German PPI Continues to Behave

Inflation reports are still very much of market interest largely because inflation remains in the forefront, sufficiently contained, to allow central banks to choose a policy course of easing monetary policy. To stay on that course, they will need for inflation to remain under control.

The German PPI in September is flat after falling 0.5 in August and rising only 0.1% in July. The PPI excluding energy has flattened in July, fallen by 0.2% in August and is up by only 0.1% in September. Both of these PPI series generate significant optimism sequentially as well. The PPI headline series falls by 1.7% over 12 months; it falls at a 2.5% annual rate over 6-months, and it falls at a 1.6% annual rate over 3-months; its change is negative on all three horizons. Inflation is quite contained and reinforcing of the theme of cutting interest rates from the standpoint of the monetary authorities.

For the PPI excluding energy inflation is up by 0.9%, Over 12-months it rises at a slower 0.7% annual rate over six-months and the PPI excluding energy falls by 0.3% over 3-months. The contained status of headline inflation is thus translated into the core so that the sequential core pattern shows inflation progressively lower measured over longer to shorter periods. For the German economy, its good news from the standpoint of inflation although part of the cost of this is that the German economy has been exceptionally weak.

The details of the PPI are a little bit less interesting because they're not seasonally adjusted, however, consumer goods, investment goods, and intermediate goods, trends are working lower.

Comparing the PPI to the CPI - and to the CPI excluding energy - we see that the excellent PPI trends do not translate directly into solid CPI inflation. CPI inflation is somewhat erratic but at 2.4% over 12-months and at 3% over three months, and the CPI ex-energy at 2.6% over 12-months and much higher at 3.4% at an annual rate over three-months, the German CPI has more work to do.

Still the underpinning of a solid PPI report is reassuring. With Brent oil prices off by about 7% over 12-months and falling at a 15% annual rate over three-months, the beneficial inflation trend is being driven by weakness in oil prices. And that does help the PPI more and faster than the CPI.
