LONDON, May 21 (Reuters) - Euro zone bond yields were little changed on Tuesday as investors awaited wage and survey-based growth data later in the week for a steer on the outlook for interest rates.

The German 10-year bond yield, the benchmark for the euro zone bloc, fell 0.8 basis points (bps) to 2.52%.

Italy's 10-year yield was steady at 3.81%, and the gap between Italian and German bond yields held steady at 128 bps.

The spread between U.S. 10-year Treasuries and German bond yields was flat at 191 bps.

Germany's two-year bond yield, which is more sensitive to European Central Bank rate expectations, was little changed at 3%. (Reporting by Harry Robertson; Editing by Lincoln Feast)
