The 1973-75 Recession: Oil Crisis, Stagflation, and the End of Bretton Woods

The 1973-75 recession was the postwar US economy's first encounter with stagflation, a combination of high inflation and rising unemployment that orthodox Keynesian models had implied was theoretically impossible. The cycle ran 16 months from November 1973 to March 1975 by NBER's subsequent dating, contracted real GDP by 3.2 percent peak to trough, and pushed unemployment to 9.0 percent in May 1975, the highest postwar reading until that point. Consumer price inflation simultaneously reached 12.3 percent in 1974, breaking the previously assumed inverse relationship between inflation and unemployment.

The proximate trigger was the October 1973 OPEC oil embargo, which quadrupled crude oil prices in three months. But the underlying conditions had been building for years. The collapse of the Bretton Woods exchange-rate system in August 1971 had removed a key external discipline on US monetary policy. Nixon-era wage and price controls had suppressed measured inflation while distorting relative prices and creating a backlog of pent-up price pressure. Accommodative monetary policy through the late 1960s and early 1970s had embedded inflation expectations that the supply shock then amplified into the first stagflation.

Origins: The End of Bretton Woods

The Bretton Woods exchange-rate system, established at the 1944 conference in New Hampshire, fixed the US dollar to gold at $35 per ounce and required participating nations to maintain their currencies within narrow bands around dollar parities. The system rested on the assumption that the United States would manage its monetary policy responsibly enough that other nations would not need to convert dollar holdings to gold. By the late 1960s, that assumption was straining: US gold reserves had fallen from $24 billion in 1949 to $11 billion by 1971 as foreign central banks converted dollars in response to inflation concerns about US monetary policy.

On Sunday 15 August 1971, President Nixon announced a comprehensive economic programme: suspension of dollar convertibility into gold, a 10 percent surcharge on imports, and a 90-day freeze on wages and prices. The Bretton Woods action effectively ended the postwar exchange-rate system. The dollar then floated and depreciated approximately 20 percent against the German mark and Japanese yen by 1973. The depreciation contributed to inflation by raising import prices and removed the external monetary discipline that had constrained US policy under fixed exchange rates.

The Yom Kippur War and the OPEC Embargo

On 6 October 1973, Egyptian and Syrian forces attacked Israel on the Yom Kippur holiday, beginning a 19-day war. The United States, Netherlands, and other Western nations supplied military equipment to Israel during the conflict. On 17 October 1973, the Organisation of Arab Petroleum Exporting Countries announced an oil embargo against those nations. Within OPEC more broadly, posted oil prices were raised unilaterally from approximately $3 per barrel to $5.12 in October, then to $11.65 by January 1974, a near four-fold increase.

The supply shock propagated rapidly through the US economy. Gasoline prices rose from 36 cents per gallon in mid-1973 to over 50 cents by mid-1974. Several states adopted odd-even gasoline rationing systems based on licence plate numbers. Filling stations posted hours-long queues. Energy-intensive industries (autos, chemicals, plastics, freight trucking, aviation) faced sharp cost increases that they could not fully pass through to customers. Real consumer spending fell as households absorbed energy-price increases, and business capital expenditure pulled back as firms reassessed energy-intensive investments.

Stagflation Arrives

The simultaneous occurrence of high inflation and high unemployment was previously thought theoretically impossible by mainstream Keynesian economic models. The Phillips curve, formalised in 1958 from UK data, implied an inverse relationship between inflation and unemployment: tight labour markets produced wage and price pressure, slack labour markets produced disinflation. Postwar US data through the 1960s broadly confirmed the relationship.

The 1973-75 cycle definitively broke that assumption. Consumer price inflation reached 12.3 percent in 1974 while unemployment rose from 4.9 percent to 7.2 percent over the same year. By May 1975, unemployment peaked at 9.0 percent while inflation was still running at 9 percent annualised. The breakdown of the Phillips relationship had several theoretical explanations that economists subsequently developed. Milton Friedman's 1968 expectations-augmented Phillips curve had predicted that workers would adjust wage demands to expected future inflation, making the short-run inflation-unemployment trade-off temporary. The 1970s data validated his model and contributed to the rise of monetarist and rational-expectations approaches to macroeconomic policy.

The Policy Response and Its Limits

The Federal Reserve under Chairman Arthur Burns faced an impossible choice. Tightening monetary policy to fight inflation would deepen the unemployment problem. Easing to support employment would entrench inflation expectations. The Fed pursued a stop-go policy: tightening as inflation rose, easing as unemployment rose, never sustaining either approach long enough to be effective. The federal funds rate moved between 5 and 13 percent during the cycle without breaking inflation expectations.

Fiscal policy was constrained by the macroeconomic confusion. The Ford administration introduced the WIN (Whip Inflation Now) campaign in October 1974, encouraging voluntary household spending restraint and energy conservation. The campaign was widely mocked at the time and had no measurable economic impact. The 1975 Tax Reduction Act provided a one-time tax rebate that supported short-term consumption but did not address the underlying inflation-expectations problem.

The Slow Recovery and the Second Oil Shock

NBER dated the recession trough to March 1975, and recovery began. Real GDP grew 5.4 percent in 1976 and 4.6 percent in 1977. Unemployment fell from its 9.0 percent peak to 6.0 percent by mid-1978. But inflation remained above 5 percent throughout the recovery, and inflation expectations had not been broken. The Federal Reserve continued its stop-go pattern under Chairmen Burns and G William Miller.

In July 1979, the Iranian Revolution disrupted crude oil supply for the second time in six years. Oil prices rose from $15 per barrel to over $35 per barrel by 1980, setting up the next inflation surge. The accumulated inflation expectations from the 1970s ultimately required the deeply painful 1981-82 Volcker recession to break. The 1973-75 cycle was the first stage of a 9-year period of elevated inflation and unemployment that did not fully resolve until the 1983-84 recovery.

Long-Term Consequences

The 1973-75 recession permanently changed the relationship between the US economy and energy. Corporate Average Fuel Economy standards adopted in 1975 required automakers to double passenger-car fuel economy by 1985. Building insulation programmes, industrial process redesigns, and the expansion of nuclear power and coal use reduced US energy intensity per unit of GDP by approximately 50 percent over the subsequent twenty years. Strategic Petroleum Reserves were established in 1975 to buffer against future supply shocks. The Alaska pipeline reached completion in 1977. By the early 1980s, US oil consumption was substantially below its 1973 peak even as the economy continued to grow.

The macroeconomic policy framework shifted toward greater central bank independence and explicit inflation focus, ultimately producing the Volcker tightening of 1979-82 and the four-decade era of low inflation that followed. The political consequences included the decline of the Keynesian-influenced postwar consensus on economic management and the rise of the Reagan-era free-market policy framework. The cultural memory of stagflation, the energy crisis, gasoline lines, and Carter-era economic malaise shaped US politics for two decades.

The 1973-75 cycle also reshaped the academic discipline of macroeconomics. The breakdown of the Phillips curve relationship between inflation and unemployment, which had been the central organising framework of postwar Keynesian macroeconomic policy, forced theoretical reassessment. The expectations-augmented Phillips curve developed by Milton Friedman in 1968 had predicted exactly the breakdown that the 1970s data confirmed. Robert Lucas' rational-expectations critique, formalised in the early 1970s, argued that the Phillips relationship would shift as soon as policymakers attempted to exploit it. The 1973-75 stagflation provided the empirical validation that pushed both theories from minority positions in the late 1960s to central organising frameworks of macroeconomics by the early 1980s. Modern macroeconomic policy frameworks (inflation targeting, central bank independence, forward guidance) all trace at least partial intellectual lineage to the lessons drawn from 1973-75.

The cycle is also a useful comparative case for the 2021-23 inflation episode. Both episodes involved supply shocks (oil in 1973, COVID supply disruptions in 2021) combined with accommodative monetary policy that allowed inflation to spread from supply-driven to demand-driven dynamics. The 2021-23 episode resolved more quickly than the 1970s case partly because the Federal Reserve under Jerome Powell explicitly invoked the Volcker-era lessons in committing to sustained tightening, partly because the underlying supply disruptions of 2021 (port congestion, semiconductor shortages, energy supply) resolved faster than the structural energy reallocation of the 1970s, and partly because inflation expectations had not become as entrenched in the 2021-23 episode as in the 1970s. The faster 2021-23 resolution should not be assumed inevitable; the 1970s parallel remains a cautionary case for the long-run cost of allowing supply-shock-driven inflation to embed in expectations.
