The Volcker squeeze: how 20% interest rates broke inflation
By the summer of 1979, Americans had lived with high inflation for most of a decade, and most expected it to continue. The new Fed chair, Paul Volcker, decided that only a shock to interest rates would change that belief. It worked, at the price of mortgage rates above 18% and the highest unemployment since the 1930s. Every central bank raising rates in 2026 is, in part, trying never to have to do it again.
Three years of rates near 20%
- Aug 1979Volcker takes overUS inflation is 11.5% and rising after the second oil shock. The federal funds rate is about 10.5%, below inflation, so money is effectively cheap.
- Oct 1979A change of methodOn 6 October the Fed announces it will target the growth of the money supply and let short-term rates go wherever that takes them. Rates jump.
- 1980A first, short recessionThe funds rate averages 17.6% in April 1980. The economy shrinks, rates are cut back to about 9% by July, and inflation, at 14.6% in March, starts to come down only slowly.
- 1981Back up, and held thereThe Fed tightens again: the funds rate averages 19.1% in January and June 1981. The 30-year mortgage rate reaches 18.4% in October.
- 1982–83The deep recession, then the breakUnemployment reaches 10.8% in December 1982. Inflation falls to 2.4% by July 1983, and stays low for decades.
Why it took such high rates
The problem was not just inflation but the belief that it would continue. Rates had to rise far enough, and stay high long enough, to change that belief.
With inflation at 11–14%, a 10% interest rate still meant cheap money. Only when rates were well above inflation did borrowing become genuinely costly and saving genuinely rewarding.
Mortgages above 15%, car loans and business credit at record costs cut spending and investment. Housing and manufacturing were hit hardest, and unemployment rose.
The decisive step was holding rates high in 1981–82 even as unemployment soared. Once workers and firms believed the Fed would not give in, wage and price demands fell, and inflation with them.
- Real interest rate
- An interest rate minus inflation. It shows what borrowing really costs once rising prices are taken into account.
- Inflation expectations
- How fast people, firms or investors think prices will rise in the future. Central banks watch them because wage demands and price setting follow them, so expectations that drift up can make high inflation last.
- Policy rate
- The short-term interest rate a central bank sets. It anchors what banks pay to borrow from each other overnight, and from there flows into loan and savings rates. Its name differs by country.
- Mortgage rate
- The interest rate charged on a loan to buy a home. Lenders set it from their own funding costs: the central bank's rate for variable loans, and market rates for fixed ones.
- Recession
- A broad fall in economic activity lasting more than a few months, with output, jobs and incomes all falling. A common rule of thumb is two quarters in a row of falling real GDP.
Painful, and decisive
The US had recessions in 1980 and 1981–82. High US rates and a strong dollar also helped trigger Latin America's debt crisis in 1982, when Mexico could no longer service its dollar loans.
The episode established the idea that an independent central bank must be willing to cause a downturn to keep inflation down, and that credibility makes the job cheaper. Inflation targets, adopted across the world from the 1990s, built on that lesson.
What assets did under Volcker
High rates crushed real asset prices at first, then set up one of the great bond and stock rallies.
| Asset | Period | Move | What happened |
|---|---|---|---|
| US shares | Aug 1979 → Jul 1982 | +3% | −22% after inflation. From July 1982 to August 1987 they rose 193% (+150% after inflation) as rates and inflation fell. |
| US 10-year yield | Aug 1979 → Sep 1981 | 9.03% → 15.32% | A record high. By December 1986 it was back to 7.11%: buyers at the peak locked in high yields as prices rose. |
| US dollar | Aug 1979 → Feb 1985 | +95% | High US rates drew money in from abroad. The surge led to the Plaza Accord of September 1985 to push it down. |
| Gold | Jan 1980 → 1982 | $850 → $376 | From the 21 January 1980 daily high to the 1982 annual average, as real interest rates turned sharply positive. |
Monthly averages unless stated; daily highs and lows were more extreme. "After inflation" deflates by US consumer prices. Past moves describe what happened then; they are not a guide to what will happen next.
Then and now: what rhymes
- An oil shock has pushed inflation up: 3.7% in the US, 4.0% in the euro area in autumn 2026.
- Central banks are raising rates even as growth slows: Australia, Sweden, the UK and the Czech Republic did so in one week in November.
- Policymakers talk about expectations and "second-round effects", Volcker's core concern.
What's different
Inflation is far lower than in 1979, and long-run expectations are still only a little above target (3.4% in the latest US survey). That is the point of acting early: today's rises are a quarter point at a time, not jumps to 20%. Central banks are trying to keep the 1970s from happening, rather than undoing them.
