Book excerpt: This paper uses a rich new data set of option prices on the dollar-mark, dollar-yen, and key EMS cross-rates to extract the entire risk-neutral probability density function (pdf) over horizons of one and three months. We compare three alternative smoothing methods--cubic splines, an implied binomial tree (trimmed and untrimmed), and a mixture of lognormals--for transforming option data into the pdf. Despite their methodological ifferences, the three approaches lead to a similar pdf distinct from the lognormal benchmark, and usually characterized by skewness and leptokurtosis. We then document a striking positive correlation between skewness in these pdfs and the spot rate. The stronger a currency the more expectations are skewed towards a further appreciation of that currency. We interpret this finding as a rejection that these exchange rates evolve as a martingale, or that they follow a credible target zone, explicit or implicit. Instead, this this positive correlation is consistent with target zones with endogenous realignment risk. We discuss two interpretations of our results on skewness: when a currency is stronger, the actual probability of further large appreciation is higher, or because of risk, such states are valued more highly.

Book Synopsis Foreign Exchange Options and the Economics of Exchange Rates by : Ranganai Gwati
Download or read book Foreign Exchange Options and the Economics of Exchange Rates written by Ranganai Gwati and published by . This book was released on 2015 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chapter 1: Historically, the currency derivative pricing literature and the macroeconomics literature on FX determination have progressed separately. In this Chapter I argue the joint study of these two strands of literature and give an overview of FX option pricing concepts and terminology crucial for this interdisciplinary study. I also explain the three sources of information about market expectations and perception of risk that can be extracted from FX option prices and review empirical methods for extracting option-implied densities of future exchange rates. As an illustration, I conclude the Chapter by investigating time series dynamics of option-implied measures of FX risk vis-a-vis market events and US government policy actions during the period January 2007 to December 2008. Chapter 2: This Chapter proposes using foreign exchange (FX) options with different strike prices and maturities to capture both FX expectations and risks. We show that exchange rate movements, which are notoriously difficult to model empirically, are well-explained by the term structures of forward premia and options-based measures of FX expectations and risk. Although this finding is to be expected, expectations and risk have been largely ignored in empirical exchange rate modeling. Using daily options data for six major currency pairs, we first show that the cross section options-implied standard deviation, skewness and kurtosis consistently explain not only the conditional mean but also the entire conditional distribution of subsequent currency excess returns for horizons ranging from one week to twelve months. This robust empirical pattern is consistent with a representative expected utility maximizing investor who, in addition to caring about the mean and variance, also cares about the skewness and kurtosis of the return distribution. Our results highlight the importance of expectations and risk in explaining exchange rate dynamics and suggest that the perennial problems faced by the empirical exchange rate literature are most likely due to overly restrictive auxiliary assumptions inherent in prevailing testing methods. Chapter 3: Standard ordinary least squares (OLS)-based tests of the uncovered interest parity (UIP) condition often make strong auxiliary assumptions beyond the joint hypotheses of rational expectations and risk-neutrality. This paper proposes using prices of foreign exchange (FX) option with different strike prices to test the time-varying risk premia explanation of the UIP puzzle. The options-based testing framework rests on the theoretical result that the forward exchange rate is the theoretical first moment of the option-implied distribution of future spot exchange rate. The framework allows us to test a more general version of FX market efficiency, which is the hypothesis that the option-implied risk-neutral distribution is an unbiased predictor of the future realized distribution of future spot rate. For five currency pairs, I do not reject the null hypothesis of UIP using the options-based approach.
Book Synopsis The Distribution of Exchange Rate Volatility by : Torben G. Anderson
Download or read book The Distribution of Exchange Rate Volatility written by Torben G. Anderson and published by . This book was released on 1999 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Using high-frequency data on Deutschemark and Yen returns against the dollar, we construct model-free estimates of daily exchange rate volatility and correlation, covering an entire decade. In addition to being model-free, our estimates are also approximately free of measurement error under general conditions, which we delineate. Hence, for all practical purposes, we can treat the exchange rate volatilities and correlations as observed rather than latent. We do so, and we characterize their joint distribution, both unconditionally and conditionally. Noteworthy results include a simple normality-inducing volatility transformation, high contemporaneous correlation across volatilities, high correlation between correlation and volatilities, pronounced and highly.
Book Synopsis The Distribution of Exchange Rates in the EMS by : Charles Engel
Download or read book The Distribution of Exchange Rates in the EMS written by Charles Engel and published by . This book was released on 1994 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exchange rates of currencies in the Exchange Rate Mechanism of the EMS are characterized by long periods of stability interrupted by periods of extreme volatility. The periods of volatility appear at times of realignments of the central parities and at times when the exchange rate is within the ERM bands. We begin by considering a procedure for finding outliers based on measuring distance as a quadratic form. The evidence suggests that the exchange rates of the EMS can be described by a mixture of two distributions. We therefore model the exchange rate as switching between two distributions--one that holds in stable times and the other that holds in volatile times. In particular, we use Hamilton's Markov-switching model. In addition, we extend Hamilton's model by allowing the probability of switching from one state to another to depend on the position of the exchange rate within its EMS band. This model has the interesting implication that near the edge of the band, large movements--either realignments or large jumps to the center of the band--are more likely if the move to the edge of the band has been precipitous.
Book Synopsis Deriving Market Expectations for the Euro-Dollar Exchange Rate from Option Prices by : Noureddine Krichene
Download or read book Deriving Market Expectations for the Euro-Dollar Exchange Rate from Option Prices written by Noureddine Krichene and published by International Monetary Fund. This book was released on 2004-10 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Option prices provide valuable information on market expectations. This paper attempts to extract market expectations, as conveyed by an implied risk-neutral probability distribution, from option prices for the dollar-euro exchange rate. Returns' volatilities are inferred from observed and interpolated option prices. To address robustness, two distributions, one from actual data and the other from interpolated data, were computed. The main conclusion of the paper is that traders have wide-ranging expectations, and large movements in either direction would not occur as a surprise. The main implication for monetary policy is that should markets become too volatile, then intervention may be required.
Book Synopsis Asset Market and Balance of Payments Characteristics by : Mr.Ronald MacDonald
Download or read book Asset Market and Balance of Payments Characteristics written by Mr.Ronald MacDonald and published by International Monetary Fund. This book was released on 1995-06-01 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper we use an exchange rate model that combines asset market characteristics with balance of payments interactions to examine the nominal effective exchange rates of the German mark, Japanese yen, and U.S. dollar for the recent experience with floating exchange rates. Our approach may be interpreted as one which attempts to flesh out the missing links that arise in conditioning an exchange rate solely on relative prices, as occurs in a standard PPP analysis. In contrast to much other empirical exchange rate modeling, our approach explicitly involves the use of a current account sustainability term. Amongst the findings reported in this paper are: significant, and sensible, long-run relationships for all of the currencies studied; appealing short-run dynamics for two of the currencies; and a finding that the Japanese effective exchange rate closely tracks the long-run exchange rate defined in this paper.

Book Synopsis Occasional Interventions to Target Rates with a Foreign Exchange Application by : Karen K. Lewis
Download or read book Occasional Interventions to Target Rates with a Foreign Exchange Application written by Karen K. Lewis and published by . This book was released on 1990 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper develops a framework for analyzing the effects upon rates when occasional central bank interventions try to keep rates near target levels. Interestingly, the threat of capital gains or losses induced by this stochastic intervention policy helps contain rates within implicit boundaries around the target level. More importantly, this intervention policy concentrates observations of the exchange rate around the target level and away from the implicit bands. In Monte Carlo simulations, sufficiently tight distributions for intervention around the target level imply that the bands are never reached in practice. As an application, the model is empirically evaluated using exchange rate and intervention observations following the 1987 Louvre accord. In these estimates, the probability of intervention never exceeds more than about .5 while the range of observed exchange rates remain far away from the implicit bands where the probability of intervention is one.
Book Synopsis Using Copulas to Construct Bivariate Foreign Exchange Distributions with an Application to the Sterling Exchange Rate Index by : Matthew Hurd
Download or read book Using Copulas to Construct Bivariate Foreign Exchange Distributions with an Application to the Sterling Exchange Rate Index written by Matthew Hurd and published by . This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "We model the joint risk-neutral distribution of the euro-sterling and the dollar-sterling exchange rates using option-implied marginal distributions that are connected via a copula function that satisfies the triangular no-arbitrage condition. We then derive a univariate distribution for a simplified sterling effective exchange rate index. Our results indicate that standard parametric copula functions, such as the commonly used Normal and Frank copulas, fail to capture the degree of asymmetry observed in the data. We overcome this problem by using a non-parametric dependence function in the form of a Bernstein copula which is shown to produce a very close fit. We further give an example of how our approach can be used to price currency index options."--Bank of England web site.
Book Synopsis Testing the Implied Volatility Smile of a Lognormal Distribution on a 6 - Month EUR/USD Call Currency Option Contract Using the Ratio of Strike and Share Price by : Michel Guirguis
Download or read book Testing the Implied Volatility Smile of a Lognormal Distribution on a 6 - Month EUR/USD Call Currency Option Contract Using the Ratio of Strike and Share Price written by Michel Guirguis and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We analyze the implied volatility smile of a lognormal distribution on a on a 6 - month EUR/USD call currency option contract using the ratio of strike and share price. There is significant time variation in the implied volatility smile and the traditional Black - Scholes model can not explain this deviation. The Black - Scholes model is used to calculate the theoretical call option price. Applying a lognormal implied distribution help us to price the contract at a market price and get better estimates of a risk adjusted measure. Deep in or out of the money contract has higher implied volatility. We have found that the 6 - month EUR/USD call currency option contract is overpriced relative to other call market prices. The 6 - month call contract with long maturity show low market standard deviation relative to the other call prices. Arbitrageurs check regularly the bid - ask spread to benefit from the mispricing. They check the steepness of the volatility smile to benefit from in the money call option.
