The DBRS thus confirmed the Portuguese sovereign debt at 'A' (low), with a stable outlook, justifying that "external risks to economic performance are balanced due to the persistent improvement of the main public finance metrics".

In August last year, DBRS upgraded the Portuguese debt rating from 'BB (high)' to 'A (low)'.

The next agency expected to pronounce on Portugal is S&P, on March 10.

DBRS looks back at Portuguese debt on July 21.

The 'rating' is an evaluation attributed by the financial rating agencies, with a great impact on the financing of countries and companies, since it assesses the credit risk.
