Italian CPI Final (Aug MM) 0.5% vs. Exp. 0.5% (Prev. 0.3%)

The information content sits in the revision risk and in the month-on-month acceleration versus the prior reading, which in episodes of firming sequential momentum has fed through to the core debate at the ECB only if the larger member states print in the same direction. Italian inflation data matter for the BTP complex chiefly through the euro HICP aggregate and through any signal on services stickiness, the component that has historically dominated the ECB's reaction function late in a disinflation. Divergence between Italian and German or French prints has in past cycles been a slow-burn widening factor for the BTP-Bund spread rather than a headline-driven one. The follow-ons are the euro-area flash aggregate, the detail on core and services within this release, and whether national prints collectively shift the expected path at the front of the euribor curve.
