The increase took analysts by surprise -- consensus forecasts had the January index remaining stable at around 99.7 points.
"After already
improving sharply in recent months, the business climate index rose
sharply again in January," said Ifo chief Hans-Werner Sinn. "Any doubts
people might have about the strength of the current upturn, underway
since last summer, will be further diminished by these numbers. The
upward trend is gaining in strength and breadth."
Analysts were pleased by the numbers.
