Porto: Eurostat releases the August flash estimate for euro area consumer prices tomorrow morning, and the interesting question is not the headline number. It is how much of that number one component produces. July’s reading put annual inflation at 2.9 percent, a tenth above June. Strip the detail out and the story turns almost entirely on energy.

Energy prices rose 10.0 percent over the year in July, against 8.5 percent in June. No other component came close to that movement. Services registered 3.3 percent, barely changed from 3.2 percent. Non-energy industrial goods sat at 0.9 percent. Food, alcohol and tobacco actually fell, from 1.5 percent to 1.2 percent. Three of the four baskets behaved calmly, and one did not.

Why a single component moves the headline

Energy carries roughly a tenth of the consumption basket, so a double-digit annual rate translates into approximately one percentage point of headline inflation on its own. Remove it and the euro area looks close to target rather than above it. That arithmetic explains why the European Central Bank has spent the summer pointing analysts toward core measures and why governing council members keep describing the current phase as bumpy rather than resurgent.

Base effects deserve most of the credit for the recent climb. Energy prices fell sharply through the middle of 2025, so this year’s comparison runs against an unusually low reference. Nothing dramatic has to happen at the pump for the annual rate to look severe. The same mechanism will unwind once the base normalises, and it will unwind without any policy decision at all.

Services carry the more durable signal. That component tracks wages more closely than any other, and it has now held above three percent for an extended stretch while the rest of the basket cooled. A rate that refuses to fall despite weak goods inflation indicates domestic cost pressure rather than imported shock. Central bankers watch this line because it responds to interest rates, whereas gas markets largely do not.

A labour market that keeps refusing to crack

The employment data explain why services stay warm. Euro area unemployment stood at 6.3 percent in June, unchanged from May and unchanged from a year earlier. Women recorded 6.4 percent and men 6.2 percent. Second-quarter output grew 0.4 percent on the previous quarter. Those figures describe an economy expanding slowly while holding on to its workers.

Employers who fear they cannot rehire tend not to fire, and workers who feel secure tend to press for pay. That combination sustains services inflation long after energy and goods have settled. It also keeps household demand steadier than a growth rate of 0.4 percent would normally suggest.

National dispersion complicates any single reading. Southern economies with heavy tourism exposure report different services dynamics from manufacturing-led members facing weak external demand. A euro area aggregate near three percent can conceal a spread of well over a point between the highest and lowest members, and monetary policy operates on the aggregate regardless.

For tomorrow’s release, one comparison matters more than the headline. If energy decelerates and the headline still holds near 2.9 percent, services or goods will have picked up the slack, and the disinflation story loses its cleanest defence. If energy stays elevated while services ease below 3.2 percent, the reverse applies, and the Governing Council gains room it does not currently have.

Markets will react to the first decimal place. The composition tells the more useful story, and it takes only a minute longer to read.
