The sterling area (or sterling bloc, legally scheduled territories) was a group of countries that either pegged their currencies to sterling, or actually used sterling as their own currency. The area began to appear informally during the early 1930s, after sterling had left the gold standard in 1931, with the result that a number of currencies of countries that historically had performed a large amount of their trade in sterling were pegged to sterling instead of to gold. A large number of these countries were part of the British Empire; however, a significant minority were not. Early in the Second World War, emergency legislation united the sterling bloc countries and territories (except Hong Kong) of the British Empire in a single exchange control area to protect the external value of sterling, among other aims. Canada and Newfoundland were already linked to the US dollar and did not join the sterling bloc. The Bank of England in London guided co-ordination of monetary policy in the currency area. Member countries with their own currency held a large portion of their foreign currency reserves as sterling balances in London. After the Second World War, the Bretton Woods system of fixed exchange rates to the US dollar (convertible to gold) gave the sterling area a second lease of life as Commonwealth of Nations kinship and trading loyalties were maintained after Britain's withdrawal from Empire by keeping a sterling peg and staying in the sterling area, rather than maintaining a direct dollar peg. Despite this, sterling did not regain anything like its place in international commerce that it had had before the war, and a devastated and financially exhausted Britain could not defend the international value of sterling to maintain confidence in the system, resulting in its devaluation of the pound sterling against the dollar in 1967 that was not reflected in other sterling area currencies. In the end the US dollar's inability to hold to the Bretton Woods gold standard precipitated the end of the era of fixed exchange rates: with all major currencies including the pound floating against the US dollar, the sterling area had lost its final raison d'être. In June 1972, the British government unilaterally applied exchange controls to the other sterling area countries, with the exception of Ireland, the Isle of Man and the Channel Islands. This arguably marked the end of the sterling area. During the rest of the
