Eurozone inflation ticks up to 2.1% in August, keeping ECB on hold

Eurozone inflation edged above the European Central Bank's target in August, rising to 2.1% from 2% in July, according to the flash estimate released by Eurostat on Tuesday. The increase, though modest, caught forecasters off guard: a Reuters poll of economists had predicted the rate would hold steady at 2%. The data arrives one week before the ECB's next policy meeting, where the governing council is widely expected to keep its key interest rate at 2% for the third consecutive session.

The numbers in detail

Headline inflation's 0.1 percentage point rise masks divergent moves underneath. Core inflation, which excludes volatile food, energy, alcohol and tobacco prices, remained anchored at 2.3% for a second month. The more closely watched services component, a gauge of domestic price pressures that the ECB tracks intently, slipped to 3.1% from 3.2% in July, its lowest level since March 2022. Energy prices, which subtracted from the headline figure for much of 2024, are no longer a drag; food, alcohol and tobacco inflation ticked up slightly, contributing to the headline overshoot.

The persistence of core inflation above headline is not new. Since late 2023 the gap has widened as goods disinflation outpaced services. What matters for policymakers is the direction of travel in services, where wage growth and profit margins interact most directly. At 3.1%, services inflation is still well above the 2% target, but the downward trend since its peak above 5% in early 2023 is intact. The August reading suggests the disinflation process has not stalled, even if the headline number moved the wrong way for a month.

Market reaction muted but telling

Financial markets took the news in stride. The euro weakened 0.6% against the dollar to $1.1640, reversing part of the gain it had built since the ECB's July meeting. The pan-European Stoxx 600 index fell 0.7% in morning trading. Money markets continue to price roughly a 50% chance of a quarter-point rate cut by December, a probability that has barely shifted since the summer. The limited reaction reflects a consensus that one month's flash estimate does not alter the ECB's calculus when core and services measures are both moving in the right direction.

ECB policy outlook: hold for longer

The central bank held its deposit facility rate at 2% in July after a sequence of cuts that brought it down from 4% in June 2024. President Christine Lagarde has repeatedly stressed that the governing council will be "sufficiently restrictive for as long as necessary" and that decisions will be data-dependent, meeting by meeting. The August inflation print, while slightly above target, does not meet the threshold for a policy response when the underlying trend remains favourable.

Andrew Kenningham, chief Europe economist at Capital Economics, was blunt in his assessment. "ECB policymakers look certain to leave interest rates unchanged at next week's meeting and probably for several months beyond that," he wrote in a note to clients on Tuesday. He highlighted the services figure as the most important for the ECB, noting it was the lowest since March 2022 and should reassure policymakers that domestic price pressures are continuing to subside. He predicted services inflation would fall further in coming months as labour market conditions ease.

Analysts converge on a patient ECB

Irene Lauro, eurozone economist at Schroders, struck a similar tone. "With trade uncertainty easing, the Eurozone recovery is set to gain momentum as firms ramp up borrowing and investment," she said. "In this environment, the ECB is likely to hold rates cautiously steady in September. The resilience in core inflation supports our view that policy normalisation has ended, and the ECB will closely monitor growth dynamics before making its next move." The phrase "policy normalisation has ended" is significant: it implies the cutting cycle that began in June 2024 is effectively over, and the next move, whenever it comes, could be in either direction.

Both analysts point to the same tension. Growth is fragile, the eurozone eked out just 0.1% quarter-on-quarter expansion in the second quarter, but not collapsing. The EU-US trade deal signed in late July removed the threat of higher tariffs, though a blanket 15% duty on EU exports to the United States remains in place and could weigh on activity. The ECB's own staff projections from June saw growth picking up to 1.3% this year and 1.5% in 2026, but those forecasts predate the summer's trade negotiations and the recent softening in German industrial output.

The growth-inflation trade-off

The ECB's mandate is price stability, but its decisions inevitably weigh on growth. With inflation only marginally above target and core measures decelerating, the argument for further restriction has evaporated. The argument for cutting, however, rests on a growth outlook that is uncertain rather than dire. That leaves the governing council in a holding pattern: rates stay where they are until either inflation re-accelerates convincingly or growth disappoints sharply.

This is not the first time the ECB has paused at this level. In late 2023 and early 2024, the deposit rate sat at 4% for five meetings while inflation fell from 5.2% to 2.4%. The current pause at 2% may prove shorter if the economy weakens, but the bar for a cut is higher now because the policy stance is no longer clearly restrictive. Neutral rate estimates for the eurozone cluster around 2% to 2.5%, meaning the current setting may already be close to neither stimulating nor restraining activity.

What the flash estimate does not show

Flash estimates are preliminary. They are based on incomplete national data and do not break down the drivers by country or sector. The full harmonised index of consumer prices, due on 17 September, will reveal whether the headline uptick came from Germany, France, Italy or the smaller member states, and whether it was driven by package holidays, rents, insurance or other volatile components. National flash releases on Monday and Tuesday morning already hinted at the surprise: German inflation came in at 2.3% versus 2.1% expected, French at 1.8% versus 1.6%, Spanish at 2.4% versus 2.2%. The aggregate beat was broad-based.

Also missing from the flash is the administered prices component, regulated tariffs for electricity, gas, transport, which can swing the headline by a tenth or two in any given month. The ECB's models strip these out when assessing underlying inflation, but they matter for household purchasing power and political sentiment. With winter approaching, energy price caps in several large economies could re-enter the picture.
