On the day that the European Central Bank met and decided to raise interest rates by 25 basis points, the German inflation report for August firmed, showing that headline inflation rose 0.3% on the month, with the core rising by 0.1%. Year-over-year headline inflation in Germany is excessive at 3%. However, the core rate at only 2.3% is not that far above the ECB target for all of the monetary union, a pace of 2%. German inflation for the headline is 3.6% over six months and 3.7% over three months; however, over three months and six months, German core inflation is running at 2%, the ECB’s chosen speed for inflation for the union as a whole.
German core inflation provides a counterpoint to headline inflation. It enables a strong argument that energy price inflation has not spread throughout the monetary union. However, with the ECB raising rates, German bond yields have risen to a 17-year high and the ECB seems determined to treat energy price inflation as something important and significant that it needs to fend off.
Economic conditions still show growth in the monetary union as weak at 1.0%. Growth among the top four economies is 1.1% with growth for the rest of the union year-over-year at 0.5%. So, the ECB is raising interest rates in an environment where growth is modest-to-low and where headline inflation is surging but where core inflation is much better behaved. The pace for Germany at 2% over three months and six months is right on target; 2.3% over 12 months is slightly excessive. For the entire euro area, the core inflation rate is closer to 2.5%, which is uncomfortable but not a terrible overshoot, certainly not with energy prices having flared the way they have.
Diffusion statistics show that inflation over three months in Germany has accelerated in only 27.3% of the categories; however, inflation has accelerated in 72.7% of the categories over six months and in 63.6% of the categories over 12 months. The tempered three-month inflation rate breadth does not dominate the other two metrics; however, it provides another counterpoint to the notion that inflation from oil price increases is spreading.
