German inflation was delightfully low in March, falling by 0.2% month-to-month after rising by only 0.1% month-to-month in both February and January. Over the last three months, the German HICP headline pace has fallen, and is contracting at a 0.3% annual rate, compared to climbing 2.6% at an annual rate over six months, and climbing 2.5% at an annual rate over 12 months. This excellent three-month performance, of course, is also embedded in the too-hot six-month and 12-month rates of change. It serves as evidence that, as delightful as the recent data have been, German inflation continues to run over the top of the target set by the ECB for the European Monetary Area.
Domestic CPI The domestic CPI that has a different weighting scheme shows inflation up by 0.2% in March and February, compared to a 0.1% gain in January. The inflation performance for the German domestic CPI is 2.2% over 12 months, 2.7% over six months and 1.7% over three months. It also behaves much better over three months than over six or 12 months; in fact, the 12-month gain in the domestic CPI is even closer to the ECB's desired outcome. Still, the German inflation rate continues to run hot except over three months. Looking at German inflation and its CPI excluding energy, which was up 0.3% in March, compared to 0.2% in February, and no gain in January. The inflation sequence for German domestic inflation excluding energy is 2.7% over 12 months, 2.7% over six months, and then down again to 1.7% over three months.
Germany displays improved and in fact acceptable inflation over the last three months; however, over a broader timeline, it still isn't good enough for the target that the ECB has for the EMU area. Still, if we look at diffusion statistics which assess the breadth of inflation acceleration across periods, we see the diffusion over 12 months is only 27%, over six months it's only 36%, and over three months it's only 36%. Diffusion at 50% would indicate acceleration and deceleration are balanced. But with diffusion below 50%, that's telling us that inflation is actually decelerating across more categories than it's accelerating. Germany displays impressive decelerating statistics across these categories for 12-months compared to 12-months ago, for 6-months compared to 12-months, and for 3-months compared to 6-months. The reality is that inflation continues to overshoot, that is simply the reality that inflation is stubborn in several important categories where it refuses to fall enough to register the desired result of 2% overall.
However, very clearly inflation in Germany is not running away. It is slightly excessive, and the overshoot depicted by the domestic headline at 2.2% would probably be acceptable in these times, but the overall 2.5% for the HICP and for the CPI excluding energy at 2.7% are still excessive.
