Ifo is an acronym from Information and Forschung (research). Published by Munich's Ifo Institute, the Business Climate Index is closely watched as an early indicator of morale in German industry. In addition to overall gauge of sentiment, data are provided on its two components, current conditions and expectations. As a forward looking indicator, the latter is normally seen as the more important. Ifo surveys more than 9,000 enterprises in manufacturing, services, construction, wholesaling and retailing and a separate estimate of sector confidence is supplied for each.

The headline index has a good correlation with developments in overall GDP and so has a major influence in shaping views on how the national economy is performing. The main focus is the expectations index.
