the nominal durations of coupon TIPS bonds using the zero-coupon duration formula we derive.     

A MULTIFACTOR MODEL OF THE QUALITY OPTION IN TREASURY FUTURES CONTRACTS

The values of quality options in Treasury futures contracts are set relative to the prices of all coupon bonds in their respective deliverable sets. As a result, any model used to value the quality option should set its price relative to the set of observed bond prices. This requirement rules out the use of most simple equilibrium models that represent all bond prices in terms of a finite number of state variables. We use the two-factor Heath-Jarrow-Morton model, which permits claims to be priced relative to observable bond prices, to investigate the potential value of the quality option in Treasury bond and note futures. We show that the quality option has significantly more value in a two-factor interest rate economy than in a single-factor economy, and that ignoring it could lead to significant mispricing.     

Managerial Behavior and the Link between Stock Mispricing and Corporate Investments: Evidence from Market‐to‐Book Ratio Decomposition

We examine the impact of mispricing on corporate investments and its components: capital expenditures, research and development, acquisitions, and asset sales. By decomposing the market‐to‐book ratio into mispricing and growth components, we show that corporate investments are linked to mispricing through market‐timing and catering, after controlling for growth and financial slack. This investment‐mispricing link is more pronounced in financially constrained firms and in firms with short‐horizon shareholders. Overall, our study indicates that the sensitivity of investments to mispricing is a function of the nature of mispricing, the type of investment, and the firm's characteristics.     

Do investors misprice components of net periodic pension cost?

We examine whether and how investors misprice the components of net periodic pension cost under SFAS No. 87 and 158. We find that investors appear to have difficulty in understanding the transitory feature of other net periodic pension cost (PPOPCC) and thus overestimate its persistence, which in turn leads to the mispricing of PPOPCC in the pre‐158 period. We also find that SFAS No. 158 appears to reduce the mispricing of PPOPCC, suggesting a positive effect of SFAS No. 158 on investors' valuation of pension items in the income statement. Additional analysis suggests that investors also overestimate the persistence of, and thus misprice, pension‐related cash flows and accruals in the pre‐158 period and that SFAS No. 158 reduces the mispricing of pension‐related cash flows and accruals.     

The effect of macroeconomic news on beliefs and preferences: Evidence from the options market

We examine the effect of regularly scheduled macroeconomic announcements on the beliefs and preferences of participants in the U.S. Treasury market by comparing the option-implied state-price densities (SPDs) of bond prices shortly before and after the announcements. We find that the announcements reduce the uncertainty implicit in the second moment of the SPD regardless of the content of the news. The changes in the higher-order moments, in contrast, depend on whether the news is good or bad for economic prospects. We explore three alternative explanations for our empirical findings: relative mispricing, changes in beliefs, and changes in preferences. We find that our results are consistent with time-varying risk aversion.     

Salomon brothers and the May 1991 Treasury auction: Analysis of a market corner

In May 1991, the Treasury sold $12.29 billion in two-year notes. Through improper bidding, Salomon Brothers gained control of at least 86 percent of the issue. This study investigates the impact of Salomon's attempted corner by examining the postauction price behaviour of the two-year note. Based on a no-arbitrage relation, the results show that the two-year note was substantially overpriced for approximately six weeks following the auction. The typical mispricing during this period is estimated at 0.16 to 0.25 percent of par. In dollar terms, the aggregate misvaluation averaged $20–$30 million, and, by controlling the supply of the issue, Salomon stood to gain substantially from the squeeze.     

What went wrong? The Puerto Rican debt crisis,the “Treasury Put,” and the failure of market discipline

What went wrong? Why did seemingly rational, forward-looking bond investors continue to purchase Puerto Rican debt with only a modest risk premium? Why did financial markets fail to exercise market discipline and restrict capital flows to Puerto Rico?This paper examines the hypothesis that investors believed Puerto Rican debt was implicitly insured by the U.S. government by studying a rare situation where this “Treasury Put” was extinguished. The expectation of a federal bailout was perfectly reasonable given past behavior by the federal government. Evaluating the Treasury Put hypothesis with a minimal set of assumptions is possible given three unique features of the economic environment. The key feature is an exogenous “seismic shock” – the non-bailout of the city of Detroit in 2013 that effectively extinguished the Treasury Put, estimated in this paper as 350 basis points. Institutional reforms that would eliminate the Treasury Put are considered, but none are found satisfactory. How to extinguish the Treasury Put on an ongoing basis in a democratic society remains an open question.     

The U.S. Treasury Buyback Auctions: The Cost of Retiring Illiquid Bonds

We study an important recent series of buyback auctions conducted by the U.S. Treasury in retiring $67.5 billion of its illiquid off‐the‐run debt. The Treasury was successful in buying back large amounts of illiquid debt while suffering only a small market‐impact cost. The Treasury included the most‐illiquid bonds more frequently in the auctions, but tended to buy back the least‐illiquid of these bonds. Although the Treasury had the option to cherry pick from among the bonds offered, we find that the Treasury was actually penalized for being spread too thinly in the buybacks.     

Corporate Hedging Policy and Equity Mispricing

We show that firms’ use of derivatives is negatively associated with stock mispricing. This result is consistent with the notion that hedging improves the transparency and predictability of firms’ cash flows resulting in less misvaluation. Furthermore, we show that the negative relationship between mispricing and hedging is particularly strong when market value is below fundamental value, which is consistent with prior evidence that hedging has a positive impact on firm valuation. Finally, we provide evidence that a “spread‐out” hedging policy that entails the use of a variety of derivative contracts can be more effective in reducing mispricing.     

Treasury Bond Volatility and Uncertainty about Monetary Policy

We show that dispersion‐based uncertainty about the future course of monetary policy is the single most important determinant of Treasury bond volatility across all maturities. The link between Treasury bond volatility and uncertainty about macroeconomic variables is much stronger than for the more traditional time series measures of macroeconomic volatility and adds beyond the information contained in lagged bond market volatility. Uncertainty about monetary policy subsumes the uncertainty about future inflation (consumer price index and the deflator) and economic activity (unemployment, real and nominal gross domestic product and industrial production). In addition, causality clearly runs one way: from monetary policy uncertainty to Treasury bond volatility.     

Money Funds or Markets? Valuing Intermediary Services

Recent market developments, such as on-line trading of Treasury securities and the reduction of the minimum Treasury bill denomination to $1,000, facilitate creation of a viable alternative to U.S. Treasury money funds for investors. Comparison of a direct investment in Treasury bills to U.S. Treasury money funds shows that money fund intermediary services such as check writing, telephone exchange privileges, payroll and automatic transfers, retirement plans, and minimum initial and subsequent purchases are worth an estimated 43 basis points per year, and investors pay an additional 11 basis points for active portfolio management. An analysis of fund net cash flows shows evidence consistent with arbitrage activity between money funds and the direct investment in Treasury bills, especially for investors with few ties to the money fund manager.     

The informational content of the embedded deflation option in TIPS

We estimate the value of the embedded option in U.S. Treasury Inflation-Protected Securities (TIPS). The embedded option value exhibits time variation that is correlated with periods of deflationary expectations. We construct embedded option explanatory variables that are statistically and economically significant for explaining future inflation, even in the presence of traditional inflation variables such as lagged inflation, the gold return, the crude oil return, the VIX return, liquidity, surveys, and the yield spread between nominal Treasuries and TIPS. After conducting robustness tests, we conclude that the TIPS embedded option contains useful information for future inflation.     

Optimal portfolio choice in real terms: Measuring the benefits of TIPS

In this paper we solve an optimal portfolio choice problem to measure the benefits of Treasury Inflation Indexed Securities (TIPS) to investors concerned with maximizing real wealth. We show how the introduction of a real riskless asset completes the investor asset space, by contrasting optimal portfolio allocations with and without such assets. We use historical data to quantify gains from availability of TIPS in the presence of other asset classes such as equities, commodities, and real estate. We draw a distinction between buy-and-hold long-term investors for whom TIPS fully displace nominal risk-free assets and short-term investors for whom TIPS improve the investment opportunity set of real returns. Finally, we show how gains from TIPS are tempered by the availability of alternative assets that covary with inflation, such as gold and real estate.     

Are TIPS the “real” deal?: A conditional assessment of their role in a nominal portfolio

This paper documents predictable time-variation in the real return beta of US Treasury Inflation Protected Securities (TIPS) and in the Sharpe ratios of both indexed and conventional bonds. The conditional mean and volatility of both bonds and their conditional correlation first are estimated from predetermined variables. These estimates then are used to compute conditional real return betas and Sharpe ratios. The time-variation in real return betas and the correlation between TIPS and nominal bonds coincides with major developments in the fixed-income market. One implication of this predictability is that portfolio managers can assess more efficiently the risk of investing in TIPS versus conventional bonds. Conditional Sharpe ratios indicate that over the sample period, TIPS had superior volatility-adjusted returns relative to nominal bonds. This finding is striking in view of the absence of a major inflation scare during the sample period from February 1997 through August 2001, but is loosely consistent with the possibility that TIPS elevated rather than reduced Treasury borrowing costs. On the other hand, mean–variance spanning tests indicate that TIPS did not enhance the mean–variance efficiency of diversified portfolios.     

Where are the sources of stock market mispricing and excess volatility?

Using a simple dividend model, we illustrate and synthesize the sources of stock market mispricing and excess volatility based upon two hypotheses—inflation illusion and heterogeneous beliefs. Our theoretical framework posits that equity mispricing arises when investors have subjective expectations about discount rates or dividend growth rates. We then analyze the sources of equity mispricing and market excess volatility under a VAR framework. Empirically, we find that both inflation illusion and heterogeneous beliefs explain equity mispricing. However, heterogeneous beliefs play a more important role in explaining stock mispricing in the long run. We also find that heterogeneous beliefs cause excess volatility, but inflation illusion does not. Therefore, dispersion in investors’ beliefs is a better explanation of stock market mispricing than the investors’ inability to properly discount future cash flows.

An Empirical Analysis of Stock and Bond Market Liquidity

This article explores cross-market liquidity dynamics by estimatinga vector autoregressive model for liquidity (bid-ask spreadand depth, returns, volatility, and order flow in the stockand Treasury bond markets). Innovations to stock and bond marketliquidity and volatility are significantly correlated, implyingthat common factors drive liquidity and volatility in thesemarkets. Volatility shocks are informative in predicting shiftsin liquidity. During crisis periods, monetary expansions areassociated with increased liquidity. Moreover, money flows togovernment bond funds forecast bond market liquidity. The resultsestablish a link between "macro" liquidity, or money flows,and "micro" or transactions liquidity.
