Disinflation
A slowdown in the rate of inflation: prices are still rising, just more slowly than before.
In plain words
Disinflation happens when inflation is still positive but getting smaller. If prices rose 8% last year and 3% this year, that's disinflation: things are still getting more expensive, only at a slower pace.
Prices don't go back down during disinflation — for that you'd need deflation. Central banks usually aim for disinflation after an inflation spike, bringing the rate back towards their 2% target without tipping into falling prices.
Think of it as a car slowing down but not stopping. The speedometer drops from 80 mph to 30 mph — you're still moving forward, just less rapidly. The total distance already covered doesn't shrink.
The rate fell sharply — but prices never reversed.
Don't mix them up
Three terms describe the direction and speed of price changes. Only one means prices are actually falling.
The rate is above zero. Money buys a little less each year.
e.g. US 2018: +2.4%The rate is falling but still above zero. Prices keep climbing, at a gentler pace.
e.g. US 2022→2024: 8.0% → 2.9%The rate is below zero. The same money buys more than it did a year ago.
e.g. Armenia 2016: −1.4%How it's measured
There is no official threshold for how far or how long the rate must fall. In the InflationTheGuide, we call a period disinflation when the 12-month rate has fallen for at least three months in a row while staying above zero.
π(t) = I(t) ÷ I(t − 12) − 1 12-month inflation rate from the price index I 0 < π(t) < π(t − k) Disinflation: the rate is falling but still above zero π(t) < 0 Deflation: the rate has crossed below zero Why it matters
Your costs are still going up. A lower rate means a slower climb, not cheaper shopping. After two years of disinflation the price level is still higher than at the peak.
When inflation falls while interest rates stay put, real rates rise — good news for savers, tougher for mortgage holders. Disinflation changes the terms without anyone touching a lever.
Disinflation is central banks' goal after a spike. A "soft landing" means engineering disinflation without causing unemployment to surge or deflation to take hold.
The "soft landing" challenge
Central banks must slow inflation without breaking the economy. That's harder than it sounds.
Common misreadings
"Inflation is down, so prices are falling."
Prices are still rising, just more slowly. Only deflation brings prices down. During disinflation, the accumulated price increases from the spike remain.
"Disinflation is the opposite of inflation."
The opposite of inflation is deflation. Disinflation is a change of speed, not of direction. Prices still rise during disinflation — just at a slower rate.
"Lower inflation means my savings are safe."
Money still loses buying power whenever inflation is above zero. Lower inflation just means the erosion is slower — not that it stops. You need your return to exceed inflation to preserve real value.
Frequently asked questions
What is the difference between disinflation and deflation?
Disinflation is a slowdown in the rate of inflation — prices still rise, just more slowly. Deflation is when the rate turns negative and prices actually fall. They sound similar but have very different economic implications: disinflation is usually desirable, while sustained deflation can cause a damaging economic spiral.
Is disinflation good or bad?
Generally good when inflation has been too high — it means price pressures are easing toward a healthier level. Central banks engineering a "soft landing" aim for disinflation, not deflation. It only becomes problematic if it overshoots into deflationary territory, which can trigger an economic spiral of falling demand and prices.
How long does disinflation typically last?
It varies widely. The US disinflation from the 2022 peak took roughly two years (2022–2024). The Volcker disinflation in the early 1980s took about three years but required very sharp rate rises that caused a recession. Some disinflation episodes have been gradual and lasted a decade.
Do prices fall during disinflation?
No. During disinflation prices are still rising — just at a slower rate than before. The price level keeps climbing; only the speed of the climb decreases. To see prices actually fall, you need deflation (a negative inflation rate). Many people confuse the two terms, especially when headlines say "inflation fell to 3%."
