The headline that misleads
German harmonised inflation fell to 2.7 percent in May 2026 from 2.9 percent in April, and on a casual reading that looks like an economy converging back to target. The detail tells a different story. The decline was driven almost entirely by energy and food, where price increases slowed sharply. Underneath, core inflation - the HICP excluding energy and food - rose from 2.3 percent to 2.6 percent, and services inflation remained sticky. Headline disinflation built on volatile components while the persistent core re-accelerates is precisely the configuration central banks fear, because it signals that the underlying inflation process has not yet been tamed.
The energy shock that changed the path
The decisive macro event of the German inflation story in 2026 was external. The Iran conflict pushed wholesale energy higher through the spring, and the Joint Economic Forecast expected it to lift German inflation to around 2.9 percent in the second quarter. The Eurosystem's June projections embedded the shock, raising the euro-area headline path to an average of 3.0 percent for 2026 - materially above the 2 percent target and above where the ECB expected to be a year ago. The June agreement to reopen the Strait of Hormuz has since pulled oil sharply lower, removing the acute risk premium, but the institutes are explicit that energy will remain structurally elevated and that firms will pass the higher costs through into core prices over time.
The energy shock did two things at once. It lifted headline inflation directly, and - more importantly for policy - it threatened to leak into core via cost passthrough and wage demands. The ECB moved not because of the 3 percent headline but because of what the headline might do to expectations and the core.
Passthrough and the wage question
The risk that turns a one-off energy spike into a persistent inflation problem is second-round passthrough: firms raising prices to protect margins, and workers bargaining for compensation. German services inflation - dominated by wages - is the cleanest read on this channel, and it has stayed sticky. The labour market is softening, which should eventually cool wage growth, but the demographic tightness that puts a floor under German employment also supports wage demands. The desk's judgement is that passthrough is the dominant inflation risk for the next year, larger than the direct energy effect that the Hormuz reopening has already begun to reverse.
| Component | Trend | Policy read |
|---|---|---|
| Headline HICP | 2.7%, falling | Flattered by energy |
| Core HICP | 2.6%, rising | The real signal |
| Services | Sticky | Wage-driven, persistent |
| Energy | Easing | Hormuz reopening |
| Food | Slowing | Disinflating |
What it means for the ECB and for assets
A regime of falling headline and rising core, with an energy shock layered on top, is the hardest configuration for a central bank to read - and it is why the ECB raised rates in June for the first time since 2023. For German assets the implications are direct. Real yields on Bunds have risen as the ECB leans against the shock; the euro has been firm; and the equity market faces a higher discount rate at exactly the moment the economy needs cheap capital for its fiscal build-out. The tension between an inflation-fighting central bank and a growth-needing fiscal authority is the defining macro tension in Germany for the coming year.
Our base case is that the energy shock proves largely transitory now that Hormuz has reopened, that core inflation peaks in the second half and grinds lower through 2027 as the labour market cools, and that headline returns toward target by late 2027. The risk is that passthrough and wages keep core above 2.5 percent for longer, forcing the ECB to hold its higher rate well into the recovery and squeezing the fiscal experiment.
