The fourth-quarter SPF reports respondents’ forecasts. Its fieldwork window matters when comparing the results with subsequent policy decisions and economic releases.

What the primary record establishes

The ECB published its fourth-quarter 2026 Survey of Professional Forecasters results on 30 October. The survey ran on 2–7 October and received 52 responses. ECB — Survey of Professional Forecasters, 30 October 2026 ↗

Respondents put 2027 headline inflation at 2.6%, 0.4 percentage point above the previous round. The release explicitly separates their views from those of ECB decision-makers and staff. ECB — Survey of Professional Forecasters, 30 October 2026 ↗

What the distinction changes

WFN interpretation: publication date is not the date on which every forecast was formed. Treating this survey as a reaction to the ECB’s 29 October meeting would reverse the order of the information flow.

For an honest comparison, keep the fieldwork window beside the release timestamp and the forecast horizon. That makes a later disagreement understandable without assuming that respondents ignored information not yet available to them.

What to check before drawing a conclusion

A change of 0.4 percentage point is also different from a 0.4% relative increase. Record the unit of a revision separately from the level to prevent small-looking labels from changing the meaning.

Compare later forecasts at the same horizon and identify whether changes reflect new information or a different sample. This survey documents expectations, not realised 2027 inflation or an official promise about interest rates.
