INSEE put France at 3.1% on its final figure. Should a national print move your euro view before the total?

INSEE's final figure put French consumer price inflation at 3.1% on the year in September, up from 2.4% in August and above the 3.0% provisional estimate (France report). Germany's final figure was 3.3% (German report), and the euro area's was 3.8% (euro area report).

The national figures arrive first, and the aggregate arrives later. So by the time the euro area number is out, traders have already seen the big countries.

We would like to hear how you use national data:

• Do you trade the national inflation releases, or only the euro area aggregate?
• Which country do you check first, and do you weight them by size?
• Does a national surprise move EUR/USD for you, or only the aggregate?
• Have you been caught out by a national figure that did not show up in the euro area total?

How inflation moves currencies explains why inflation matters for the euro.

France's final figure came in above its provisional estimate, while Germany's confirmed figure matched its provisional one exactly. A revision in one direction across several countries would carry more information than a single change. Do revisions of this kind change how you weigh the first print?
