Italian and Spanish bond yields hit their highest levels in 14 years, with five-year Italian yields reaching the same level as Spain's in a sign Rome is overtaking Madrid as a key focus of investors' concern about debt sustainability.

Italy's stock index fell 2.5 percent to its lowest in more than 27 months, dragged down by banks that have heavy exposure to Italian debt. European shares hit a 9-month low amid worries that slowing economic growth will make it even harder to overcome the euro zone's debt troubles.

Economy Minister Giulio Tremonti chaired a meeting of the Financial Stability Committee -- made up of representatives of the government, the Bank of Italy, market regulator Consob and insurance authority ISVAP -- a day before Prime Minister Silvio Berlusconi is due to break his silence and address parliament.
