The German PPI is falling by 1.1% in July compared to June. The PPI now has a string of months in which prices are falling. This in fact looks even more persuasive because the PPI ex-energy fell by 0.4% in July, and it also has a string of months in which inflation is falling. But it’s only PPI inflation, not the sky. Central banks do not target producer prices. Table 1 also shows for comparison what's going on with the CPI; it has increased in two of the last three months. The CPI ex-energy has also increased in two of the last three months. As you look at these trends more broadly, producer prices are in fact coming to heel very sharply. And more than that, PPI prices are weak. However, consumer prices have hardly benefited from this trend at all.
The PPI excluding construction in Germany has fallen by 6% over 12 months; it falls at a 10.1% annual rate over 6 months and falls at a 10.4% annual rate over 3 months. That's impressive weakness. The PPI excluding energy rises 2.1% over 12 months, falls at a 1.1% annual rate over 6 months and falls at a 3.9% annual rate over 3 months indicating ongoing deceleration in the PPI ex-energy.
In comparison, the CPI, which is emphasized by the ECB (it targets the HICP), is up by 6.1% over 12 months; however, the pace slows to 3.5% over 6 months and slows further to 1.7% over 3 months. This declining progression brings the 3-month growth rate inside the target range for the ECB, but again central banks do not typically place a great deal of weight on these shorter-term compounded inflation rates. Looking at the CPI ex-energy we also see a 6.1% gain over 12 months, a 4% annual rate gain over 6 months, and a 2.5% annual rate gain over 3 months. Once again, we see clear inflation deceleration and progress but less deceleration than for the headline and even over 3 months there is less good news when the CPI ex=energy fails to drop inside of the ECB target range.
The chart (on the right) plots the PPI ex-energy against the CPI ex-energy. The chart is perhaps the best way to understand the stark difference and the difference in trend between these two metrics. The chart gives you a hint that historically the PPI is more volatile than the CPI and that it goes through exaggerated cycles in comparison with the CPI. In other words, just because the PPI accelerates sharply or decelerates sharply doesn't mean the CPI will run the same magnitudes; however, usually, the accelerations and decelerations of the PPI are reflected in some acceleration or deceleration in the CPI. It's just less pronounced. That seems to hold in this cycle as well.
