Exchange Rate Overshooting

Table of Contents Heading

When countries hit the constraint they are forced to sell domestic assets, and this causes a further devaluation of the currency and a reduction of their stock prices . There are plausible parameter values under which fixed exchange rates dominate flexible exchange rates from a welfare perspective.

Macroeconomics studies an overall economy or market system, its behavior, the factors that drive it, and how to improve its performance. The sticky wage theory hypothesizes that pay of employees tends to have a slow response to the changes in the performance of a company or of the economy. While the ECB’s Jan. 21 meeting described financial conditions as “appropriate”, bond yields have risen since then and bank lending standards have tightened, says AXA chief economist Gilles Moec. In contrast to the United States, euro area economic recovery is underwhelming — the European Commission now expects 2021 growth at 3.8% versus a previous 4.2%. Of the components comprising FCIs, the dollar and 10-year bond yields have risen this year.

Some empirical analysis suggests that real exchange rate overshooting after currency crises assumes serious dimensions in nations with high volumes of foreign debt. Here overshooting phenomenon is associated with massive output contractions, which has far-reaching results for the economy in concern. Financial distortions resulting from margin constraints and lack of hedging results in overshooting of asset prices as well as real exchange rates under regimes of flexible exchange rates during a crisis. Margin constraint results in a rapid sale ofassetsin a bid to diminish exposure to foreign currency liability. This results in a negative wealth effect, which affects long-term welfare and consumption in an adverse way.

While the current aggregate volatility levels are atypical, the COVID-19 impact may vary among currencies according to their market standing, risk sensitivities, and the government’s policy response. For instance, the Australian dollar hit a 17-year low of $0.59215, and the New Zealand dollar an 11-year low of $0.5850 cents. On the other hand, the currencies viewed as safe havens, including the Japanese yen , traded at 107.42 yen per US$ while the Swiss Franc rose to US$ 0.9598 per CHF. Depending upon the concerned mode of analysis overshooting of key variables has different implications for an economy. One prime model of overshooting analysis is that of exchange rate determination. (Dornbusch’s overshooting hypothesis has received much critical acclaim in economic circles).

Overshooting Is When Exchange Rates A Adjust More In

Before Dornbusch, economists generally believed that markets should, ideally, arrive at equilibrium, and stay there. Some economists had argued that volatility was purely the result of speculators and inefficiencies in the foreign exchange market, like asymmetric information, or adjustment obstacles. The changes in investor behavior across two time horizons will potentially transform market linkages and correlations. Thus, the fractal models can be used to further explore the fractal contagion effects caused by the COVID-19 pandemic. Moreover, investigating the primary source of the increase in multifractality to understand the psychological aspects of investment behaviors is potentially an interesting direction for future research.

Dornbusch Overshooting Model Definition

Instead, both camps are divided, and advocates of both fixed and floating rates find themselves with unaccustomed allies. xchange rates between currencies have been highly unstable since the collapse of the Bretton Woods system of fixed exchange rates, which lasted from 1946 to 1973. Under the Bretton Woods system, exchange rates (e.g., the number of dollars it takes to buy a British pound or German mark) were fixed at levels determined by governments. Under the “floating” exchange rates we have had since 1973, exchange rates are determined by people buying and selling currencies in the foreign-exchange markets. The instability of floating rates has surprised and disappointed many economists and businessmen, who had not expected them to create so much uncertainty.

More generally, the currency vs. interest-bearing assets decision doesn’t have many implications for foreign exchange markets, if any. The simplest concept of purchasing-power-parity is the law of one price. It asserts that identical goods should be sold everywhere at the same price when converted to a common currency, assuming that it is costless to ship the good between nations, there are no barriers to trade, and markets are competitive.

Activist Monetary Policy And Exchange Rate Overshooting

In a seminal paper in 1953, Milton Friedman argued that the fear of floating exchange rates was unwarranted. Unstable exchange rates in the twenties, he maintained, were caused by unstable policies, not by destabilizing speculation. Friedman went on to argue that profit-maximizing speculators would always tend to stabilize, not destabilize, the exchange rate.

This paper provides a first look at forex market efficiency in the context of the COVID-19 pandemic as its economic and social costs are a matter of great concern to the society, policymakers, market operators, and individual investors. For this purpose, we conducted a comparative analysis of the efficiency level of six major currencies traded in forex markets, namely, AUD, CAD, CHF, EUR, GBP, and the JPY. Our study is thus vital as it provides an insightful analysis of fractals in the six major international forex markets.

Since the final equilibrium point H is above the initial iso-CAB line CC, the current account balance increases. (See Chapter 20 “The AA-DD Model”, Section 20.8 “AA-DD and the Current Account Balance” for a description of CC.) If the CAB were in surplus at F, then the surplus increases; if the CAB were in deficit, then the deficit falls. Thus U.S. expansionary monetary policy causes an increase in GNP, a depreciation of the U.S. dollar, and an increase in the current account balance in a floating exchange rate system according to the AA-DD model.

Contractionary monetary policy will cause a reduction in GNP and a reduction in the exchange rate (E$/£), implying an appreciation of the U.S. dollar and a decrease in the current account balance. The U.S. expansionary monetary policy causes an increase in GNP, a depreciation of the U.S. dollar, and an increase in the current account balance in a floating exchange rate system according to the AA-DD model. U.S. contractionary monetary policy will cause a reduction in GNP and a reduction in the exchange rate, E$/£, implying an appreciation of the U.S. dollar and a decrease in the current account balance. Consider the upward shift of the AA curve due to the increase in the money supply.

Is Economics A Science?

Foreign exchange policy reaction mitigates the initial effects of monetary policy shocks on the exchange rate. As the effects of the monetary policy shocks are more prolonged than that of the foreign exchange policy reaction, the maximum effect is found in delay. Long run exchange rates are best explained by factors including real income differentials, inflation rate differentials, productivity changes and trade barriers. In the short run, exchange rates respond to real interest rate differentials, news about market fundamentals, and speculative opinion about future exchange rates.

This can be accomplished by selling A$1 for US$0.7733 and then converting the US$0.7733 into yen at the rate of 108.81 yen per US$ to get (108.81)(0.7733) or 84.14277 yen. B) adjust less in the short run than they need to for long-run equilibrium. A) adjust more in the short run than they need to for long-run equilibrium. He was an adviser to Bill Clinton during the 1992 presidential campaign. There are several different levels of detail that can be provided to describe the effects of this policy.

The instability of exchange rates in the seventies and eighties would not have surprised the founders of the Bretton Woods system, who had a deep distrust of financial markets. The previous experience with floating exchange rates had been marked by massive instability. In an influential study of that experience, published in 1942, Norwegian economist Ragnar Nurkse argued that currency markets were subject to “destabilizing speculation,” which created pointless and economically damaging fluctuations. In this section, we use the AA-DD model to assess the effects of monetary policy in a floating exchange rate system. Recall from Chapter 18 “Interest Rate Determination” that the money supply is effectively controlled by a country’s central bank. In the case of the United States, this is the Federal Reserve Board, or the Fed for short.

Expansionary Monetary Policy

In particular, many firms seem to have followed a strategy of “pricing to market” (i.e., keeping the prices of their exports stable in terms of the importing country’s currency). Significant examples are the prices of imported automobiles in the United States, which neither fell much when the dollar was rising nor rose much when it began falling.

If investors do not see any difference between holding euro-denominated and dollar-denominated securities, then the exchange rate will stay at e1. The US government effort to bring the exchange rate back to e0 will be unsuccessful. This is because from the viewpoint of investors, there is no change in the quantity of euros supplied. The only change has been in the ratio of euro-denominated and dollar-denominated securities held by investors; but if investors don’t differentiate between the two, that is a change that is not a real change. The instability of rates since 1973 has thus been a severe disappointment.

Exchange Rate

The efficiency difference might have its roots in how investors perceive currencies—as assets—and in the fundamentals that determine their underlying value. In any case, the price efficiency of any asset is based on the premise that its prices have incorporated all relevant information.

Before applying MF-DFA, we examine the inner dynamics of multifractality through seasonal and trend decompositions using loess. The largest effect is observed for the Australian dollar, which shows the highest efficiency before the COVID-19 pandemic, assessed in terms of low multifractality. The Canadian dollar and the Swiss Franc exhibit the highest efficiency during the COVID-19 outbreak. Our findings may help policymakers shape a comprehensive response to improve forex market efficiency during such a black swan event. Now the government decides that it wants a lower interest rate and therefore increases the money supply. This causes the supply curve to shift inward, because at the higher level of money supply, US prices will start to move up. Hence, at a given exchange rate, investors will be willing to supply fewer euros.

This kind of real exchange rate overshooting is absent in a fixed exchange rate regime. Forex market efficiency also depends on the policy response from governments on both fiscal and monetary aspects, which are subject to several factors linked to the prevailing economic and political environment, among others. For example, an unanticipated change in money supply may lead to exchange rate overshooting as consumer prices cannot move immediately to reflect the money supply change . Building on this analogy, we can argue that a temporary disequilibrium in the forex markets may represent the adjustment of prices to information received through a relatively faster channel. The COVID-19 pandemic emerging from China received a quick response from investors while adjustments by policymakers may take time due to the rather measured interventions such as the recent deployment of central bank dollar swap lines. A number of empirical studies have reported that exchange rates show a delayed overshooting in response to a monetary policy shock.

  • Indeed, while prices adjust slowly and monotonically to their new long-run levels, exchange rates “bounce around.” In a world with numerous economic shocks, this leads to a high volatility of exchange rates and a much smaller volatility of prices.

Dornbusch overshooting model is a monetary model for exchange rate determination. The main idea behind the overshooting model is that the exchange rate will overshoot in the short run, and then move to the long-run new equilibrium. The model was proposed to solve the forward discount puzzle as well as the observed high levels of exchange rate volatility. Specifically, inflation, operating through a portfolio effect, lowers nominal rates of interest in the initial stage of the mechanism.


The Southern Economic Association was founded in 1927 to further the education of scholars and the public in economic affairs. Toward this end, the organization seeks to stimulate interest in and disseminate results of recent research in theory, policy making, business practices, and regulation. Currently, SEA has approximately 1,000 members worldwide, and more than 1,000 additional institutional subscribers to the journal. The Association holds its annual conference meetings in November, and publishes quarterly the Southern Economic Journal. The Southern Economic Journal features original, refereed scholarly articles in all areas of economics as well as contributions on the pedagogy of economics. The journal also contains occasional invited papers such as the Distinguished Guest Lecture, and the Presidential Address from the annual conference of the Southern Economic Association .

It rests on the assumption that sellers will seek out the highest possible prices and buyers the lowest ones. The purchasing-power-parity theory predicts that a country’s currency will depreciate by an amount equal to the excess of domestic inflation over foreign inflation. The theory also predicts that a country’s exchange rate will appreciate by an amount equal to the excess of foreign inflation over domestic inflation. The theory does not consider the impact of international capital movements, and it suffers from the choice of an appropriate price index used in price calculations. The law of one price holds reasonably well for globally tradable commodities such as oil, metals, chemicals, and some agricultural crops. The law does not appear to apply well to non-tradable goods and services such as cab rides, housing, and personal services like haircuts. Dornbusch’s exchange rate overshooting hypothesis is a central building block in international macroeconomics.
