WARSAW/PRAGUE, May 6 (Reuters) - Central Europe's currencies mostly fell back on Wednesday after a rally ran up against a wall this week, but the Romanian leu held steady after a surprise half percentage point interest rate cut.
Currencies have jumped over the past month along with improving sentiment for emerging markets, with the Hungarian forint nearing a 3-1/2 month high this week and the leu touching a three-week peak.
But investors have turned cautious in the run-up to stress test releases on U.S. banks later this week and as data in central Europe points to tough economic times ahead. Central European bourses, though, bucked the trend to gain more than 1 percent.
Romania's central bank cut interest rates more than expected by 50 basis points on Wednesday over worries of a falling economy, winning some breathing space after a 20 billion euro IMF-led aid package last month. [
]The leu <EURRON=> edged up 0.1 percent to 4.153 to the euro.
"The decision is largely because the IMF made available foreign currency support," said Barbara Nestor of Commerzbank in London. "It is more likely to see the currency stabilising, despite the rate cut, because the IMF impact is much stronger."
But other currencies fell, led by the Polish zloty <EURPLN=> with a 0.9 percent fall on the day, bidding at 4.408 against the euro by 1345 GMT.
The Hungarian forint <EURHUF=> fell to 284.55 to the euro, down 0.3 percent, and the Czech crown <EURCZK=> dropped 0.7 percent to 26.797 per euro.
"There are concerns about these U.S. stress tests (on banks) which did create a weaker backdrop for emerging Europe today," said UniCredit emerging strategist Martin Blum.
"The bottom line is a lot of these eastern European currencies had rallied quite significantly in the previous few weeks, and I think at these levels... it will prove increasingly difficult to drive eastern European currencies stronger."
GOOD DEBT
The zloty and Hungarian forint have led gains with almost 4 percent rises since April 27. Romania's leu has gained 1.4 percent in that time.
Central European debt continued to get strong investor demand, with Poland selling 766 million zlotys worth of bonds at a switch tender on Wednesday. [
]In the Czech Republic, demand stayed solid at the first domestic auction since selling a euro-denominated bond on international markets last week. [
]Hungary's debt agency bought back fewer bonds than in previous weeks ahead of a debt auction on Thursday.
"The repurchases are losing steam as the auction showed," a trader said. "Tomorrow's (bond sale) auctions will provide the market with some indications about the future."
Darker economic outlooks in central Europe, widening fiscal gaps and easier monetary policies are set to keep pressure on currencies in coming months, although strategists don't expect the wide swings seen earlier this year that sent units crashing. ----------------------MARKET SNAPSHOT------------------------- Currency Latest Previous Local Local
