The developed countries also agreed that the liberal international economic system required governmental intervention. In the aftermath of the Great Depression, public management of the economy had emerged as a primary activity of governments in the developed states. Employment, stability, and growth were now important subjects of public policy. In turn, the role of government in the national economy had become associated with the assumption by the state of the responsibility for assuring of its citizens a degree of economic well-being. The welfare state grew out of the Great Depression, which created a popular demand for governmental intervention in the economy, and out of the theoretical contributions of the Keynesian school of economics, which asserted the need for governmental intervention to maintain an adequate level of employment.

However, increased government intervention in domestic economy brought with it isolationist sentiment that had a profoundly negative effect on international economics. The priority of national goals, independent national action in the interwar period, and the failure to perceive that those national goals could not be realized without some form of international collaboration—which resulted in “beggar-thy-neighbor” policies such as high tariffs, competitive devaluations that contributed to the breakdown of the gold-based international monetary system, domestic political instability, and international war. The lesson learned was, as the principal architect of the Bretton Woods system New Dealer Harry Dexter White put it:

* the absence of a high degree of economic collaboration among the leading nations will…inevitably result in economic warfare that will be but the prelude and instigator of military warfare on an even vaster scale.

To ensure economic stability and political peace, states agreed to cooperate to closely regulate the production of their individual currencies to maintain fixed exchange rates between countries with the aim of more easily facilitating international trade. This was the foundation of the U.S. vision of postwar world free trade, which also involved lowering tariffs and among other things maintaining a balance of trade via fixed exchange rates that would be favorable to the capitalist system.

Thus, the more developed market economies agreed with the U.S. vision of post-war international economic management, which was to be designed to create and maintain an effective international monetary system and foster the reduction of barriers to trade and capital flows. In a sense, the new international monetary system was in fact a return to a system similar to the pre-war gold standard, only using US dollars as the world’s new reserve currency until the world’s gold supply could be reallocated via international trade. Thus, the new system would be devoid (initially) of governments meddling with their currency supply as they had during the years of economic turmoil preceding WWII. Instead, governments would closely police the production of their currencies and ensure that they would not artificially manipulate their price levels. If anything, Bretton Woods was in fact a return to a time devoid of increased governmental intervention in economies and currency systems.

A spot transaction is a two-day delivery transaction (except in the case of trades between the US Dollar, Canadian Dollar, Turkish Lira and Russian Ruble, which settle the next business day), as opposed to the futures contracts, which are usually three months. This trade represents a “direct exchange” between two currencies, has the shortest time frame, involves cash rather than a contract; and interest is not included in the agreed-upon transaction. The data for this study come from the spot market. Spot transactions has the second largest turnover by volume after Swap transactions among all FX transactions in the Global FX market.
