German Retail Sales (Sep YY) -2.3% (Prev. -0.4%)

A sharp deterioration in the annual rate from a modest negative to a deeper contraction puts this among the weaker readings in the recent run of German consumption data. German retail sales is a notoriously noisy series, subject to heavy revision and calendar distortions, and single prints of this kind have historically been discounted unless confirmed by the broader consumption complex: GfK sentiment, the consumption components of the PMIs, and the ifo retail climate. The transmission channel runs through the German growth narrative rather than directly through rates, since the ECB reaction function keys off the inflation and activity aggregate rather than one country's high-frequency spending data; sustained weakness in the bloc's largest economy is what has historically shifted the council's risk assessment. The read-across to Bunds and the euro tends to be limited at the front of the curve, with any move fading unless the weakness is echoed in the upcoming German GDP and sentiment surveys. The follow-ons worth noting are the revision pattern on this print and whether the monthly sequence confirms a deteriorating trend rather than a volatile single month.
