There's a historical analogy that's giving economists and investors some serious déjà vu—and not the good kind. It's the kind that keeps you up at night wondering if we're about to relive one of the most painful economic chapters in modern history.

The 1970s didn't have one inflation wave. It had two.

The first peaked in 1974 and then faded. Policymakers declared victory a bit too enthusiastically. Then the Iranian Revolution of 1979 yanked millions of barrels a day from global markets, oil prices doubled, and CPI surged to nearly 13%. It took Paul Volcker, 20% interest rates, and a brutal recession to finally put that fire out.

Fast forward fifty years. The pandemic and Russia's invasion of Ukraine in February 2022 drove the first inflationary surge of the 2020s, pushing CPI to 9.1% in June 2022—the highest since 1981. Then came three years of aggressive Fed tightening, falling energy prices, and a hard-won disinflation that brought inflation back to 2.4% by January 2026.

The Fed had begun cutting rates. The fight, to all appearances, was won.

With oil prices now back to triple digits, the 2020s could be tracing the same ominous shape—and the country potentially triggering the second shock is, once again, Iran.

Inflation Today Vs. 1970s: The Chart That's Keeping Economists Up at Night

The narrative of the 1970s as a single inflation event is misleading. It was two structurally distinct shocks, separated by a period of incomplete recovery that policymakers mistook for resolution.

The first shock arrived in October 1973. After the Yom Kippur War, Arab OPEC members cut oil exports to nations that had supported Israel. The embargo was partly political theater—the actual supply reduction was more modest than the price reaction—but it was enough to trigger panic buying and a quadrupling of oil prices from roughly $3 to nearly $12 a barrel within months. U.S. CPI, already rising on the back of Vietnam War-era deficit spending and the collapse of the Bretton Woods dollar peg, peaked above 12% in late 1974.

The Federal Reserve, under Chairman Arthur Burns, interpreted the decline as a victory and pivoted to a looser monetary policy. The underlying inflationary pressure—loose monetary conditions, unanchored expectations, structural energy dependence—was never fully cleared.

The second shock came from Iran. The Islamic Revolution of 1978–1979 collapsed Iranian production by roughly 4.8 million barrels per day. The Iran-Iraq War, which began in September 1980, removed both countries' output simultaneously. Oil prices more than doubled in a year. Because inflation had never been extinguished, the second shock detonated inside an already-primed system. CPI surged to nearly 13% by 1980.

Ending the second wave required Fed Chairman Paul Volcker—appointed by President Jimmy Carter in August 1979 with an explicit mandate to break inflation—and interest rates that touched 20%. Unemployment peaked above 10%. The recession of 1981–1982 was one of the deepest since World War II.

The 2020s Are Running the Same Playbook

The parallels are precise enough to be uncomfortable. The first inflationary surge of the 2020s was partly demand-driven—the result of an unprecedented pandemic-era monetary and fiscal expansion—and partly supply-driven, detonated by Russia's invasion of Ukraine on February 24, 2022. Oil prices surged above $100 a barrel within days. U.S. CPI peaked at 9.1% in June 2022.

What followed looked like a successful managed landing. The Fed raised rates from near-zero to 5.25–5.50%. Energy prices fell as global demand softened and Russia redirected crude to non-Western buyers. By January 2026, CPI had slowed to 2.4%. The Fed had already cut rates by 175 basis points from the 2022 peak. Markets priced further easing and economists declared the inflation fight over.

Then came February 28, 2026.

Oil Prices Back Above $100 — What It Does to Inflation Math

Goldman Sachs, which had forecast inflation ending 2026 at 2%—right at the Fed's target—warned clients that if oil price gains persist, CPI could climb to 3% by year-end.

Morgan Stanley estimates that a 10% rise in oil prices from a supply shock adds roughly 0.35 percentage points to U.S. headline CPI within three months. With WTI crude – as tracked by the United States Oil Fund United States Oil Fund (USO) – having rallied from approximately $72.50 before the war to above $100—a rise of nearly 38%—the direct mechanical pass-through implies over a full percentage point of additional CPI pressure, before secondary effects in food, goods transport, and services are counted.

Meanwhile, prediction markets are rapidly repricing inflation risks. Prior to the first U.S. strike on Iran, Polymarket contracts implied about a 30% chance that annual inflation in 2026 would exceed 3%. That probability has now jumped to 94%.

When Victory Is Declared Too Soon

The Fed now faces the same trap Burns fell into in 1979: an oil shock arriving before inflation expectations were fully re-anchored, a weakening labor market pulling in the opposite direction, and a leadership transition adding further uncertainty.

Fed Chair Jerome Powell's term ends in two months. His likely successor, Kevin Warsh—President Donald Trump's nominee for the role—has advocated lower interest rates, a stance now on a collision course with an oil shock that economists warn could force the Fed to keep rates on hold, if not raise them.

The symmetry is almost too clean to be a coincidence. The only open question now is the one Volcker answered at the cost of a recession: how much pain does it take to end it the second time?
