NEW YORK, May 19 (Reuters) - The U.S. dollar fell against major currencies on Tuesday as growing optimism that the global recession is moderating dented the greenback's safe-haven allure.
Data showing improving business sentiment in Germany and news that several major U.S. banks are asking to repay emergency funds they received from the government helped lift investor appetite for risk.
The dollar's losses were limited, though, by a report showing U.S. housing starts declined sharply to a record low last month.
"I think the key driver right now for the FX market is the outlook for global growth," said Camilla Sutton, senior currency strategist at Scotia Capital in Toronto.
"What we've seen in the last 24 hours are some indications that have given reason for the market to expect a little bit better global growth outlook than they had at the end of last week."
The greenback tends to fall when risk appetite rises as investors move money out of safe-haven dollar-denominated assets into riskier investments. Hopes that the global economy has turned a corner have stung the dollar in recent sessions.
In afternoon trading in New York, the ICE Futures' dollar index, a measure of the dollar's value against six major currencies, fell 0.5 percent to 82.138 <.DXY>.
The dollar index has lost more than 5 percent since it hit a roughly one-month high in April.
The euro traded at $1.3621 <EUR=>, up 0.5 percent on the day, although it was off the day's highs at $1.3655.
German data showed investors and analysts grew much more optimistic in May that economic conditions will be better late this year, with the monthly ZEW poll on economic sentiment hitting its highest since June 2006. For more, see [
].Technical analysts now expect the euro to test last week's high around $1.3721; a breach could pave the way for a move toward $1.40.
The euro rose 0.4 percent against the yen to 130.89 <EURJPY=>, while the dollar was off 0.2 percent at 96.10 yen <JPY=>.
NOT A "STRAIGHT-LINE"
Analysts said the data showing U.S. housing starts and permits unexpectedly fell to record lows in April doused the view that the housing market was stabilizing, denting optimism in the market. For more, see [

"We're not going to have a straight-line recovery," said Brian Kim, currency strategist at UBS in Stamford, Connecticut. "We may be hitting a bottom, but we still need time for reality to catch up with expectations."
Sterling <GBP=D4> jumped against the dollar, rallying above $1.55 to its highest level of the year. It last traded at $1.5483, up 0.9 percent on the day.
The pound had gained after a report earlier that Britain has held talks with investors to gauge interest in buying stakes in partly nationalized lenders. [
