PRAGUE, Sept 22 (Reuters) - The Czech government approved the 2009 central state budget draft on Monday looking for a sharply lower deficit next year but warned that a dimming economic outlook may force spending cuts.
Finance Minister Miroslav Kalousek told a news conference that in view of the latest global market turbulence and a pending economic slowdown, he considered the ministry's macroeconomic forecast on which the budget is based as "overly optimistic".
The ministry expects GDP growth at 4.8 percent next year, above the central bank's forecast of 3.6 percent. It sees inflation falling to 2.9 percent from this year's 6.5 percent.
"If the data (indicates) that we will not reach our revenue target, the government would freeze some operating expenses in such an amount that guarantees fulfilling the deficit goal," Kalousek said.
He said the changes could be made at the end of this year, after the budget is approved by parliament. The cabinet opted to make no changes at this point because it required by law to submit the budget to the lower house by the end of September.
Monday's draft provides for the central government budget deficit to fall to 38.1 billion crowns ($2.32 billion) next year from 71.34 billion already approved for this year.
The Finance Ministry had said it expects this year's gap to narrow to 58.3 billion crowns.
Next year, the government sees spending up 3.6 percent to 1,152 billion crowns, with revenues at 1,114 billion.
The government aims to keep the total public sector deficit, which also includes off-budget infrastructure funds, regional government budgets and health insurance and other items, at 1.6 percent of gross domestic product in 2009, compared with 1.5 percent this year.
That is comfortably below the EU's ceiling of 3 percent.
SLOWDOWN WOULD HIT REVENUE
Analysts said the government was exposed to an economic slowdown, already indicated by weak order books at industrial firms that are the backbone of the central European economy.
In addition to sagging foreign demand, domestic demand has slowed due to an inflation spike, and exporters in an economy highly dependent on trade have been hit by sharp firming of the crown currency.
"The government could face a problem to meet its deficit targets due to the lower expected growth," said David Marek, an analyst at Patria Finance.
Kalousek said he estimated that a 1 percentage point slowdown in growth would cause a 10 billion crown ($607.9 million) shortfall in the budget revenues.
The country has seen three years of more than 6 percent growth. But in the second quarter this year, GDP growth eased to 4.6 percent and is expected to falter more in the rest of the year.
The centre-right cabinet, which lacks a parliamentary majority, may face hurdles passing the budget draft into law.
Deputy Prime Minister Jiri Cunek said on Sunday that the government should quit if it fails to push the budget draft through. (Editing by Stephen Nisbet)
