Last week, the EC has told Italy that it is concerned about its budget deficit plans for the next three years as it deviates from what had been meant in July.
"We call on the Italian authorities to ensure that the budget will be in compliance with the common fiscal rules and look forward to seeing the details of the measures," according to a letter sent by the EC to Italian Economy Minister Tria on Friday.
The benchmark yield on 10-year Italian bonds rose 3.6 percent, its highest level since early 2014.
