BUDAPEST, Sept 4 (Reuters) - Central European currencies gave up early gains on Thursday, hit by the dollar's surge against the euro, the region's reference currency, and the European Central Bank's comments on growth and inflation.
"The dollar's <EUR=> gains wiped out profits in the region," said David Sykora, a trader at CSOB bank in Prague.
"Sentiment was hurt by comments from (ECB President Jean-Claude) Trichet pointing to a euro zone economy slowing down."
The Czech crown <EURCZK=> eased 0.14 percent against the euro to 24.86 by 1459 GMT.
The forint <EURHUF=>, which has been the region's most volatile unit for weeks, again led the falls as late dollar gains against the euro pushed the exchange rate through key resistance levels at around 240 forints against the euro.
It hit 11-week lows at 241.55 versus the euro and traded at 241.35 at 1459 GMT, 1.16 percent weaker than Wednesday. Dealers said its next target was 242.
"Sizeable stop-loss deals were triggered at several levels near 240... the dollar is firming and that weakens the whole region," one dealer in Budapest said.
Dealers said uncertainty over parliamentary support for the minority government's budget plans maintained risks to asset prices in Hungary and a fall by Poland's zloty <EURPLN=> earlier in the day also contributed to the forint's late slump.
The zloty shed 0.92 percent against the euro by late trade and was bid at 3.397. It was undermined after the ECB on Thursday said euro zone inflation would not ease back to the ECB target until 2010.
"The zloty loses as interest rate disparity expectations dwindle. The ECB, which left interest rates unchanged, shows it is determined to fight inflation," said Jakub Borowski, chief economist at Invest Bank in Warsaw.
"I would expect the zloty to stabilise at 3.40 against the euro, as the (Polish Monetary Policy) council raises interest rates one more time this year," he added. The Polish central bank's key rate is at 6.0 percent.
The region's currencies, which hit record highs in the summer, have retreated in the past weeks as a slowdown in growth overshadowed earlier rate hike expectations and because of concern about the possible impact of the Russia-Georgia conflict.
Hungary will on Friday publish detailed second-quarter economic growth data and July industrial output figures. ----------------------MARKET SNAPSHOT------------------------- Currency Latest Previous Local Local
