Portugal rating five and a half years after the S & P rose to return to investme

On Friday, Standard & Poor's took the lead in transferring the Portuguese credit rating to the investment grade in the three rating agencies, referring to improvements in the country's economy and public finances.

Portugal lost its investment grade rating in January 2012 when the debt crisis was most severe.

At present, when the positive impact of the European Central Bank debt measures gradually faded, this adjustment may attract more securities investment funds to the Portuguese bonds.

"At the moment we expect that the spreads of bonds in Portugal and most European countries will be narrow, which is important for investors as they are very concerned about spreads and sometimes more than real yields, Portuguese Finance Minister Mario Centeno told Reuters.

"We are now ready for the future changes in European monetary policy," he added.

In January 2012, after the S & P's rating, Portugal completely lost the three rating agencies at the investment level, driving the Portuguese index 10-year bond yields soared to more than 17% record highs.

Since then, due to the improvement of Portugal's own situation, coupled with the European Central Bank debt plan to help, the yield has dropped to about 2.8%, but still the second highest in the euro area, second only to Greece.

S & P is Portugal's rating to a higher level from the lowest investment level "BBB-", the outlook is still stable; the original rating given to Portugal is "BB +", stable outlook.
