Though Italy's proposed deficit is within the limit at 2.7 percent of GDP, the country fell short on reducing its large debt pile from past years. Italy had applied for an exemption for spending on long-term investment projects co-funded by the EU and aimed at increasing growth but the commission turned that exception down.
Italian Economy and Finance Minister Fabrizio Saccomanni insisted that the country took the prescribed limits seriously and that debt had risen in part because of measures to pay down debt owed by local governments.
He said new sources of revenue such as privatizations would improve the debt picture and allow Italy to qualify in the end for the investment exemption.
"It is not necessary to change the budget," he said. "We know that it is necessary to send a strong signal."
The commission predicted Spain would have a deficit of 5.9 percent of economic output, just above the agreed target of 5.8 percent. Spain's Finance Minister Luis de Guindos said that "Spain is absolutely committed to the public deficit target" and predicted it would reach it in the end with measures already approved.
The EU rules, on paper, limit countries to deficits of 3 percent of annual economic output and debt of 60 percent of output. They were widely violated during the debt crisis that began in 2009, so the Commission has been pressing countries to get their finances in order but trying not to push so hard that austerity hurts economic growth.
The rules, which date to before the introduction of the euro in 1997, were toughed in 2011 and 2013 after debt levels grew to unmanageable levels in several eurozone countries, threatening the currency union with breakup.
If countries wind up actually breaking the rules, the commission can put them on a recovery plan, called an excessive deficit procedure, that aims to gradually guide them back to full compliance. Thirteen of the eurozone's 17 members are currently on such a plan. If the violations persist, financial penalties of up to 0.2 percent of GDP are possible.
Countries that piled up so much debt they had to be bailed out with the help of the other eurozone countries were not included in the review. That is because they are already subject to EU monitoring. They are Ireland, whose financial support ends Dec. 15, Cyprus, Portugal and Greece.
