The Sterling System and the British Empire
The pound sterling was the principal international currency from the restoration of the gold standard in 1819 to the Bretton Woods conference of 1944. Through the second half of the nineteenth century, sterling accounted for perhaps 60 per cent of the world’s foreign-exchange reserves. This was not an accident of British wealth; it was the institutional expression of a system in which the City of London financed world trade by discounting bills drawn on the United Kingdom, the British Empire, and the wider periphery.
Susan Strange, in Sterling and British Policy: A Political Study of an International Currency in Decline (1971), treated the sterling system as a hierarchy in which the central position of London depended on the political subordination of an imperial periphery that held its reserves in sterling assets rather than gold. Charles Kindleberger, in A Financial History of Western Europe (1984), and Marcello de Cecco, in The International Gold Standard: Money and Empire (1984), placed the system in the longer history of the international gold standard and its successor regimes. The two readings — Strange on hierarchy, de Cecco on regime succession — together explain why sterling endured as long as it did, and why it eventually collapsed.
The Classical Gold Standard and Sterling, 1819–1914
The 1819 Resumption Act, passed under Lord Liverpool’s government, restored the convertibility of the Bank of England note into gold at the pre-1797 parity. Resumption was a deliberate act of statecraft: the British government bound itself to a deflationary adjustment in order to demonstrate to creditors that British obligations would be honoured in gold. The credibility of the commitment, as Barry Eichengreen argued in Golden Fetters: The Gold Standard and the Great Depression, 1914–1945 (1992), was the basis on which the City of London could finance the world.
Sterling was the principal reserve currency of the system, but it was not the only one. Germany, France, the United States, and the countries of the Latin Monetary Union all used gold. The British Empire’s contribution was the gold-exchange standard, in which India and the colonies held sterling assets (Indian council bills, consols) rather than gold as their reserves. The 1898 Herschell Committee, chaired by Lord Herschell, formalised this arrangement by pegging the rupee at 1s 4d sterling. The effect, as B. R. Tomlinson showed in The Political Economy of the Raj, 1914–1947 (1979), was to make the Indian peasant — through his taxes, paid in rupees and remitted to London as sterling — a substantial involuntary lender to the British Treasury.
The system worked because two conditions held. First, Britain’s industrial and financial primacy meant that the City of London could supply the world’s trade credit at lower cost than any rival. Second, the imperial preference system (see [/british-empire-economy/currency-and-finance/imperial-preference-trade/]) and the sterling-area system kept colonial reserves inside the British monetary system. As P. J. Cain and A. G. Hopkins argued in British Imperialism: 1688–2015 (2016), the relationship between “gentlemanly capitalism” in the City and the imperial periphery was the political foundation of the gold-standard system.
The 1914 Suspension and the 1925 Return
The First World War broke the gold standard. The Bank of England suspended convertibility on 1 August 1914, days after the Austrian ultimatum. The British government financed the war by issuing Treasury notes, by selling off foreign assets, and by running up debts with the United States. By 1918, the United States had replaced Britain as the world’s largest creditor.
The return to gold in 1925 at the pre-war parity of $4.86 was the decision of Winston Churchill, then Chancellor of the Exchequer. The decision was vigorously opposed by John Maynard Keynes, who argued in The Economic Consequences of Mr Churchill (1925) that the pre-war parity overstated the pound by perhaps 10 per cent and would impose a deflationary squeeze on British industry. The return to gold held, barely, for six years. The 1929 Wall Street crash, the 1930 collapse of the Credit Anstalt in Vienna, the 1931 failure of the Austrian and German banks, and the resulting wave of withdrawals from London produced a run on the pound. On 21 September 1931, the gold standard was suspended.
The sterling area emerged from the wreckage. By 1939 most of the British Empire, together with countries like Sweden, Denmark, Portugal, and Argentina that were not formally members of the Commonwealth, were holding their reserves in sterling and accepting exchange controls on capital movements. As de Cecco showed, the sterling area was a managed substitute for gold, with London playing the role that the Federal Reserve would later claim for New York. As Robert Skidelsky showed in his biography of Keynes (1983, 1992, 2000), the sterling area was also the institutional compromise between those who wanted to defend the gold standard and those who wanted to abandon it.
Bretton Woods, 1944, and the Dollar-Sterling Settlement
The Bretton Woods conference of July 1944 was the moment at which the dollar replaced sterling as the principal international reserve currency. The British delegation, led by Keynes, negotiated a system of fixed exchange rates anchored to a gold-convertible dollar; the Americans, led by Harry Dexter White, refused to accept Keynes’s plan for an international clearing union and insisted on a more hierarchical arrangement.
The Anglo-American loan agreement of December 1945 — $3.75 billion at 2 per cent over 50 years — was the price. As Charles Kindleberger showed in The World in Depression (1973) and A Financial History of Western Europe (1984), the loan was conditional on Britain’s acceptance of American-led multilateralism. The conditions included the convertibility of sterling for current-account transactions, the dismantling of imperial preference (see [/british-empire-economy/currency-and-finance/imperial-preference-trade/]), and the opening of the British market to American goods. Britain accepted. The 1947 General Agreement on Tariffs and Trade, signed in Geneva on 30 October, formally tied Britain to the multilateral system.
The Decolonisation of Sterling, 1947–1979
The post-1945 sterling area was an instrument of managed retreat. The 1949 devaluation from $4.03 to $2.80, the 1957 sterling crisis produced by Suez and by the over-valuation of the pound, the 1967 devaluation to $2.40, and the 1972 closure of the gold pool were the visible markers. The underlying process was the decolonisation of the sterling balances — the sterling assets held by the colonies and former colonies — that had built up during the war. By 1971, the sterling area had effectively dissolved; the British government ceased to defend the parity of overseas sterling in 1972.
The 1979 creation of the European Monetary System, with the Exchange Rate Mechanism at its centre, was an attempt to anchor sterling to a new system. The 1990 decision to join the ERM at DM2.95 produced, in turn, the September 1992 sterling crisis. The Bank of England, under Robin Leigh-Pemberton, was forced to withdraw from the ERM after a single day of intervention. Sterling has floated freely since.
The legacy is institutional. The Reserve Bank of India (1935), the Reserve Bank of Australia (1960), the South African Reserve Bank (1921), the Bank of Canada (1934), the Bank of Ghana (1957), the Central Bank of Nigeria (1958), and the central banks of Kenya, Tanzania, Uganda, Jamaica, and dozens of other former colonies were all modelled, in their founding charters, on the Bank of England. As Geoffrey Wood argued in The Anatomy of Central Banking (2013), the post-imperial central banking system is a direct descendant of the sterling system.
A Primary Source: Keynes at Bretton Woods
Keynes’s opening address to the Bretton Woods conference on 1 July 1944, lamenting the failure to construct a true international clearing union, declared: “I find myself in the position, after long and anxious discussions in Washington, of being largely in agreement with the plan of the United States. … But the question is whether we shall succeed in establishing a system which is stable. … I am deeply fearful of the conditions of the immediate post-war world, and I am therefore led to hope that the conference will achieve a settlement which will be durable.” The settlement was durable, but it was not the one Keynes had hoped for.
Historiographical Note
The historiography of the sterling system has been shaped by the political economy of British decline. Strange, in Sterling and British Policy (1971), treated the sterling area as a managed hierarchy that allowed the British to delay the consequences of relative economic decline. Eichengreen and de Cecco have placed the sterling system in the longer history of the international gold standard. Skidelsky and Cain & Hopkins have emphasised the political logic of the system: the imperial preference and sterling area structures were not free choices but the institutional expressions of British interests. The unresolved question is whether the sterling system was, on balance, an instrument of stability or of delayed crisis; the consensus, as Branko Milanovic has argued in Capitalism, Alone (2019), is that the answer depends on the political standpoint chosen.
