Effective exchange rate index

Last updated

The effective exchange rate index describes the strength of a currency relative to a basket of other currencies. Although typically the basket is trade weighted, there are others besides the trade-weighted effective exchange rate index.

Ho (2012) proposed a new approach to compiling effective exchange rate indices. Under this approach, the effective exchange rate can be calculated as a ratio of the normalized exchange value of currency against the US dollar to the normalized exchange value of the benchmark currency basket against the US dollar. Normalized exchange rate refers to the current exchange rate divided by the exchange rate against the US dollar in the base year, which effectively scales up the exchange rate of a "small value" currency like the Japanese yen, worth a small fraction of a dollar, and scales down the exchange rate of a "big value" currency like the British pound, worth much more than a dollar. Thus, all standardized or normalized currencies in the base year are worth US$1 in the base year. The US dollar is used for convenience, but, in principle, any other currency could be used instead without affecting the results. The benchmark currency basket is a GDP-weighted basket of the major fully convertible currencies of the world. Since GDP data are available with a lag, the GDP weights used in Ho are GDPs dated two years ago. The use of GDP weights has been found to be superior to direct trade weights since countries with bigger GDPs will tend to attract imports from other countries, both direct and indirect.

Value of the benchmark currency basket at time t = Σ (GDP weight of currency i(dated 2 years ago from year of time t)* normalized exchange rate of currency i against the US dollar at time t;

Effective exchange rate of currency j = Normalized exchange rate of currency j against the US dollar/Value of the benchmark currency basket against US dollar Archived 2019-02-07 at the Wayback Machine

Ho's procedure allows effective exchange rate indices to be easily compiled for any country.

Special drawing rights are supplementary foreign exchange reserve assets defined and maintained by the International Monetary Fund (IMF). SDRs are units of account for the IMF, and not a currency per se. They represent a claim to currency held by IMF member countries for which they may be exchanged. SDRs were created in 1969 to supplement a shortfall of preferred foreign exchange reserve assets, namely gold and U.S. dollars. The ISO 4217 currency code for special drawing rights is XDR and the numeric code is 960.

<span class="mw-page-title-main">Inflation</span> Devaluation of currency over a period of time

In economics, inflation is a general increase in the prices of goods and services in an economy. This is usually measured using the consumer price index (CPI). When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation corresponds to a reduction in the purchasing power of money. The opposite of CPI inflation is deflation, a decrease in the general price level of goods and services. The common measure of inflation is the inflation rate, the annualized percentage change in a general price index. As prices faced by households do not all increase at the same rate, the consumer price index (CPI) is often used for this purpose.

Purchasing power parity (PPP) is a measure of the price of specific goods in different countries and is used to compare the absolute purchasing power of the countries' currencies. PPP is effectively the ratio of the price of a basket of goods at one location divided by the price of the basket of goods at a different location. The PPP inflation and exchange rate may differ from the market exchange rate because of tariffs, and other transaction costs.

A consumer price index (CPI) is a price index, the price of a weighted average market basket of consumer goods and services purchased by households. Changes in measured CPI track changes in prices over time. The CPI is calculated by using a representative basket of goods and services. The basket is updated periodically to reflect changes in consumer spending habits. The prices of the goods and services in the basket are collected monthly from a sample of retail and service establishments. The prices are then adjusted for changes in quality or features. Changes in the CPI can be used to track inflation over time and to compare inflation rates between different countries. The CPI is not a perfect measure of inflation or the cost of living, but it is a useful tool for tracking these economic indicators.

In macroeconomics and modern monetary policy, a devaluation is an official lowering of the value of a country's currency within a fixed exchange-rate system, in which a monetary authority formally sets a lower exchange rate of the national currency in relation to a foreign reference currency or currency basket. The opposite of devaluation, a change in the exchange rate making the domestic currency more expensive, is called a revaluation. A monetary authority maintains a fixed value of its currency by being ready to buy or sell foreign currency with the domestic currency at a stated rate; a devaluation is an indication that the monetary authority will buy and sell foreign currency at a lower rate.

An exchange rate regime is a way a monetary authority of a country or currency union manages the currency about other currencies and the foreign exchange market. It is closely related to monetary policy and the two are generally dependent on many of the same factors, such as economic scale and openness, inflation rate, the elasticity of the labor market, financial market development, and capital mobility.

The trade-weighted effective exchange rate index, a common form of the effective exchange rate index, is a multilateral exchange rate index. It is compiled as a weighted average of exchange rates of home versus foreign currencies, with the weight for each foreign country equal to its share in trade. Depending on the purpose for which it is used, it can be export-weighted, import-weighted, or total-external trade weighted.

The international dollar, also known as Geary–Khamis dollar, is a hypothetical unit of currency that has the same purchasing power parity that the U.S. dollar had in the United States at a given point in time. It is mainly used in economics and financial statistics for various purposes, most notably to determine and compare the purchasing power parity and gross domestic product of various countries and markets. The year 1990 or 2000 is often used as a benchmark year for comparisons that run through time. The unit is often abbreviated, e.g. 2000 US dollars or 2000 International$.

The trade-weighted US dollar index, also known as the broad index, is a measure of the value of the United States dollar relative to other world currencies.

As the U.S. Dollar gains value the index increases.

A fixed exchange rate, often called a pegged exchange rate, is a type of exchange rate regime in which a currency's value is fixed or pegged by a monetary authority against the value of another currency, a basket of other currencies, or another measure of value, such as gold.
