Inflation is how fast prices rise. People often forget that, and it leads to a common mistake: when the inflation rate falls, prices do not fall with it. They keep rising, just more slowly. By September 2026, average prices across OECD countries were more than 40 percent higher than in December 2019, even though inflation had dropped 6.7 percentage points from its October 2022 peak by May 2025.
Speed versus distance
Think of inflation as the speed of a car and prices as the distance it has travelled. Slowing from 100 to 40 kilometres an hour does not take you back to the start. Economists call a slower rate disinflation. Prices only fall back under deflation, and a broad fall in prices usually signals a weak economy, which is why central banks aim for low, positive inflation, as inflation targeting shows. For the causes, see what inflation is and why it happens.
Example 1: the grocery basket. Say your weekly groceries cost $100 in December 2019. After a rise of more than 40 percent, that basket costs over $140. If inflation now cools to 2 percent, next year’s bill is about $143, not $100. The good news is a slower climb, not a lower price.
The speed of this rise is unusual. The OECD reported in July 2025 that prices were 33.7 percent above December 2019, a rise that took about 14 years the previous time, from July 2005 to late 2019. This time it took about five and a half years. Since then the pace has picked up again: OECD inflation reached 4.5 percent in September 2026 as energy prices surged, and the IMF expects global inflation of 4.7 percent in 2026, up from 4.1 percent in 2025, easing to 4.1 percent in 2027. Even the hopeful forecast describes slower rises, not cheaper goods.
Why it feels worse than the headline
Not everything rose equally. Food is almost 50 percent more expensive than before the pandemic, and energy close to 70 percent. You cannot skip meals or heating, so these costs weigh more than the average suggests. The official number also measures a typical shopping basket, and your own basket differs.
Example 2: two households. In round numbers, suppose food and energy cost 60 percent more and everything else 40 percent more. A family spending 60 percent of its budget on food and energy sees its costs rise about 52 percent. A family spending only 20 percent on them sees about 44 percent. Same economy, different inflation.
Who bears the cost
The European Central Bank studied the euro area, where inflation jumped from 2.6 percent in 2021 to 8.4 percent in 2022. Lower-income households were hit harder: they spend most of what they earn, have little saved, and often cannot borrow easily, so higher prices hurt straight away. Government help made up about a third of the average loss in living standards and closed around 60 percent of the gap between richer and poorer households. But most of it was not well aimed, so it cost taxpayers more than necessary.
Example 3: a raise that is not a raise. If your pay rose 20 percent since 2019 while prices rose 40 percent, you earn more dollars but can buy less with them. A pay rise is a real gain only when it beats the rise in prices.
How solid is this? The price figures come from official statistics. The effects on households are estimates from a model of the euro area in 2022. The IMF numbers are forecasts and will change. The examples use round, made-up numbers to show the idea.
Key Takeaways
- Watch the price level, not only the rate. When inflation slows, prices still rise, just more slowly.
- Work out your own inflation. If food and energy take a big share of your budget, you likely feel more than the headline figure.
- Check that your income keeps up. Pay, pensions and savings need to grow at least as fast as the prices you pay.
- Expect an uneven burden. Lower-income households are hit hardest, so help works best when aimed at them.
- Treat forecasts as ranges. They describe likely paths, not promises.
