(ANSA) - Rome, August 10 - Italian and Spanish bonds came under renewed pressure Friday as their spreads between the German benchmark widened on the day. The spread between Italian 10-year bonds and the German bund rose to 450 basis points. The yield, an important indicator of investor confidence in Italy's ability to weather the debt crisis, was 5.88%. The Spanish spread closed at 546.2 points. Earlier in the day New York-based ratings agency Fitch said it was "cautious" about a recent European bailout to Spain's troubled banks, sending an uninspiring signal to international investors.
