* Dollar advances against most majors on safe haven bid
* Risk aversion high despite Obama's optimistic tone
* Lower U.S. housing sales help dollar's safe-haven appeal (Recasts, updates prices, adds comment)

NEW YORK, Feb 25 (Reuters) - The dollar rose on Wednesday as investors remained averse to risk even as key U.S. officials, including President Barack Obama, sounded a more optimistic tone.
Late on Tuesday, in his first speech to Congress, Obama tried to reassure Americans the country would emerge stronger from the financial crisis, but analysts said he shed little light on how his administration would stabilize the economy. For more see [
].The dollar extended gains against the euro on Wednesday, after data showed the pace of sales of existing U.S. homes fell 5.3 percent in January. [
]. The housing report also helped send U.S. stocks lower. [ ]."The negative housing data -- the lack of any bottom in the plummeting housing market -- along with sharply lower stocks this morning have rekindled the demand for safe-haven dollar assets," said Omer Esiner, senior market analyst at Ruesch International in Washington. "So we're seeing the dollar rally to highs of the day against the euro, sterling, Canadian dollar and a number of its major rivals."
Midway through the New York session, the euro was down 0.7 percent against the dollar at $1.2746 <EUR=>, after earlier touching a session low of $1.2691. Sterling was down 1.5 percent at $1.4260 <GBP=>.
Obama's address to Congress followed testimony by Federal Reserve Chairman Ben Bernanke on Tuesday to a congressional committee that the significant value built up in the country's banks would be lost if the government owned them, easing investor fears that shareholders would be wiped out if the banks were nationalized.
Bernanke's prepared testimony to the House Financial Services Committee on Wednesday was identical to the previous day. [
].The dollar has been in demand as one of the last safe-haven currencies at a time of global economic uncertainty and risk aversion even as the U.S. suffers its own economic problems. Any optimism that the global economy could be recovering, however, should prompt investors to sell the dollar and buy riskier assets and currencies.
"A more optimistic tone from U.S. President Obama as well as Bernanke has not triggered a sharp rally in the euro or the pound," said Marc Chandler, global head of currency strategy at Brown Brothers Harriman in New York, in a note to clients. "The euro continues to be weighed down by problems in the euro zone."
Data on Wednesday showed Germany's economy contracted by a record 2.1 percent in the fourth quarter, dragged down by foreign trade. [

].YEN GAINS/FALLS
The yen, which had been one of the few other bright spots in foreign exchange markets on Wednesday, reversed direction and fell against the dollar as the New York session progressed. The dollar was last up 0.5 percent against the yen at 97.30 yen <JPY=>.
"There are a number of themes running through the market and it just depends on which is being focused on," said John McCarthy, director of foreign exchange at ING Capital Markets in New York. "You look at the data out of Japan and they have some serious problems."
Japan's exports nearly halved in January from a year earlier, with record slides in shipments to the United States, Europe and the rest of Asia pointing to a deepening recession across much of the world. [
