BRATISLAVA, Sept 21 (Reuters) - The Slovak crown <EURSKK=> lost ground against the euro on Thursday and dealers said regional bearish sentiment stemming from Hungary could push the unit out of its well-established range towards weaker levels. The crown was quoted at 37.450 to the euro as of 0825 GMT, touch from 37.420 late on Wednesday. The currency has been stuck between 37.300-37.500 to the euro in the past week following sentiment on emerging markets as trading lacked domestic impulses. "If the forint weakens, the crown will weaken too. I think that the 37.500 per euro level will be broken today," said HVB Bank dealer Marian Sulko. The forint tumbled more than two percent against the euro since Monday after the anti-government riots triggered by the leak of a tape in which Prime Minister Gyurcsany admits lying to voters to win general election in April. A decision by Japan's Sony to build a 73 million euro new flat-screen factory in Slovakia provided a slight but temporary support for the crown, but negative mood spilling over from Hungary overwhelmed domestic news. The next domestic impulse is expected in the coming weeks from the details of the 2007 state budget, which will show whether the leftist cabinet keeps the country on track to join the euro zone in 2009. ----------------MARKET SNAPSHOT AT 0830 GMT------------------- Crown/Euro <EURSKK=> 37.450 vs 37.420 on Wednesday Crown/Dollar <SKK=> 29.430 bid vs 29.460 5-yr govt bond <SK5YT=RR> yield 5.050/4.850 vs 5.071/4.772 9-yr govt bond <SK9YT=RR> yield 4.960/4.761 vs 4.961/4.761 -------------------------------------------------------------- ((Reporting by Peter Laca, editing by Cheryl Juckes; peter.laca@reuters.com; Reuters Messaging: peter.laca.reuters.com@reuters.net; +421-2 5341 8402)) ` Keywords: MARKETS SLOVAKIA CROWN OPEN
