Disinflationary Trend in the Eurozone: Spotlight on Core Inflation

The disinflationary trend in the eurozone has started and should gain more momentum after the summer. It will take a while but core inflation should follow suit as well.
Slowly but surely, the inflation outlook for the eurozone is improving. Base effects as well as fading supply chain frictions and lower energy prices have and will continue to push down headline inflation in the coming months – a drop that the European Central Bank deserves very little credit for orchestrating. With headline inflation gradually normalising, the big question is how strong the inflation inertia will be. As long as core inflation remains stubbornly high, the ECB will continue hiking interest rates. How long could this be?
Inflation is moving in the right direction, but will core inflation remain stubborn?
Headline inflation has come down sharply, which is widely expected to continue over the months ahead. The decline in natural gas prices has been remarkable over recent months and while it would be naïve to expect the energy crisis to be over, this will result in falling consumer prices for energy. The passthrough of market prices to the consumer is slower on the way down so far, which means that there will be more to come in terms of the downward impact on inflation.
The same holds true for food. Food inflation has been the largest contributor to headline inflation from December onwards, but recent developments have been encouraging. Food commodity prices have moderated substantially since last year already, but consumer prices are now also starting to see slow. In April and May, month-on-month developments in food inflation improved significantly, causing the rate to trend down.
Headline inflation – at least in the absence of any new energy price shocks – looks set to slow down further, but the main question now is how sticky core inflation will remain. There are several ways to explore the prospects for core inflation.
Let’s start with the historical relationships between headline and core inflation after supply shocks. Data for core inflation in the 1970s and 1980s are not available for many countries, but the examples below for the US and Italy show that an energy shock did not lead to a prolonged period of elevated core inflation after headline inflation had already trended down. In fact, the peaks in headline inflation in the 1970s and 1980s saw peaks in core inflation only a few months after in the US and coincident peaks in Italy. We know that history hardly ever repeats, but it at least rhymes – and if this is the case, core inflation should soon reach its peak.
History is one thing, the present another. Digging into the details of current core inflation in the eurozone shows a significant divergence between goods and services, regarding both economic activity and selling price expectations. Judging from the latest sentiment indicators, demand for goods has been weakening for quite some time already. At the same time, easing supply chain frictions and lower energy and transport costs have taken away price pressures, leading to a dramatic decline in the number of businesses in the manufacturing sector that intend to raise prices over the coming months.
