* Oil falls on Chavez's Libya mediation proposal
* World stocks rise as oil dips
* Jobless claims boost US stocks
* ECB buoys euro with inflation comments (Updates prices, adds quotes, details)

NEW YORK, March 3 (Reuters) - U.S. stocks charged higher on Thursday, driven by better-than-expected U.S. labor market data and a pullback in oil prices, while the ECB president's warning about inflation triggered a rally in the euro.
Data showing new U.S. claims for unemployment benefits fell last week to their lowest level in more than 2-1/2 years was the latest optimistic reading to bolster hopes for an upside surprise in Friday's key payrolls report.
While European Central Bank President Jean-Claude Trichet's comments on inflationary risks were widely expected, he surprised investors by saying the bank may raise interest rates as soon as next month.
World stocks as measured by the MSCI Index <.MIWD00000PUS> rose 0.9 percent. On Wall Street, the Dow Jones industrial average <
> was up 179.10 points, or 1.5 percent.The progressively stronger data "has got hopes up that we are going to see better-looking non-farm payrolls numbers" in the Labor Department data, said Scott Marcouiller, chief technical market strategist at Wells Fargo Advisors in St. Louis.
On Wednesday, ADP data showed U.S. private-sector employers added more jobs than expected last month. The Labor Department's closely watched monthly payrolls report for February is due on Friday.
OIL AND GOLD SLIPS
Oil prices declined after Venezuela President Hugo Chavez made a proposal to try to broker a peace deal in Libya.
Some oil analysts suggested the Chavez proposal was a convenient excuse for traders to adjust their positions.
"If it's coming out of Chavez, it might not have a great degree of substance," said Tim Riddell, head of technical analysis at ANZ in Singapore.
"The fact that the markets have been so volatile, and without having concrete evidence of any material shift in the unrest in the Arab world, suggests to me that we are at best consolidating."
Brent crude oil <LCOc1> was down $1.86 at $114.49 a barrel. On Wednesday, crude approached 2-1/2-year highs as violence escalated in oil producer Libya.
Investors worry that if it is not soon halted, political instability could spread to major oil producer Saudi Arabia, a central U.S. ally in the region, and other oil suppliers.
Rising prices for oil and other commodities are pushing up prices for goods around the world, causing the heightened concern about inflation risks.
The latest batch of purchasing managers' indexes (PMI) in Europe and elsewhere again pointed to fast-building inflationary pressures, with Europe's private sector surging at its fastest pace in almost five years in February. For details, see [

The euro pierced resistance around $1.3958, its 200-week moving average, to hit as high as $1.3976 <EUR=EBS>, its strongest since Nov. 8, and on track to test the psychologically important $1.40 level.
Gold prices fell on Trichet's comment. Spot gold <XAU=>, which hit a record high this week, dropped as low as $1,417.22 an ounce.
Trichet said the ECB will exercise "strong vigilance" over rising inflation. For Trichet's comments see [
