Following the collapse of the Bretton woods system on August 15, 1971, the EEC countries agreed to maintain stable exchange rates by preventing exchange fluctuations of more than 2.25%. This arrangement was called "European snake in the tunnel" because the community currencies floated as a group against outside currencies such as the dollar.
By 1978, the snake turned into a worm (with only German mark, Belgian franc, Dutch guilder, Danish krone). However, a new effort to achieve monetary cooperation was launched. By March 1979, EC established European Monetary System, and created the European Currency Unit (ECU).
|European Monetary System||Prevent movements above 2.25 % around parity in bilateral exchange rates with other member countries.|
The European Monetary Cooperation Fund allocates ECUs to members' central banks in exchange for gold and dollar deposits. 20% of the quota must be paid in gold. ECU was an artificial currency and used in all intrasystem balance of payments settlements. ECU was replaced by euro (at 1:1) on January 1, 1999.
provision of credit facilities for compensatory financing.
Then the EMS created the European Central bank (June 1998) and a single European currency (euro 2002).
Since its inauguratation in 2002, euro has gained ascendancy and is valued at about $1.46 as of December 2007.
As a general rule, small countries (whose trade share is less than 1% of world trade) should peg their currency to a major currency or a basket of major currencies. But there is little harm in floating their currencies. The peg should be set at a level to ensure balanced trade. (Remember Greece's problem)
|Developing countries||There are some developing countries that rely heavily on exports of a few primary products. Also, countries that mostly trade with one country. In this case, pegging to a major currency is acceptable.|
Countries whose trade shares exceed 1- 2 % of world trade should adopt floating rates to insulate their economies from excessive foreign shocks. If trade share exceeds 5% of world trade, the country should definitely float its currency.
For example, China's export share is about 10%, and it should float yuan. In the foreseeable future (during this decade), four major currencies (USD, euro, yen and yuan) will float their currencies. India and Russia may follow suit eventually. Large countries may not only hurt themselves (profit from currency intervention will be negative) but also disrupt world trade when their currencies are pegged to another currency to gain a large trade surplus.
|Current system||Currencies of other industrial currencies are floating with respect to the dollar. Accordingly, the current system is a mixture of exchange rate arrangements.|
|Europe||10 European currencies were aligned within margins of 2.25%, but they jointly float against the dollar and others. Irish pound, Italian lira, Luxembourg Franc, German mark, Belgian Franc, Dutch gilder, French Franc, Danish Krone, Spanish peseta (plus British pound). Italian lira and Spanish peseta have wider margins of 6%. This arrangement was further simplified by the creation of euro, effectively creating the euro area.|
Swiss Franc, Canadian dollar, British pound, the Japanese yen and the U.S. dollar are floating.
The remaining currencies of LDCs pegged to major currencies or baskets.
Imports of East Asian countries are often invoiced in dollars. For example, about 70% of Japan's imports are invoiced in dollars. This dollar invoicing practically expands the dollar area to include Japan and other East Asian countries (Ronald McKinnon).
|dollar peg is declining||
As of 2008, 17 currencies of small countries are pegged to USD.
In addition to the euro zone of 15 countries, 23 currencies are pegged to euro.
As of 2007, 111 countries adopted fixed exchange rates. Specifically, 41 countries have no separate legal tender, 7 countries have currency boards, 52 countries have fixed pegs, 6 horizontal bands, and 5 crawing pegs.
76 countries adopted floating. (source: IMF)
|intervention has not declined||
The current system is a managed float, rather than pure or clean float.
Since 1973, the amount of compensatory financing or intervention of national monetary authorities has not declined (e.g., Japan, China).
|Reasons||(i) The response of imports and exports is not spontaneous,
but occurs only after a lag (which can take up to a year or more). During
the period of adjustment, some surpluses and deficits appear in the balance
of payments, which must be financed by the monetary authorities.
(ii) Wide fluctuations of exchange rates may have undesirable effects on inflation, employment and international competitiveness. Thus, central banks may go beyond smoothing daily and weekly fluctuations and maintain the exchange rates at target levels. (this is acceptable.) In this sense, the managed float resembles adjustable peg system.
(iii) In recent years, large countries (e.g., Japan and China) continue to hold large trade surpluses, instead of smoothing exchange rate fluctuations. (Profit from such currency intervention is negative)
|Beginning 1972, US and European countries
negotiated on the reform of the international monetary system. After four
years, an agreement on an amendment of the Articles was reached in Jamaica
in January 1976.
Floating of currencies had been forbidden under the Bretton Woods system, but was tentatively adopted as a temporary arrangement in 1973. Now the managed float is firmly established as it appeared as the only viable system for two reasons (i) continued growth of world trade without excessive fluctuations in exchange rates, (ii) the floating system coped with two oil crises with relative ease.
A new Article IV of Agreement was approved by the Board of Governors in April 1976, and was ratified by 2/3 of the member nations in 1978.
|second amendment (copy)||
the first amendment permitted creation of SDR.
The contents are:
(i) legitimizing floating rates. A member country is free to choose its own exchange rate system.
freely floating, managed float, pegged to a currency or a group of currencies or SDR. Not to gold.
(ii) The Fund will exercise surveillance over the exchange rate policies, and adopt specific principles to guide member countries.
(iii) By an 85% supermajority, the Fund may reintroduce a system of adjustable peg. However, a member may remain without a par value. (US can veto).
(iv) downgrade the monetary role of gold (gold cannot be used for international transactions).
(v) designate SDR as the principal reserve asset in the international monetary system.
(i) A member shall avoid manipulating exchange rates to prevent balance of payments adjustments or to gain unfair advantage over other countries. (e.g., do not devalue to maintain surplus)
|(ii) a member should intervene in the exchange markets if necessary to counter disorderly conditions.|
|(iii) A member should take into account the interests of other member countries, including the countries whose currencies they use to intervene.|
|Problem||IMF has little displinary power|
|Merits||(i) Managed floats have not reduced international trade and investment or caused a disintegration of international capital market.|
|(ii) have not resulted in quick adjustment in trade flows (deficits/surpluses persisted)|
|(iii) Pivotal role of $ has diminished (as prime reserve asset ⇒ SDR). Whether euro will play a major role remains to be seen. Due to China's pegging of yuan to USD, euro has steadily appreciated. This trend will continue until China stops its pegging to USD.|
(i) exchange rates have been volatile. Increasingly, there are economists who claim that there is overmuch instability.
(ii) IMF does not have any power to discipline members that violate the rules. All it can do is to reject loan requests of such countries which are leastly likely to ask for loans. There is no mechanism to settle disputes.
(iii) IMF's asset is puny. Also, international reserve assets of some countries far exceed the assets of the IMF.
|Only currencies of small countries should be pegged to major currencies such as dollar or a basket of currencies, but the currencies of major currencies should float vis-á-vis dollar.|
|Plaza Agreement||G-5 (Wester Germany, France, Japan, US and UK) stabilized Japanese yen in the mid 1980s. (Plaza Accord, 1985)|
|When the currency of a large country is undervalued, another currency is overvalued. Accordingly, it creates a problem similar to that when a government defends a weak currency.|
|In July 2005, China adopted a new policy, pegging Renminbi
to a basket of currencies (USD, euro, yen and won), but it is not freely
floating vis-à-vis other currencies.
As of December 2011, China's foreign exchange reserve surges to $3.18 trillion. Such intervention has resulted in a huge loss to China.
This is one reason for the US and EU to lower the interest rates.
|Once RMB is freely traded, there would be four major currencies in the foreign exchange markets: RMB, yen, euro and dollar.|
