Fixed exchange-rate system

A fixed exchange rate, sometimes called a pegged exchange rate, is a type of exchange rate regime where a currency's value is fixed against either the value of another single currency, to a basket of other currencies, or to another measure of value, such as gold.

There are benefits and risks to using a fixed exchange rate. A fixed exchange rate is typically used in order to stabilize the value of a currency by directly fixing its value in a predetermined ratio to a different, more stable or more internationally prevalent currency (or currencies), to which the value is pegged. In doing so, the exchange rate between the currency and its peg does not change based on market conditions, the way floating currencies will do. This makes trade and investments between the two currency areas easier and more predictable, and is especially useful for small economies, economies which borrow primarily in foreign currency, and in which external trade forms a large part of their GDP.

A fixed exchange-rate system can also be used as a means to control the behavior of a currency, such as by limiting rates of inflation. However, in doing so, the pegged currency is then controlled by its reference value. As such, when the reference value rises or falls, it then follows that the value(s) of any currencies pegged to it will also rise and fall in relation to other currencies and commodities with which the pegged currency can be traded. In other words, a pegged currency is dependent on its reference value to dictate how its current worth is defined at any given time. In addition, according to the Mundell–Fleming model, with perfect capital mobility, a fixed exchange rate prevents a government from using domestic monetary policy in order to achieve macroeconomic stability.

In a fixed exchange-rate system, a country’s central bank typically uses an open market mechanism and is committed at all times to buy and/or sell its currency at a fixed price in order to maintain its pegged ratio and, hence, the stable value of its currency in relation to the reference to which it is pegged. The central bank provides the assets and/or the foreign currency or currencies which are needed in order to finance any payments imbalances.[1]

In the 21st century, the currencies associated with large economies typically do not fix or peg exchange rates to other currencies. The last large economy to use a fixed exchange rate system was the People's Republic of China which, in July 2005, adopted a slightly more flexible exchange rate system called a managed exchange rate.[2] The European Exchange Rate Mechanism is also used on a temporary basis to establish a final conversion rate against the Euro (€) from the local currencies of countries joining the Eurozone.

History

The gold standard or gold exchange standard of fixed exchange rates prevailed from about 1870 to 1914, before which many countries followed bimetallism.[3] The period between the two world wars was transitory, with the Bretton Woods system emerging as the new fixed exchange rate regime in the aftermath of World War II. It was formed with an intent to rebuild war-ravaged nations after World War II through a series of currency stabilization programs and infrastructure loans.[4] The early 1970s saw the breakdown of the system and its replacement by a mixture of fluctuating and fixed exchange rates.[5]

Gold standard

The earliest establishment of a gold standard was in the United Kingdom in 1821 followed by Australia in 1852 and Canada in 1853. Under this system, the external value of all currencies was denominated in terms of gold with central banks ready to buy and sell unlimited quantities of gold at the fixed price. Each central bank maintained gold reserves as their official reserve asset.[7] For example, during the “classical” gold standard period (1879–1914), the U.S. dollar was defined as 0.048 troy oz. of pure gold.[8]

Bretton Woods system

Following the Second World War, the Bretton Woods system (1944–1973) replaced gold with the U.S. dollar as the official reserve asset. The regime intended to combine binding legal obligations with multilateral decision-making through the International Monetary Fund (IMF). The rules of this system were set forth in the articles of agreement of the IMF and the International Bank for Reconstruction and Development. The system was a monetary order intended to govern currency relations among sovereign states, with the 44 member countries required to establish a parity of their national currencies in terms of the U.S. dollar and to maintain exchange rates within 1% of parity (a "band") by intervening in their foreign exchange markets (that is, buying or selling foreign money). The U.S. dollar was the only currency strong enough to meet the rising demands for international currency transactions, and so the United States agreed both to link the dollar to gold at the rate of $35 per ounce of gold and to convert dollars into gold at that price.[6]

Due to concerns about America's rapidly deteriorating payments situation and massive flight of liquid capital from the U.S., President Richard Nixon suspended the convertibility of the dollar into gold on 15 August 1971. In December 1971, the Smithsonian Agreement paved the way for the increase in the value of the dollar price of gold from US$35.50 to US$38 an ounce. Speculation against the dollar in March 1973 led to the birth of the independent float, thus effectively terminating the Bretton Woods system.[6]

Current monetary regimes

Since March 1973, the floating exchange rate has been followed and formally recognized by the Jamaica accord of 1978. Countries still need international reserves in order to intervene in foreign exchange markets to balance short-run fluctuations in exchange rates.[6] The prevailing exchange rate regime is in fact often considered as a revival of the Bretton Woods policies, namely Bretton Woods II.[9]

Mechanisms

Open market trading

Typically, a government wanting to maintain a fixed exchange rate does so by either buying or selling its own currency on the open market. This is one reason governments maintain reserves of foreign currencies. If the exchange rate drifts too far above the fixed benchmark rate, the government buys its own currency in the market using its reserves. This places greater demand on the market and causes the local currency to appreciate, thus pushing down the price of the currency. If the exchange rate drifts too far below the desired rate, the government sells its own currency and buys foreign currency, thus reducing the pressure on demand as its foreign reserves fall.

Fiat

Another, less used means of maintaining a fixed exchange rate is by simply making it illegal to trade currency at any other rate. This is difficult to enforce and often leads to a black market in foreign currency. Nonetheless, some countries are highly successful at using this method due to government monopolies over all money conversion. This was the method employed by the Chinese government to maintain a currency peg or tightly banded float against the US dollar. China buys an average of one billion US dollars a day to maintain the currency peg.[10] Throughout the 1990s, China was highly successful at maintaining a currency peg using a government monopoly over all currency conversion between the yuan and other currencies.[11][12]

Open market mechanism example

Fig.1: Mechanism of fixed exchange-rate system

Under this system, the central bank first announces a fixed exchange-rate for the currency and then agrees to buy and sell the domestic currency at this value. The market equilibrium exchange rate is the rate at which supply and demand will be equal, i.e., markets will clear. In a flexible exchange rate system, this is the spot rate. In a fixed exchange-rate system, the pre-announced rate may not coincide with the market equilibrium exchange rate. The foreign central banks maintain reserves of foreign currencies and gold which they can sell in order to intervene in the foreign exchange market to make up the excess demand or take up the excess supply [1]

The demand for foreign exchange is derived from the domestic demand for foreign goods, services, and financial assets. The supply of foreign exchange is similarly derived from the foreign demand for goods, services, and financial assets coming from the home country. Fixed exchange-rates are not permitted to fluctuate freely or respond to daily changes in demand and supply. The government fixes the exchange value of the currency. For example, the European Central Bank (ECB) may fix its exchange rate at €1 = $1 (assuming that the euro follows the fixed exchange-rate). This is the central value or par value of the euro. Upper and lower limits for the movement of the currency are imposed, beyond which variations in the exchange rate are not permitted. The "band" or "spread" in Fig.1 is €0.4 (from €1.2 to €0.8).[13]

Excess demand for dollars

Fig.2: Excess demand for dollars

Fig.2 describes the excess demand for dollars. This is a situation where domestic demand for foreign goods, services, and financial assets exceeds the foreign demand for goods, services, and financial assets from the European Union. If the demand for dollar rises from DD to D'D', excess demand is created to the extent of cd. The ECB will sell cd dollars in exchange for euros to maintain the limit within the band. Under a floating exchange rate system, equilibrium would have been achieved at e.

When the ECB sells dollars in this manner, its official dollar reserves decline and domestic money supply shrinks. To prevent this, the ECB may purchase government bonds and thus meet the shortfall in money supply. This is called sterilized intervention in the foreign exchange market. When the ECB starts running out of reserves, it may also devalue the euro in order to reduce the excess demand for dollars, i.e., narrow the gap between the equilibrium and fixed rates.

Excess supply of dollars

Fig.3: Excess supply of dollars

Fig.3 describes the excess supply of dollars. This is a situation where the foreign demand for goods, services, and financial assets from the European Union exceeds the European demand for foreign goods, services, and financial assets. If the supply of dollars rises from SS to S'S', excess supply is created to the extent of ab. The ECB will buy ab dollars in exchange for euros to maintain the limit within the band. Under a floating exchange rate system, equilibrium would again have been achieved at e.

When the ECB buys dollars in this manner, its official dollar reserves increase and domestic money supply expands, which may lead to inflation. To prevent this, the ECB may sell government bonds and thus counter the rise in money supply.

When the ECB starts accumulating excess reserves, it may also revalue the euro in order to reduce the excess supply of dollars, i.e., narrow the gap between the equilibrium and fixed rates. This is the opposite of devaluation.

Types of fixed exchange rate systems

The gold standard

Under the gold standard, a country’s government declares that it will exchange its currency for a certain weight in gold. In a pure gold standard, a country’s government declares that it will freely exchange currency for actual gold at the designated exchange rate. This "rule of exchange” allows anyone to go the central bank and exchange coins or currency for pure gold or vice versa. The gold standard works on the assumption that there are no restrictions on capital movements or export of gold by private citizens across countries.

Because the central bank must always be prepared to give out gold in exchange for coin and currency upon demand, it must maintain gold reserves. Thus, this system ensures that the exchange rate between currencies remains fixed. For example, under this standard, a £1 gold coin in the United Kingdom contained 113.0016 grains of pure gold, while a $1 gold coin in the United States contained 23.22 grains. The mint parity or the exchange rate was thus: R = $/£ = 113.0016/23.22 = 4.87.[6] The main argument in favor of the gold standard is that it ties the world price level to the world supply of gold, thus preventing inflation unless there is a gold discovery (a gold rush, for example).

Price specie flow mechanism

The automatic adjustment mechanism under the gold standard is the price specie flow mechanism, which operates so as to correct any balance of payments disequilibrium and adjust to shocks or changes. This mechanism was originally introduced by Richard Cantillon and later discussed by David Hume in 1752 to refute the mercantilist doctrines and emphasize that nations could not continuously accumulate gold by exporting more than their imports.

The assumptions of this mechanism are:

  1. Prices are flexible
  2. All transactions take place in gold
  3. There is a fixed supply of gold in the world
  4. Gold coins are minted at a fixed parity in each country
  5. There are no banks and no capital flows

Adjustment under a gold standard involves the flow of gold between countries resulting in equalization of prices satisfying purchasing power parity, and/or equalization of rates of return on assets satisfying interest rate parity at the current fixed exchange rate. Under the gold standard, each country's money supply consisted of either gold or paper currency backed by gold. Money supply would hence fall in the deficit nation and rise in the surplus nation. Consequently, internal prices would fall in the deficit nation and rise in the surplus nation, making the exports of the deficit nation more competitive than those of the surplus nations. The deficit nation's exports would be encouraged and the imports would be discouraged till the deficit in the balance of payments was eliminated.[14]

In brief:

Deficit nation: Lower money supply → Lower internal prices → More exports, less imports → Elimination of deficit

Surplus nation: Higher money supply → Higher internal prices → Less exports, more imports → Elimination of surplus

Reserve currency standard

In a reserve currency system, the currency of another country performs the functions that gold has in a gold standard. A country fixes its own currency value to a unit of another country’s currency, generally a currency that is prominently used in international transactions or is the currency of a major trading partner. For example, suppose India decided to fix its currency to the dollar at the exchange rate E₹/$ = 45.0. To maintain this fixed exchange rate, the Reserve Bank of India would need to hold dollars on reserve and stand ready to exchange rupees for dollars (or dollars for rupees) on demand at the specified exchange rate. In the gold standard the central bank held gold to exchange for its own currency, with a reserve currency standard it must hold a stock of the reserve currency.

Currency board arrangements are the most widespread means of fixed exchange rates. Under this, a nation rigidly pegs its currency to a foreign currency, special drawing rights (SDR) or a basket of currencies. The central bank's role in the country's monetary policy is therefore minimal as its money supply is equal to its foreign reserves. Currency boards are considered hard pegs as they allow central banks to cope with shocks to money demand.

Gold exchange standard

The fixed exchange rate system set up after World War II was a gold-exchange standard, as was the system that prevailed between 1920 and the early 1930s.[16] A gold exchange standard is a mixture of a reserve currency standard and a gold standard. Its characteristics are as follows:

Unlike the gold standard, the central bank of the reserve country does not exchange gold for currency with the general public, only with other central banks.

Hybrid exchange rate systems

The current state of foreign exchange markets does not allow for the rigid system of fixed exchange rates. At the same time, freely floating exchange rates expose a country to volatility in exchange rates. Hybrid exchange rate systems have evolved in order to combine the characteristics features of fixed and flexible exchange rate systems. They allow fluctuation of the exchange rates without completely exposing the currency to the flexibility of a free float.

Basket-of-currencies

Countries often have several important trading partners or are apprehensive of a particular currency being too volatile over an extended period of time. They can thus choose to peg their currency to a weighted average of several currencies (also known as a currency basket) . For example, a composite currency may be created consisting of hundred rupees, 100 Japanese yen and one U.S. dollar the country creating this composite would then need to maintain reserves in one or more of these currencies to satisfy excess demand or supply of its currency in the foreign exchange market.

A popular and widely used composite currency is the SDR, which is a composite currency created by the International Monetary Fund (IMF), consisting of a fixed quantity of U.S. dollars, Chinese yuan, euros, Japanese yen, and British pounds.

Crawling pegs

Main article: Crawling peg

In a crawling peg system a country fixes its exchange rate to another currency or basket of currencies. This fixed rate is changed from time to time at periodic intervals with a view to eliminating exchange rate volatility to some extent without imposing the constraint of a fixed rate. Crawling pegs are adjusted gradually, thus avoiding the need for interventions by the central bank (though it may still choose to do so in order to maintain the fixed rate in the event of excessive fluctuations).

Pegged within a band

A currency is said to be pegged within a band when the central bank specifies a central exchange rate with reference to a single currency, a cooperative arrangement, or a currency composite. It also specifies a percentage allowable deviation on both sides of this central rate. Depending on the band width, the central bank has discretion in carrying out its monetary policy. The band itself may be a crawling one, which implies that the central rate is adjusted periodically. Bands may be symmetrically maintained around a crawling central parity (with the band moving in the same direction as this parity does). Alternatively, the band may be allowed to widen gradually without any pre-announced central rate.

Currency boards

A currency board (also known as 'linked exchange rate system") effectively replaces the central bank through a legislation to fix the currency to that of another country. The domestic currency remains perpetually exchangeable for the reserve currency at the fixed exchange rate. As the anchor currency is now the basis for movements of the domestic currency, the interest rates and inflation in the domestic economy would be greatly influenced by those of the foreign economy to which the domestic currency is tied. The currency board needs to ensure the maintenance of adequate reserves of the anchor currency. It is a step away from officially adopting the anchor currency (termed as currency substitution).

Currency Substitution

This is the most extreme and rigid manner of fixing exchange rates as it entails adopting the currency of another country in place of its own. The most prominent example is the eurozone, where 19 European Union (EU) member states have adopted the euro (€) as their common currency (euroization). Their exchange rates are effectively fixed to each other.

There are similar examples of countries adopting the U.S. dollar as their domestic currency (dollarization): British Virgin Islands, Caribbean Netherlands, East Timor, Ecuador, El Salvador, Marshall Islands, Federated States of Micronesia, Palau, Panama, Turks and Caicos Islands and Zimbabwe.

(See ISO 4217 for a complete list of territories by currency.)

Advantages

Disadvantages

The main criticism of a fixed exchange rate is that flexible exchange rates serve to adjust the balance of trade.[18] When a trade deficit occurs under a floating exchange rate, there will be increased demand for the foreign (rather than domestic) currency which will push up the price of the foreign currency in terms of the domestic currency. That in turn makes the price of foreign goods less attractive to the domestic market and thus pushes down the trade deficit. Under fixed exchange rates, this automatic rebalancing does not occur.

Governments also have to invest many resources in getting the foreign reserves to pile up in order to defend the pegged exchange rate. Moreover, a government, when having a fixed rather than dynamic exchange rate, cannot use monetary or fiscal policies with a free hand. For instance, by using reflationary tools to set the economy rolling (by decreasing taxes and injecting more money in the market), the government risks running into a trade deficit. This might occur as the purchasing power of a common household increases along with inflation, thus making imports relatively cheaper.

Additionally, the stubbornness of a government in defending a fixed exchange rate when in a trade deficit will force it to use deflationary measures (increased taxation and reduced availability of money), which can lead to unemployment. Finally, other countries with a fixed exchange rate can also retaliate in response to a certain country using the currency of theirs in defending their exchange rate.

Other noted disadvantages:

Fixed exchange rate regime versus capital control

The belief that the fixed exchange rate regime brings with it stability is only partly true, since speculative attacks tend to target currencies with fixed exchange rate regimes, and in fact, the stability of the economic system is maintained mainly through capital control. A fixed exchange rate regime should be viewed as a tool in capital control.
