NEW YORK, May 16 (Reuters) -The Dow Jones industrial average crossed the 40,000 level on Thursday for the first time and a world stock index scored a third straight record intraday high on hopes ofU.S. interest rate cuts and strong earnings before stocks turned mostly flat in afternoon trading.

Data on Wednesday showed cooling consumer price inflation, although that was offset on Thursday by news that U.S. jobless claims fell in the latest week and by figures showing U.S. import prices increased 0.9% last month.

That data boosted U.S. Treasury yields and the dollar.

"What (the Dow hitting 40,000) means is that regardless of the concerns about inflation and consumer sentiment, the companies in the Dow, which represent a cross section of our economy, continue to march higher on better earnings and stronger guidance," said Quincy Krosby, chief global strategist at LPL Financial in Charlotte, North Carolina.

MSCI's gauge of stocks across the world .MIWD00000PUS rose 0.31 points, or 0.04%, to 794.08, hitting a third straight record intraday high. The STOXX 600 .STOXX index fell 0.21%.

U.S. Treasury yields rebounded from almost six-week lows after the jobless claims data and as Federal Reserve officials said they need to see further progress on inflation before cutting interest rates.

New York Fed President John Williams said the data is not enough to call for the U.S. central bank to cut interest rates sometime soon.

Richmond Fed President Thomas Barkin also said inflation is still not where the Fed needs it to be, while Cleveland Fed President Loretta Mester said holding the central bank's policy at current levels will help get still-high inflation back to the 2% target.
