Divergence in Goods and Services Inflation: Implications for Core Inflation and the Outlook

The services sector is still thriving, however, and enjoying the post-pandemic shift from goods to services. Services most affected by lockdowns are currently experiencing much faster price growth than other services or goods. While the upcoming summer holiday period could still fuel service price inflation, we did see a decline last month. The drop was largely due to cheaper public transportation tickets in Germany, however, so it seems too early to call a significant improvement in services inflation just yet. Finally, services inflation traditionally shows a much stronger correlation with wage growth than goods inflation. With wage growth trending up and probably coming in at around 5% year-on-year in the eurozone, services inflation remains the largest problem for core inflation and the ECB.

 

Still, a key question remains over how long the divergence between goods and services inflation can last. Historically, we don’t see much evidence of an extended difference between the two. Goods inflation typically leads services inflation by approximately six months, which means that the peak in the former from February suggests that the latter is unlikely to remain elevated for the rest of the year. If we are right and the post-pandemic shift ends after the summer holiday period, we could see services inflation starting to come down before the end of the year.

Core inflation set to trend down from here on out

While services inflation continues to see some upside risk for the months ahead, core inflation overall looks set to trend down on the back of slowing goods prices. Even services inflation could already be trending down, but perhaps not as fast as policymakers would like it to. When looking at selling price expectations for sectors that sell most to consumers, we see that there has been a steady downturn in the number of businesses intending to raise prices. This generally correlates fairly well with core inflation developments seven months later, which would point to a significant slowdown in the core rate.

At the current juncture, experts and central bankers will be hesitant to make an outright call for a sharp drop in inflation. The latest track record of inflation forecasting is simply not on their (or our) side. Nevertheless, as much as it was once obvious that the era of low inflation had to end at some point, it's now clear that the short period of surging inflation will also cease sooner or later. Historical evidence and the latest developments in both goods and services give enough comfort to expect both headline and core inflation to decline.

We currently expect core inflation to drop below 4% at the end of the year and for it to fall to 2.5% by mid-2024. The risks to that outlook seem to be fairly balanced, with more stubborn core inflation on the back of faster wage growth and a faster drop on the back of weak goods inflation both decent possibilities.
