PRAGUE, May 6 (Reuters) - Central European currencies fell for a fifth straight day on Thursday, with risk appetite low amid persistent fears Greece's debt crisis could spread, while a surprise rate cut hung on the Czech crown.
Worries the escalating Greek crisis could spread to other euro zone periphery states like Portugal or Spain have shaken central Europe's main reference currency the euro and European stocks, and pushed central European policymakers to move more cautiously on interest rates and bond issuance.
Central Europe has been hit by selling of riskier assets despite lower debt piles and better growth outlooks than the rest of the continent.
Currencies were off early morning lows by midday on Thursday but dealers see little relief until signs the euro zone's debt battle is contained.
"We have come quite far in a very short period and are ripe for some profit-taking," a Stockholm-based central European currency dealer said. "This isn't over. Investors are fearful (of contagion) and some may be on the sidelines for some time."
The Hungarian forint <EURHUF=> wiped out half of its early losses to move off a six-month low, bidding 0.5 percent down on the day at 279 to the euro by 1210 GMT.
The Polish zloty <EURPLN=> lost 0.4 percent after earlier touching a new three-month low. It has led losses in the region, dropping 6 percent in a month.
The crown <EURCZK=> fell as much as half a percent following an unexpected cut in Czech rates to a new all-time low of 0.75 percent, but the currency then recovered half that loss. It bid down 0.2 percent from Wednesday's close at 26.046 per euro.
Markets had priced out any chance of a rate cut this week after the crown lost 2 percent in the Greek market turmoil. Analysts had also expected no change, but said the bank likely was influenced by a tame inflation outlook.
"After the Greek problems escalated and the crown weakened, we did not expect a cut," said Pavel Sobisek, chief economist at UniCredit in Prague. "The risk of this decision is the crown exchange rate destabilises."
Analysts said the crown could become more of a funding currency once market jitters ease. The Czech benchmark interest rate was now a quarter point below the euro zone rate.
CAUTION Romania cut rates to a new low of 6.25 percent on Tuesday and warned of risks from fiscal policy and the Greek crisis. Central bank Governor Mugur Isarescu said on Thursday there was now less room to cut rates. [

Czech Finance Minister Eduard Janota was quoted on Thursday as saying the market turmoil may limit foreign bond issues to 28 percent of total Czech government issuance.
But the finance ministry later denied the figure and said its plan was still foreign issuance of up to 50 percent of the total. [
