The factors affecting XXX will affect both XXXYYY and XXXZZZ. This causes positive currency correlation between XXXYYY and XXXZZZ.

On the spot market, according to the BIS study, the most heavily traded products were:

* EURUSD: 27%
* USDJPY: 13%
* GBPUSD (also called cable): 12%

and the US currency was involved in 86.3% of transactions, followed by the euro (37.0%), the yen (17.0%), and sterling (15.0%) (see table). Volume percentages for all individual currencies should add up to 200%, as each transaction involves two currencies.

Trading in the euro has grown considerably since the currency’s creation in January 1999, and how long the foreign exchange market will remain dollar-centered is open to debate. Until recently, trading the euro versus a non-European currency ZZZ would have usually involved two trades: EURUSD and USDZZZ. The exception to this is EURJPY, which is an established traded currency pair in the interbank spot market. As the dollar’s value has eroded during 2008, interest in using the euro as reference currency for prices in commodities (such as oil), as well as a larger component of foreign reserves by banks, has increased dramatically. Transactions in the currencies of commodity-producing countries, such as AUD, NZD, CAD, have also increased.

The agreement made no provisions for international creation of reserves. New gold production was assumed to be sufficient. In the event of structural disequilibria, it was expected that there would be national solutions, for example, an adjustment in the value of the currency or an improvement by other means of a country’s competitive position. The IMF was left with few means, however, to encourage such national solutions.

It had been recognized in 1944 that the new system could only commence after a return to normalcy following the disruption of World War II. It was expected that after a brief transition period of no more than five years, the international economy would recover and the system would enter into operation.

To promote the growth of world trade and to finance the postwar reconstruction of Europe, the planners at Bretton Woods created another institution, the International Bank for Reconstruction and Development (IBRD), now the most important agency of the World Bank Group. The IBRD had an authorized capitalization of $10 billion and was expected to make loans of its own funds to underwrite private loans and to issue securities to raise new funds to make possible a speedy postwar recovery. The IBRD was to be a specialized agency of the United Nations charged with making loans for economic development purposes.
