MADRID | By Julia Pastor | Spanish public Treasury will have its weekly appointment with investors on Thursday. This time the country will issue bonds with maturities of 5, 10 and 12 years, respectively. There would be nothing unusual about it if international investors’ appetite for the Spanish sovereign debt were usual. However, interests in national treasuries currently reach levels of the 90’s when, before euro’s introduction, those bought Spain’s debt during seven quarters without a break. The institution even considers the possibility of creating 50 years bonds. At this moment, the Spanish 10 years bonds yield under 3.25%. As the summer comes the benchmark debt could stand at around 3%.
