NEW YORK, April 30 (Reuters) - U.S. Treasuries yields ended

little changed on Thursday, as a late bout of month-end

portfolio buying erased earlier losses sparked by encouraging

economic data, a day after the U.S. Federal Reserve hinted it

was in no hurry to raise interest rates.

For April, the U.S. bond market booked a losing month, with

yields rising on heavy debt supply and less pessimism about

Europe reducing the safe-haven appeal of Treasuries, German

Bunds and British gilts.

The month ended with a diminished appetite for safe-haven

assets on Thursday, after Greece made its biggest concessions

yet in an effort to clinch a deal with its creditors to avert

bankruptcy reduced safe-haven bids for Treasuries and Bunds.

"There had been a tremendous amount of complacency in the

bond market. Now (NYSE: DNOW - news) it's people removing duration risk off the

table," Mike Cullinane, head of Treasuries trading at D.A.

Davidson in St. Petersburg, Florida, said of the early selling

in bonds.

Thursday's data showing a drop in U.S. jobless claims, a

rise in consumer spending, wage gains and a jump in Midwest

business activity suggested an economic rebound in the economy

following a meek first quarter, when gross domestic product grew

at an annual rate of 0.2 percent.

Thursday's data revived expectations the Fed might consider

ending its near zero rate policy as early as September.

The U.S. central bank on Wednesday acknowledged the economy

had hit a soft patch due partly to a harsh winter.

"The Fed is looking past the first-quarter weakness. It is

on track to raise rates later this year," said John Bellows,

portfolio manager at Western Asset Management Co. in Pasadena,

California.

It is too early to say how strongly the U.S. economy will

rebound. A forecast model from the Federal Reserve Bank of

Atlanta (BSE: ATLANTA.BO - news) on Thursday showed the economy is on course to expand by

0.9 percent in the second quarter.

Against this uncertain outlook, analysts said the bond

market sell-off appeared overdone.

In late U.S. trading, intermediate Treasuries fared worst

among all maturities, with the five-year yield

breaking above 1.50 percent for the first time in six weeks.

The yield on benchmark 10-year Treasury notes

was up almost 1 basis point at 2.042 percent after touching the

highest level in nearly seven weeks at 2.110 percent.

The 30-year Treasury bond yield edged up nearly

1 basis point to 2.750 percent after hitting a seven-week high

at 2.813 percent.

Treasuries fared better than German Bunds as the 10-year

Bund yield hit 0.385 percent, the highest in eight

weeks.
