NEW YORK, Feb 22 (Reuters) - U.S. stocks fell on Friday as a broker downgrade of the two biggest U.S. home-funding companies signaled the likelihood of further deterioration in credit markets, intensifying fears of a recession in the world's largest economy.
Safe-haven U.S. government debt rose on the stock market's decline, and spurred by a fresh round of poor U.S. economic data, the dollar fell to a three-week low against the euro. Data showing growth in euro zone services also underpinned the strength of the single European currency.
European shares fell as downbeat results from Germany's RWE <RWEG.DE> hit utilities and as fears of a U.S. recession hurt banks. In Japan, shares also fell on fears of a U.S. recession and shares of exporters fell as the yen strengthened.
Merrill Lynch recommended investors sell Fannie Mae <FNM.N> and Freddie Mac <FRE.N>, the largest U.S. home-funding companies, as they face more pain due to further deterioration in financial markets and weakening credit conditions.
The downgrades were the latest dismal new for the U.S. financial sector, which is suffering from defaults in the subprime mortgage market and tightening credit markets.
"The big issue is, 'Where is the subprime problem going to pop up again?'" said Lincoln Anderson, chief investment officer at LPL Financial Services in Boston.
Shares of Fannie Mae, the largest home financing company, fell 4.7 percent and No. 2 Freddie Mac dropped 8.4 percent. The S&P 500 financial index <.GSPF> was down 1.2 percent.
The release of revised data for U.S. wholesale price inflation appeared less severe, but the calculations do not affect unadjusted data, which still shows its Producer Price Index on a sharp ascending trend.
Compared with December 2006, overall producer prices were up 6.3 percent last year for the largest increase since a 7.1 percent advance in 1981, the U.S. Labor Department said.
The department said that wholesale price inflation was more muted at the end of 2007 than previously thought.
The department said PPI, a gauge of price changes at the farm gate and factory door, dropped by 0.3 percent in December instead of 0.1 percent that it reported on Jan. 15.
November producer prices that had originally been reported rising sharply by 3.2 percent instead were up by a somewhat more modest 2.6 percent, the department said.
EUROPEAN SHARES FALL
In Europe, shares of RWE, Germany's second largest utility, fell nearly 6.5 percent after the company reported disappointing earnings and said earnings could be unchanged this year. The news hit shares of rival utility E.ON <EONG.DE> and others.
The FTSEurofirst 300 index <
> of top European shares ended down 0.8 percent at 1,320.04 points, and is now off almost 13 percent since the start of the year.The broader European market gained for the second week in a row, but sentiment has been plagued by worries about the U.S. economy and corporate profitability.
"The markets are being pulled between information on the here and now, which is quite discouraging, and hopes that more aggressive action to try to reflate the U.S. economy in say nine months time, things will look a lot better," said Andrew Bell, a European strategist at Rensburg Sheppards.
Financials, which have borne the brunt of the fallout from the U.S. subprime crisis, were mixed.
Lloyds TSB <LLOY.L> raised the write-down on its exposure to risky assets to 280 million pounds but a 6 percent rise in underlying 2007 profit and an increase in its dividend boosted the stock 4.8 percent.
France's BNP Paribas <BNPP.PA> fell 0.8 percent and Germany's Postbank <DPBGn.DE> gained 1.7 percent. UBS <UBSN.VX> shares lost 1.9 percent.
Oil fell below $98 a barrel, handing back early gains in choppy trading, as falling U.S. stock markets put the focus back on economic woes in the world's largest oil consumer.
U.S. crude oil futures for April delivery <CLc1> rose 79 cents to $99.02 a barrel, as prices seesawed amid concerns about about economy and supply worries related to an incursion into Iraq by Turkish troops. A rise in heating oil futures on colder weather supported prices. London Brent crude <LCOc1> gained 6 cents to $96.30 a barrel.
The dollar declined to three-week lows against the euro as the euro zone's surprising growth in the service sector showed a clear contrast with the flagging U.S. economy. The data dampened expectations the European Central Bank will cut interest rates in the near term, in contrast to expectations of further rate cuts by the U.S. Federal Reserve.
Long-dated U.S. Treasuries edged higher following a strong rally the previous session that was triggered by a survey of mid-Atlantic business conditions showing activity at its lowest level since the 2001 recession.
Treasuries rallied on Thursday after the Philadelphia Federal Reserve's business conditions index contracted for the third straight month, pointing to a manufacturing recession.
Traders took profits on yield-curve steepening trades that had pushed the gap between two- and 10-year yields to 192 basis points, the widest gap in almost four years, traders said.
The fundamental argument for yield curve steepening is that the Fed continues to cut benchmark short-term interest rates to limit an economic slowdown while inflation readings remain firm enough to require a premium for long-dated bonds. (Editing by Leslie Adler)
