What it means
Economists spent decades assuming inflation and unemployment moved in opposite directions, so that a hot economy produced rising prices and a weak one produced falling ones. The experience of the 1970s, when oil prices jumped while output stalled across the industrial world, showed that both problems could arrive together.
The usual cause is a supply shock rather than excess demand. When the cost of energy, food or shipping rises sharply, businesses face higher costs and consumers have less money left for everything else, so prices rise while activity shrinks at the same time.
Wage and price expectations then make the situation persistent. If workers expect 8% inflation they demand pay rises to match, employers raise prices to cover the wage bill, and the cycle continues even after the original shock has passed.
For central banks the choice is genuinely unpleasant. Tightening policy hard enough to break inflation expectations usually causes a recession, while tolerating inflation risks embedding it, and the historical judgment is that acting late makes the eventual cost far greater.
For businesses, stagflation is a margin problem more than a revenue problem. Input costs rise across the board while customers resist price increases because their own real incomes are falling, so the squeeze arrives from both directions at once.
The practical responses are unglamorous. Shorten supplier contracts so prices can be renegotiated, review your own prices more often than the usual annual cycle, protect cash rather than chase volume, and treat any investment case built on cheap borrowing with suspicion.
In practice
Real-world examples.
Example
A haulage firm faces diesel costs up 22% and driver pay up 11% while customers, squeezed themselves, refuse anything above a 5% rate increase. It responds by dropping its two lowest margin contracts entirely rather than carrying volume that no longer covers its costs.
Example
A homeware retailer sees unit sales fall 7% while its reported revenue rises 3%, because prices went up more than volumes went down. Management resists celebrating the revenue line and instead tracks units and gross margin, which show the business is genuinely shrinking.
Example
A pension fund holding long dated government bonds and growth shares finds both falling together, because rising rates hurt bond prices while weak growth hurts earnings. The trustees add index-linked bonds and commodity exposure, which historically behave better when inflation and stagnation arrive together.
Think of it
“Stagflation is the worst of both worlds-inflation plus economic stagnation.
Formula
Calculation
Real wage growth = nominal wage growth - inflation rate
Misery index = inflation rate + unemployment rate
Take an economy with inflation running at 9%, average pay settlements of 4% and unemployment at 8%. Real wage growth is 4% - 9% = -5%, meaning the average worker can buy 5% less than a year earlier, and the misery index is 9% + 8% = 17%, roughly double what a comfortable economy produces.
Now look at what that does to a single business. Ashfold Bakeries, an invented regional producer, had revenue of $50,000,000 and costs of $44,000,000, giving a gross profit of $6,000,000 and a margin of $6,000,000 / $50,000,000 = 12%. It manages to push revenue up 6% to $50,000,000 x 1.06 = $53,000,000, but its input costs rise with general inflation at 9% to $44,000,000 x 1.09 = $47,960,000.
Gross profit becomes $53,000,000 - $47,960,000 = $5,040,000, a fall of $960,000 or 16% on a business that grew its sales. The margin drops from 12% to $5,040,000 / $53,000,000 = 9.5%, which is the arithmetic behind the familiar complaint that a company is working harder for less.Case study
Seen in the real world.
The following is an illustrative and entirely fictional example. Grantham Kitchens, an invented manufacturer of fitted kitchens, entered a stagflationary period with annual price lists, twelve-month fixed price quotes to housebuilders, and a five-year plan built on 4% cost inflation. Timber, hardware and freight all rose by more than 15% within eight months.
Because quotes were fixed, the company delivered a full order book at prices set before the shock, and gross margin fell from 31% to 19% while revenue grew 8%. Cash tightened at the same time, since the higher cost of materials had to be funded months before the customer paid.
In this fictional scenario the recovery came from contract terms rather than cost cutting. Grantham moved to ninety-day quote validity with a materials adjustment clause, repriced its catalogue quarterly, and accepted losing perhaps a tenth of its enquiries in exchange for margins that survived the next cost increase.
Watch out
Common mistakes.
- Reading revenue growth during high inflation as real growth, when prices alone can lift the top line while the number of units sold falls.
- Assuming interest rate cuts will arrive to rescue a weak economy, when a central bank facing high inflation may keep rates high through the downturn.
- Holding annual pricing cycles through a stagflationary period, which locks in prices set against costs that no longer exist.
Questions
People also ask.
Is stagflation the same as a recession?
No; a recession is falling output, while stagflation adds high inflation on top of it, which is what removes the usual policy response.
Why can't a government just spend its way out?
Extra spending supports demand but adds to the inflation problem, so it tends to make the price side worse while doing little about the supply shortage causing it.
Which businesses cope best?
Those with pricing power, short contracts and low debt, since they can pass on costs quickly and are not exposed to interest rates rising to fight the inflation.
