Collective Perception and Exchange Rates

The authors' research suggests that people search online for information on currency exchange rates and that this information-seeking process can be translated into data on people's interest for a given currency. The authors utilize Google Trends data to capture the level of interest in 3 currency pairs: the euro, the pound sterling, and the Canadian dollar against the U.S. dollar and conduct a multivariate data analysis in the context of vector-autoregressive models. The findings suggest that there is a small but significant impact on collective perception on exchange rates. The authors show that Google Trends data could be an important source of information for investors looking into exchange rate trends.     

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.     

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.     

Fractional Integration of Nominal Exchange Rates: Evidence from CEECs in the Light of EMU Enlargement

This paper uses fractional integration models to describe the long‐run dependence of nominal exchange rates in Central and Eastern European countries (CEECs). The analysis is validated using nonparametric, semiparametric and parametric techniques. From comparing the results across the three approaches, it was clear that mean reversion takes places only for the euro exchange rates in Bulgaria, Estonia, and Slovenia. Other exchange rates based on the euro also display mean reversion with the parametric methods. For the US dollar rates, the unit‐root null hypothesis cannot be rejected in any single country, indicating that shocks affecting the exchange rates against the US dollar are of a permanent nature, while those directed against the euro are less persistent, and tend sometimes to disappear in the long run. Policy implications are derived.     

West African Single Currency and Competitiveness

This paper compares different nominal anchors to promote internal and external competitiveness in the case of a fixed exchange rate regime for the future single regional currency of the Economic Community of the West African States (ECOWAS). We use counterfactual analyses and estimate a model of dependent economy for small commodity exporting countries. We consider four foreign anchor currencies: the US dollar, the euro, the yen and the yuan. Our simulations show little support for a dominant peg in the ECOWAS area if they pursue several goals: maximizing the export revenues, minimizing their variability, stabilizing them and minimizing the real exchange rate misalignments from the fundamental value.     

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.     

“New” monetary policy instruments and exchange rate volatility

Turkish economy has been suffering from rises in financial flows since the last two decades that these flows have raised financial stability challenges across emerging economies including Turkey. Regarding the ability of the central banks to decrease the financial risks including volatile exchange rate, the Central Bank of the Republic of Turkey has designed and implemented a new policy mix. In this study, we investigated the effect of new policy instruments (IRC, RRR and ROM) on the volatilities of US dollar, euro, British pound and basket rate for Turkish economy between January 2, 2002 and December 9, 2014 by using ARMA-GARCH, ARMA-EGARCH and SWARCH models. From the estimation results, we could not reach enough evidence that the IRC and RRR instruments could decrease the volatilities of exchange rates under investigation while the ROM instrument was successful, especially on US dollar and basket rate. We also found strong evidence in favour of asymmetric volatility, indicating that the positive shocks led to greater exchange rate volatility than negative ones.     

An analysis of extreme movements of exchange rates of the main currencies traded in the Foreign Exchange market

This article analyses the extreme movements of exchange rates of the seven main currencies traded in the Foreign Exchange market against the US dollar: Euro, British pound, Canadian dollar, Japanese Yen, Swiss franc, Australian dollar and New Zealand dollar by using tail index indicators. Payaslio?lu (2009) considers the case of the Turkish exchange rate using the traditional Hill (1975) estimator as a tool. In this article, we employ also an alternative estimator proposed in Iglesias and Linton (2009) that is shown to have, in some cases, improved finite sample properties and it provides substantially different results versus the Hill estimator. We find that for the Euro, Japanese Yen, Swiss franc, Canadian, Australian and New Zealand dollars, the Hill estimator provides a better measure to analyse the extreme behaviour; while for the British pound, the Iglesias and Linton alternative estimator is superior by using Hausman-type tests of misspecification. Measures of value at risk are also provided for the seven markets. We also find that the largest estimated value at risk by far is for the Japanese Yen, followed by the Swiss franc, the Canadian dollar, the Euro, the New Zealand dollar and the Australian dollar. The UK pound has the smallest value at risk when extreme movements occur.     

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.     

Testing exchange rate efficiency: the case of euro–dollar

This paper tests the semi‐strong efficiency of the euro–dollar currency market by introducing a simple heuristic test, based on the ‘general‐to‐specific’ methodology and meant to include as two specific sub‐cases the ‘efficient market hypothesis’ (EMH) in the currency market as well as alternative theories implying a time dependent process of propagation of information. According to the results of our nested test, the ‘efficient market hypothesis’ in the euro–dollar currency market is rejected.     

A model of exchange rate policy: evidence for the US dollar–Greek drachma rate 1975–87

This paper represents an attempt to model movements of the exchange rate between the US dollar and Greek drachma. A stuctural model is set up, and then a reduced-form error correction(EC) speicifcation is derived. On the basis of co-integration test, the results do not support the existence of al long-run equilibrium relationship between the exchange rate and price differential. Furthermore, the instrumental variable estimation of the EC model indicates that the monetary authorities have pursued a short-run anti-inflationary exchange rate poilicy that appreciates the exchange rate in the presence of wage inflation as an attempt to mitigate the depreciating pressures on the domestic currency and thus to ease the adjustment required on Greek producers.     

Why does the peso-dollar exchange rate show a depreciation trend? The role of productivity differentials

Over the last three decades, Mexico's macroeconomic policy has been driven by a sound orthodox strategy: an open economy via many trade agreements signed since the mid-1980s, a nominal exchange rate under a flexible regime since 1994, central bank autonomy, and responsible fiscal policy, among other benchmarks. Nevertheless, the exchange rate has continued on a path of depreciation against the US dollar. In this paper, we show that although an equilibrium relationship exists between the exchange rate and prices in Mexico and the US (its main commercial partner), there are other forces affecting the former. The main factor in this relentless long-term depreciation is the loss of productivity in Mexico relative to the US. In addition, we show that the extraordinary liquidity supplied by the US during the 2008 crisis caused the Mexican peso to appreciate against the dollar.     

China’s equilibrium exchange rate dynamics 1994–2004: A cointegration analysis

Motivated by the global debate on the possible revaluation of the Chinese currency, the RMB, in recent years, the objective of this paper is to measure the equilibrium value of the RMB exchange rate through the macroeconomic balance approach in order to produce an assessment of the RMB in terms of periods of misalignment. The empirical evidence indicates that although there turns out to be an increasing degree of the RMB undervaluation in these measures from 2003 to 2004, the RMB is not substantially undervalued in both measures of real effective exchange rates and nominal bilateral exchange rates against the US dollar over the full period 1994–2004.     

Do foreign exchange forecasters apply asymmetric loss functions? Evidence from three major exchange rates

This article investigates which type of loss function is consistent with the hypothesis that major exchange rate forecasts, i.e. the euro, the British pound, and the Japanese yen vis-à-vis the US dollar, are rational. We apply a comprehensive data set, which also allows us to examine different forecast horizons and heterogeneity of forecasters.     

Trend shifts in the forward premium and the predictability of excess returns in currency markets

This article provides evidence that the forward premium involves structural changes in the trend function, which might affect the predictability of currency excess returns to be dependent on the choice of the sample period. Accounting for the shifts in trend for the forward premium reveals that currency excess returns for the Canadian dollar, Swiss franc, euro and pound against the US dollar are significantly predictable irrespective of the sample period selected. Another advantage of detrending the forward premium is that we can obtain more consistent slope coefficient estimates in the predictive regression, which enables us to make more consistent, dependable inferences about the excess return predictability.     

A risk-driven approach to exchange rate modelling

The paper presents a new approach to exchange rate modelling that augments the CHEER model with a sovereign credit default risk as perceived by financial investors making their decisions. In the cointegrated VAR system with nine variables comprised of the short- and long-term interest rates in Poland and the euro area, inflation rates, CDS indices and the zloty/euro exchange rate, four long-run relationships were found. Two of them link term spreads with inflation rates, the third one describes the exchange rate and the fourth one explains the inflation rate in Poland. Transmission of shocks was analysed by common stochastic trends. The estimation results were used to calculate the zloty/euro equilibrium exchange rate.     

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.     

Explaining the early years of the euro exchange rate: An episode of learning about a new central bank

Many observers were surprised by the depreciation of the euro after its launch in 1999. Handicapped by a short sample, explanations tended to appeal to anecdotes and lessons learned from the experiences of other currencies. Now sample sizes are just becoming large enough to permit reasonable empirical analyses. The model of this paper provides empirical support for the euro exchange rate to be affected by learning. By focusing on euro-area inflation as the key fundamental, the model is structured toward the dynamics of learning about ECB policy with regard to inflation. While a stated target inflation rate of 2 percent existed, it may be that market participants had to be convinced that the ECB would, indeed, generate low and stable inflation. With a prior distribution drawn from the pre-euro EMS experience and updating based upon the realized experience each month following the introduction of the euro, the evidence suggests that it was not until December of 1999 that the market assessed a greater than 50 percent probability that the inflation process had changed to a new regime. From this point on, trend depreciation of the euro ends and further increases in the probability of the new inflation process are associated with euro appreciation versus the US dollar, the British pound and the Japanese yen.     

Productivity Trends and the Sterling Real Exchange Rates*

This paper provides favorable econometric evidence for a productivity‐based model of the pound/euro real exchange rate. We find that a 1% increase in UK productivity is consistent with a 3.5% real depreciation of sterling. Likewise, a 1% increase in euro area productivity is compatible with a 5.16% real appreciation of sterling. The asymmetric response of UK and foreign productivity shocks corresponds well with our model if UK labor supply is more elastic than euro area labor supply. Estimates of equilibrium exchange rates suggest that sterling was not overvalued at its 2004Q3 level vis‐à‐vis the euro.     

Tobin Tax and Volatility: A Threshold Quantile Autoregressive Regression Framework

From an original data set on the euro–dollar and on the won–dollar currency pairs (2008–2010), we conduct a threshold quantile autoregressive model to explain the role of a Tobin tax (TT) on the exchange rate volatility, taking into account two types of nonlinearity (regimes and quantiles). We find evidence that the impact of a TT would not be monotonic. A TT may be a good instrument to stabilize foreign exchange volatility only in normal times and/or in efficient markets. In contrast, a TT could be counterproductive in turbulent periods by increasing the volatility. In addition, by comparing a major currency pair (euro/dollar) and a minor currency pair (won/dollar), it appears that the potential stabilizing effect of a TT would be more clear‐cut in the low volatility regime of a major currency pair, similar to the euro/dollar. Our results do not corroborate the previous studies that derived a monotonic and positive impact of a TT on volatility.
