NEW YORK, Jan 26 (Reuters) - U.S. stocks dropped in a late-day swoon on Tuesday ahead of major political and regulatory developments, while the dollar and yen climbed against most of their major counterparts as China implemented a clampdown on bank lending.
U.S. Treasury debt prices rose as stocks, having been up for most of the session, drooped into the close. Bonds also rose on China and President Barack Obama's call for a freeze on federal spending on many domestic programs.
China's central bank ordered banks that need to raise their reserve ratios to implement the change on Tuesday, banking sources said ID:nSGE60P039. In recent weeks, China has moved to cool bank lending to curb inflation and forestall asset bubbles. "Since China has started its banking proposals ... this has generally been seen as a concern," said Justin Urquhart Stewart, director at Seven Investment Management.
The dollar and yen climbed against higher-yielding currencies on speculation China, the world's growth engine, will take further steps to cool its economy, discouraging demand for higher-yielding assets.
For their part, U.S. equity gains fizzled late on Tuesday as investors turned cautious before the Federal Reserve's policy announcement and President Barack Obama's State of the Union address on Wednesday. For details, see ID:nN25224485
The Fed's Open Market Committee began a two-day meeting on Tuesday against the backdrop of a Senate debate over Chairman Ben Bernanke's reconfirmation. The meeting is expected to yield few policy shifts, with a Fed statement on the economy and interest rates expected on Wednesday.
With news flowing on many fronts, world stocks as measured by the MSCI world equity index fell 0.7 percent with their emerging market component -- a sector particularly sensitive to China -- down 2 percent. Emerging stocks, last year's star performer with a nearly 75 percent gain, have lost more than five percent so far this year.
Adding to China worries, Standard & Poor's cut its outlook on Japan. The rating agency threatened to cut Japan's credit rating unless it produced a credible plan to rein in soaring debt and lift growth in an economy plagued by persistent deflation.
Japan's Nikkei closed down 1.8 percent. That was before S&P cut its outlook.
TRAVELERS, APPLE HELP STOCKS
U.S. equities slipped on investor nervousness over political and regulatory developments. Reuters reported that former Federal Reserve Chairman Paul Volcker is tentatively scheduled to testify next week on the latest White House bank regulation proposals to the U.S. Senate Banking Committee.
Investors and analysts said that helped to weigh on stocks.
The Dow Jones industrial average was down 2.57 points, or 0.03 percent, at 10,194.29, while the Standard & Poor's 500 Index was down 4.61 points, or 0.42 percent, at 1,092.17. The Nasdaq Composite Index was down 7.07 points, or 0.32 percent, at 2,203.73.
Equities were up for most of the session as Travelers led gains on the Dow. The property-casualty insurer posted a profit that beat Wall Street's estimate. The stock advanced 2.74 percent to $50.23.
IPhone maker Apple Inc gained 1.41 percent to $205.94, a day after reporting results. Apple was the top positive on the Nasdaq, followed by Microsoft Corp, which is scheduled to report later this week.
That said, U.S. Treasury debt prices gained on stocks' overall turnaround of fortunes.
The benchmark 10-year U.S. Treasury note was up 4/32, with the yield at 3.613 percent, while the 2-year U.S. Treasury note was up /32, with the yield at 0.8074 percent. The 30-year U.S. Treasury bond was up 3/32, with the yield at 4.545 percent.
In currencies, the dollar was up against a basket of major trading-partner currencies, with the U.S. Dollar Index .DXY> up 0.38 percent at 78.484 from a previous session close of 78.190.
The euro was down 0.53 percent at $1.4075 from a previous session close of $1.4150. Against the Japanese yen, the dollar was down 0.68 percent at 89.62 from a previous session close of 90.230.
In energy and commodities prices, U.S. light sweet crude oil fell 65 cents, or 0.86 percent, to $74.61 per barrel, and spot gold prices rose 55 cents, or 0.05 percent, to $1098.40. The Reuters/Jefferies CRB Index was down 2.86 points, or 1.03 percent, at 273.88.
