BUCHAREST, May 20 (Reuters) - Central European currencies resumed weakening on Thursday afternoon due to regulation fears in the euro zone, but the zloty recovered part of the losses as market sources said Polish state-owned bank sold euros.
Investors were worried other European countries may announce regulation measures following Germany's ban on naked short selling of some assets on Wednesday and went searching for safer havens.
Renewed risk aversion meant currencies and stocks quickly gave up gains made in choppy morning trade.
At 1344 GMT, the Polish zloty <EURPLN=> led losses with a 1.4 percent fall, the Hungarian forint <EURHUF=> was 0.2 percent lower, the Czech crown <EURCZK=> was 0.3 percent weaker and the Romanian leu <EURRON=> was flat.
Stocks also fell 2-3 percent and yields were higher.
"It's just a flight from risk," said one dealer in Warsaw.
The zloty pared some of the losses as two market sources told Reuters Poland's BGK bank sold euros on the spot market after the unit had fallen about 2 percent.
The finance ministry and the bank both declined comment on the reports. However, the ministry reiterated it may use sharp zloty falls to sell euros [
].The zloty was unaffected by April producer prices and industrial output data, which came slightly below expectations. Analysts said Thursday's data did not alter their expectations that the central bank will leave interest rates unchanged for the time being. [

ROMANIA TENDER SURPRISES
Despite the risk aversion, the region's debt tenders drew hefty demand as investors see central Europe's debt picture as better than parts of the euro zone.
Hungary sold 50 billion forints worth of government bonds with demand almost double the amount on offer and with lower yields for the three- and five-year paper. [
]Romania also saw big demand for its 10-year bond tender when it sold all the planned amount of 700 million lei at a slightly lower yield, despite market expectations the government would reject all bids.
Dealers suspect Romanian state-owned banks snapped up the paper, doubting foreign investors played much of a role given uncertainty over the government's ability to enforce austerity measures. [
]The six-old month centrist cabinet has committed to drastic cuts in wages and pensions, but markets fear it will bow to mounting social pressure after tens of thousands of people rallied in central Bucharest on Wednesday.
The IMF deal is the main anchor for investors willing to finance Romania's ballooning budget deficit.
"I'm very surprised," said Vlad Muscalu, an economist at ING Bank in Bucharest. "One thought is that state-owned banks have bought at this yield, another is that pension funds had unexpected demand."
"But this is very strange ... it does not match the secondary debt market or neighbouring debt markets."
In Romania's dormant secondary market, a relatively active 5-year bond was trading on Thursday at a yield of 7.45 percent, compared with an average accepted yield of 7 percent at the 10-year auction.
Auctions for 10-year paper have been rare and the ministry has usually sold less than planned. --------------------------MARKET SNAPSHOT-------------------- Currency Latest Previous Local Local
