I do believe it is important to have some knowledge of the market’s history, so this section covers the key points. If you have never studied global monetary systems, consider this section an abridged history of the forex market. The modern forex market’s roots began with over-the-counter currency trading desks established by banks throughout the 1970s and 1980s, following the collapse of a postwar-era monetary system known as the Bretton Woods system. Bretton Woods was established in June 1944, as World War II came to a close. The Allied nations sought to establish a new monetary system to promote global investment and capitalism and to eliminate the challenges of a gold standard system.
Under the Bretton Woods monetary system, member nations agreed to value their currency at parity to gold ±1 percent and then set their exchange rate against the U.S. dollar. In exchange, the United States agreed to peg the dollar against a gold standard of $35 per ounce and guarantee its exchange for gold. This promise by the U.S. government effectively made the dollar a global payment standard instead of using a gold standard. The phrase “good as gold” was frequently used to describe the U.S. dollar under the Bretton Woods monetary system. Although the system worked to foster investment and capitalism, it also encouraged a tremendous outflow of dollars into overseas currency reserves.
The world needed dollars to support a global payment system based on the dollar, and the United States was content printing more money. The United States assumed it could balance the deficit with trade. Unfortunately, the outflow of capital finally caught up to the Unites States in 1950 and the country began posting a negative balance of payments, despite the government’s best efforts to increase trade.
As inflationary concerns loomed on the horizon, the United States found itself in a difficult position. Failing to supply the global demand for dollars would bring the monetary system to its knees, whereas continuing to print money would eventually threaten to devalue the dollar. Confidence in the U.S. government’s ability to maintain a gold match standard for the dollar began to wane, and speculation grew that a serious devaluation in the world’s primary reserve currency was inevitable.
In August 1971, President Richard Nixon finally intervened by suspending the peg dollar had against gold. The Bretton Woods era of a fixed exchange rate system was over. Policy steps were taken to implement a floating exchange rate system, which is the cornerstone of today’s modern forex market. In the 1970s trading desks were established among major banking institutions to facilitate currency transactions for major clients. This private trading arrangement was known as the interbank, a term still used today to describe the electronic trading arrangements among major banks, institutions, and currency dealers. Today prices are determined by the forces of supply and demand within the forex market, allowing traders to capitalize on small swings between the exchange rates of two currencies.
