Explain the end of the long boom in the 1970s, including the collapse of Bretton Woods and the oil crises, and assess their impact on the global economy

What this dot point is asking

SEAB wants you to explain why the long postwar boom ended in the 1970s, focusing on the collapse of the Bretton Woods system of fixed exchange rates and the oil crises, and to assess their impact on the global economy. The central analytical task is to distinguish the trigger from the underlying strains: the oil shocks delivered a sharp blow, but the boom was already slowing and the monetary order was already breaking down. A strong answer judges how far the oil crises caused the end and traces the consequences for economic policy.

The answer

The breakdown of Bretton Woods

The first major rupture was monetary. The Bretton Woods system depended on confidence in the United States dollar and on the dollar's convertibility to gold at a fixed price. As American spending and deficits grew, more dollars circulated abroad than could be backed by gold, and confidence eroded. At the start of the 1970s the United States ended the dollar's convertibility to gold, which effectively destroyed the system of fixed exchange rates. The world moved to a regime of floating exchange rates, in which currency values were set by markets rather than fixed by agreement. The stable monetary anchor that had underpinned the boom was gone, introducing new volatility into the global economy.

The oil crises

The second and more dramatic rupture came from energy. The long boom had been fuelled by cheap and abundant oil. In the 1970s, oil-exporting states, acting together, sharply raised prices, and a further steep rise followed later in the decade. Because oil was an essential input across the entire industrial economy, these sudden price rises raised costs everywhere at once. The oil crises transferred enormous wealth to oil-exporting states and inflicted a severe shock on the oil-importing industrial economies, ending the era of cheap energy that had powered postwar growth.

Stagflation: a new economic problem

The combination of these shocks with the fading momentum of the boom produced an unfamiliar and troubling condition: stagflation, the simultaneous occurrence of high inflation and economic stagnation with rising unemployment. This combination confounded the prevailing economic orthodoxy, which had assumed that inflation and unemployment moved in opposite directions, so that a government could trade a little more of one for less of the other. Stagflation meant that the standard tools no longer worked as expected, and it discredited the postwar consensus on economic management. The 1970s were therefore a decade not just of slower growth but of intellectual crisis in economic policy.

The underlying strains

A strong answer recognises that the boom was already losing momentum before the oil shocks struck. The drivers of the golden age, postwar reconstruction, the catching-up of economies adopting existing best practice, and the easy gains from cheap energy and rapid trade expansion, were naturally fading as economies matured and reconstruction was completed. Productivity growth was slowing. The collapse of Bretton Woods had already removed the monetary anchor. The oil crises therefore struck an economy that was already slowing and a monetary order that had already broken down; they gave the downturn its severity and its inflationary character but did not create the underlying slowdown.

The impact on the global economy

The end of the long boom reshaped the global economy and its governing ideas. The discrediting of the postwar consensus opened the way for a shift toward more market-oriented policies in the following decade, with greater emphasis on controlling inflation, deregulation, and a reduced role for the state. The transfer of wealth to oil-exporting states redirected global financial flows. Floating exchange rates and freer capital movement laid some of the groundwork for the financial globalisation that followed. The 1970s thus mark a turning point between the managed, stable order of the golden age and the more liberalised, volatile global economy of the later century.

Examples in context

Example 1. Stagflation and the crisis of orthodoxy. The appearance of stagflation in the 1970s is the clearest sign that the crisis was more than a downturn. The prevailing economic orthodoxy had assumed that inflation and unemployment moved in opposite directions, so the simultaneous rise of both confounded policymakers and discredited the postwar consensus. This intellectual failure is what opened the way to the market-oriented policies of the following decade, making the 1970s a turning point in economic thinking as well as in growth.

Example 2. The shift to floating exchange rates. The end of the dollar's convertibility to gold and the move to floating exchange rates is the monetary heart of the 1970s rupture. It removed the stable anchor that had underpinned the long boom and introduced a new volatility into international finance. Over time, floating currencies and freer capital movement helped lay the groundwork for the financial globalisation of the later century, linking the breakdown of the 1970s to the more integrated global economy that followed.

Q1. Define stagflation. [4 marks]

• Cue. The simultaneous occurrence of high inflation and economic stagnation with rising unemployment, a combination that confounded the postwar economic orthodoxy.

Q2. Explain why the Bretton Woods system collapsed. [12 marks]

• Cue. Growing American deficits put more dollars abroad than could be backed by gold, eroding confidence; the United States ended dollar-gold convertibility, destroying fixed exchange rates and ushering in floating currencies.

Q3. "The 1970s were a turning point in the global economy." How far do you agree? [20 marks]

• Cue. Argue that the twin ruptures and stagflation ended the golden age and discredited the postwar consensus, opening the way to market-oriented, liberalised policies; weigh continuities; judge.
