There are two different types of world currency unit in use today that have different origins and usages.
71-418: The WCU was proposed by Lok Sang Ho of Lingnan University, Hong Kong. The WCU was first intended to be the basis for denominating global bonds , a debt instrument that is issued globally and is subscribable by people and institutions around the world. Simply put, it is a GDP-weighted basket of key currencies each of which is indexed against inflation for the relevant countries. The WCU is defined with respect to
142-415: A Norway incorporated provider of a Correspondent banking hub platform for cross border banking payments and real-time settlement revealed it was in discussions for the issuance and distribution of WOCU currency. The World Currency Unit ( WCU ) is an indexed unit of account that stands for a unit of real global purchasing power . Since each unit by design represents a stable unit of purchasing power,
213-582: A base year, so that each unit represents the same global purchasing power as at that base year, when it is equal to US$ 1. If there is inflation, the WCU will be worth more than $ 1 after the base year, but will represent the same purchasing power. The unindexed basket, called the benchmark basket of key currencies, is the basis for the derivation of effective exchange rate indices that has been demonstrated to be both easy to compile and superior to most official effective exchange rate indices. Rhett Morson has advocated
284-561: A consequence of changes in key economic fundamentals. According to this method, the BEER is the RER that results when all the economic fundamentals are at their equilibrium values. Therefore, the total RER misalignment is given by the extent to which economic fundamentals differ from their long-run sustainable levels. In short, the BEER is a more general approach than the FEER, since it is not limited to
355-523: A continuous series. The formula for the valuation of the World Currency Unit has been revised since 2008 so that the GDP weights are now revised every year. While still retaining the meaning of a unit of global real purchasing power, the WCU can now be interpreted as a GDP-weighted basket of currencies, each indexed against domestic inflation. The GDP-weighted basket of currencies has now formed
426-457: A country's balance of payments. An overvalued RER means that the current RER is above its equilibrium value, whereas an undervalued RER indicates the contrary. Specifically, a prolonged RER overvaluation is widely considered as an early sign of an upcoming crisis, due to the fact that the country becomes vulnerable to both speculative attacks and currency crisis, as happened in Thailand during
497-475: A currency by shorting in order to force that central bank to buy their own currency to keep it stable. (When that happens, the speculator can buy the currency back after it depreciates, close out their position, and thereby make a profit.) For carrier companies shipping goods from one nation to another, exchange rates can often impact them severely. Therefore, most carriers have a CAF charge to account for these fluctuations. The real exchange rate ( RER )
568-738: A currency. For example, between 1994 and 2005, the Chinese yuan renminbi (RMB) was pegged to the United States dollar at RMB 8.2768 to $ 1. China was not the only country to do this; from the end of World War II until 1967, Western European countries all maintained fixed exchange rates with the US dollar based on the Bretton Woods system . But that system had to be abandoned in favor of floating, market-based regimes due to market pressures and speculation, according to President Richard M. Nixon in
639-399: A dollar in relation to yen is ¥141, or equivalently that the price of a yen in relation to dollars is $ 1/141. Each country determines the exchange rate regime that will apply to its currency. For example, a currency may be floating , pegged (fixed) , or a hybrid. Governments can impose certain limits and controls on exchange rates. Countries can also have a strong or weak currency. There
710-431: A hybrid. In free-floating regimes, exchange rates are allowed to vary against each other according to the market forces of supply and demand. Exchange rates for such currencies are likely to change almost constantly as quoted on financial markets , mainly by banks , around the world. A movable or adjustable peg system is a system of fixed exchange rates , but with a provision for the revaluation (usually devaluation) of

The WOCU offers a transparent, relatively stable currency quotation as a hub currency reference for cross border trade to reduce volatility and risk. It reacts to the economic growth and decline of constituent country economies, adjusting the prominence of their respective currencies. The WOCU

As a result, currencies become over-valued or under-valued, leading to excessive trade deficits or surpluses. Research on target zones has mainly concentrated on the benefit of stability of exchange rates for industrial countries, but some studies have argued that volatile bilateral exchange rates between industrial countries are in part responsible for financial crisis in emerging markets. According to this view
923-467: A stable Current account (balance of payments)current account balance. A nation with a trade deficit will experience a reduction in its foreign exchange reserves, which ultimately lowers (depreciates) the value of its currency. A cheaper (undervalued) currency renders the nation's goods (exports) more affordable in the global market while making imports more expensive. After an intermediate period, imports will be forced down and exports to rise, thus stabilizing
994-407: A unit of account, a trusted medium of exchange, and a reliable store of value, the purchasing power of money should be stable. Unfortunately, substances that exist by the bounty of nature, such as gold or silver, cannot have such property since their values fluctuate with changing supply and demand. This is the main motivation behind indexed units of account, of which Robert Shiller of Yale University

This generally results in the basket consisting of 15 separate currencies, the Euro currency being common to normally 6 nation states included in the WOCU basket. Review and approval of weighting adjustments is subject to a confirmation process overseen by

Market convention from the early 1980s to 2006 was that most currency pairs were quoted to four decimal places for spot transactions and up to six decimal places for forward outrights or swaps. (The fourth decimal place is usually referred to as a " pip "). An exception to this was exchange rates with a value of less than 1.000 which were usually quoted to five or six decimal places. Although there
1207-521: Is a principal proponent. To be meaningful in terms of stable global purchasing power, a WCU will have to represent a basket of global output. By definition, according to the initial proposal by Ho, the WCU represents the sum of the gross domestic products of key market economies in the world, namely the USA, the Eurozone and UK, Japan, Canada, and Australia. Addition of these GDPs , each in a separate currency,

The spot exchange rate is the current exchange rate, while the forward exchange rate is an exchange rate that is quoted and traded today but for delivery and payment on a specific future date. In the retail currency exchange market, different buying and selling rates will be quoted by money dealers. Most trades are to or from
1349-484: Is crucial for policymakers. Unfortunately, this variable cannot be observed. The most common method in order to estimate the equilibrium RER is the universally accepted Purchasing Power Parity (PPP) theory, according to which the RER equilibrium level is assumed to remain constant over time. Nevertheless, the equilibrium RER is not a fixed value as it follows the trend of key economic fundamentals, such as different monetary and fiscal policies or asymmetrical shocks between
1420-469: Is done by converting all GDPs into US dollar values in the base year. The sum of these GDPs are then scaled down to equal $ 100 in the base year. The scaling factor then becomes part of the definition of the WCU, as it defines the size of the GDP basket. It is envisaged that every 5 or 10 years, the WCU can be rebased, with the new series using a new base year spliced to the old series much like consumer price indices with different base years are spliced to form
1491-404: Is highly correlated to a country's level of business activity, gross domestic product (GDP), and employment levels. The more people that are unemployed , the less the public as a whole will spend on goods and services.

A speculator may buy a currency if the return (that is the interest rate) is high enough. In general, the higher a country's interest rates, the greater will be the demand for that currency. It has been argued that such speculation can undermine real economic growth, in particular since large currency speculators may deliberately create downward pressure on

Rather, national exchange rate regimes reflect political considerations. In floating exchange rate regimes, exchange rates are determined in the foreign exchange market , which is open to a wide range of different types of buyers and sellers, and where currency trading

Currencies over 5000 were usually quoted with no decimal places (for example, the former Turkish Lira). e.g. (GBPOMR : 0.765432 - : 1.4436 - EURJPY : 165.29). In other words, quotes are given with five digits. Where rates are below 1, quotes frequently include five decimal places.

It is the ratio of the number of units of a given country's currency necessary to buy a market basket of goods in the other country, after acquiring the other country's currency in the foreign exchange market, to the number of units of the given country's currency that would be necessary to buy that market basket directly in
1988-424: Is viewed as a normative measure of the RER since it is based on some "ideal" economic conditions related to internal and external balances. Particularly, since the sustainable CA position is defined as an exogenous value, this approach has been broadly questioned over time. By contrast, the BEER entails an econometric analysis of the RER behaviour, considering significant RER deviations from its PPP equilibrium level as
2059-420: The 1997 Asian financial crisis . On the other side, a protracted RER undervaluation usually generates pressure on domestic prices, changing the consumers' consumption incentives and, so, misallocating resources between tradable and non-tradable sectors. Given that RER misalignment and, in particular overvaluation, can undermine the country's export-oriented development strategy, the equilibrium RER measurement
2130-417: The foreign exchange market . Currencies can be traded at spot and foreign exchange options markets. The spot market represents current exchange rates, whereas options are derivatives of exchange rates. A country may gain an advantage in international trade if it controls the market for its currency to keep its value low, typically by the national central bank engaging in open market operations in

There is evidence that the RER generally reaches a steady level in the long-term, and that this process is faster in small open economies characterized by fixed exchange rates.

Consequently, the PPP doctrine has been largely debated during the years, given that it may signal a natural RER movement towards its new equilibrium as a RER misalignment. Starting from the 1980s, in order to overcome the limitations of this approach, many researchers tried to find some alternative equilibrium RER measures. Two of the most popular approaches in

A lower exchange rate lowers the price of a country's goods for consumers in other countries, but raises the price of imported goods and services for consumers in the low value currency country.
