Why it matters
Confidence leads hiring and investment decisions, so these surveys often turn before the hard data. Germany's Ifo and ZEW, and Japan's Tankan, are among the most market-moving releases for the euro and the yen.
How it is calculated
Survey answers (better/same/worse) are turned into a balance (positive minus negative answers) or an index around a long-run average of 100; the release separates current conditions from expectations.
What changes mean
- The expectations component turns first; watch its direction over several months.
- A gap between strong current conditions and weak expectations often marks a peak.
Higher than expected: A stronger figure than expected points to a healthier economy: it usually supports the Australian dollar and local stocks, and can push bond yields up.
Lower than expected: A weaker figure than expected points to slowing activity: the Australian dollar tends to soften and markets price in lower rates.
A short history
Business tendency surveys began in Germany (Ifo) and other European countries after the Second World War; the Bank of Japan's Tankan has been run for decades, and the ZEW financial-expert survey since 1991.
