* Currencies add strong gains ahead of ECB, G20
* Czech, Polish debt auctions continue to help
* Global mood improves on U.S. and UK data

BUCHAREST, April 1 (Reuters) - Central European currencies extended gains on Thursday, led by the Polish zloty as the success of Wednesday's debt tenders continued to help and U.S. data sparked some hope for investors.
Global risk appetite was boosted by U.S. factory and home sales data released late on Wednesday, which spurred optimism that the U.S economy has bottomed out, while house prices in Britain posted their first rise since 2007.
In the region, stocks continued to climb, while well-bid Czech and Polish debt auctions on Wednesday prompted investors to turn more bullish after central European debt markets were under pressure for months.
Market talk on Wednesday that the ECB may intervene to help the currencies of EU's emerging markets also continues to give support, dealers said, although analysts said this move was unlikely to happen.
"Data in U.S. and UK, hopes for ECB helping the region and the debt auctions give strong support," one dealer said. "Bullish is the word for the markets today."
By 0736 GMT, the Polish zloty <EURPLN=> and the Hungarian forint <EURHUF=> were leading gains in the region, adding around 1.5 percent from Wednesday's domestic close. The Czech crown <EURCZK=> firmed about 0.6 percent and the Romanian leu edged up.
But currencies were slightly off morning highs, and investors were also eyeing an ECB meeting later in the day and the results of a Group of 20 meeting in London.
"Even though the overall results of the G20 summit are limited, effects for the EMEA currencies are likely to be positive," Commerzbank said in a morning note.
"It is likely that the summit will agree to an increase of IMF funds to the level required by the IMF of $250 billion."
While regional assets were rising, credit ratings agency Moody's issued ratings downgrades on two of Austria's biggest banks exposed to emerging Europe on Wednesday, following up on a warning that rattled emerging European markets in February.
Moreover, Czech Republic and Hungary have been hit by a fall of governments and Budapest suffered downgrades by S&P and Moody's this week, adding weakening pressure on regional assets.
"We'll see how long global hopes will offset the negative outlook in the region," one currency dealer in Bucharest said. ----------------------MARKET SNAPSHOT------------------------- Currency Latest Previous Local Local
