Germany's Ifo institute said its business climate index, based on a survey of 7,000 executives, fell to 101.4 in September from 102.3 in August. Polls of economists by both Bloomberg News and Reuters had forecast an increase.
"There's no magic bullet to this European crisis," Hayes Miller, head of asset allocation in North America at Baring Asset Management, told Bloomberg. "The politicians have been trying to put on a face of unity. Yet there are no easy solutions. You're going to have an economic growth rate that's going to be quite poor over the next year. It's going to be a challenging environment."
Indeed, International Monetary Fund chief Christine Lagarde foreshadowed the fund might soon lower its estimates for global economic growth.
"We continue to project a gradual recovery, but global growth will likely be a bit weaker than we had anticipated even in July, and our forecast has trended downward over the last 12 months," Lagarde said in a speech at the Peterson Institute for International Economics in Washington, DC.
In late afternoon trading in New York, the Standard & Poor's 500 slipped 0.08 per cent. The Dow Jones Industrial Average eked out a 0.06 per cent gain.

Finding favour with investors, however, were shares of Google, which climbed to a record, amid optimism over the search engine's outlook. Shares were last up 2.1 per cent at US$749.70, after earlier rising as high as US$749.87.
"The markets have to come to appreciate that Google's been making money hand over fist all this time," Brian Wieser, an analyst at Pivotal Research Group, told Reuters.
