The German PPI broke sharply lower in October with the PPI excluding construction falling by 4.2% month-to-month; it rose 2.4% in September and 7.9% in August. The sequential growth rates for this headline PPI show a 34.5% rise over 12 months, a rise at a 30% annual rate over six months, and a gain at a 25.4% annual rate over three months. The inflation process shows a clear slowdown but still very high rates of change in headline producer prices.
But there is a huge gap between the PPI and the PPI excluding energy. The PPI ex-energy did not move lower this month. It rose by 0.5% in October, the same as in September; in August it rose by 0.4% month-to-month. The German PPI excluding energy is up by 13.4% over 12 months; it's up at a 6.1% annual rate over six months, and that drops off to a 5.4% annual rate over three months. I have plotted the ex-energy PPI in the chart above.
Like the headline PPI, the PPI ex-energy shows a deceleration in progress despite the much lesser role of oil and the exclusion of energy prices from this index. Most interesting is the huge gap between the growth rates of the PPI excluding energy and the headline PPI. The PPI ex-energy rises 13.4% over 12 months while the headline PPI rises by 34.5%. That's close to three times faster. Obviously, energy and commodity prices have a lot to do with what's been going on with inflation.
The October reading marks the first observation in the fourth quarter. Fourth quarter-to-date inflation for the headline is falling by 1.3% at an annual rate, but for the core it's still rising at a 5.5% annual rate, in line with its sequential progression.
Monetary policy and prices Monetary policy of course is made at the European Monetary Union level by the European Central Bank not in Germany by the Bundesbank. However, Germany has a high weight in the monetary union and its price developments are important period; it's instructive to look at the difference between the German CPI and the PPI to see what's going on with different metrics for inflation. Through October the German CPI is rising at a 10.4% rate year-over-year, the same as over six months; the pace rises to a 15.8% annual rate increase over three months. The CPI does not show the same headline drop-off that the PPI does since it accelerates. The PPI gives energy and commodities a much greater weight and the services sector is substantially diminished. The CPI and PPI are quite different.
Likewise, the CPI excluding energy is up by 6.5% over 12 months; that pace accelerates to 7.8% over six months and accelerates further into double digits at an 11.3% annual rate over three months. One month into the fourth quarter, the CPI is rising at a 16.7% annual rate where the core is up and 11.5% annual rate.
Oil and OPEC Underlying these statistics is oil. Brent oil prices are up by 10.8% over 12 months; they fall at a 23.3% annual rate over six months and fall at a 38.3% annual rate over three months. Clearly the weakness in oil prices has been helping the headline prices to behave. However, oil prices fell by 7.2% in August and by a further 7.5% in September but then rose by 3.2% in October. OPEC is trying to put a floor under oil prices and that may make the progressive results for the PPI headline just a little bit less relevant.
