Stagflation: The 1970s Oil Shocks and What They Teach Today

What stagflation means

The Federal Reserve History essay on the Great Inflation uses "stagflation" for an era when inflation and unemployment were both unacceptably high. Its numbers show the shift. In 1964, inflation was a little over 1% a year and unemployment about 5%. In 1974, inflation was over 12% and unemployment above 7%. The essay calls the period from 1965 to 1982 "the defining macroeconomic event of the second half of the twentieth century" and notes that it included four recessions, two energy shortages and peacetime wage and price controls.

The timeline

Sources: Federal Reserve History essays (Oil Shock of 1973–74, Oil Shock of 1978–79, The Great Inflation, Recession of 1981–82); NBER business-cycle dates. Oil rose from $2.90 to $11.65, which is 4.0 times, or about +302% (our calculation); the Fed essay describes it as nearly quadrupling.

Shock one: 1973–74

The embargo began on 19 October 1973, right after Nixon asked Congress for $2.2 billion in emergency aid for Israel. It ended in March 1974, but the higher prices remained. The Fed's essay stresses that inflation was already building: in mid-1973, wholesale prices of industrial commodities were rising at more than 10% a year.

Shock two: 1978–79

The Iranian revolution cut Iranian output sharply by January 1979, and oil prices began rising rapidly in mid-1979. The Fed essay says prices more than doubled between April 1979 and April 1980, and suggests the disruption "may have prompted a fear of further disruptions and spurred widespread speculative hoarding." (The Great Inflation essay says the revolution "tripled" the cost of oil, so treat the exact multiple as approximate.) The essay dates rationing in nine California counties to 9 May 1979. Twelve-month CPI inflation reached 9% by the end of 1979 and peaked near 15% in 1980.

Oil was not the only cause

The Fed's essays are blunt on this. The 1973 oil shock was one of many factors creating "a perfect economic storm." Arthur Burns's own 1979 list of causes included financing of the Vietnam War, dollar devaluations in 1971 and 1973, the 1972–73 global boom, 1974–75 crop failures and a sharp productivity slowdown. The Great Inflation essay goes further: there is little debate that the source of the inflation was Fed policy, which "allowed for an excessive growth in the supply of money." Other causes it names:

The Fed essay says the 1973 shock "came at a most inopportune time for the United States."

• The Phillips curve belief. Policymakers thought lower unemployment could be bought with modestly higher inflation. Phelps and Friedman warned that the curve would shift upward as people came to expect inflation, and the essay says the trade-off became less favourable as businesses and households anticipated rising prices.
• Bad real-time data. Orphanides found that real-time estimates overstated potential output and understated the unemployment rate consistent with full employment.
• Price controls. Nixon's controls only temporarily slowed prices and worsened shortages.
• Policy attitudes toward cost-push inflation. A 1971 view quoted in the essay held that continuing cost increases were "a structural problem not amenable to macro-economic measures."

An economists' debate: could policy have blunted the oil shocks?

Bernanke, Gertler and Watson (1997) argued that much of the recessionary effect attributed to oil shocks came from how monetary policy responded. James Hamilton and Ana Maria Herrera replied in a paper dated June 2000 (revised July 2001). They argued that "even the aggressive Federal Reserve policies proposed would not have succeeded in averting a downturn," and that using longer lags in the model roughly doubles the estimated oil effects, with the strongest impact three to four quarters after a shock. Their baseline: a 10% rise in oil prices means 0.25% slower real GDP growth and 0.2% higher prices after two years. On 1973–74 they write that the simulation "predicts a modest downturn in GDP growth, though most of the recession of 1974–75 would seem to require other explanations."

The Fed's own essay on the 1973 shock cites Bernanke (2004): "monetary policy cannot offset the recessionary and inflationary effects of increased oil prices." The debate is not settled in a sentence. What both sides accept is that policy and oil interacted.

How it ended, and what it cost

Volcker was appointed in August 1979 and, in October, the FOMC shifted to targeting reserve growth. He raised the funds rate from 11% to a peak close to 20% in 1980–81 (the Fed essays give 19% in one place and "approach 20 percent" in another). The Fed's account of the 1981–82 recession says it was "triggered by tight monetary policy in an effort to fight mounting inflation." Unemployment was about 7.4% at the start of the recession, nearly 10% a year later, and nearly 11% at the end of 1982. By October 1982 inflation had fallen to 5%, and the Fed let the funds rate fall to 9%. The essay credits Volcker's persistence: "Ultimately, this persistence paid off." The Great Inflation essay adds that expectations and policy credibility became central to macroeconomic models afterward.

The Oil Shock of 1978–79 essay describes the combination of monetary contraction and oil shock as the most severe recession since the Great Depression. The cost of ending the inflation was therefore a deep recession, not a painless adjustment.

What the 1970s do and do not say about today

Energy prices are rising again in 2026, so the comparison is natural. The facts, as published:

Set against the 1974 profile (inflation over 12%, unemployment above 7%), the 2026 readings are far milder, and nothing in the data above amounts to stagflation in the 1970s sense. Weak payroll growth with an energy shock is worth watching, but it is a different starting point. Three differences are worth keeping in mind, with caveats:

• Oil. The EIA's September 2026 outlook says the Brent crude price averaged $91 a barrel in August, $7 higher than July, because exports out of the Middle East remained constrained through the Strait of Hormuz. The EIA forecasts about $90 for the second half of 2026 and a gradual fall to $74 in 2027. It also states that its inputs were finalized on 3 September 2026.
• Inflation. In the BLS release for August 2026, energy rose 16.3% over twelve months; the all-items CPI rose 3.4%, and core (excluding food and energy) 2.4%. Core PCE was 3.0% according to BEA's release.
• Jobs. In September 2026 the unemployment rate was 4.2% and nonfarm payrolls rose by 29,000, with July and August revised down by a combined 60,000.

1. Starting inflation and expectations. The 1970s shocks hit an economy where inflation was already rising. Whether expectations are anchored today is something to check in current surveys, which this article does not cover.
2. Energy intensity. Fernald and Trehan of the San Francisco Fed wrote in 2005 that oil-price effects "are likely to have been larger in the 1970s, when the economy was more energy-intensive." That was a 2005 observation, and we have not rechecked it against current data.
3. The source of the shock. In 2005, the same authors argued that a price rise driven by stronger global demand is less worrying than a supply disruption. The 2026 rise, per the EIA, comes from constrained Middle East exports, which is a supply story. In our reading, that makes the comparison with 1973 and 1979 closer than the 2005 one, though the sources do not draw that comparison.

Lessons

This article is general information, not financial advice.

1. Shocks land on starting conditions. Mid-1973 wholesale industrial prices were already rising above 10% a year before the embargo.
2. Expectations matter. The Fed's history says expectations and policy credibility became central to macroeconomic models afterward.
3. Do not read one data series as a regime. One energy spike plus soft payrolls is not stagflation. Both inflation and unemployment have to stay high.
4. Fighting inflation has a price. The 1981–82 recession is the Fed's own example.
