This fixed exchange rate has some impor­tant advantages and disadvantages:

1. Advantages:

(i) Elimination of Uncertainty and risk:

The necessary condition for an orderly and steady growth of trade demands stability in exchange rate.

Any undue fluctuations in exchange rate cause problems to the plans and programmes of both exporters and imports.

In other words, incomes of export-earners and the cost of im­ports of the importers tend to become uncer­tain if the exchange rate fluctuates. This un­certainty can be removed by a fixed exchange rate method. Further, the risks associated with international trade and investment get mini­mised largely, if exchange rates are not al­lowed to vary.

(ii) Speculation Deterred:


As the exchange rate remains unchanged for a fairly long pe­riod of time people expect that such rate would not change in the immediate future. This then eliminates speculation in the foreign exchange market.

Further, as stability in the exchange rate over longish periods eliminates the threat of speculation, it discourages flight of capital. In a world of free fluctuating exchange rate the danger of the flight of capital is rather high as this kind of exchange rate induces people to speculate.

(iii) Prevention of Depreciation of Currency:

In poor developing countries, one experiences BOP difficulties of a permanent type. Under the circumstances, any frequent changes in exchange rate will tend to aggravate the BOP crisis, like continuous depreciation of home currency in terms of currencies of other coun­tries. In other words, unstable exchange rates result in depreciation of currencies. This can be prevented by the stable exchange rate.

(iv) Adoption of Responsible Macroeco­nomic Policies:

Stable exchange rate system prevents government from adopting irrespon­sible macroeconomic policies like devaluation of currencies. Above all, under the fixed ex­change rate system, deflationary policies can even be pursued to tide over BOP deficit, even without bringing any change in domestic poli­cies.

(v) Attraction of Foreign Investment:


Ex­change rate stability may encourage foreign­ers to perk their investible funds in a country. If the exchange rate changes rather frequently, it will deter them to invest in a country. Of course, such foreign investment having mul­tiplier effect leads to higher economic growth.

(vi) Anti-Inflationary:

Fixed exchange rate system is anti-inflationary in character. If ex­change rate is allowed to decline, import goods tend to become dearer. High cost import goods then fuels inflation. Such a situation can be prevented by making the exchange rate fixed.

2. Disadvantages:

(i) Speculation Encouraged:

In fact, uncer­tainty and, hence, speculative activities, tend to get a boost even under the fixed rate sys­tem. Under a fixed rate system, if a country faces huge BOP deficit then the possibility of speculation gets brightened. If speculators guess that such BOP deficit will persist in the days ahead and the authority may go for a cut in foreign exchange rate then these specula­tors will be encouraged to sell domestic cur­rencies in the foreign exchange market.

If such sell of home currencies continue for a longer period, the central bank will then be forced to reduce exchange rate, instead of keeping it at the old fixed rate. Under the circumstance, speculators go on buying home currencies where exchange rates have been reduced. This will make these people to earn profit. Bretton Woods system of the IMF collapsed in 1971 because of such speculation made with the US dollars.

(ii) Adequacy of Foreign Exchange Reserves:


For the effectiveness of stable exchange rate, the necessary condition is the adequacy of holding foreign exchange reserves. Poor, de­veloping countries find it difficult to maintain an adequate volume of foreign exchange re­serves. Speculators then anticipate currency devaluation in advances if BOP needs to be corrected. Before 1970, fixed exchange rate, in fact, prevailed because of low volume of glo­bal trade and, hence, low volume of foreign exchange reserves.

(iii) Internal Objectives of Growth and Full Employment Sacrificed:

When countries ex­perience large and persistent deficits or ‘fun­damental disequilibrium’ in BOP, they are down with foreign exchange reserves. Coun­tries then opt for devaluation of their curren­cies and take some internal measures to re­duce their deficits. These harsh internal meas­ures tend to contract economies. But the fall­outs of these measures are rising prices and rising unemployment. These then reduce eco­nomic growth.

Thus, fixed exchange rate in the ultimate analysis go for currency depre­ciation that results in lower economic growth and higher unemployment coupled with high inflation—the two most undesirable and unpleasant macroeconomic variables not liked by anyone.

(iv) International Competitive Environment Bypassed:

The continuous changes in inter­national competitive environment do not get reflected under the fixed exchange rate sys­tem. Thus, to make the home product more competitive in the foreign market, what is re­quired is the change in domestic economic policies so that country’s export products get larger foothold in the foreign market. In other words, fixed exchange rate system fails to gloss over the international competitive envi­ronment.

This kind of exchange rate developed after the World War II. The International Mon­etary Fund set up by the Bretton Woods Agreement of 1944 came into operation in March 1947. The period 1947-1971 came to be known as ‘fixed but adjustable exchange rate system’ or ‘par value system’ or ‘pegged ex­change rate system’, or ‘Bretton Woods sys­tem.

As the Bretton Woods system collapsed this exchange rate was abandoned in 1971. Several stopgap measures were taken but un­certainty and confusion in exchange rate sys­tem continued. Ultimately, in 1973, the world’s exchange rate system came to be known as ‘managed floating’—in the sense that curren­cies tend to float more or less freely in the for­eign exchange market.
