NEW YORK, Aug 25 (Reuters) - The U.S. dollar was lower against the yen and steady against the euro on Monday ahead of a report on U.S. existing home sales for July which could add to recent signs of stability in the U.S. housing market.
Economists polled by Reuters are expecting existing home sales to rise to a 4.90 million rate in July with the data set for release at 10:00 a.m. (1400 GMT). A recovery, or at least stabilization, in the U.S. housing market is seen as critical to ending some of the concern on the U.S. economy.
The British pound hit two-year lows against the dollar on Monday, with stalled UK growth seen as another example of growing economic malaise outside the United States. The pound later recovered but its weakness helped the revival of the dollar against some currencies including the euro. Trade was thin in Europe due to a UK public holiday.
"We have thin markets with London out so we could see some silly moves," said Ron Simpson, director of FX currency research at Action Economics in Tampa, Florida.
Sterling bounced up 0.1 percent to $1.8542 <GBP=> as the New York session opened, having fallen as low as $1.8407 earlier -- its lowest since July 2006, according to Reuters data. The pound is down 6.6 percent against the dollar in 2008, the largest drop of any major currency other than the New Zealand dollar.
Data on Friday showed the UK economy ground to a halt in the second quarter of the year, its worst quarterly performance since 1992, highlighting the risk of a British recession and raising the chance of a UK interest rate cut later this year.
"The growth number confirmed our worst expectations. We've seen that the fall in house prices in the UK seem to have no end. We cannot detect this bottom in house prices that everyone seems to be looking for," said John Hydeskov, senior FX analyst at Danske bank in Copenhagen.
The dollar index, measuring the U.S. unit's value versus a basket of six major currencies, was 0.2 percent lower at 76.660 <.DXY>.
The euro was little changed at $1.4800 <EUR=> and down 0.4 percent at 162.15 yen <EURJPY=>, while the dollar eased 0.4 percent at 109.57 yen <JPY=>.
The euro remained little changed after news the IMF is cutting its 2008 growth estimate for the euro zone to 1.4 percent from 1.7 percent, according to a source. The IMF forecast for 2009 was revised to 0.9 percent versus 1.2 percent, the source said. For more details, click [

In addition to stalling economies in the euro area and Japan, the UK growth scenario helped fuelled a view that interest rates outside the United States may be headed lower, supporting the case for an extension of the dollar's gains.
Bank of Japan Governor Masaaki Shirakawa said on Monday the nation's economic growth will likely remain sluggish due to high energy costs and slowing export growth [
]."The general sentiment towards lower rates and towards the U.S. economy managing to get out of the global crisis earlier than the other economic areas will support the dollar over the next couple of months," said Antje Praefcke, currency strategist at CBCM in Frankfurt.
Wile the global economic slowdown and the outlook for monetary easing outside the United States were supportive, some market participants remained sceptical about the dollar's sharp gains due to persistent worries about the U.S. financial system.
In addition to problems at U.S. mortgage finance companies Fannie Mae <FNM.N> and Freddie Mac <FRE.N>, and speculation over investment bank Lehman Brothers <LEH.N>, traders will also be scrutinizing the slew of U.S. housing data this week. Data on new home sales for July and two surveys of nationwide house prices are expected to be released on Tuesday.
