NEW YORK, Dec 15 (Reuters) - U.S. and European stocks fell on Monday as New York state manufacturing data pointed to tumbling demand and more signs of economic weakness that weighed on the dollar and helped lift government debt prices on either side of the Atlantic.
Oil prices eased as deepening economic worries countered expectations that the Organization of Petroleum Exporting Countries would agree to its biggest supply cut ever when the cartel meets in Algeria this week to prop up slumping crude.
The euro rose more than 2 percent to a two-month high against the dollar on speculation the Federal Reserve will cut interest rates to a record low near zero on Tuesday, a move that would further erode the greenback's yield appeal.
The urgency for the Fed to take more bold steps intensified after fresh manufacturing data for December showed evidence of deflation. The prices paid index in the New York Fed's "Empire State" manufacturing report posted a record decline.
"We are still getting poor economic data," said Bernard McAlinden, market strategist at NCB Stockbrokers in Dublin.
"The New York manufacturing index was weaker again in December and some earning figures are coming out negative. There are worries the market has not yet priced in all of the concerns about the economies and earnings," he said.
The one-month Treasury bill rate <US1MT=RR> briefly traded below zero percent, suggesting investors were willing to suffer small losses as long as they believed most of their principal is shielded from the steep losses in many investor portfolios.
Buyers "are pretty much telling the market that they don't think we are near a bottom and the current recession will be with us for a while," said Kevin Giddis, head of fixed income sales, trading and research at Morgan Keegan in Memphis.
"It doesn't seem to matter how much the Treasury brings to market because investors are so worried about the stability of the financial system that they are willing to accept zero return on their investment," he said.
Renewed worries about a deep recession weighed on U.S. and European equities, with banks the big losers. A 6.2 percent slide in JPMorgan <JPM.N> led the Dow lower while BNP Paribas <BNPP.PA> led shares lower in Europe, off 10 percent.
Investors worried about potential heavy losses ahead of results from Goldman Sachs <GS.N> and Morgan Stanley <MS.N> after Merrill Lynch downgraded JPMorgan and forecast a fourth-quarter loss for the bank.
With the holiday shopping season in full swing, fears about weak consumer spending dragged on shares of Apple <AAPL.O>. Goldman Sachs cut its rating on the maker of the iPod and iPhone and its shares fell nearly 4 percent. For details see [

The dollar started to respond negatively to concerns about further weakness in the U.S. economy, analysts said, after the weak manufacturing data caused an exodus from risky positions and increased flight-to-quality buying in the currency.
Investors shunned the greenback amid fears a failure of one or more of the Big Three U.S. automakers could exacerbate a yearlong recession and drag down other companies.
"The uncertain outlook for the U.S. automakers continues to keep investors wary of over exposure to the dollar at this point," said Omer Esiner, senior market analyst at Ruesch International in Washington.
"We're seeing a naturally weaker dollar as we get into the year end, so bad news is only exacerbating the need for investors to just exit their long dollar positions," he said.
The dollar fell against a basket of major currencies, with the U.S. Dollar Index <.DXY> down 1.68 percent at 82.304. Against the yen, the dollar <JPY=> fell 0.53 percent at 90.62.
The euro <EUR=> rose 2.10 percent at $1.3653.
Oil briefly topped $50 a barrel before tumbling to almost $45 a barrel as dealers eyed stock market losses even as OPEC members agreed on the need to cut output, according to the group's president, Chakib Khelil, who spoke to reporters in Oran, Algeria.
Saudi Arabia, the world's biggest exporter, cut its supply by 8 percent and this had affected the market, he said.
