The spread of the Slovenian 15-year bond on the German bunds, a eurozone benchmark, thus narrowed to 2.12 percentage points, according to data by the electronic exchange MTS.

Slovenia is organising meetings with investors in Amsterdam, Frankfurt, Ljubljana, London, Munich, Paris and Vienna this week in the run-up to a fresh round of borrowing.

The last time Slovenia issued a non-private bond in euros was in March 2011, when it issued a 15-year EUR 1.5bn eurobond at an interest rate of 5.125%.

It has since sought financing on the dollar market and it also issued a EUR 1.5bn three-year bond in euros in November, but that was a private placement.
