The domestic term structure and international interest rate linkages: A cointegration analysis

The Domestic Term Structure and International Interest Rate Linkages. A Cointegration Analysis. -This paper analyzes cointegration relations between domestic interest rates with different maturities and between the US and German interest rates of the same maturity by means of the Johansen procedure and single-equation error correction models. It analyzes also the implied common stochastic trends. The author concludes that in the long run, interest spreads within both countries strongly dominate and linkages between the interest rates of both countries are only important in the short run.     

International Convergence of Capital Market Interest Rates

This article investigates the extent of capital market interest rate convergence among six EU countries on the one hand, and a group of four countries with floating exchange rates - US, Germany, Japan, and Switzerland - on the other. We conclude that interest rate changes within the EU have been and still are converging gradually since 1980. Within the group of free-float currencies, the increase in convergence occurred abruptly around 1980, after which the extent of convergence remained roughly constant. Moreover, the presumed higher influence of US long-term interest rates on the level of German interest rates could not be detected.     

A Sequential Test for Structural Breaks in the Causal Linkages Between the G7 Short-Term Interest Rates

This paper investigates changes in the causal structure linking the G-7 short-term rates by using a sequential test for the constancy of the adjustment coefficients in error correction equations. This technique allows us to detect permanent structural breaks in the causal linkages. In this instance, the hypotheses of interest are the US world-wide leadership, the disengagement of UK monetary policy from those pursued in the Eurozone after the collapse of the ERM, and the German leadership hypothesis (GLH) within the European Union (EU). While we do not find any examples of reversal of causality, the evidence points to a break in the causal linkages between the UK and the German rates after the third/fourth quarter of 1992. The empirical results are also consistent with a US world-wide leadership and a weak German leadership within the Eurozone.     

Asian Currency Crisis and the Generalized PPP: Evidence from the Far East

The present paper investigates the effects of the Asian currency crisis of 1997–1998 on the generalized PPP between several real exchange rates of the Far East countries. Monthly log of real exchange rates of the currencies of Thailand, Malaysia, Indonesia, the Philippines and South Korea vis-à-vis the US dollar and the Japanese yen during 1990–2004 are applied in the investigation. Further tests are conducted between exchange rates vis-à-vis the Thai baht. Tests are conducted for periods before and after the crisis. Results from the Johansen method of multivariate cointegration show a substantial change in the relationship between these real exchange rates before and after the Asian currency crisis. This result is found using rates based on three currencies: US dollar, yen and baht.     

Forecasting the Euro exchange rate using vector error correction models

Forecasting the Euro Exchange Rate Using Vector Error Correction Models. — This paper presents an exchange rate model for the Euro exchange rates of four major currencies, namely the US dollar, the British pound, the Japanese yen and the Swiss franc. The model is based on the monetary approach of exchange rate theory which uses fundamental macroeconomic variables to explain the exchange rate. A crucial point when using such a model is its proper estimation through cointegration analysis. The euro exchange rate model is therefore estimated in the form of a Vector Autoregressive (VAR) model with cointegrating vectors (VECM). We find that when cointegration analysis is undertaken properly, the naive random walk prediction can be out-performed for the US dollar, the British pound and the Japanese yen, but not for the Swiss franc.     

Wage-Setting and Inflation Targets in EMU

Although the operation of national coordinated wage-bargainingsystems in EMU has produced low inflation rates, EMU-wide inflationhas been above the ECB target rate for the last 3 years. Bycontrast, under the ERM, inflation rates declined steadily after1992 to below 2 per cent in both the last 2 years of the regime.It is argued that this was the consequence of two low-inflationincentives under ERM: (i) the Maastricht inflation conditionfor EMU entry; and (ii) the combination of the Bundesbank threatto raise interest rates if German wage and price inflation roseabove acceptable limits, linked to the need for other ERM membersto follow low German inflation to stay within the exchange-ratebands. These incentives no longer operate under EMU, where individualeconomies do not have an incentive to contribute to low EMU-wideinflation. We suggest that inflation coordination between thelarge EMU member states might contribute to a solution whilepermitting the continuation of real exchange-rate adjustmentsof smaller economies.     

Purchasing Power Parity Between the UK and Germany: The Euro Era

We use the Johansen cointegration approach to assess the empirical validity of the purchasing power parity (PPP) between the UK and Germany since the introduction of the euro. We conduct the empirical analysis in the context of the global financial crisis that began in 2007 and find that it directly affects the cointegration space. We fail to validate the Johansen and Juselius (1992) original hypothesis that nonstationarity of PPP associates with the nonstationarity of interest rate differentials to produce a stationary relation. On the other hand, we do not reject PPP. We find that PPP cointegrates with inflation differentials. We also find, contrary to conventional wisdom, that (i) equilibrium adjustment occurs between the German and UK inflation rates, while weak exogeneity exists for the German and UK interest rates and the PPP condition, and (ii) three common trends associated with the German interest rate the UK interest rate, and the PPP condition “push” the system with the German interest rate and the PPP condition playing dominant roles in affecting inflation in both Germany and the UK. These results cast serious doubt on the presumed independence of the UK monetary policy.     

Additional evidence on monetary base and interest rate linkages in the EMS

Conclusion This note has examined interest rate and monetary base linkages within the EMS. Cointegration tests suggest the existence of a long-run equilibrium relationship between German and other EMS interest rates and German and other EMS country monetary bases in a number of cases. Bivariate VAR analysis suggested that Granger causality with respect to EMS interest rate linkages stemmed either from German to European markets or was bi-directional and that the monetary base linkages were overwhelmingly bi-directional. When allowance is made for the influence of US monetary policy developments, the pattern of Granger causality within the EMS is predominantly bi-directional. These findings may be attributable to integrated financial markets and the discipline of a formal exchange rate mechanism. Thus, our results fail to support the hypothesis that German monetary policy plays a dominant and independent role within the EMS. Rather, they suggest that monetary policies in the EMS mainly respond to each other and, to a very limited extent, to developments in US monetary policy.     

The ASEAN dollar standard in the post-crisis era: A reconsideration

This paper examines the role of global currencies in ASEAN exchange rate regimes. The investigation considers the post-crisis era from January 1, 1999 through December 31, 2007 and focuses on the five original members of ASEAN (Indonesia, Malaysia, Philippines, Singapore, Thailand) plus Vietnam. Unlike most papers that use classical regression analysis of logarithmic data in first differences to detect the influence of various foreign currencies on particular Asian currencies, this paper considers modern time series analysis more seriously. In particular, this paper finds evidence of cointegration among individual ASEAN currencies and some of the global currencies, indicating a long-run relationship. Examination of the cointegrating vectors yields four main findings. First, there is a notable absence of a clear US dollar standard. Second, the yen is downright unimportant, suggesting that ASEAN currencies are quite far from a yen standard. Third, ASEAN currencies are also quite far from a euro standard. Fourth, and most surprisingly, the UK pound is very important. These results are at odds with the traditional (short-run) regressions which suggest that ASEAN is on a dollar standard, although it is not a perfect dollar standard because coefficients are not at unity and various other currencies are significant in different equations. Hence, the overall conclusion from this research is that there is a wide variety of influences on ASEAN exchange rates in both the long run and the short run. This suggests that ASEAN, as a group, is not pursuing – and is in fact not ready for – a global-currency standard.     

LONG-RUN M3 DEMAND IN SOUTH AFRICA: A COINTEGRATED VAR MODEL

This paper presents a system cointegration analysis of a long‐run demand for money (measured in terms of M3) in South Africa. In particular, the paper estimates a cointegrated vector autoregression model, consisting of real money, income and the opportunity cost of holding money. Using a variety of theory consistent identification schemes, the money demand function is identified along with other two cointegrating relations, namely, an IS‐type relationship and a relationship relating inflation to the spread between long‐ and short‐term interest rates. The model shows that of the variables used, only income and real money are error‐correcting to the money demand relation. The money demand relation is found to be relatively stable over the sample period, when short‐run fluctuations are corrected for. The model further shows that the long‐run link between money and inflation is rather weak.     

International Interest-Rate Transmission and the “German Dominance Hypothesis” Within EMS

This article investigates whether the German Dominance Hypothesis is valid within the context of nominal short-term interest rates. The approach taken to address this hypothesis is based on the notion that German interest rates should convey valuable information to other countries' rates or that there exist significant multidirectional volatility spillovers from the Bundesbank to other nations' central banks. These transfers can be analyzed within a multivariate framework of an Exponential GARCH model capable of capturing the potential asymmetries of the volatility spillover mechanism. The results, basically, do not support the idea of a German predominance within the system, in a strict sense, since Germany's rates are also affected, for the most part, by actions from its partners.     

Currency Misalignments in the BRIICS Countries: Fixed Vs. Floating Exchange Rates

In the present paper we attempt to investigate whether the real effective exchange rates of the BRIICS countries, namely Brazil, Russia, India, Indonesia, China and South Africa, converge or not to their equilibrium levels. Our analysis is based on the use of an external balance model as well as the implementation of recent panel cointegration techniques. Our evidence indicates the existence of a valid long-run relationship between the real effective exchange rate, the net foreign assets, the GDP differential and the real interest rate differential for each of the six countries of our sample. Furthermore, our empirical results imply that after the adoption of a free floating exchange rate regime by Brazil, Russia, India, Indonesia and South Africa and the liberalisation of the Chinese exchange rate policy that took place during the last decade, currency misalignments have been gradually reduced, leading the real effective exchange rates of the respective currencies very close to their equilibrium levels.     

INFLATION TARGETING AND THE FISHER EFFECT IN SOUTH AFRICA: AN EMPIRICAL INVESTIGATION

The paper analyses the relationship between expected inflation and nominal interest rates during a period of inflation targeting in South Africa, i.e. from 2000 to 2005. Specifically, it investigates the Fisher hypothesis that nominal interest rates move one‐to‐one with expected inflation, leaving the real interest rate unaffected. The analysis distinguishes between a short‐run Fisher effect and a long‐run Fisher effect. Using cointegration and error correction models (for monthly data for the period April 2000 to July 2005), it was found that the short‐run Fisher hypothesis did not hold during the relevant period under the inflation targeting monetary policy framework in South Africa. This is attributed to a combination of the South African Reserve Bank's (SARB) control over short‐term interest rates and the effects of the monetary transmission mechanism. The long‐run Fisher hypothesis could not be confirmed in its strictest form: while changes in inflation expectations move in the same direction as the nominal long‐term interest rate. This suggests that monetary policy has an influence on the real long‐term interest rate, which has positive implications for general economic activity, thus confirming the credibility of the inflation targeting framework.     

Purchasing Power Parity before and after the Adoption of the Euro

This paper examines the purchasing power parity (PPP) hypothesis for the post–Bretton Woods era including the period after the introduction of the euro. The study applies a new nonlinear unit root test to the bilateral real exchange rates (RERs) of both European and other industrial countries with the French franc and German mark (and the euro after 1998), as well as the US dollar as numeraire currencies. The results of the study provide stronger support for PPP than any earlier studies of bilateral PPP for industrial countries and suggest that (1) PPP tends to hold well within the European Union (EU) even before the adoption of the euro, (2) the evidence for PPP becomes more significant for both EU and non-EU countries when the sample period is extended to the euro era, and (3) convergence toward PPP between the EU countries, especially between the euro-area countries, tends to be nonlinear, while it is likely to be linear for the non-EU industrial countries.

Measuring currency pressures: The cases of the Japanese yen,the Chinese yuan,and the UK pound

We investigate bilateral currency pressures against the US dollar for three currencies: the Japanese yen, the Chinese yuan, and the UK pound during the period 2000:Q1 to 2009:Q4. We employ a model-based methodology to measure exchange market pressure over the period. Conversion factors required to estimate the pressure on these currencies are computed using a time-varying coefficient regression. We then use our measures of currency pressures to assess deviations of exchange rates from their market-equilibrium levels. For the yen, our measure of currency pressure suggests undervaluation during the initial part of our estimation period, a period during which the Bank of Japan sold yen in the foreign exchange market. We find persistent undervaluation of the yuan throughout the estimation period, with the undervaluation peaking at about 20% in 2004 and 2007. For the pound, the results indicate low pressure – suggesting a mainly free-floating currency – throughout the sample period. These results appear consistent with the policies pursued by the central banks of the currencies in question.     

Evidence of long-run purchasing power parity: analysis of real asian exchange rates in terms of the Japanese yen

In this paper we find strong new evidence in favour of the long-run purchasing power parity (PPP) hypothesis in the bilateral real exchange rates between the Japanese yen and the currencies of the most important southeast Asian economies only when the presence of several possible structural breaks of the series is taken into account. Such evidence for PPP is weaker for these southeast Asian exchange rates with the US dollar, the German mark and the Australian dollar.     

Excess returns in the EMS: Do “weak” currencies still exist after the widening of the fluctuation bands?

Excess Returns in the EMS: Do “Weak” Currencies Still Exist after the Widening of the Fluctuation Bands? — The authors analyze the issue of how the different institutional arrangements within the ERM have affected the behaviour of excess returns on DM-denominated assets and contribute to the debate on the future of the EMS. Their approach consists in estimating simple forecasting models for interest differentials, and testing for the presence of significant (negative) mean prediction errors. The comparison between predicted and actual outcome indicates that the new system might be characterized by the virtual disappearance of “weak” currencies, as the widening of the bands has removed the expectations of realignments which resulted in high interest differentials.     

The stability of German money demand: Tests of the cointegration relation

The Stability of German Money Demand: Tests of the Cointegration Relation. — In this study, two money demand functions are specified in single equation error correction as well as triangular error correction form involving real M1 (M3), real GNP, a short-and a long-term interest rate. Using various tests, it is shown that there may be a cointegration relation even after the German Monetary Union (GMU) was established in 1990. But the long-run coefficients of GNP and the interest rate probably have a structural break in 1973, when the Bundesbank changed its monetary regime, and in 1990, when the GMU was formed. The tests support weak exogeneity of real GNP and the interest rate.     

Real Exchange Rate Dynamics in the Asian Economies: Can Regime Shifts Explain Purchasing Power Parity Puzzles?

Abstract

We show that the strong version of the purchasing power parity (PPP) hypothesis holds in most of the US dollar real exchange rates using cointegration method that accounts for breaks in the models. The break dates in seven of the Asian currencies coincide with the two rounds of currency depreciation recorded during the 1997–1998 financial crises. We obtain a mean half-life estimate of about 10 months for PPP to converge to its long-run equilibrium level. Our confidence intervals based on persistence profile approach for the half-lives is much narrower than previous evidence might indicate. Taken together, these results show that mean reversion is stronger than commonly thought.
