BRATISLAVA, Oct 3 (Reuters) - The Slovak crown <EURSKK=> broke its 37.300 resistance level to the euro on Tuesday on the back of investors boosting positions, and dealers said there was room for more gains in the short run. The crown stood at 37.255 to the euro as of 0900 GMT, 0.3 percent up from 37.375 late on Monday. "There's a chance the crown could go firmer, there is no negative influence on it right now," one Bratislava-based foreign trader said. The currency has hugged a narrow range of 37.300-37.500 to the euro for days, shrugging off a central bank rate hike last week, while mirroring regional swings dictated by political jitters in Poland, Hungary and the Czech Republic. ----------------MARKET SNAPSHOT AT 0900 GMT------------------- Crown/Euro <EURSKK=> 37.255 vs 37.375 (+0.32 pct) on Monday Crown/Dollar <SKK=> 29.255 vs 29.320 (+0.22) 5-yr govt bond <SK5YT=RR> yield 4.693/4.392 vs 4.709/4.411 9-yr govt bond <SK9YT=RR> yield 4.528/4.328 vs 4.558/4.357 -------------------------------------------------------------- ((Reporting by Martin Santa, editing by Stephen Nisbet; martin.santa@reuters.com; Reuters Messaging: martin.santa.reuters.com@reuters.net; +421-2 5341 8402)) Keywords: MARKETS SLOVAKIA CROWN OPEN
