BRATISLAVA, Dec 15 (Reuters) - The Slovak economy will contract less than previously expected this year, the central bank of the euro zone's youngest member said on Tuesday, adding that it now also expects stronger economic growth in 2010.
The export-reliant economy, driven mainly by the auto and electronics sectors, has been going through its deepest downturn since independence in 1993, but the central bank is pinning its hopes on a faster recovery in global demand to help it pick up.
The National Bank of Slovakia (NBS) upgraded its forecast for the country's gross domestic product to a contraction of 4.8 percent this year from its previously expected 5.6 percent drop. The finance ministry sees a 5.7 percent contraction.
The bank said in a regular update of its economic forecasts that it saw real GDP growth of 3.1 percent next year, up from a previously forecast 2.9 percent rise.
"It needs to be emphasised that the recovery of Slovakia and the global economy remains fragile," outgoing NBS Governor Ivan Sramko, who is also a member of the European Central Bank's governing council, told journalists.
"We expect foreign demand to be a pro-growth factor also in the coming years," Sramko said, adding that the euro zone's recovery remains crucial for Slovakia.
Peter Sevcovic, head of the monetary policy department at the central bank, said the risks to the bank's economic growth and inflation forecasts were balanced, citing 70 percent of the risks as external.
The bank expects the annual inflation rate at the end of 2009 to be 0.9 percent, which is sees accelerating to 1.2 percent next year.
Sramko reiterated that swift fiscal consolidation is a precondition for a sound recovery, adding that Prime Minister Robert Fico's government should curb the rising fiscal deficit faster than the European Commission expects.
The European Union's executive body has set 2013 as a deadline for Slovakia to narrow its fiscal gap, seen at 6.3 percent of GDP this year, to the EU's official limit of 3.0 percent.
The finance ministry, however, aims to do this a year earlier after cutting the deficit to 5.5 percent in 2010, when Slovakia should emerge from the crisis as the EU's fastest-growing member, based on European Commission predictions. (Reporting by Martin Santa; Editing by Hugh Lawson)
