NEW YORK, Jan 7 (Reuters) - U.S. stock prices gyrated on Monday as investors concerned about a possible U.S. recession saw a drop in oil and gold prices easing some of those fears.
Following a more than 4.0 percent fall in U.S. stocks last week, markets globally were back up to full staff after the New Year holidays, with many investors reviewing the damage before making new bets for 2008.
Adding to some of the volatility was a brief incident involving U.S. and Iranian naval ships over the weekend in the Strait of Hormuz, a major oil shipping route in the Gulf.
After an initial rise, crude oil prices fell $2.56 a barrel to $95.35 <CLc1> on unseasonably warm U.S. weather and looming recession concerns. Oil hit a lifetime high last week above $100 a barrel.
Stock prices in Europe ended unchanged in a choppy session, while the U.S. dollar gained value as traders trimmed bets against the greenback on speculation that U.S. inflation may prevent aggressive cuts in interest rates.
"Overall, we still have concerns about inflation and inflation expectations," said Ron Simpson, director of currency research at Action Economics in Tampa, Florida.
U.S. Treasury Secretary Henry Paulson said on Monday the Bush Administration was considering how to give the economy a boost as it weathers a housing market decline.
Weak December U.S. jobs data on Friday raised concerns the U.S. economy may be headed for recession.
"With data on Friday showing unemployment ticking up, that's probably going to keep investors a little spooked," said Owen Fitzpatrick, head of U.S. Equity Group at Deutsche Bank Private Wealth Management in New York.

"Everyone is watching equities with one eye," said Richard Schlanger, portfolio manager at Pioneer Investments USA in Boston. "The market is pricing in for a significant economic slowdown."
Yields on the two-year Schatz <EU2YT=RR>, often viewed as the most sensitive to investor thinking on the likely course of monetary policy in Europe, were at 3.788 percent, compared with 3.749 percent late on Friday, in their first rise for a week.
