Despite market disappointment after the early 2024 data, a further decline in inflation is likely. The producer price index (PPI) of manufacturing goods, which historically leads eurozone Harmonized Index of Consumer Prices (HICP) inflation, has been falling on an annual basis since mid-2023.
Also, the services PPI declined in Q3 2023 from a year before, pointing to a pronounced slowdown in services HICP inflation. However, services HICP inflation remains around 4% YoY and, unlike the other HICP components, has not declined much when looking at the annualised changes over six months (see Chart 2b).
The ECB relates the stickiness of services HICP to past strong wage increases and is concerned that high wage growth could prevent the return of inflation to the 2% target. The marginal slowdown in wages in Q4 2023 and in early 2024 is not seen as indicating that wage inflation has peaked (see Chart 3). Furthermore, it remains to be seen how fast wages will normalise with the unemployment rate at a historic low of 6.4%.
