NEW YORK (AFP) - The dollar slid against the embattled euro late Friday as investors took profits and the German parliament approved Berlins share of a trillion-dollar rescue package for debt-stricken eurozone countries. The euro fetched 1.2563 dollars in New York at 2100 GMT, from 1.2482 dollars late Thursday, as the single European unit got some respite after plumbing four-year-lows earlier in the week on concerns over the European debt crisis. The dollar gained ground against the Japanese currency, at 89.93 yen from 89.62 yen late Thursday. Bank of New York Mellon analyst Samarjit Shankar said profit-taking on very extended short positioning and passage of a bill to unblock up to about 150 billion euros (187 billion dollars) of the around 750 billion euros in loan guarantees proved supportive for the euro. Whether this optimism can be sustained remains to be seen as market participants remain deeply concerned about the ability of various Eurozone governments to implement draconian austerity measures amid social unrest and the negative impact this is likely to have on growth in the region, he said. Kathy Lien, director of currency research at Global Forex Trading, said long term concerns about European growth remained and that is why the recovery in the euro against the dollar could be limited. She cited eurozone economic reports Friday providing first evidence that the turmoil in the markets was starting to take a toll on German businesses. German business confidence stagnated in May, the closely watched Ifo index showed Friday, as company heads tried to measure the potential effects of the eurozone debt crisis on their future. As the austerity plans are implemented, the impact on growth will become even more significant. Yes, the weak euro is stimulative, but it may not be enough to offset weaker domestic demand, Lien said. She pointed out that the lack of significant eurozone economic data next week meant that US fundamentals could become a driving force for the greenback once again. This is particularly possible now that the euro-US dollar has stabilized, reducing speculation that the currency would not find support until parity. In late New York trading, the British pound rose to 1.4470 dollars from 1.4353 dollars late Thursday while the greenback fell to 1.1506 Swiss francs from 1.1513.
