(Adds close of U.S. markets)
By Herbert Lash
NEW YORK, May 5 (Reuters) - U.S. stocks fell on Monday as resurgent oil prices set a record over $120 a barrel and doubts about Bank of America's plan to buy the largest U.S. mortgage lender renewed concerns about the nation's economic health.
The jump in crude oil on supply concerns from OPEC members Nigeria and Iran fanned fears about the outlook for consumer spending and overshadowed a report that showed the U.S. service sector in April defied expectations and posted its first monthly gain this year.
The dollar, meanwhile, fell against the euro and the yen as investors debated the strength of the U.S. economy amid the high oil prices.
While the slip in U.S. stocks was the main driver of U.S. Treasuries, bond bulls cut bets that the United States will suffer a steep recession and expectations the Federal Reserve will cut interest rates further due to the latest evidence of economic resilience.
Financial shares fell after a brokerage said Bank of America <BAC.N> is likely to renegotiate or even walk away from its deal to acquire ailing mortgage lender Countrywide Financial Corp <CFC.N>.
Countrywide shares tumbled 10.4 percent to $5.36 and pulled the broader market lower on fears a scotched deal would show the credit crisis is deepening and has not abated.
"If they were to walk away from this deal, what will that mean? Will Countrywide have to file for bankruptcy? Will all the Countrywide paper get dumped into the market? Nobody knows," said Stephen Massocca, co-chief executive at San Francisco-based investment bank Pacific Growth Equities.
"It may be that there are reasonable answers to all this, but if that were to happen, that won't be good for the market," he said.
The Dow Jones industrial average <
> was down 88.66 points, or 0.68 percent, at 12,969.54. The Standard & Poor's 500 Index <.SPX> was down 6.42 points, or 0.45 percent, at 1,407.48. The Nasdaq Composite Index < > was down 12.87 points, or 0.52 percent, at 2,464.12.News that Microsoft Corp <MSFT.O> had dropped its offer to buy Yahoo Inc <YHOO.O> for $47.5 billion added to investors' pessimism. Yahoo <YHOO.O> slumped 15 percent to $24.37 and Microsoft <MSFT.O> slipped 0.6 percent to $29.08.
Shares of Google <GOOG.O> rose 2.3 percent to $594.90 on expectations it could benefit from Microsoft's failed takeover bid. Yahoo was likely to push for an advertising partnership with the Web search company, sources familiar with the matter said.
European shares ended lower, breaking a three-day winning streak, as techs and telecoms weighed and offset the impact of the surprisingly strong U.S. service sector figures. With UK markets closed for a public holiday, trading was thin.
The pan-European FTSEurofirst 300 <
> index of top European stocks ended down 0.3 percent at 1,357.99 points.Tech stocks weighed in Europe after Microsoft's bid for Yahoo fell apart. Chip equipment maker ASML <ASML.AS> lost 2.3 percent, while in the telecoms sector, Alcatel-Lucent <ALUA.PA> lost 1.9 percent; Ericsson <ERICb.ST> shed 1.1 percent and Nokia <NOK1V.HE> lost 1.5 percent.
Stocks got a brief fillip from data that showed the U.S. service sector grew unexpectedly in April, snapping a three-month period of contraction, and adding to signs that the United States might skirt a recession.
The Institute for Supply Management's non-manufacturing index rose to 52.0 versus 49.6 in March. ISM's jobs gauge for the sector posted its biggest improvement in seven months but inflation pressures were at a five-month high.
"The report is consistent with the trend we have been seeing that the U.S. economy is not as disappointing as many initially thought," said Nick Bennenbroek, head of foreign exchange strategy at Wells Fargo in New York.
U.S. Treasury debt prices mostly rose as financial shares pulled stocks lower and boosted investor demand for lower-risk assets like government debt.
The benchmark 10-year U.S. Treasury note <US10YT=RR> rose 2/32 to yield 3.85 percent. The 2-year U.S. Treasury note <US2YT=RR> rose 2/32 to yield 2.42 percent. The 30-year U.S. Treasury bond <US30YT=RR> fell 4/32 to yield at 4.59 percent.
The dollar extended losses as uncertainty about the outlook for the economy kept investors wary of declaring a sustained dollar recovery.
The euro rose 0.4 percent to $1.5489 <EUR=>, shrugging off earlier data showing euro zone investor morale had unexpectedly weakened in May. Investors were far more concerned with the expected trajectory of European Central Bank interest rate policy.
With food and energy costs on the rise, ECB President Jean-Claude Trichet warned again on Monday of "significant" inflation risks, suggesting benchmark rates would likely stay fixed at 4 percent when the central bank meets on Thursday.

"People are piling back up on crude oil due to the weakness of the dollar and production issues in Nigeria," said Phil Flynn, analyst at Alaron Trading in Chicago.
In Nigeria, Royal Dutch Shell <RDSa.L> was forced to shut more of its production after militants on Saturday attacked a flowstation in the oil-rich Niger Delta.
U.S. gold futures ended nearly 2 percent higher in thin volume following sharp losses last week. Record high crude oil prices helped lift bullion back toward the $900 level.
The June contract <GCM8> in New York settled up $16.10, or 1.9 percent, at $874.10 an ounce. The London gold fix was not available because of the bank holiday.
In Asia, Japan was on holiday, but in Hong Kong stocks fell from the previous session's three-and-a-half-month high, closing down 0.22 percent.
