NEW YORK, March 22 (Reuters) - Markets took a breather on Tuesday after days of volatility, as uncertainty over the fighting in Libya kept both stocks and U.S. government debt in a narrow range
Oil prices edged higher, with Brent trading above $115 after an earlier drop as unrest in Yemen raised concerns about a further threat to supply from the Gulf region.
The euro retreated from a 4-1/2-month high against the dollar but expectations that the European Central Bank will hike interest rates next month could limit any downside for the currency.
Economic data has taken a back seat to world events as investors fretted over the extent of nuclear reactor damage in quake-stricken Japan, while political instability in the Middle East and North Africa has kept oil prices volatile.
The MSCI global stocks index <.MIWD00000PUS> was up 0.2 percent, boosted by an overnight rise in Japanese stocks, but European and U.S. equity benchmarks fell slightly.
Tokyo's benchmark Nikkei average <.N225> added 4.4 percent
as traders returned from a national holiday. Progress in
attaching power cables at the stricken nuclear plan encouraged
traders to buy domestic shares after last week's losses of more
than 10 percent. Later in the day, U.S. dollar-denominated

"There is a lot of volatility and a lot of uncertainties surrounding Japan and Libya," said Tim Ghriskey, chief investment officer at Solaris Asset Management in Bedford Hills, New York.
"Neither one of the situations looks quite ready to settle down yet and that could drag out for some time and weigh on the market."
The Dow Jones industrial average <.DJI> dropped 11.43
points, or 0.09 percent, to 12,025.10. The Standard & Poor's
500 <.SPX> fell 2.87 points, or 0.22 percent, to 1,295.51. The
Nasdaq Composite <.IXIC> lost 6.89 points, or 0.26 percent, to
2,685.20.
