Inflation cooled.
Your receipt didn’t.

Both can be true. Let’s unpack the gap between the news and the checkout.

Hello there. The word “cooling” sounds reassuring. You might reasonably expect the next grocery bill to get the message. But a lower inflation rate and a lower bill are two different things.

This edition has three stops: a receipt, a shopping basket and a small vocabulary fix. The receipt is hypothetical. The distinction is useful.

01 / CHECK THE RECEIPT

Slower is still up.

A positive inflation rate means the overall price level is rising. If that rate falls, the increase slows; it does not undo the increases that came before. Economists call that disinflation.

The rate fell from 10% to 3%. The basket still ended up $13.30 above its starting price. “Inflation is down” describes the pace—not a return to the old price tag.

02 / LOOK IN THE BASKET

Your life isn’t an average.

The Consumer Price Index tracks changes in the cost of a representative basket. Your own spending mix may look different. So may your experience.

A household with a long commute and one without a car can feel changes in transport prices differently. The headline index provides a broad measure; it is not a personalized account of either household’s bills.

And individual prices can move in different directions. A lower price for one item does not tell you what happened to the whole basket.

03 / SMALL WORD, BIG DIFFERENCE

Disinflation ≠ deflation.

Disinflation: prices, in aggregate, are rising more slowly.
Deflation: the general price level is falling.

One describes a slower climb. The other describes a decline. A single discounted item tells you neither.

GOOD THINGS TO HAVE OPEN

A little question for the next headline: is it talking about a price, a price level or a rate of change? That one distinction clears up a surprising amount.
