The Second World War broke out a mere two decades after the end of the First World War. It was fought between the Axis powers (mainly Nazi Germany, Japan and Italy) and the Allies (Britain, France, the Soviet Union and the US). It was a war waged for six years on many fronts, in many places, over land, on sea, in the air. Once again death and destruction was enormous. At least 60 million people, or about 3 percent of the world’s 1939 population, are believed to have been killed, directly or indirectly, as a result of the war. Millions more were injured. Unlike in earlier wars, most of these deaths took place outside the battlefields. Many more civilians than soldiers died from war-related causes. Vast parts of Europe and Asia were devastated, and several cities were destroyed by aerial bombardment or relentless artillery attacks. The war caused an immense amount of economic devastation and social disruption. Reconstruction promised to be long and difficult.

Two crucial influences shaped post-war reconstruction. The first was the US’s emergence as the dominant economic, political and military power in the Western world. The second was the dominance of the Soviet Union. It had made huge sacrifices to defeat Nazi Germany, and transformed itself from a backward agricultural country into a world power during the very years when the capitalist world was trapped in the Great Depression.

Economists and politicians drew two key lessons from inter-war economic experiences. First, an industrial society based on mass production cannot be sustained without mass consumption. But to ensure mass consumption, there was a need for high and stable incomes. Incomes could not be stable if employment was unstable. Thus stable incomes also required steady, full employment. But markets alone could not guarantee full employment. Therefore governments would have to step in to minimise fluctuations of price, output and employment. Economic stability could be ensured only through the intervention of the government. The second lesson related to a country’s economic links with the outside world. The goal of full employment could only be achieved if governments had power to control flows of goods, capital and labour.

The Bretton Woods conference established the International Monetary Fund (IMF) to deal with external surpluses and deficits of its member nations. The International Bank for Reconstruction and Development (popularly known as the World Bank) was set up to finance post-war reconstruction. The IMF and the World Bank are referred to as the Bretton Woods institutions or sometimes the Bretton Woods twins. The post-war international economic system is also often described as the Bretton Woods system.

The Bretton Woods system inaugurated an era of unprecedented growth of trade and incomes for the Western industrial nations and Japan. World trade grew annually at over 8 percent between 1950 and 1970 and incomes at nearly 5 percent. The growth was also mostly stable, without large fluctuations. For much of this period the unemployment rate, for example, averaged less than 5 percent in most industrial countries.

When the Second World War ended, large parts of the world were still under European colonial rule. Over the next two decades most colonies in Asia and Africa emerged as free, independent nations. They were, however, overburdened by poverty and a lack of resources, and their economies and societies were handicapped by long periods of colonial rule. The IMF and the World Bank were designed to meet the financial needs of the industrial countries. They were not equipped to cope with the challenge of poverty and lack of development in the former colonies.

Despite years of stable and rapid growth, not all was well in this post-war world. From the 1960s the rising costs of its overseas involvements weakened the US’s finances and competitive strength. The US dollar now no longer commanded confidence as the world’s principal currency. It could not maintain its value in relation to gold. This eventually led to the collapse of the system of fixed exchange rates and the introduction of a system of floating exchange rates.
