The implicit interest rate on ten-year loans to Slovenia rose above the level of 7% beyond which borrowing is considered unsustainable again in recent days in the wake of new downgrades of Slovenia's credit ratings by major rating firms. On top of these came downgrades on some Slovenian banks and state-owned companies.

The surcharge for Slovenian bonds compared to the reference 10-year German bond was 6.29 percentage points today, up from 5.55 percentage points on Thursday.

The yield on the comparable Spanish bond was at 6.97% today, while the implicit interest rate for Italian bonds was 5.93% and for Ireland's 6.17%.
