* Zloty set for strong April gains, other FX near highs
* Romania keeps 2015 euro target, leu stays near 13-mth high
* Turnover thin as London markets closed

BUDAPEST/PRAGUE, April 29 (Reuters) - The Polish zloty rose on Friday on reports a state-owned bank was selling euros in the market, and was headed for its best monthly gain since July as emerging European currencies mostly firmed.
The weakening dollar has boosted investors' appetite for higher-yielding assets, and central Europe's currencies have traded near new highs since the U.S. Federal Reserve maintained its ultra-loose policy this week.
The zloty <EURPLN=> rose 0.2 percent to 3.932 against the euro by 1348 GMT and was set to finish April with a 2.5 percent gain.
The Polish currency has been helped by Finance Ministry plans to regularly sell some of the funds it receives from the European Union on the spot market under a plan to support the zloty. 
Dealers said Poland's state-owned bank BGK, which can sell euros on behalf of the finance ministry but is also able to do its own transactions, was seen on the spot market on Friday. 
BGK declined to comment and it was not clear whether the bank was acting on its own account or for the finance ministry.
"Any presence of BGK in the coming weeks will raise speculation as to whether it's the finance ministry or just BGK as a regular market player," said one Warsaw-based dealer.
The Hungarian forint <EURHUF=> and the Romanian leu <EURRON=> were up 0.1 percent at 264.08 and 4.074 to the euro, respectively. The Czech crown <EURCZK=> eased a quarter of a percent.
Activity was slightly muted with London markets closed for the royal wedding. Hungarian government bonds were a shade firmer from Thursday but turnover was very low.
The region's stock markets fell by up to 1 percent.
CARRY TRADE ATTRACTIVE
Romania's centrist coalition government maintained its 2015 euro adoption goal in its euro convergence programme approved on Friday, knocking down reports this week that it would drop the date. 
Romania, a European Union member since 2007, had the fastest growth rate in the bloc until a real estate and credit bubble burst in 2008 forcing it to seek IMF-led aid as it fell into recession. Analysts have suggested the 2015 target was overly optimistic.
An International Monetary Fund team started a review of Romania's new two-year aid deal on Wednesday that will continue through May 9. It is widely expected to note Romania's progress in meeting fiscal deficit targets. 
The leu was trading at around a 13-month high and the forint stayed near its highest in a year.
The forint has been emerging Europe's best performing currency this year, followed by the leu and the crown. The zloty's April gains helped erase losses seen since the start of 2011.
The crown, a funding currency in the region due to low Czech interest rates, stayed near a 2-1/2 month high it hit this week. Markets were looking to a central bank policy meeting next week, with rates seen staying where they have been since May 2010.
In Hungary, investors are attracted by high interest rates -- at 6 percent <NBHI> -- and continued optimism on Budapest's fiscal plans, which they hope will keep the budget deficit below 3 percent of GDP in coming years after an expected surplus this year due to big one-off revenues. --------------------------MARKET SNAPSHOT-------------------- Currency Latest Previous Local Local
