Euro-area inflation rose to 3.2% in August, up from 2.9% in July, according to Eurostat's final figures published on 17 September. In the UK, the Office for National Statistics reported a rise to 3.1%, also from 2.9%. On the surface, that looks like inflation picking up again.
It isn't. Or at least, not in the way that matters most for monetary policy. Both rises were narrow and energy-driven — not the kind of broad-based pressure that central banks are trying to squeeze out of the system.
Energy did the heavy lifting
Eurostat's flash estimate put euro-area energy inflation at 14.3% in August, up from 10.3% in July. That single component contributed roughly 0.9 percentage points to the overall 3.2% headline rate. Every other main component was far lower: services at 3.0%, and both non-energy industrial goods and food, alcohol & tobacco at 1.2%.
The UK told the same story. The ONS said motor fuels made the largest upward contribution to the change in the annual rate, while services inflation stayed at 3.4% for the third consecutive month — a level the Bank of England has been watching closely as a gauge of domestic price persistence.

Core measures barely moved
Core inflation strips out volatile items like energy and food. In the UK, CPI excluding food, energy, alcohol and tobacco held at 2.6%. In the United States, where headline inflation held at 3.4%, core fell to 2.4% — its lowest since March 2021. That US core reading — detailed in our US release note — reflects broad easing in goods, airfares, and medical care.
The euro-area core (HICP excluding energy, food, alcohol and tobacco) also held at 2.6%. Services — the stickiest part — eased slightly from 3.3% to 3.0% between flash and final, which itself was the subject of a small downward revision covered in our flash vs final explainer.
When the headline jumps but core stays put, the move is usually about a few volatile prices — not a broad rise in the cost of living.
What the central banks will take from this
The ECB and the Bank of England both use core measures to guide policy decisions, precisely because headline rates are noisy when energy prices swing. August's data — stable core in both economies — is unlikely to shift the policy needle on its own. Markets will focus more on September's readings, which will show whether the energy impulse was a one-off or the start of a renewed push.
What to watch next
The euro area's September flash estimate is due on 2 October (see our release calendar). US figures for September follow on 14 October via the Bureau of Labor Statistics. Both readings will tell us whether August's energy-driven jump was temporary or the opening of a new chapter.
