* Geithner comment on SDR causes euro/dollar volatility
* Geithner says US dollar to remain top reserve currency
* Volcker says China proposal on SDRs not practical (Adds comment, updates prices)

NEW YORK, March 25 (Reuters) - The U.S. dollar fell against major currencies on Wednesday after U.S. Treasury Secretary Timothy Geithner said he was open to expanding the use of the International Monetary Fund's special drawing rights.
Investors initially interpreted his remarks as an endorsement of China's proposal on Monday to eventually replace the dollar as the world's reserve currency by the IMF's SDRs.
Geithner's comments sent the dollar falling to the bottom of its range of the last five day against the euro, although it did recoup some of its losses after the Treasury's top official said the greenback would keep its status as the top reserve currency for a long time. For details, see [
]."The market was caught off-guard by Geithner's statements and investors sold the dollar. I don't know why he said it...maybe he's trying to placate the Chinese," said Joe Francomano, vice president of foreign exchange trading at Erste Bank in New York.
"But his comments are not be taken lightly as the U.S. approaches debt of nearly $2 trillion. And when you say it as flippantly as he did, then that's very irresponsible."
In late afternoon trading, the euro was up 1.0 percent against the dollar at $1.3596 <EUR=> after rising as high as $1.3649 in the wake of Geithner's remarks, according to Reuters data.
China's central bank governor said earlier this week that the world should consider the SDR, a basket of dollars, euros, sterling and yen, as a super-sovereign reserve currency. [
].Geithner, responding to a question at a Council of Foreign Relations event in New York, said he had not read the Chinese proposal but added, "as I understand it, it's a proposal designed to increase the use of the IMF's Special Drawing Rights. I am actually quite open to that suggestion.
And he added, "But you should think of it as rather evolutionary, building on the current architecture, than -- rather than -- rather than moving us to global monetary union."
INITIAL DOLLAR SELL-OFF UNJUSTIFIED
Paul Volcker, a senior adviser to the Obama administration, thinks China's proposal was not practical. When the Chinese questioned the dollar's role as the world's reserve currency, "they ignore the fact that they didn't have to buy those dollars in the first place so they contributed to the problem."
Some analysts said the initial sell-off in the dollar after Geithner's statement was not justified.
Marc Chandler, global head of currency strategy at Brown Brothers Harriman in a note to clients said President Barack Obama's recent comments about the dollar being fundamentally strong, and there being no need for another reserve currency, was a better underlying guide to the U.S. administration's position.
IMF Managing Director Dominique Strauss-Kahn also gave his full support for the U.S. dollar on Wednesday, saying the greenback's days as the world's top reserve currency are not over, adding the Chinese believe so as well. [
].Against the yen, the dollar fell 0.3 percent to 97.42 yen<JPY=>, trading between a peak of 98.34 and a low of 96.93.
The Norwegian crown was also in focus on Wednesday, falling against the euro and dollar after the Norges Bank cut interest rates by half a percentage point to 2 percent.
The dollar was 1.8 percent higher at 6.5135 crowns <NOK=>, while the euro climbed 2.9 percent to 8.8530 crowns <EURNOK=>.
The pound, meanwhile, fell against the dollar <GBP=> to $1.4554, down 0.8 percent on the day. It initially rose on Geithner's remarks.
Sterling was pressured earlier after UK data showed retail sales fell more sharply than expected in March and after a UK gilt auction failed for the first time since 2002, suggesting reduced demand for sterling assets. [
