BRATISLAVA, Oct 6 (Reuters) - Slovakia's new centre-right government approved on Wednesday the 2011 state budget draft, aiming for the largest budget consolidation among the European Union's ex-communist east.
The draft, to be debated by parliament in the coming weeks, is designed to cut the overall gap to 4.9 percent of gross domestic product (GDP) from about 7.8 percent this year through a combination of spending cuts, tax hikes and a small contribution from economic growth.
The euro zone periphery country's consolidation plan is much more ambitious than deficit cuts planned by other central European countries, albeit coming from a worse balance.
"Next year will be tough, when most of the consolidation will be done...a low deficit is a necessary precondition for a healthy economy," said Finance Minister Ivan Miklos.
"Next year, Slovakia will have to borrow 8 billion euros. We had to prepare a budget that will convince investors.. so we can borrow cheaply," he said.
He said the consolidation amounted to 2.5 percentage points, excluding a half-a-point contribution of economic growth predicted to slow down to 3.3 percent from 4 percent expected this year.
The cabinet introduced a 1.75 billion euro austerity package in September aimed at cutting spending and boosting budget revenue.
Slovak unions plan a protest against the savings next week, part of a wider discontent by European unions with budget cuts across the continent.
Slovakia's debt has jumped during the economic slowdown to 43.8 percent of gross domestic product this year from 27.7 percent at the end of 2008. The government expects it to peak at 47.3 percent in 2012, a figure roughly around half the European average.
Prime Minister Iveta Radicova's cabinet holds a narrow majority in the parliament but looks set to comfortably win support for its budget proposal.
The euro zone's poorest member pledged to cut its fiscal gap to below the European Union's official cap of 3 percent of GDP by 2013 and seeks to reach a balanced budget in the mid-term.
The approved budget draft carries significant risks related to the global economy recovery, impacts of Slovakia's austerity measures and fiscal discipline of local authorities.
The neighbouring Czech Republic approved its 2011 budget last month with a 4.6 percent fiscal deficit ceiling, while Poland's gap should stand at 5.0 percent in 2011 according to Polish accounting methodology.
Alongside approving the budget, Slovakia opened the books for a 2 billion euro eurobond on Wednesday, and demand reached more than 4 billion by mid-day, the country's debt agency said.
Miklos said the expected pricing at 150 basis points above mid-swaps would be a success and a vote of confidence in the Slovak fiscal plans.
