VIENNA, May 11 (Reuters) - Foreign direct investors in emerging Europe became more cautious in their outlook for the region, and the upwards trend in business morale slowed down for the second quarter, a survey showed on Tuesday.
The Thomson Reuters & OeKB Central and Eastern European Business Climate index <REUTERSOEKB> rose in Russia, Poland and some Balkan countries, but the rate of improvement slowed down markedly from last year's turnaround. [
]The quarterly index rose to 21 in April from 16 in January, sectorally driven by a marked improvement of sentiment among real estate investors and transport companies, while it edged down among banks and insurers.
Panelists were "significantly more happy with their current business situation than they were in January", said Austrian export financing bank OeKB, which compiled the survey from replies gathered between April 6 and 26.
"But the new spirit of optimism that emerged among foreign investors in the second half of 2009 didn't fully hold in 2010," it said. "The investors see the future optimistically, but show overall more caution."
The index's indicator for companies' assessment of their current business situation rose to 10 from 3 in January, while business expectations expanded to 33 from 29. The view of the broader economic outlook improved most, to 31 from 19.
"On a country level, the differences are significant. While especially in Russia, the economy will step up a gear, Croatia is still mired in financial and economic crisis, which hit the country belatedly," OeKB said.
BUMPY ROAD TO TURNAROUND
Eastern European countries -- with the notable exception of Poland -- went into a sudden and sharp recession last year as demand from western Europe for their exports collapsed and bank lending froze in the global financial crisis.
The International Monetary Fund in April raised its forecast for east Europe's growth this year, but cut its 2011 outlook, noting that recovery in the region would be the slowest among the world's emerging economies.
East Europe is struggling to contain rising unemployment and many analysts forecast a slowdown that will follow the end of euro zone stimulus programmes like Germany's car-scrapping scheme and an end to inventory restocking.
While the business mood in Hungary turned positive, Ukraine was the only country where it remained negative and was even worse than three months earlier.
NOTE - Distributed exclusively on the Reuters System, the Thomson Reuters & OeKB Central European Business Climate Index is based on quarterly surveys of 400 international companies with regional headquarters in Austria, which manage 1,400 affiliate companies in 19 countries in central and eastern Europe.
