In a speech to parliament, commenting on the successful auction of 10- and 30-year government bonds this week, Passos Coelho cited what he said was a "discrepancy" between what investors think about the outlook for Portuguese debt and the credibility of Portuguese budget policy on the one hand, and what is reflected by rating agencies on the other.


He expressed "confidence" that the agencies will make a "correction" in their ratings soon or later.


Portuguese bond yields have been at or near historic lows in recent weeks, along with those of other euro-zone countries.
