Interest expectations and exchange rates news

Using a new survey data set ofmatched exchange rate and interest rate expectations for eight currencies relative to the German mark, we examine empirically the relationship between exchange rate returns, news and risk premia. News on interest differentials enters significantly in equations for the difference between the spot rate and the lagged forward rate for the British pound, Japanese yen, Spanish peseta and the US dollar. An unexpected rise in the interest rate differential tends to strengthen the domestic exchange rate. For each of these currencies, we also find significant effects of our ex-ante measure of the risk premium. In addition, we investigate the effect of lagged interest rate differentials as proxy for the risk premium and find that they do not capture time-varying risk premia as is widely suggested in the literature, but probably capture a peso-problem, learning about a policy change, a market-inefficiency or a combination of these factors.     

Estimates of foreign exchange risk premia: a pricing kernel approach

The goal of this study is to measure market prices of risk and foreign exchange risk premia. Estimations of minimum variance pricing kernels permit to determine market prices of risk, which, in an international no-arbitrage framework, allow to measure foreign exchange risk premia. Market prices of risk are time-varying and surge during financial turmoils. Foreign exchange risk premia are on average small in comparison to interest rate differentials and exhibit significant variation from the early 1970s onwards, when the Bretton Woods exchange rate system collapsed. At times, foreign exchange risk premia dominate interest rate differentials.

Foreign currency debt, risk premia and macroeconomic volatility

This paper studies the relationships between foreign currency debt, macroeconomic volatility, and risk premia in a model of a small open emerging market economy. The external value of the local currency is counter-cyclical, so that foreign currency debt requires larger repayments than local currency debt in bad states of nature. The level of foreign currency-denominated debts, therefore, affects the volatility of aggregate demand and by extension of the exchange rate. Exchange rate volatility is in turn an important determinant of the risk premium on local currency debt. Finally, this risk premium is a major factor in the choice of local versus foreign currency for emerging market borrowers. The mutual endogeneity of foreign currency debt, risk premia, and macroeconomic volatility creates important feedback effects in the economy: small increases in international risk aversion may entail large amplification effects on macroeconomic volatility since domestic borrowers substitute towards cheaper but riskier foreign currency debt finance.     

Heterogeneous expectations in the foreign exchange market

In this study a regime-switching approach is applied to estimate the chartist and fundamentalist (c&f) exchange rate model originally proposed by Frankel and Froot (1986). The c&f model is tested against alternative regime-switching specifications applying likelihood ratio tests. Nested atheoretical models like the popular segmented trends model suggested by Engel and Hamilton (1990) are rejected in favour of the multi-agent model. Our findings turned out to be relatively robust when assessing the models sub-sample estimates and out-of-sample performance.JEL Classification: F31, F37, G12, G15 Correspondence to: S. Reitz     

Interest rate convergence, capital controls, risk premia and foreign exchange market efficiency in the EMS

This paper examines interest rate convergence between Germany and the other EMS countries. We argue that earlier tests of convergence based on cointegration are not informative, because cointegration only implies that a linear combination of interest rates is stationary. We show that a conclusive judgment about convergence can be made if interest rate differentials exhibit a trend towards zero during the period when convergence occurred, and if the cointegrating vector has unit coefficients. We then establish that convergence has taken place in the “hard” EMS period. We also attempt to identify the sources of nonstationarities in interest differentials by examining the existence of stochastic or deterministic trends in the expected rate of depreciation and in the risk premium. Finally, the possibility of market inefficiencies is discussed.     

Bond risk premia, macroeconomic fundamentals and the exchange rate

We propose a two-country no-arbitrage term-structure model to analyze the joint dynamics of bond yields, macroeconomic variables and the exchange rate. The model allows to understand how exogenous shocks to the exchange rate affect the yield curves, how bond yields co-move in different countries and how the exchange rate is influenced by interest rates, macro-economic variables and time-varying bond risk premia.Estimating the model with US and German data, we find that time-varying bond risk premia account for a significant portion of the variability of the exchange rate: apparently, a currency tends to appreciate when investors expect large capital gains on long-term bonds denominated in that currency. A number of other novel empirical findings emerge.     

Quasi-fundamental exchange rate variation

Summary. This paper uses a general equilibrium model to study the determination of the exchange rate in an economy with fundamental uncertainty. The model has steady state equilibria in which the exchange rate is constant. These equilibria may coexist with “quasi-fundamental” equilibria – nonstationary equilibria in which the exchange rate displays stochastic fluctuations that are correlated with the fluctuations in fundamental random variables. The quasi-fundamental equilibria are Pareto dominated by the corresponding constant-exchange-rate steady states. They also converge to these steady states, inevitably or with positive probability.

Expectation formation in the foreign exchange market: a time-varying heterogeneity approach using survey data

Using Consensus Economics survey data on JPY/USD and GBP/USD exchange rate expectations for the 3- and 12-month horizons over the period November 1989–December 2012, we first show that expectations fail the conventional tests of unbiasedness and do not exhibit a learning process towards rationality. Our approach is consistent with the economically rational expectations theory (Feige and Pearce, 1976), which states that information costs and agents’ aversion to misestimating future exchange rates determine the optimal amounts of information on which they base their expectations. The time variability of the cost/aversion ratios justifies at the aggregate level a representation of expectations as a linear combination of the traditional extrapolative, adaptive and regressive processes augmented by a forward market component, whose parameters are allowed to change over time. This mixed expectation model with unstable heterogeneity is validated by our Kalman filter estimation results for the two currencies and the two horizons considered. Although the relative importance of the ‘fundamentalists’ (‘chartists’) is found to increase (decrease) with the time-horizon, chartist behaviour appears to dominate fundamentalist behaviour for both horizons. Central bank intervention is then effective in stabilizing the foreign exchange markets if it encourages fundamentalist activity.     

Interest rate expectations and the exchange rate

This paper presents a model of exchange rate reactions to interest rate changes and explains the following complex interactions. An expected interest rate increase induces a current depreciation. If that increase is true in the next period, then the exchange rate appreciates more than the previous depreciation. If the increase is sustained, it leads to a final, though small, depreciation. The model explicitly takes into account capital gains and losses. As far as expectations are concerned, two types of agents are considered (chartist and fundamentalist), and expectations are formed in two different ways (rational and bandwagon effect). Simulations and some empirical evidence for the U.S. dollar support the implications of the model.This paper has benefitted from the comments of the participants at the Forty-Third International Atlantic Economic Conference in London, England, March 11–18, 1997.

Financial amplification of foreign exchange risk premia

Theories of financial frictions in international capital markets suggest that financial intermediaries' balance sheet constraints amplify fundamental shocks. We present empirical evidence for such theories by decomposing the U.S. dollar risk premium into components associated with macroeconomic fundamentals, and a component associated with financial intermediary balance sheets. Relative to the benchmark model with only macroeconomic state variables, balance sheets amplify the U.S. dollar risk premium. We discuss applications to financial stability monitoring.     

Modelling risk premia in CO2 allowances spot and futures prices

This article analyzes the modelling of risk premia in CO₂ allowances spot and futures prices, valid for compliance under the EU Emissions Trading Scheme (EU ETS). Similarly to electricity markets, a salient characteristic of CO₂ allowances is that the theory of storage does not hold, as CO₂ allowances only exist on the balance sheets of companies regulated by the scheme. The main result features positive time-varying risk premia in CO₂ spot and futures prices, which are strictly higher for post-2012 contracts (€6–9/ton of CO₂) than for Phase II contracts (€0–6/ton of CO₂). Contrary to Benth et al.'s (2008) for electricity markets, a positive relationship between risk premia and time-to-maturity is found in the EU ETS. As for relative differences between CO₂ futures and spot prices, CO₂ futures traded between + 1% (December 2008 contract) and + 33% (December 2014 contract) above spot prices during February 2008–April 2009. Contrary to Bessembinder and Lemmon (2002) for the electricity market, a positive relationship between risk premia and the variance/skewness of CO₂ spot prices is found. The futures-spot bias to the EU ETS explains around 1–6% of the variance of CO₂ futures premia.     

A prototype model of the foreign exchange market of Canada: Forecasting capital flows and exchange rates

A balance-of-payments structural model of the foreign exchange market of Canada, endogenizing capital flows, the spot and forward exchange rates and the entities of the monetary sector, is developed using quarterly data for 1971–81. The capital flows have been disaggregated into ten categories and the exchange rates of the Canadian dollar have been analysed against five major currencies. While the model does not adhere strictly to purchasing power or interest rate parity, it does recognize them and it also incorporates other economic fundamentals, expectations and risk. Government interventions, although generated endogenously, are quantified implicitly and globally. The model tracks the post-Bretton Woods in-sample experience and generates ex post predictions reasonably well.     

The Polish exchange rate system: A unit root and cointegration analysis

In October 1991 Poland has established a crawling peg regime in which the zloty is tied to a currency basket and devalued with a monthly rate of crawl. If the monetary authorities are successful in defending the crawling peg the basket rate measured in Polish zloty is supposed to be stationary. Furthermore, a stable long-run relationship between the zloty-U.S. dollar rate and the basket's value expressed in U.S. dollar is expected to exist. The results of the unit root and cointegration analysis indicate that the monetary authorities have been able to defend the crawling peg for the sample periods under study, although it seems that not all requirements of the exchange rate regime have been met. The foreign exchange markets, however, have not supported the relationships derived from the crawling peg system after the introduction of the free floating system in April 2000.The final version of this paper has been prepared while I was a Jean Monnet Fellow at the European University Institute.

Estimating exchange rate dynamics with diffusion processes: an application to Greek EMU data

Recently various exchange rate models capturing the dynamics during the transition from an exchange rate arrangement of floating rates into a currency union have been derived. Technically, these stochastic equilibrium models are diffusion processes which have to be estimated by discretely sampled observations. Using daily exchange rate data prior to the Greek EMU-entrance on 1 January 2001, we develop a rigorous estimation procedure. Our estimates point to an increasing interventionist economic policy in the run-up to the Greek EMU entrance. A comparison of this econometric indication with policy information provided (ex-post) by the Bank of Greece (BoG) in its Annual Report 2000 reveals that the BoG indeed pursued such an active policy stance (so-called institutional frontloading strategies).      

Friction model and foreign exchange market intervention

The friction model is consistent with the hypothesis that a central bank intervenes in a foreign exchange market only if the necessity grows beyond certain thresholds. For this feature, the model is adopted in some recent studies as an attractive central bank reaction function. However, with official data on Federal Reserve and Bundesbank intervention, this paper shows that the friction model's advantage relative to a linear model may be negligible in terms of RMSE and MAE of in-sample fitting and out-of-sample forecasts. The implication is that intervention decisions are at the monetary authorities' discretion rather than dictated by a rule.     

Real exchange rate volatility,financial crises and exchange rate regimes

This article examines real exchange rate (RER) volatility in 80 countries around the world, during the period 1970 to 2011. Two main questions are raised: are structural breaks in RER volatility related to changes in exchange rate regimes or financial crises? And do these two events affect the permanent and transitory components of RER volatility? To answer these, we employ two complementary procedures that consist in detecting structural breaks in the RER series and decomposing volatility into its permanent and transitory components. Our results suggest that structural breaks in RER volatility coincidence with financial crises and certain changes in nominal exchange rate regimes. Moreover, our findings confirm that RER volatility does increase with the global financial crises and detect that the more flexible the exchange rate regime, the higher the volatility of the RER using a de facto exchange rate classification.     

Fixed exchange rate credibility with heterogeneous expectations

After disinflation has been achieved, agents who form more sophisticated forecasts have lower confidence in the sustainability of a peg compared to less sophisticated agents. Furthermore, sustained financial stability leads to a declining proportion of sophisticated agents. Thus, the credibility of a fixed exchange rate regime grows over time partly because fewer people pay attention to the workings of the monetary regime. These results are derived in a rules-versus-discretion model of a fixed exchange rate regime with heterogeneous agents. We provide unique supporting evidence using data on expectations and information about the monetary regime from Bulgaria’s currency board.     

Exchange rate models and exchange rate expectations: an empirical investigation

A non parametrictest of popular modern exchange rate models under alternative expectation specifications is presented. It is found that there is little difference in the predictive success of the alternative exchange rate models, however, there are significant differences in the performance of a model depending upon the expectations mechanism specified. Our most important finding is that the flexible price monetary model, the portfolio balance model and a hybrid model under extrapolative and adaptive expectations mechanisms provide statistically significant information about the direction of exchange rate movements. By contrast, the same models when employing static, regressive and rational expectation mechanisms do not provideany satistically significant information.     

Communication and exchange rate policy

Monetary authorities in the G3 economies have shifted in recent years towards communication as their primary policy tool to influence exchange rates. The paper assesses the effectiveness of communication, or oral interventions, by the G3 monetary authorities. It provides two key findings. First, G3 communication policies have constituted an effective policy tool in influencing exchange rates in the desired direction. And second, communication has been effective independently from the stance and direction of monetary policy and the occurrence of actual interventions. By contrast, the effectiveness of communication is strongly related to the degree of uncertainty and the positioning of participants in FX markets. Taken together, the results provide support for micro-based approaches to exchange rate modeling and are consistent with the argument that interventions affect exchange rates primarily through a coordination channel rather than a signaling channel.
