* Hungary downgrades highlight CEE risks
* Region's political turmoil clouds reforms outlook
* IMF-led bailouts underpinning economies somewhat
By Michael Winfrey
PRAGUE, March 31 (Reuters) - Hopes that international bailouts would put a floor under investor confidence in central and eastern Europe have been chilled this week after Hungary's credit ratings were cut to one notch above "junk" status.
Despite help from the European Union EU and International Monetary Fund (IMF) for EU members Hungary, Romania and Latvia, the region risks a financing meltdown which could spread to neighbouring countries.
That risk has sparked plans for some of the deepest spending cuts since the fall of communism, but with some governments already toppled, doubts persist over how far any state can go in cuts to socially sensitive programmes such as pensions or child benefits.
A rise in global stock markets has helped cushion the region, as it has restored some risk appetite among investors, but analysts warn that if that fades, central and Eastern Europe are in for a jolt.
"If the nascent recovery in global markets runs out of steam, political risk will only add to the renewed downward pressure on the region's currencies," wrote Neal Shearing, an analyst at Capital Economics.
Hungary's forint, the Polish zloty and the Czech crown have eased 2-3 percent against the euro over the past 10 days.
Only Romania's leu has gained in that time following Bucharest's agreement of a 20 billion euro IMF/EU bailout deal.
Since Hungary's prime minister said he would step down on March 21, his successor has urged swift and painful cost-cutting, including a chop to child care allowances, a freeze in family allowances, a tax on minimum wage and scrapping a year-end bonus to pensioners and state workers.
In Latvia, where the cabinet fell following violent January protests, new Prime Minister Valdis Dombrovskis aims to cut state salaries by a fifth, on top of 15 percent already pledged to the IMF.
His aim is to keep the country's budget gap under 7 percent of GDP.
But such pledges face tough public and political opposition and failure to meet IMF-agreed targets could lead to the flow of funds being shut off, as seen in non-EU neighbour Ukraine.
RISING DEFICIT
As much still rests on executing promised spending cuts and reforms, analysts said EU and IMF piecemeal efforts to shore up flagging countries had been effective but only to a point.
They have come in lieu of a wider EU-led package to underpin the EU's eastern flank, although the bloc has doubled a crisis fund for non-euro zone states to 50 billion euros.
Moody's and Standard & Poor's cuts for Hungary and their negative outlooks marked the second such move since Budapest secured a $25 billion bailout last year.
Both Latvia and Romania have been cut to "junk" status by S&P.
At the heart of those assessments is a growing doubt over whether they can finance gaping current account deficits built up over a decade when borrowing from abroad fuelled a boom in imports which outpaced exports.
"This should be a strong wake up call for all political parties to push ahead with desperately needed reforms, as the alternative will be a further strong depreciation of the forint," said Simon Quijano Evans from Calyon unit Cheuvreux regarding Hungary's downgrade.
Collapsing growth has recently narrowed deficits in the Baltics and Balkans as spending especially on foreign goods fell away but no so in Hungary, where an even sharper collapse in euro zone demand for its exports meant the gap widened last quarter.
"That is certainly a concern because Hungary already has a big fiscal gap and a big package from the IMF," said Maya Bhandari, economist at Lombard Street Research. "Its external financing needs are still growing rather than falling. I remain quite concerned about the region as well."
Hungary is expected by many analysts to shrink by more than 5 percent. Latvia's government announced on Monday its economy could contract by almost 15 percent and neighbour Lithuania is braced for a fall of at least 10 percent.
Lombard's Bhandari expects even the region's strongest economy, Poland, to post zero growth at best this year, below the 1.2 percent forecast by a Reuters poll of analysts.
According to Cheuvreux's Quijano Evans, the EU, IMF, and others have now set aside up to 130 billion euros for the region hoping to backstop the stragglers.
"This is clearly addressing the issue very, very strongly," he said. "And the EU is fully behind this."
Last week, the IMF said it had created a new flexible credit line for well-run emerging market countries under which they could tap funds with no strings attached. Analysts say those states could include Poland or the Czech Republic. (Reporting by Michael Winfrey; Editing by Jason Neely)
