The final inflation figure for the eurozone in August did not maintain the preliminary estimate of 3.3% at the beginning of the month. Eurostat On September 17, the eurozone's Harmonized Consumer Price Index HICP rose by 3.2% year-on-year, higher than 2.9% in July and 2.0% in the same period last year; it also increased by 0.4% month-on-month. The overall inflation rate for the European Union was also 3.2% year-on-year, up from 3.0% in July. The final figure was revised down by 0.1 percentage points from the preliminary estimate, which is not a significant change, but it serves as a reminder to the market that the preliminary figure was a quick estimate, not the final result.

The core driving factor for this upward trend remains energy. Eurostat When broken down by contribution to overall inflation, services contribute 1.43 percentage points, energy contributes 1.29 percentage points, non-energy industrial products contribute 0.30 percentage points, and food, alcohol, and tobacco contribute 0.22 percentage points. Services have the largest contribution because of their high weight in the consumption basket; although energy has a faster year-on-year increase, its contribution is slightly lower than that of services due to its smaller weight. When looking at inflation, one cannot simply compare the year-on-year increases of individual components; weight also needs to be taken into account.

Excluding energy, the year-on-year inflation rate was 2.1%, lower than 2.2% in July; excluding energy and unprocessed food, it was also 2.1%. The more commonly used core inflation measure, which excludes energy, food, alcohol, and tobacco, was 2.4%, down from 2.5% in July. The acceleration of overall inflation and the moderation of core indicators are not contradictory: energy prices drive up the overall index, while the slower pressure on underlying prices has not yet worsened accordingly.

Energy drives up the total, and slower services make the inflation structure not as straightforward as it might seem

Early-month estimates suggested a year-on-year increase in energy prices of 14.3%, services by 3.0%, and non-energy industrial products by 1.2%, with food, alcohol, and tobacco also showing a 1.2% increase. The final figures confirmed an overall rise in inflation, but the total figure was revised down from 3.3% to 3.2%. When interpreting these figures, what is most important is not to get bogged down in the 0.1 percentage point difference, but rather to determine how long the impact on energy prices will last and whether the pressures on services and wages will continue to decline.

Energy prices are sensitive to international oil and gas prices, exchange rates, taxes, and base effect. When prices were lower during the same period last year, the same level this year could also result in a higher year-on-year increase. The impact of the base effect varies with the month, so a year-on-year increase of around 14% in energy prices cannot be mechanically extended over a year. If oil and gas prices remain stable, the contribution of energy to year-on-year growth may naturally weaken; if supply tightens again, the impact could also be prolonged.

Service prices tend to be more sticky, as adjustments to wages, rent, and local operating costs are slower. Services still contribute 1.43 percentage points, indicating that they have not withdrawn from the inflation narrative; however, the core inflation rate has dropped from 2.5% to 2.4%, providing a slight sign of moderation. Central banks will pay attention to whether this change is sustained and will not ignore the internal structure just because the overall figure for a single month has risen.

There are significant differences among member countries. In August, the lowest annual inflation rates were seen in Sweden at 0.3%, Estonia at 1.3%, and the Czech Republic at 1.5%; the highest rates were in Romania at 6.3%, Lithuania at 5.6%, and Cyprus at 5.2%. Compared to July, inflation decreased in six member countries, remained unchanged in one, and increased in twenty. The unified interest rates of the eurozone are not faced with a uniform price environment, and the pressures on households due to food, energy, and housing costs also vary from country to country.

HICP is used for cross-country comparisons and is not exactly the same as the local consumer price indices of various countries. Differences in basket weights, housing treatment, and statistical methods can lead to different results for HICP within the same country compared to the domestic CPI. When discussing the policies of the European Central Bank, HICP should be given priority, while analyzing local living costs, it is also necessary to consider that country's statistical criteria.

The downward revision of the terminal value has weakened the potential for a "further acceleration," but it is not sufficient to draw conclusions about the interest rate path.

3.2% is still significantly higher than the medium-term target of 2%, but monetary policy focuses on future inflation, rather than simply catching up with already occurring increases in energy prices. If core and service sector growth continues to slow down, the short-term rise caused by energy prices may not necessarily require a corresponding policy response; however, if the energy shock affects wage and pricing expectations, the risks will become more persistent. To assess these two scenarios, it is necessary to verify them jointly with wage data, profit margins, survey expectations, and subsequent monthly data.

The difference between the initial value and the final value also illustrates the limitations of high-frequency trading. At the beginning of the month, the market adjusted its expectations to 3.3%, but half a month later, the complete data showed 3.2%. This correction does not indicate that the early estimates were incorrect; rather, it reflects the fact that rapid estimations were made using incomplete information. Formal analyses should clearly indicate the version of the data, and it is not acceptable to continue treating the initial value as a confirmed fact after the final value is released.

For consumers, the overall index does not represent inflation for everyone. Families that use cars frequently are more sensitive to fuel costs, while renters are more affected by housing and service expenses. Low-income families often have a higher proportion of their budgets allocated to food. The average weightings used in the eurozone are suitable for macro-level comparisons but cannot accurately reflect the expenses of individual households. Differences among member states, along with variations in family structures, mean that an average of 3.2% can mask a wider range of actual experiences.

For businesses, energy shocks first affect transportation, manufacturing, and public utility costs, and whether these costs can be passed on depends on demand and competition. The service industry is more concerned about wages and rent, while manufacturers also need to consider import costs and exchange rates. A slight decline in core inflation means that the pressure for widespread price increases has not escalated simultaneously, but it does not guarantee that profit margins will not be squeezed.

Eurostat The next full inflation report is scheduled for October 16th. September's data may continue to be affected by energy costs and the base effect, and the core inflation trend will also need to be confirmed over at least a few more months. The conclusion that can be drawn today is clear: inflation in the eurozone did indeed rise from 2.9% to 3.2% in August, but it is lower than the preliminary figure of 3.3%; energy costs were a significant driver of this increase, while the core inflation rate actually fell slightly. It would be premature to describe this as a "full-blown re-inflation," and it is also lacking evidence to claim that it is "negligible energy-related noise."
