A test of the expectations hypothesis of the term structure of interest rates for Sri Lanka

This paper tests the expectations hypothesis of the term structure of interest rates for Sri Lanka. The data support the hypothesis that forward and spot rates are cointegrated suggesting a stochastic trend in the structure of interest rates. However, the hypothesis that forward rates are unbiased predictors of future spot rates is rejected.     

Inflation and real short-term interest rates - A Kalman filter analysis of the term structure

This paper applies the Kalman filter technique to look at the relationship among real interest rates, inflation, and the term structure of interest rate under the expectations hypothesis. Using quarterly data from 1960:1 to 1991:1 for inflation, three month nominal short term interest rates and long term yields with maturities from one to five years, this paper finds that the expectations hypothesis of the term structure holds up well for the data under the assumptions of a time-varying premium and a random-walk real interest rate. In other words, a reconciliation of the expectations hypothesis with the data is attained by assuming time-varying term premium and non-stationary real interest rate.     

An empirical note on Euro market interest rates,domestic interest rates and the expectations theory of the term structure

An empirical analysis of recent monthly data for 8 currencies indicates that the performance of the expectations theory to explain the short term maturity spectrum of Euro interest rates is rather good in most cases and that it is not related to the degree of integration of Euro and domestic markets.     

A RE‐EXAMINATION OF REAL INTEREST PARITY IN CEECs USING ‘OLD’ AND ‘NEW’ SECOND‐GENERATION PANEL UNIT ROOT TESTS

This study applies ‘old’ and ‘new’ second‐generation panel unit root tests to check the validity of the long‐run real interest rate parity (RIP) hypothesis for ten Central and Eastern European Countries (CEECs) with respect to the Euro area and an average of the CEECs’ real interest rates. When the ‘new’ panel unit root tests are carried out relative to the Euro area rate as reference, we confirm the results of previous studies that support the RIP hypothesis, and the results of the ‘old’ tests used as a benchmark. Nevertheless, when the ‘new’ tests are performed using the average of the CEECs’ rate as reference, our results are mitigated, revealing that the hypothesis of CEECs’ interest rates convergence cannot be taken for granted. From a robustness analysis perspective, our findings indicate that the RIP hypothesis for CEECs should be considered with caution, because the RIP hypothesis is sensitive to the retained reference rate for computing the real interest rate differential, and also to the retained countries in the sample.     

How is the Debt Managed? Learning from Fiscal Stabilizations

This paper examines public debt management during episodes of fiscal stabilization when long–term interest rates are generally higher than governments' expectations of future rates. We find that governments increase the share of fixed–rate long–term debt denominated in the domestic currency, the higher is the conditional volatility of short–term interest rates, the lower are long–term interest rates, and the stronger is the fall in long–term rates that follows the announcement of the stabilization program. This evidence suggests that governments tend to prefer long to short maturity debt because they are concerned about refinancing risk. However, when long–term rates are high relative to their expectations, they issue short maturity debt to minimize borrowing costs.

A Theory of Exchange Rates and the Term Structure of Interest Rates

This paper defines the concepts of indirect and direct risk premium effects and analyzes their properties in an exchange rate model. In the model, these effects are endogenously determined in a rational expectations equilibrium. For the effect of an interest rate shock, they have the opposite signs and the indirect risk premium effect can dominate the direct risk premium effect under reasonable parameters. This means that domestic short‐term bonds and foreign bonds are complements in the model even though domestic long‐term bonds and foreign bonds are substitutes. This model, focusing on the indirect risk premium effect and on the term structure of interest rates, can be combined with a small sample bias approach to explain stylized facts about the forward premium anomaly, which is found for short‐term interest rates, but not for long‐term interest rates.     

Risk premia in forward foreign exchange rates: a comparison of signal extraction and regression methods

We investigate possible presence of time-varying risk premia in forward pound, yen, and Euro monthly exchange rates versus the US dollar over the last two decades. We study this issue using regression techniques and separately using a signal plus noise model. Our models account for time-varying volatility and non-normality in the observed series. Our regression model rejects the hypothesis that the forward rate is an unbiased predictor of future spot exchange rate, indicating the existence of time-varying risk premium under rational expectations. Our signal plus noise model reveals a time-varying risk premium component in yen and Euro. The same model provides evidence for the presence of risk premium in pound over a shorter sample period, though not over the entire sample. We conclude that risk premia exist, although we may fail to detect these for some currencies over specific time periods.     

Forward rates and the expectations theory of the term structure: Tests for the Federal Republic of Germany

The expectations theory of the term structure was tested using data from West German capital and money markets for the period 1975:01–1986:12. If forward rates implicit in the term structure are market expectations of future spot rates, and if term premia are not time-dependent, then forward rates should follow a martingale sequence. This hypothesis was tested with the aid of standard time series techniques (autocorrelation functions, Box-Pierce, unit-roots,F-tests and co-integration). The expectations theory was for the most part rejected, although the martingale property, or equivalently, weak form efficiency, held for the latter part of the test period. The rejection of the simple expectations theory is consistent with the hypothesis of time-varying term premia. The author thanks an anonymous referee and especially Prof. Dr. J. Wolters (Free University of Berlin) for helpful comments and criticism.     

Risk and Policy Shocks on the US Term Structure

We document two stylized facts of US short‐term and long‐term interest rate data seemingly incompatible with the expectations hypothesis: low contemporaneous cross‐correlation and relatively slow adjustment to long‐run relationships. We explain these features in a small structural model with three types of randomness: While a persistent monetary policy shock implies immediate identical reactions through the term structure, both a transitory policy shock and an autocorrelated risk premium allow for sustained deviations. Indeed, we find important impacts and persistence of risk premia and considerable contribution of transitory policy shocks to short rates. Results of standard expectations hypothesis tests can be rationalized.     

Term structure and forward guidance as instruments of monetary policy

This paper studies a simple monetary model with a Ricardian fiscal policy in which equilibria are indeterminate if monetary policy consists solely of a rule for fixing the short-term interest rate. We introduce explicitly into the model the agents’ expectations of inflation which create the indeterminacy and show that there are two types of policies—a term structure rule or a forward guidance rule for the short rate—which lead to determinacy. The first consists in fixing the interest rates on a family of bonds of different maturities as function of realized inflation; the second consists in fixing the short-term interest rate and the expected values of the short-term interest rate for a sequence of periods into the future as a function of realized inflation. If the monetary authority chooses an inflation process that satisfies conditions derived in the paper and applies one of these rules, it anchors agents’ expectations to this process, in the sense that it is the unique inflation process compatible with equilibrium when the interest rates or expected future values of the short rate are those specified by the term structure or forward guidance rule.     

Nonstationarity,cointegration and structural breaks in the Australian term structure of interest rates

This article examines the unit-root property of the Australian short- and long-term interest rates using unit-root tests that accommodate a single or two breaks under the null and/or alternative hypothesis. Two breaks in interest rates are found to coincide with the 1982/83 and 1990/91 recessions or the 1993 inflation targeting period. We further investigate the implications of these structural breaks on the cointegrating relationship implied by the single, linear expectations hypothesis of the term structure of interest rates. While there is evidence that the data are consistent with the expectations hypothesis at the shorter end of the term structure, breaks in interest rates generate a shift in the cointegrating relationship, thus altering the information content of the term structure. Failing to account for a regime shift in the cointegration regression, the data erroneously supports the expectations hypothesis at the longer end of the term structure. These results have profound implications for policy makers who may inadequately exploit the information content of the term structure to predict future changes in inflation.     

Yield Curve and Financial Uncertainty: Evidence Based on US Data

How do short‐ and long‐term interest rates respond to a jump in financial uncertainty? We address this question by conducting a local projections analysis with US monthly data, period: 1962–2018. The state‐of‐the‐art financial uncertainty measure proposed by Ludvigson, Ma and Ng (2019) is found to predict movements in interest rates at different maturities. In particular, an increase in financial uncertainty is found to trigger a negative and significant response of both short‐ and long‐term interest rates. The response of the short end of the yield curve (i.e., of short‐term interest rates) is found to be stronger than that of the long end (i.e., of long‐term ones). In other words, a financial uncertainty shock causes a temporary steepening of the yield curve. This result is consistent, among other interpretations, with medium‐term expectations of a recovery in real activity after a financial uncertainty shock.     

Fractional cointegration and the term structure

According to the expectations theory of the term structure of interest rates, the yield spread between long-term and short-term interest rates is an optimal predictor of future changes in short rates over the long-run. Results concerning the empirical validity of this hypothesis are not unanimous. These contradictions may be due to the fact that the traditional concept of cointegration is too restrictive. We refer here to the concept of fractional cointegration introduced by Granger (1986). We study the expectations theory by testing for the existence of a (fractional) cointegration relationship between short-term and long-term interest rates. There is evidence of fractional cointegration between interest rates for the G7 countries, with the exception of Germany.First version received: July 2002 / Final version received: July 2003We thank two anonymous referees for very helpful and detailed comments.     

The Bundesbank's Inflation Policy and Asymmetric Behavior of the German Term Structure

The paper analyzes the influence of the Bundesbank's inflation targeting policy on the behavior of the spread between long‐term and short‐term German interest rates. The term spread is considered to be a key indicator of future inflation and economic activity. The application of a momentum threshold autoregressive cointegration model enables the authors to study the adjustment process of the spread toward equilibrium in greater detail than heretofore possible, and permits relaxation of the linear and symmetric adjustment assumption underlying conventional cointegration and error correction investigations on the expectations hypothesis. The empirical findings are consistent with the hypothesized asymmetric adjustment behavior of the spread and can be explained by the Bundesbank's inflation targeting policy during the period from 1975 to 1998.     

The conditional influence of term spread and pattern changes on future equity returns

We extend previous research examining the relation between interest rates and equity returns using a multivariate analysis of covariance model with a dynamic yield curve and conditioned term spread. We find yield pattern changes predict economic equity returns; that the long end-of-yield curve is a strong determinant factor; and, in contrast to previous research, we find no relation between a decrease in the short rate and equity returns. However, the conditional term spread captures a significant positive return indicating that the degree of decline in the short rate relative to the long rate is of more importance than the term spread alone.     

Arbitrage-free valuation of interest rate securities under forward curves with stochastic speed and acceleration

Arbitrage-free models for valuing interest rate securities posit that stochastic changes in spot or forward interest rates (forward rate “speed”) follow a diffusion process. This paper extends the Heath, Jarrow and Morton [Bond pricing and the term structure of interest rates: a new methodology for contingent claims valuations, Econometrica 60 (1992) 77-105], HJM framework by allowing diffusive shocks to both the “speed” and “acceleration” of forward rates. The arbitrage-free restriction on forward rates is identified and involves volatilities of the speed and acceleration dynamics and their correlation. Although the extended forward rates remain in the diffusive framework and evolve continuously, they may exhibit large changes over short intervals (as with jumps) due to stochastic acceleration. Comparisons of bond prices show that the proposed model generates more complex and intricate shapes for the restricted forward curve with the same number of stochastic factors and volatility.     

TRUMP,TWITTER, AND TREASURIES

After appointing Federal Reserve Chairman Powell, President Trump put pressure on the Fed to cut interest rates. We show that, on average, a statement from Trump on the Fed led to lower long‐term interest rates, consistent with expectations of lower expected future short rates. However, the impact of Trump's statements declined over time. (JEL E52, E43, E32)     

Exchange Rates and Long‐Term Bonds*

There is tentative evidence to suggest that the well‐documented empirical failure of uncovered interest parity (UIP) is confined to short‐term interest rates. However, tests of UIP for long‐term bonds are thwarted by various data problems. These data problems can be avoided by focusing on short investments in long‐term bonds. This paper concerns the relationship between changes in the US dollar–Deutsche Mark exchange rate and returns to short investments in US and German long‐term government bonds. The hypothesis that expected returns to investments in bonds denominated in the two currencies are equal is not rejected, and the estimated slope coefficients are positive. For corresponding short‐term interest rates, the typical finding of negative and large Fama coefficients is confirmed. We conclude that it is the maturity of the asset, rather than the investment horizon, that matters for the results.     

Overshooting in the foreign exchange market: Evidence from the 1970s

This paper analyzes the reaction of spot and forward exchange rates to unanticipated weekly money supply changes. The empirical results tend to support the (overshooting) hypothesis that equilibrium exchange-rate changes that occur in the short run in response to an unanticipated event exceed the equilibrium exchange-rate change in the long rung.
