HICP Trends- Italian inflation fell by 0.2% in June; its core elevated by 0.4% month-to-month. Sequentially, headline inflation paces at 6.7% over 12 months, that falls to a very skinny 0.3% over 6 months, and then expands sharply to register an annualized gain of 5.5% over 3 months. The headline figure has been quite volatile. However, core inflation is up by 6.1% over 12 months, up at a 5.3% annual rate over 6 months and at a 4.3% annual rate over 3 months. The core rate shows sequential deceleration in the face of headline inflation turbulence.
Domestic inflation trends- Italy's domestic CPI follows the same pattern as the EMU-wide harmonized gauge (HICP) for its headline and core. The headline for domestic inflation rises 6.4% over 12 months, falls sharply on a 0.8% annual rate increase over 6 months, and then rises back to a 4.1% annual rate of change over 3 months. The domestic Italian CPI excluding food & energy shows sequential deceleration like its HICP counterpart. It rises at a 5.6% pace over 12 months, slides to a 4.8% pace over 6 months, and logs a 4.0% annual rate over 3 months. The HICP measure and the Italian domestic measure of inflation are giving the same signals about inflation. Headline inflation has been high and volatile and has had some bounce back over the last three months, while core inflation, undeterred, continues to edge down. But core inflation is still running at a rate of 4% or more over the last 3 months. Its pace over 12 months, on the other hand, a pace that that the ECB pays more attention to, is still in the area of 5 ½ percent to 6 ½ percent.
Acceleration/deceleration trends are mixed- The table provides evidence on inflation’s acceleration and deceleration over 3 months, 6 months, and 12 months. Over 3 months compared to 6 months, gauging acceleration across categories, inflation is accelerating in half the categories (diffusion = 50%). Over 6 months compared to 12 months, inflation accelerates in only about 42% of the categories. Over 12 months compared to 12-months ago, inflation accelerates in 83% of the categories. Looking at the data in the table, the year-on-year acceleration figure seems high considering that the HICP headline and the domestic CPI headline both show increases on the order of 6 ½ percent or so over 12 months compared to gains of over 8% a year ago. If inflation is so much lower now, why is diffusion higher in comparison? Looking at the core inflation rates, we find the answer: the year-ago HICP core inflation was 4.1%; over the last 12 months the core inflation rate is 6.1%; a year ago the domestic core rate was at 3.8% and over the last 12 months is 5.6%. So, while the headline gauges have decelerated, it’s the core rates that are accelerating and reflected in the diffusion index.
Quarter-to-date inflation- The quarter-to-date data reflect the finished second quarter. Inflation in Q2 logs in at a 2.8% annual rate increase for the headline and a 3.8% annual rate increase for the core in the HICP. Domestic inflation on the Italian gauge has a headline gain of 2.4% with the core much hotter at a 4.7% annual rate increase.
