Inflation 3.4 percent, wages 3.2 percent: the gap you never see

The consumer price report published on 12 August showed a rise of 0.1% in July against June and 3.4% over the year, down from 3.5% the previous month. Core inflation, which strips out food and energy, rose 0.2% on the month and 2.5% over the year.

Markets read it as good news. There is a second number that circulates far less.

Inflation is running faster than pay

Average hourly earnings rose 3.2% over the year, according to the employment report of the previous week. Inflation is running at 3.4%.

The gap looks negligible at two tenths of a point. The direction is not negligible. As long as inflation stays above wage growth, purchasing power falls, regardless of whether the salary itself went up in absolute terms.

This is also why the phrase inflation eased is misread so consistently. It does not mean prices fell. It means they are rising more slowly than before. A basket that became 20% more expensive over three years does not return to its old price because this year it only rises 3.4%. The full explanation of inflation shows why prices rarely go back down and what that does to savings.

Where the number hides

Roughly two thirds of the monthly increase came from shelter. Food and shelter each rose 0.1%.

Shelter enters the index with a long lag, because rents renew gradually across the year and the index tracks all leases rather than only new ones. So it shows today something that started months ago. That is why headline and core inflation rarely turn at the same moment, and why central banks always react late compared with what a household already feels.

Why markets were pleased

Traders cut the probability of a September rate increase to 42%. The S&P 500 closed at a record the same day, helped as well by falling oil prices.

Notice the order, because it explains a great deal about how markets work. The data did not change the economy. It changed the estimate of the central bank's next move. Markets did not react to inflation, they reacted to the interest rate they now consider more likely. The same reading, arriving after different expectations, would have produced the opposite reaction.

What it means for your own money

Inflation is not only a supermarket matter. It is the threshold every investment has to clear. A deposit paying 2% while prices rise 3.4% loses purchasing power, even though the balance on the statement grows.

This is called the real return and it is the only one that matters over time. Across ten years, a gap of one and a half percentage points a year changes the final amount in a way that is hard to picture while looking at a single month. Compound interest works in both directions, and the Investment Calculator makes it visible with your own numbers.

What to take away

• Inflation at 3.4% with wages at 3.2% means slightly negative real income growth. Pay rises, the basket rises a little more.
• The same mechanism applies to investing: a return below inflation is a loss in real terms.
• One month at 0.1% is not a victory. It is a single reading inside a series that is already years long.
