For about three decades until the Global Financial Crisis (GFC), Covered Interest Parity (CIP) appeared to hold quite closely—even as a broad macroeconomic relationship applying to daily or weekly data. Not only have CIP deviations significantly increased since the GFC, but potential macrofinancial drivers of the variation in CIP deviations have also become significant. The variation in CIP deviations seems to be associated with multiple factors, not only regulatory changes. Most of these do not display a uniform importance across currency pairs and time, and some are associated with possible temporary considerations (such as asynchronous monetary policy cycles).

Master's Thesis from the year 2016 in the subject Business economics - Banking, Stock Exchanges, Insurance, Accounting, grade: 1,0, University of Frankfurt (Main) (Goethe Business School), language: English, abstract: The aim of this thesis is to test UIP by implementing an OLS regression analysis for five currency pairs which, according to CFTC data, global turnover data and carry-to-risk ratios, were among the most popular in the investor community. To increase the significance of this thesis for practitioners, the work will use one-month forward contracts which are used frequently by investors and include bid and ask rates in order to account for transaction costs. In addition, all currency pairs include the US Dollar for reasons of better liquidity, and therefore tighter bid-ask spreads. Moreover, this thesis will present recent findings in literature which try to explain deviations from UIP. Approaches can be separated by the focus on a risk premium, by irrational market behavior or by learning problems and market inefficiency. While most focus is laid on an explanation by a risk premium, it will be shown that it is crucial to combine the different scientific disciplines in order to solve the forward premium puzzle. In addition to this, the thesis will provide an outlook on the future attractiveness of carry trade strategies.

This note provides an overview of the uncovered interest parity assumption. It traces the history of the interest parity concept, summarizes evidence on the empirical validity of uncovered interest parity, and discusses the implications for macroeconomic analysis. The uncovered interest parity assumption has been an important building block in multiperiod and continuous time models of open economies, and although its validity is strongly challenged by the empirical evidence, its retention in macroeconomic models is supported on pragmatic grounds, at least for the time being, by the lack of much empirical support for existing models of the exchange risk premium.

This paper presents a rule for foreign exchange interventions (FXI), designed to preserve financial stability in floating exchange rate arrangements. The FXI rule addresses a market failure: the absence of hedging solution for tail exchange rate risk in the market (i.e. high volatility). Market impairment or overshoot of exchange rate between two equilibria could generate high volatility and threaten financial stability due to unhedged exposure to exchange rate risk in the economy. The rule uses the concept of Value at Risk (VaR) to define FXI triggers. While it provides to the market a hedge against tail risk, the rule allows the exchange rate to smoothly adjust to new equilibria. In addition, the rule is budget neutral over the medium term, encourages a prudent risk management in the market, and is more resilient to speculative attacks than other rules, such as fixed-volatility rules. The empirical methodology is backtested on Banco Mexico’s FXIs data between 2008 and 2016.

This paper decomposes longer-run movements in (major) dollar real exchange rates into components associated with changes in nominal exchange rates and price levels, and their comovements. Though the decompositions suggest some permanent movements, they imply that there are large transitory components in real exchange rates. These transitory components in real exchange rates are found to be closely associated with those in nominal exchange rates. A stochastic version of Dornbusch’s overshooting model—configured with representative parameter values for the United States and subjected to permanent nominal shocks—can rationalize these transitory comovements of nominal and real exchange rates as well as several other features of the decompositions.
