BUDAPEST, Nov 30 (Reuters) - Markets in the European Union's eastern states were mostly firmer on Tuesday as Poland reported stronger than expected growth in the third quarter of the year, while investors consolidated after Monday's sharp falls.
But Hungary's auction of three-month debt fell short of its target amount and yields rose after Monday's surprise central bank (NBH) rate increase, and a conflict between the bank and the government also weighed on the forint.
The euro zone debt crisis kept sentiment fragile in the region and currencies are struggling to stay on the firmer side of key technical levels, traders said.
Poland's gross domestic product (GDP) rose by 4.2 percent in annual terms in the third quarter, more than analysts' 3.6 percent consensus forecast.
The zloty <EURPLN=> firmed after the figures, following Monday's falls, strengthening 1.1 percent against the euro to 4.053 by 1058 GMT. Hungary's forint -- the other big loser in the past days -- firmed 0.3 percent to 282.75 in volatile trade.
Romania's leu <EURRON=> firmed 0.4 percent to 4.284, while the Czech crown <EURCZK=> eased 0.1 percent to 24.855.
Hungary's forint <EURHUF=D2> briefly reached the key 285 technical level against the euro before rebounding, even though the government cut its three-month Treasury bill sale to 30 billion forints from 40 billion forints offered.
The NBH surprised on Monday by lifting its base rate by 25 basis points from a record low of 5.25 percent, the first central bank in the region since the 2008 global crisis to increase interest rates. [
]Even though it indicated that further tightening may come, a report that the government may press for a rise in the bank's inflation target -- adding to plans to replace the majority of rate setters next year -- added to concerns over Hungary's policy path.
"Based on that, a weakening forint trend is on the cards," one Budapest-based currency dealer said.
"In the first round, 285 looks a technical support, then 288-290 from which the forint rebounded several times in the past two years, while a move through 290 would be a significant technical breakthrough," the dealer added.
An auction on Thursday of three, five and 10-year bonds <HUISSUE> will be a key test of investor appetite after a recent jump in yields, traders said. Yields on Hungary's 10-year debt rose 11 basis points to 8.43 percent on Tuesday.
"At these levels the interest of foreign investors should grow already, but this will fight with concern over the euro zone at the auction and it's unclear which factor will be stronger," one Budapest-based trader said.
CBANK TALKS UP ZLOTY
The region's stock markets rose, led by a rebound in Budapest where the main equity index <
> gained 2.2 percent.The zloty -- investors' favourite Central European currency in recent months due to strong Polish growth -- rebounded after breaching technical levels at 4.0 and 4.1 in the past week.
"The (Q3 GDP) data is positive for the zloty, although it will mitigate the unfavourable environment rather than turn the trend around," said Rafal Benecki, analyst of ING Bank Slaski.
Central bank governor Marek Belka said the currency's fluctuations were "not dramatic" and that it would return to its appreciation trend after global market turbulence over Ireland's fiscal woes ends. [
]But dealers and analysts said concerns over the debt of other euro zone members could maintain pressure on risk appetite and assets in emerging markets -- including Poland despite expectations for central bank rate hikes in Central Europe.
There are also worries that the Polish government has done little other than rely on growth to bring down a budget deficit set to reach almost 8 percent of GDP this year.
"Poland does not exactly stand out for its exemplary national finances either... markets punish PLN additionally," Commerzbank said in a note on currency markets.
Dealers said the Czech crown could meet support around 24.95 to the euro after breaking the 24.890 level. --------------------------MARKET SNAPSHOT-------------------- Currency Latest Previous Local Local
