* Zloty hits new 1-mth high as state-owned bank sells euros
* EUR/PLN pushed lower ahead of final fixing for debt level
* Crown up 0.1 pct, breaks through 200-day moving average

WARSAW, Dec 31 (Reuters) - The Polish zloty hit one-month highs on Friday on buying by a state bank designed to keep government debt levels within legal limits, while other currencies in the region tracked the euro higher.
Market participants had expected the Polish finance ministry to try to support the zloty through state-owned bank BGK ahead of a Dec. 31 fixing that determines the level of this year's public debt. A quarter of the country's debt is denominated in foreign currencies.
Under Polish law, if debt breaches 55 percent of gross domestic product (GDP), the government is required to make painful spending cuts, something it especially wants to avoid before parliamentary elections due next autumn.
"BGK is hitting bids hard to push the final fixing lower," one Warsaw-based dealer said. Two other FX dealers in Warsaw confirmed the presence of BGK on the market.
The bank and the finance ministry declined to comment.
At 1137 GMT the zloty <EURPLN=> was trading up 0.2 percent versus the euro, a touch off highs of 3.948, with the highest hourly turnover in a month, just ahead of the final fixing that took place at 1000 GMT.
The currency was fixed at 3.9603, a figure widely expected to be low enough to keep the debt level below the 55 percent threshold.
The zloty had shrugged off Thursday's news of planned changes in the Polish pension system as the move was less radical than in Hungary and will lead to lower debt and deficits next year.
Polish Prime Minister Donald Tusk unveiled plans to cut employees' contributions to mandatory private pension funds to 2.3 percent of their monthly salaries from 7.3 percent to help shore up budget finances. [
]Yields on Polish 10-year bonds jumped 5 basis points on Thursday on the news but there was no significant activity on the market on Friday.
In 2010 the zloty has gained 3.8 percent against the euro, while the Czech crown <EURCZK=> has risen around 5 percent.

The crown hit its highest level since Dec 10 on Friday in very low liquidity after bouncing off a key resistance level earlier in the week.
"It's all a matter of two factors, very poor liquidity and, of course, the euro/dollar is at highs now," said Lubos Kolarik, a dealer at Komercni Banka.
The currency gained 0.1 percent on Friday, breaking through its 200-day moving average -- a positive technical signal.
Hungary's forint also firmed in thin turnover but it continued to underperform the region. It has lost 3 percent versus the euro in 2010.
The firmer euro also helped the forint rebound against the Swiss franc <CHFHUF=> though it remains near the record lows to the Swissie hit in September, fuelling fears that more Hungarian households may default on franc debt next year. Yields on Hungarian government paper dropped by some 2-3 basis points on Friday.
Liquidity on the country's foreign exchange and fixed income markets is likely to remain low in the first two weeks of 2011 and dealers said news from the euro zone debt crisis would set the trend for Hungarian assets early next year.
"International trends, and within that the euro debt crisis and the (movement of the) euro itself, will determine what happens here," one Budapest-based currency dealer said.
"The government is due to outline its reform plans in February... Until then the (domestic) market could be in a wait-and-see stance."
The Romanian leu <EURRON=> gained 0.1 percent in thin trade, also helped by the stronger euro. --------------------------MARKET SNAPSHOT-------------------- Currency Latest Previous Local Local
