Behavioural equilibrium exchange rate and total misalignment: evidence from the euro exchange rate

In the present paper we attempt to investigate whether the nominal exchange rate of the euro against the currencies of the four major trading partners of the eurozone, namely China, Japan, the UK and the USA, converges or not to its equilibrium level. Applying recent unit root and system cointegration techniques in the presence of structural shifts in the data, our results indicate that there exist an equilibrium relationship between each of the euro/yuan, euro/yen, euro/UK pound and euro/US dollar nominal exchange rates and the fundamentals defined by the monetary model. Following these results, our modified Behavioural Equilibrium Exchange Rate model suggests that at the end of the estimated period, the euro/Chinese yuan and the euro/UK pound nominal exchange rates follow an equilibrium process. Our empirical results also imply that the single European currency is considered as overvalued against the US dollar, while it is considered as undervalued against the Japanese currency.     

Bi‐currency versus Single‐currency Targeting: Lessons from the Russian Experience

This paper examines how the 2005 shift in Russian exchange rate policy from US dollar (USD) single‐currency to USD–EUR (euro) bi‐currency targeting has impacted domestic interest rates. The finding show that this policy shift has disconnected Russian interest rates from US dollar‐denominated interest rates, while instead linking them to a synthetic interest rate composed of USD and EUR rates at the same proportion as that of these two currencies in the currency basket against which the ruble's exchange rate is set. The Russian experience shows that while the adoption of bi‐currency targeting may help ensure that domestic interest rates are less dependent on the monetary cycle of a single country, these rates are instead likely to reflect financial developments in all countries whose currencies are included in the currency basket. This insight is likely to be relevant for other countries that pursue basket‐targeting policies.     

Nonlinear adjustment in the real dollar–euro exchange rate: The role of the productivity differential as a fundamental

In this paper we analyze the influence of productivity differentials in the dynamics of the real dollar–euro exchange rate. Using nonlinear procedures for the estimation and testing of ESTAR models during the period 1970–2009 we find that the dollar–euro real exchange rate shows nonlinear mean reversion towards the fundamentals represented by the productivity differential. In addition, we provide evidence about the ability of this variable to capture the overvaluation and undervaluation of the dollar against the euro.     

Do China and oil exporters influence major currency configurations?

This paper analyses the impact of the shift away from a US dollar focus of systemically important emerging market economies (EMEs) on configurations between the US dollar, the euro and the yen. Given the difficulty that fixed or managed US dollar exchange rate regimes remain pervasive and reserve compositions mostly kept secret, the identification strategy of the paper is to analyse the market impact on major currency pairs of official statements made by EME policy-makers about their exchange rate regime and reserve composition. Developing a novel database for 18 EMEs, we find that such statements not only have a statistically but also an economically significant impact on the euro, and to a lesser extent the yen against the US dollar. The findings suggest that communication hinting at a weakening of EMEs’ US dollar focus contributed substantially to the appreciation of the euro against the US dollar in recent years. Interestingly, EME policy-makers appear to have become more cautious in their communication more recently. Overall, the results underscore the growing systemic importance of EMEs for global exchange rate configurations.     

What Do We Know About Long–run Equilibrium Real Exchange Rates? PPPs vs Macroeconomic Approaches

Despite the fact that the presence of non tradable goods is one of the most frequently advanced reasons for the failure of PPP, the empirical analysis conducted in this paper shows that it explains only a very small portion of the long run behaviour of real exchange rates (RERs) in developed countries: in most cases, there appears to be a very strong long run relationship between RERs calculated on price indexes for tradables and non tradables. As a consequence, deviations from PPP usually appear to be as large for both kinds of goods. To a certain extent, this stylised fact is also verified in the case of the yen/dollar RER, yet formerly known as a typical illustration of the so–called Balassa–Samuelson effect. In this context, so–called macroeconomic approaches of ERERs may be viewed as an alternative to all versions of PPP. We develop a model which combines the contributions of the most fruitful dynamic approaches, namely the NATREX and the BEER. An estimate of this model shows that the main long run determinants of the dollar/euro RER are the rate of consumption and the level of technical progress of the euro area relative to the US.     

NEW ESTIMATION OF CHINA'S EXCHANGE RATE REGIME

Abstract. The present paper updates the question: what precisely is the exchange rate regime that China has put into place since 2005, when it announced a move away from the US dollar peg? Is it a basket anchor with the possibility of cumulatable daily appreciations, as was announced at the time? We apply to this question a new approach of estimating countries’ de facto exchange rate regimes, a synthesis of two techniques. One is a technique that has been used in the past to estimate implicit de facto currency weights when the hypothesis is a basket peg with little flexibility. The second is a technique used to estimate the de facto degree of exchange rate flexibility when the hypothesis is an anchor to the US dollar or some other single major currency. Because the RMB and many other currencies today purportedly follow variants of band‐basket‐crawl, it is important to have available a technique that can cover both dimensions, inferring weights and inferring flexibility. The synthesis adds a variable representing ‘exchange market pressure’ to the currency basket equation, whereby the degree of flexibility is estimated at the same time as the currency weights. This approach reveals that by mid‐2007, the RMB basket had switched a substantial part of the US dollar's weight onto the euro. The implication is that the appreciation of the RMB against the US dollar during this period was due to the appreciation of the euro against the dollar, not to any upward trend in the RMB relative to its basket.     

Reverse Causality in Global and Intra‐European Imbalances

The paper discusses global current account imbalances in the context of an asymmetric world monetary system. It identifies the USA and Germany as center countries with rising/high current account deficits (USA) and surpluses (Germany). These are matched by current account surpluses of countries stabilizing their exchange rates against the dollar (dollar periphery) and current account deficits of countries stabilizing their exchange rates against the euro or members of the euro area (euro periphery). The paper finds that changes of world current account positions are closely linked to the monetary policy decision patterns both in the centers and peripheries. Whereas in the centers current account positions are affected by monetary policies, in the peripheries exchange rate stabilization cum sterilization matters. In specific, monetary expansion in the USA as well as exchange rate stabilization and sterilization policies in the dollar periphery are found to have contributed to global imbalances.     

Volatility and Spillover Effects of Yen Interventions

We consider the effects of interventions by the Bank of Japan's (BoJ) on the intraday volatility of the US dollar/Japanese yen (USD/JPY) exchange rates and their spillovers to volatility of the euro/JPY exchange rates. We use 15‐minute data during the period 2000–2004 and employ multivariate generalized autoregressive conditional heteroskedasticity (GARCH) modeling and quartile plots of intraday volatility to analyze the intraday effects of the BoJ interventions on exchange rate volatility. The results indicate that the BoJ interventions decrease daily volatility of the USD/JPY exchange rate but increase the volatility of the euro/JPY series. On intervention days, the intraday volatility has different patterns to those on non‐intervention days.     

China's Exchange Rate Policy and Its Trade Balance with the US

This paper investigates the claim that China's exchange rate policy causes the US trade deficit with China to grow. Although there is no evidence that changes in the exchange rate cause the trade deficit to rise in the short run, a statistically significant long‐run relationship between the RMB/dollar exchange rate and the US trade deficit with China is detected. As the value of the dollar declines (or RMB appreciates), ceteris paribus, so does the trade deficit. Hence, there is a need for China to adjust its exchange rate policy to help reduce the ever mounting US trade deficit.     

Market efficiency broadcasted live: ECB code words and euro exchange rates

This paper examines the impact of the European Central Bank (ECB) monetary policy on euro exchange rate returns using an event study with intraday data for five currencies (the euro exchange rate versus the US dollar, the British pound, the Canadian dollar, the Swiss franc, and the Japanese yen). I construct two indicators of news about monetary policy stemming separately from policy decisions and the press conference. Estimation results show that the surprise component of communication has highly statistically significant effects on exchange rates, whereas the response of euro exchange rates to the unanticipated change in the policy rate is more muted. I also estimate the financial market impact on euro exchange rates of US, European and German macroeconomic news, and I show that the impact of the ECB press conference is economically important. The process of fully incorporating the ECB news shock takes about 1 h, and thus this result suggests that the whole press conference (both the Introductory Statement and the Q&A part) provides valuable information to market participants.     

Unconventional monetary policy and the dollar–euro exchange rate: first results from time-series analysis

This article examines the impact on the US dollar–euro (USD–EUR) exchange rate of the unconventional monetary policy conducted by the US Federal Reserve (Fed) and the European Central Bank (ECB). To that end, we make use of time-series analysis to obtain a reasonable long-run and short run representation of the data generation process and use dummy variables to study how announcements about monetary policy changes can affect the USD–EUR exchange rate. Our results indicate that the announcement and subsequent implementation of such measures by the ECB would have caused an appreciation of the dollar, while those by the Fed would have caused a depreciation of the dollar.     

Excess comovements between the euro/US dollar and pound sterling/US dollar exchange rates

ABSTRACT

The aim of this article is to discuss excess comovements of the euro/US dollar and pound sterling/US dollar exchange rates, i.e. we look for comovements of exchange rates which are stronger than implied by the fundamentals. The results of the empirical analysis provide evidence that excess comovements exist for the two exchange rates. A long-run analysis of correlations can verify that a link exists between the correlation dynamics of exchange rates, relative inflation rates, long-term interest rates, economic sentiments and money supply. We find that common movements of money supply, prices and economic sentiments each play a major role in comovements of the exchange rates. From the investigation of the two exchange rates, we conclude that macroeconomic fundamentals can account for the comovement but that common non-fundamental factors also have major significance for the exchange rates.     

Endogenous Growth in an Open Economy and the Real Exchange Rate

This paper is a step in the direction of a larger research project aimed at determining the long run equilibrium value of the euro/dollar real exchange rate. Given this value, one could then give a precise meaning to the notion of undervaluation or overvaluation of the euro, and calculate its misalignment. The problem however arises of how to assess the reliability of such misalignment calculations. In our opinion, we must have a benchmark (namely a period in which we exactly know from outside sources the misalignment itself), against which we can test the validity of the model underlying our calculations. This of course is not (yet) possible for the euro, so that all the calculations of the misalignment of the euro that have been made can only be compared with one another, without knowing which is the good one. Hence, before building a model to be applied to the euro/dollar, we tested our ideas incorporating them in a basic model to be applied to the lira/dollar in a period in which we do know the actual misalignment of the lira from outside sources.     

Uncovered Interest Parity at Long Horizons: Evidence on Emerging Economies*

This paper estimates uncovered interest parity (UIP) at long horizons using bilateral US dollar rates vis‐à‐vis mature economy and emerging market currencies. The paper finds support in favor of UIP for dollar rates vis‐à‐vis major mature economy currencies, but far less against emerging market currencies. There are also signs that political risk and the exchange risk premium help explain the empirical failure of UIP for these latter currencies. This suggests that whether UIP holds depends more on the currency than on the horizon.     

Non‐linearities,Business Cycles and Exchange Rates

This paper conjoins the disparate empirical literatures on exchange rate models and monetary policy models, with special reference to the importance of output, inflation gaps and exchange rate targets. It focuses in on the dollar/euro exchange rate, and the differential results arising from using alternative measures of the output gap for the US and for the Euro area. A comparison of ‘in‐sample’ prediction against alternative models of exchange rates is also conducted. In addition to predictive power, I also assess the various models' plausibility as economic explanations for exchange rate movements, based on the conformity of coefficient estimates with priors. Taylor rule fundamentals appear to do as well, or better, than other models at the 1‐year horizon.     

Carry trade and forward premium puzzle from the perspective of a safe‐haven currency

Swiss franc exchange rates exhibit safe‐haven characteristics, which suggest a close link between the forward premium puzzle and profitability of the carry trade. Our analysis of Swiss franc exchange rates shows that the two phenomena are distinct from each other, thus corroborating U.S. dollar evidence. Persistent exposures to two different global shocks drive the two phenomena in Swiss franc exchange rates. Moreover, we find significant links between expected average Swiss franc exchange rate changes and macroeconomic conditions during the period of the minimum Swiss franc exchange rate against the euro, but not during the rest of the sample period.     

The impact of foreign macroeconomic news on financial markets in the Czech Republic, Hungary, and Poland

In this paper, we investigate the effects of euro area and US macroeconomic news on financial markets in the Czech Republic, Hungary, and Poland (CEEC-3) from 1999 to 2006. Using a GARCH model, we examine the impact of news on daily returns of 3-month interest rates, stock market indices, exchange rates versus the euro, and the US dollar. First, both US and European macroeconomic news has a significant impact on CEEC-3 financial markets. Second, the process of European integration is accompanied by an increasing importance of euro area news relative to US news. Third, there are country-specific differences: for example, the Czech stock market is relatively more affected by foreign news since the Copenhagen Summit in December 2002. In general, our results support the hypothesis of a deepening euro area influence on the CEEC-3 over time and a corresponding reduction in the relative importance of US shocks.     

欧元问世后国际储备货币竞争格局与欧元危机

欧元问世以来,国际储备货币竞争格局由美元垄断已经演化成美元与欧元的双头竞争。研究显示,造成欧元危机的真正原因是全球欧元储备份额的持续上升,它严重削弱了美元的全球霸权和美国的国家利益,欧元危机不是由债务国违约引发,而是由美国的评级机构调降这些国家的主权债务评级引发。本文认为,只要现存的国际储备货币体系仍然得以维持,欧元危机就不会导致欧元崩溃和欧元终结。     

News and correlations of CEEC-3 financial markets

We employ DCC-MGARCH models to investigate conditional correlations between six CEEC-3 financial markets. In general, the highest correlations exist between Hungary and Poland in foreign exchange and stock markets. Short-term money markets are somewhat isolated from each other. We find that the associations of CEEC-3 exchange rates versus euro are weaker than those versus the US dollar. The persistence of the effect of shocks on the time-varying correlations is strongest for foreign exchange and stock markets, indicating a tendency toward contagion. In searching for the origins of financial market volatility in the CEEC-3, we uncover some evidence of Granger-causality on the foreign exchange markets. Finally, using a pool model, we investigate the impact of euro area, US, and CEEC-3 news on the correlations. Apart from ECB monetary policy news, we observe no broad effects of international news on correlations; instead, local news exerts an influence, which suggests a dominance of country- or market-specific circumstances.     

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.
