Inflation & Deflation — Wage-Price Spirals
The Spiral That Isn't: Why the Most Feared Inflation Story Rarely Happens
Every time workers win a pay rise during an inflationary period, economists nervously invoke a 1970s ghost — but the wage-price spiral may be one of the most misused concepts in all of economics.
The Idea
The basic story sounds airtight: prices rise, workers demand higher wages to keep up, companies pass those higher labour costs on as even higher prices, workers demand more again, and so the spiral tightens. It is the inflation equivalent of a runaway train — and it is frequently cited by central banks and commentators as the reason wage growth must be suppressed during inflationary periods. The trouble is that this mechanism, while theoretically coherent, is empirically quite rare. A 2022 IMF working paper examined 79 episodes of sharply rising inflation across advanced economies since the 1960s and found that the classic wage-price spiral — where both wages and prices mutually and persistently accelerate — occurred in fewer than one in ten cases. What actually happens more often is a wage-price catch-up: workers' real wages fall when prices spike, they eventually recover some of that ground through negotiation, and the process stabilises rather than accelerates. The spiral requires a very specific set of conditions — strong worker bargaining power, widespread cost-of-living indexing in contracts, and an expectation among consumers and firms that inflation is permanent. Strip away any one of those, and the feedback loop breaks. This matters because the *fear* of a wage-price spiral can itself become a policy tool, used to argue against wage increases even when the evidence for an actual spiral is thin. The story is easy to tell, hard to falsify in the moment, and very useful to those who prefer that labour absorb the cost of price shocks rather than capital.
In the World
The clearest historical example of a genuine spiral unfolding is the United Kingdom in the 1970s. The context was specific and dense: oil shocks from 1973 had already sent prices surging, but the critical ingredient was institutional. Many British workers had contracts with automatic cost-of-living adjustments — so when the retail price index rose, wages rose with it, almost mechanically. Unions were at their peak membership and bargaining strength. And crucially, the Bank of England was operating without an explicit inflation target, meaning there was no credible commitment to bring inflation back down, so firms and workers planned for it to stay high. By 1975, UK inflation had reached 25%. Prime Minister Harold Wilson's government eventually imposed a flat pay cap — limiting rises to a fixed amount per week regardless of salary — in an attempt to break the spiral. It partially worked, but the damage to trust between government, unions, and employers was lasting. Now contrast that with the inflation surge of 2021–2023. Central banks in Europe and North America were flooded with warnings that a 1970s-style spiral was imminent. In most cases, it did not materialise. In the United States, real wages initially fell sharply as inflation outpaced pay growth — the opposite of a spiral. In Germany, despite strong union activity, wage settlements remained broadly anchored. The conditions for a spiral — entrenched expectations, indexed contracts, sustained policy accommodation — simply were not present in the same way. The ghost appeared on the wall; the haunting, mostly, did not follow.
Why It Matters
Understanding this changes how you interpret a very common argument you will encounter whenever inflation rises and workers push back. 'We can't raise wages — it'll just cause more inflation' sounds like economic prudence, but it embeds a contested empirical claim as if it were settled law. For your own thinking, this is a useful template for a broader skill: distinguishing between a mechanism that *can* happen and one that *typically* happens. Economics is full of feedback loops that are theoretically possible but empirically fragile — they require precise conditions that may or may not be present. When someone invokes a spiral, a trap, or a tipping point, the sharp question to ask is not 'is this theoretically possible?' but 'what conditions would need to hold for this to actually occur, and do they?' It also reframes how you think about who bears the cost when prices rise. Inflation is not a natural disaster that distributes pain randomly. The question of whether workers recover their purchasing power, or whether it stays eroded, is a political and institutional question as much as an economic one — and the stories we tell about spirals shape which answer we reach.
A Question to Ponder
When you hear an economic warning framed as an inevitable chain of cause and effect, how would you go about checking whether that chain actually tends to complete — or whether it usually breaks somewhere?
