U.S. 10-year Treasury yields hit six-month highs before steadying as some buyers came back to the market, helping the government sell $24 billion in new three-year notes.

U.S. stocks ended down slightly as the move in bond yields unsettled investors already concerned about an eventual Federal Reserve interest rate hike.

"In the short term, the market is a hostage to interest rates," said Jim Awad, managing director at Plimsoll Mark Capital. "To the extent you have an increase in interest rates that the Fed doesn't control, you're getting an unwanted tightening in the financial markets."

German Bund yields have surged in recent weeks, boosted by optimism that inflation may have bottomed in the euro region, according to some analysts. The move has been exacerbated by investors unwilling to enter the market until the sell-off shows signs of stabilizing.

Benchmark 10-year Treasuries were last up 5/32 in price to yield 2.25 percent, after earlier hitting 2.37 percent.

The stronger tone helped the Treasury auction three-year notes to strong demand at a 1.00 percent yield. Wednesday's $24 billion 10-year note sale and Thursday’s $16 billion 30-year bond sale may be more challenging.

GREEK CONCERNS
