Bretton Woods system

The Bretton Woods system of monetary management established the rules for commercial relations among 44 countries, including the United States, Canada, Western European countries, and Australia, after the 1944 Bretton Woods Agreement until the Jamaica Accords in 1976. The Bretton Woods system was the first example of a fully negotiated monetary order intended to govern monetary relations among independent states. The Bretton Woods system required countries to guarantee convertibility of their currencies into U.S. dollars to within 1% of fixed parity rates, with the dollar convertible to gold bullion for foreign governments and central banks at US$35 per troy ounce of fine gold (or 0.88867 gram fine gold per dollar). It also envisioned greater cooperation among countries in order to prevent future competitive devaluations, and thus established the International Monetary Fund (IMF) to monitor exchange rates and lend reserve currencies to countries with balance of payments deficits.

Preparing to rebuild the international economic system while World War II was still being fought, 730 delegates from all 44 Allied countries gathered at the Mount Washington Hotel in Bretton Woods, New Hampshire, United States, for the United Nations Monetary and Financial Conference, also known as the Bretton Woods Conference. The delegates deliberated from 1 to 22 July 1944, and signed the Bretton Woods agreement on its final day. Setting up a system of rules, institutions, and procedures to regulate the international monetary system, these accords established the IMF and the International Bank for Reconstruction and Development (IBRD), which today is part of the World Bank Group. The United States, which controlled two-thirds of the world's gold, insisted that the Bretton Woods system rest on both gold and the US dollar. Soviet representatives attended the conference but later declined to ratify the final agreements, charging that the institutions they had created were "branches of Wall Street". These organizations became operational in 1945 after a sufficient number of countries had ratified the agreement. According to Barry Eichengreen, the Bretton Woods system operated successfully due to three factors: "low international capital mobility, tight financial regulation, and the dominant economic and financial position of the United States and the dollar."

Eurodollar growth increased capital flows, challenging regulation of capital movements. On 15 August 1971, the United States ended the convertibility of the US dollar to gold, effectively bringing the Bretton Woods system to an end and rendering the dollar a fiat currency. Shortly thereafter, many fixed currencies (such as the pound sterling) also became free-floating, and the subsequent era has been characterized by floating exchange rates. The end of Bretton Woods was formally ratified by the Jamaica Accords in 1976.

The planners at Bretton Woods hoped to avoid a repetition of the Treaty of Versailles after World War I, which had created enough economic and political tension to lead to WWII. After World War I, Britain owed the U.S. substantial sums, which Britain could not repay because it had used the funds to support allies such as France during the War; the Allies could not pay back Britain, so Britain could not pay back the U.S. The solution at Versailles for the French, British, and Americans seemed to entail ultimately charging Germany for the debts. If the demands on Germany were unrealistic, then it was unrealistic for France to pay back Britain, and for Britain to pay back the US. Thus, many "assets" on bank balance sheets internationally were actually unrecoverable loans, which culminated in the 1931 banking crisis. Intransigent insistence by creditor countries for the repayment of Allied war debts and reparations, combined with an inclination to isolationism, led to a breakdown of the international financial system and a worldwide economic depression.

The beggar thy neighbour policies that emerged as the crisis continued saw some trading countries using currency devaluations in an attempt to increase their competitiveness (i.e. raise exports and lower imports), though recent research^[when?] suggests this de facto inflationary policy probably offset some of the contractionary forces in world price levels (see Eichengreen "How to Prevent a Currency war").

In the 1920s, international flows of speculative financial capital increased, leading to extremes in balance of payments situations in various European countries and the US. In the 1930s, world markets never broke through the barriers and restrictions on international trade and investment volume – barriers haphazardly constructed, nationally motivated and imposed. The various anarchic and often autarkic protectionist and neo-mercantilist national policies – often mutually inconsistent – that emerged over the first half of the decade worked inconsistently and self-defeatingly to promote national import substitution, increase national exports, divert foreign investment and trade flows, and even prevent certain categories of cross-border trade and investment outright. Global central bankers attempted to manage the situation by meeting with each other, but their understanding of the situation as well as difficulties in communicating internationally, hindered their abilities. The lesson was that simply having responsible, hard-working central bankers was not enough.

Britain in the 1930s had an exclusionary trade bloc with countries and territories of the British Empire known as the Sterling Area. If Britain imported more than it exported to such trading partners, recipients of pounds sterling within these countries tended to put them into London banks. This meant that though Britain was running a trade deficit, it had a financial account surplus, and payments balanced. Increasingly, Britain's positive balance of payments required keeping the wealth from across its Empire in British banks. One incentive for, say, South African holders of rand to park their wealth in London and to keep the money in Sterling, was a strongly valued pound sterling. In the 1920s, imports from the US threatened certain parts of the British domestic market for manufactured goods and the way out of the trade deficit was to devalue the currency. But Britain could not devalue, or the Empire surplus would leave its banking system.

Nazi Germany also worked with a bloc of controlled countries by 1940. Germany forced trading partners with a surplus to spend that surplus importing products from Germany. Thus, Britain survived by keeping Sterling-using countries' surpluses in its banking system, and Germany survived by forcing trading partners to purchase its own products. The U.S. was concerned that a sudden drop-off in war spending might return its population to the unemployment levels of the 1930s, and so wanted Sterling-using countries and everyone in Europe to be able to import from the US, hence the U.S. supported free trade and international convertibility of currencies into gold or dollars.
