* Cen banks say currency falls not backed by fundamentals
* Currencies jump, forint up to 3.6 pct on the day

PRAGUE/BUDAPEST, Feb 23 (Reuters) - Central Europe's central banks took the unprecedented step of joint verbal intervention to support the region's currencies on Monday, saying a sharp drop in recent months did not reflect economic fundamentals.
Hungarian policymakers also left interest rates unchanged, and central bankers from Budapest, Prague, Warsaw and Bucharest all came out to say the currency falls in the past few weeks had been overplayed. Economists, however, said they would probably have to back up their talk with action.
The coordinated move boosted units across the region. The Czech crown <EURCZK=>, Hungarian forint <EURHUF=> and Polish zloty <EURPLN=> each jumped around 1 percent against the euro after the comments, adding to earlier gains.
"It is a fact that coordination at present is more intensive than at other times and that we share the opinion that the currency swing in a number of countries does not correspond to the real economic situation," Czech central bank chief Zdenek Tuma told Reuters in a an interview.
"We agreed in this respect that we will comment on the development in a similar way and of course we will further continue in a more intensive communication than usually."
Central European markets have been battered in the past few weeks as investors worried about the countries' exposure to foreign currency debt and a slump in exports as the global financial crisis swept into the region.
Their banking systems, in some cases dependent on external financing, have raised worries over their ability to ride out the currency drops and tight external financing.
The zloty and forint are still down 10 percent for this year against the euro, with the Polish currency having lost about a third of its value since last July. The leu is down 6.1 percent, and Czech crown 4.6 percent.
In Poland the weakness has particularly hit firms that bet wrongly against the euro when the zloty was strong last year. Polish and Hungarian borrowers who took out mortgages and other loans in currencies such as the Swiss franc and the euro have also suffered because their debt has mushroomed as their home currencies fell.
WORDS NOT ENOUGH A number of policymakers and states including Austria -- whose banks are heavily exposed to central and eastern Europe -- and British Prime Minister Gordon Brown have called for aid to the region.
Analysts said action would have to follow the verbal intervention to stop the currencies' slide.
"This is of course a clear signal that the CEE central banks are very concerned about the situation and will try to curb the selloff in the currencies," said Lars Christensen, head of emerging markets research at Danske Bank.
"We doubt that verbal intervention is enough and the central banks in the region might need to hike rates -- or get outside help for example from the ECB (European Central Bank). That said, this should at least in the short-term give some relief to the CEE currencies."
Polish central bank chief Slawomir Skrzypek said his bank could take unspecified action to reverse the zloty's fall.
"In the central bank's view, the macroeconomic situation of Poland does not justify such a scale of zloty weakening," he said in a statement. "The central bank can undertake action in order to avoid the negative impact of zloty volatility on the economy."
Coordination with other central banks in the region may raise the effectiveness of central bank actions, he added.
The Hungarian central bank left rates flat at 9.5 percent on Monday after 200 basis points in cuts since an emergency 300 basis point increase last October. Governor Andras Simor said a worse risk assessment of Hungary was a factor in the decision.
In Romania, central bank Governor Mugur Isarescu said the bank was ready to act against destabilising currency moves. [
