Stagflation is the simultaneous occurrence of stagnant economic growth, high inflation, and high unemployment. The term blends “stagnation” and “inflation.” It defies conventional economic thinking because standard models suggest inflation falls when unemployment rises — stagflation breaks that relationship.

The textbook example: the US in the 1970s, when oil embargoes triggered both price explosions and economic collapse.


The Three Components of Stagflation

Element Definition 1970s US Level
High inflation Prices rising faster than normal Peak CPI: 14.8% (1980)
High unemployment More workers without jobs Peak: 9% (1975)
Slow/negative GDP growth Economy contracting or barely growing Multiple quarters of contraction

All three must occur together. High inflation alone is not stagflation. A recession alone is not stagflation.


What Causes Stagflation?

Supply Shocks

The most common trigger. When a key input becomes scarce or expensive — oil, food, semiconductors — the cost of producing everything rises. Businesses cut output, lay off workers, and raise prices simultaneously.

1973–1974 example: OPEC oil embargo quadrupled oil prices overnight. Transportation, manufacturing, and heating costs exploded. The US economy entered recession while inflation soared.

Monetary Policy Mistakes

If a central bank has been printing money (expansionary policy) and a supply shock hits, pre-existing inflation gets worse. The Fed then faces an impossible choice: raise rates to fight inflation (worsening unemployment) or cut rates to fight unemployment (worsening inflation).

Structural Supply-Side Problems

Overregulation, trade barriers, or productivity collapses that permanently reduce the economy’s capacity to produce goods can cause persistent stagflation without a single shock event.


Historical Stagflation Episodes

Episode Country Cause Outcome
1973–1975 (US) US OPEC oil embargo Fed eventually tightened sharply; inflation fell
1979–1982 (US) US Second oil shock + prior monetary expansion Volcker Shock — rates hit 20%; deep recession but inflation broken
1970s UK UK Oil + labor union power + government spending Similar trajectory; resolved via Thatcherite austerity
2021–2023 (partial) Global COVID supply chains + stimulus spending Inflation elevated; growth slowed but unemployment stayed low

Term Growth Inflation Unemployment
Stagflation Low/negative High High
Recession Negative Low-moderate Rising
Overheating High Rising Low
Deflation Low Negative Rising

How to Protect Your Portfolio During Stagflation

Assets that tend to perform well:

  • Commodities (oil, gold, agricultural goods) — prices rise with inflation
  • TIPS — Treasury Inflation-Protected Securities adjust with CPI
  • Energy stocks and materials sectors — revenues rise as commodity prices rise
  • Real estate — rents and property values tend to keep pace with inflation
  • Short-duration bonds — less sensitive to rate increases than long-duration bonds

Assets that tend to struggle:

  • Long-duration bonds — fixed coupons lose real value; prices fall as rates rise
  • Growth stocks — high valuations compress when rates rise and growth disappoints
  • Cash — loses real value rapidly in high-inflation environments
  • Consumer discretionary stocks — demand falls when wallets are squeezed

Worked Example: $50,000 Portfolio in Stagflation

Assume 8% inflation and flat/negative stock market for two years:

Asset Stagflation Return Real Return
Cash (0% yield) 0% –8%
Long bonds (3% coupon) –5% (price falls) –13%
Growth stocks –20% –28%
Commodity ETF +25% +17%
TIPS +8% (inflation-adjusted) 0% (preserves capital)
Energy stocks +30% +22%

A portfolio concentrated in commodities, TIPS, and energy stocks preserved and grew capital; a traditional stock/bond portfolio lost ground in real terms.
