The basic news analysis of the recent German inflation report is that it confirms the preliminary report showing that inflation broke lower, as it did in October. In October, the HICP for Germany fell by 0.2%; the core rose by 0.1%; the domestic gauge showed headline inflation at -0.2%, with the CPI ex-energy flat. These four metrics constitute a good inflation report for Germany on the month. Prices fell month-to-month for food, clothing & footwear, transportation, and recreation & culture.
Sequential inflation HICP However, if we look at sequential trends, a slightly broader look at inflation over 12 months, six months, and three months, we find a slightly different narrative on German inflation. The HICP shows inflation at 2.8% over 12 months, easing to 2.7% at an annual rate over six months and to 2.6% at an annual rate over three months. That’s a clear progression lower and also a very slow progression lower. The core HICP is up 2% over 12 months, up at a 2% pace over six months, and at a 1.6% annual rate over three months. Again, this is a very good sequence of numbers, with the core basically hewing to the pace sought by the European Central Bank and then a three-month growth rate that dips well below it.
Sequential inflation using the domestic gauge The German domestic CPI shows 12-month inflation at 2.8%, decelerating to a 2.1% annual rate over six months, then springing back up to 2.9% at an annual rate over three months, showing a higher inflation rate over three months than over 12 months—goodbye, inflation progress. The domestic CPI excluding energy is up 1.9% over 12 months, about a 2% pace over six months, and up at a 1.6% annual rate over three months. The ex-energy metric continues to perform in line with the ECB guidelines and produces an even weaker inflation rate over three months. So, there is still good news—but mixed news—in the domestic CPI.
Optimism confirmed On balance, there is good reason to be optimistic about German inflation. The October number was strikingly positive good news, and the three-month annual rate, at least for the core or ex-energy versions, is a stellar result. However, if we try to trace this through diffusion statistics, what we see is that inflation diffusion over 12 months is at 45.5%. While that's good news, a diffusion metric at 50% shows as much acceleration as deceleration across categories. So, readings above 50% show relatively more acceleration and readings below 50% show relatively more deceleration. The 12-month inflation rate shows more deceleration over 12 months than there was 12 months ago, but by a small increment. The six-month inflation diffusion metric is also at 45.5%, and this compares six-month inflation to 12-month inflation. Over the three months, however, the diffusion metric is at 63.6%, showing that inflation over three months has suddenly moved up broadly, even though the inflation rate itself remains contained for the core. It is high for the headline, but the diffusion or breadth reading is something that goes across all categories. So, this finding is not confirming the good three-month inflation results.
Encouraging with a caveat German inflation data are certainly encouraging. The uptick in breadth for inflation is something that's somewhat worrisome. But on a monthly or quarterly basis, inflation numbers are almost always going to produce at least one uncomfortable metric when you're trying to assess inflation prospects. Brent, measured in euros, is up by 76% over 12 months; over three months compared to six months, it shot up by 200%.
