The United States and its major industrial partners are unlikely to issue a statement soon -- as reported in international financial markets -- reaffirming the Louvre accord to stabilize the dollar, sources here and in Europe said yesterday.

Moreover, disagreements between the United States and the other nations make the prospect for a new meeting of the Group of Seven (G-7) uncertain.

Reports that the G-7 -- the United States, Japan, West Germany, England, France, Italy and Canada -- would issue a statement soon reaffirming their intention to stabilize the dollar firmed up the sliding American currency yesterday after it again hit postwar lows in world money markets.

In late New York trading, the dollar was at 1.6344 West German marks, up from 1.6175 Thursday, and at 127.06 yen, up from 125.90.

The dollar also benefited from testimony by Federal Reserve Board Chairman Alan Greenspan that America's record October trade deficit might prove to be "an aberration" when the next monthly figures are published.

"No statement or meeting can reaffirm the Louvre accord," said one of the key European players. "It would be foolish, because there is no agreement that could back it up."

The Louvre accord last February pledged that the nations involved would stabilize monetary exchange rates "around {then} current levels," which they said reflected an underlying equilibrium. They also promised to take economic policy actions that would make continued exchange rate stability possible.

But the accord disintegrated when most nations -- especially the United States and West Germany -- were unable to carry out their part of the bargain without taking steps that were politically unacceptable. Only Japan followed through with a meaningful fiscal push, despite a rapidly appreciating currency.

Officials of the G-7 nations have been discussing for 10 days a statement that could be issued after Congress adopts the budget reduction package negotiated between the White House and congressional leaders after the stock market collapse.

The intention of the statement, a participant in the talks said, is to demonstrate -- especially to financial markets -- that the nations are ready to work together again.

"After all of the public recriminations between Baker and the Germans that we had last October, we need some kind of statement to stress cooperation, to show that {the leaders} are talking again," he said. Observers had said such a statement could be issued as early as this weekend.

Word of these discussions leaked in Bonn and Tokyo yesterday. Bonn government sources were quoted as saying finance officials "have concluded very intensive consultations" about renewing economic and monetary policy cooperation.

But sources in other capitals, including Washington, downplayed the likely content of the proposed statement and were not optimistic about an early G-7 meeting.

"The United States seems less interested in a meeting than may have been the case before," said one European central banker. "Secretary {James A.} Baker sees more disadvantages to the U.S. than advantages at this point."

He said the United States has made plain that it has no intention of raising interest rates -- the one sure route to meeting the European-Japanese demand for stopping the dollar's slide.

"They {the Americans} tell us that if we want to stabilize the dollar, we can continue to intervene. Then we ask them to issue 'Reagan bonds,' and Baker says 'no,' " the European central banker said.

"Reagan bonds" would be American securities denominated in foreign currencies, a method that would transfer the exchange rate risk of a declining dollar from foreign investors to the American government. Baker has ruled out that step for now, concluding that it would remove the pressure on West Germany and Japan to expand their own economies.

With the major nations still far apart on how to achieve stability in exchange markets, some of them see a new G-7 meeting as a risky exercise that would be viewed as useless by financial markets.

One additional factor that weakens the ability of the Europeans and the Japanese to pressure the United States, according to Dietrich von Kyaw, a West German economic aide in Washington, is the recent slide in oil prices. That helps offset the inflationary pressure that may come from a declining dollar and enables the United States to accept a further dollar drop.
