German business confidence hits eight-month high in March

German business confidence rose to its highest level in eight months in March, as optimism continues to grow about the outlook for Europe's biggest economy, the Ifo economic institute said Wednesday.

The Ifo institute's closely watched business climate index rose to 107.9 points this month, its highest level since July 2014, the think tank said in a statement.

It was the fifth consecutive monthly increase and was better than analysts had been expecting.

"Companies were more satisfied with their current business situation. They also expressed far greater optimism about future business developments," said Ifo president Hans-Werner Sinn. "The German economy is continuing to expand."

Ifo calculates its headline index on the basis of companies' assessments of current business and the outlook for the next six months.

The sub-index measuring current business rose to 112.0 points from 111.3 points, while the outlook sub-index increased by 1.4 points to 103.9 points, the institute said.

Analysts said the Ifo reading confirms that the German economy is already shrugging off the geopolitical uncertainty that depressed sentiment last month.

"Companies are shaking off worries about Russia and Greece, which had been weighing on optimism in February," said Berenberg Bank economist Christian Schulz.

"Further improvements in Germany's momentum are ahead. The economic tailwinds of cheap oil and a weaker euro take time to feed through to companies' and households' purchasing and investment decisions," Schulz said.

The Ifo index is still a long way from reflecting a real "boom", "but the upswing is broad-based," the expert noted.

Natixis economist Johannes Gareis similarly believed that the Ifo data "add to the bright picture of Germany's economic outlook."

German business confidence "has clearly left behind its lull in mid-2014, strengthening the case for optimism about Germany's growth prospects," he said.

Postbank economist Heinrich Bayer said the rise in the Ifo index offered a "clear signal that the economy upturn will continue in the coming two quarters."

"Optimism has returned to the German economy," concurred ING DiBa economist Carsten Brzeski.

"Strong growth in the fourth quarter of 2014, combined with low energy prices and the weak euro exchange rate, have boosted confidence in the economy."

The European Central Bank's bond purchase programme was also a factor driving optimism, Brzeski said.

"The economy is like a sailboat which only needs to hoist the sail and lean back to relax. Strong tailwinds could bring the strongest economic performance since 2011," he said.
