Adds yield on the new bonds in paragraph 6

MADRID, Feb 25 (Reuters) - Spain raised 7 billion euros ($7.33 billion) on Tuesday in a new 15-year bond sale via a syndication, according to a lead manager memo seen by Reuters.

Demand for the paper maturing on January 31, 2041, exceeded 93 billion euros, three times higher than that obtained in the previous 15-year syndication two years ago, reflecting investors' confidence in the Spanish economy, the Treasury said.

Barclays, Credit Agricole CIB, Goldman Sachs Bank Europe SE, HSBC, Nomura and Societe Generale were picked to sell the bond.

The 3.5%-coupon bond was priced at 99.824, yielding 3.515% after the spread dropped to 9 basis points above Spain's outstanding 15-year debt due on July 30, 2039, from the initial guidance of 11 bps. In the secondary market, the 2039 bond yielded around 2.43% on Tuesday.

Spain raised 15 billion euros last month in a 10-year bond syndication which drew a record demand of about 139 billion euros.
