He said: ”Italy needs to favour public and private investment and to contain and reduce public debt.”
The bank governor added the debt must be “put on downward path.”
President Sergio Mattarella, addressing a group at the presidential palace that had marked the 70th anniversary of the constitution, noted that the state’s founding law requires “balanced budgets and the sustainability of debt.”
He said: ”This is to protect the savings of our fellow citizens.”
Matteo Salvini, leader of the League and also a deputy prime minister, responded to Mattarella by saying that years of Brussels-imposed austerity had driven up debt.
Mr Salvini said: ”Be calm Mr. President. Years of budgets imposed by Europe have made our public debt explode… finally we are changing course and betting on the future and on growth.”
Late on Thursday, the ruling parties – made up of the anti-establishment 5-Star Movement and the right-wing League – proposed a 2019 deficit that is, at 2.4 percent of gross domestic product (GDP), three times the previous administration’s target.
The announcement rattled markets on Friday, prompting a sell-off of bonds and a rout of banking stocks. It also set up a clash with the European Commission, which monitors and enforces EU fiscal rules.
Earlier, before either Mr Mattarella or Mr Visco spoke, 5-Star leader Luigi Di Maio said the budget would “repay the people for the thieving of the past”, though he added the government’s intention was not to challenge the EU or financial markets.
The ruling parties pushed Economy Minister Giovanni Tria, who is an economist unaffiliated with either group, to sign off on their plans to hike deficit spending. Italian media said Mattarella had supported Tria’s failed effort to keep the deficit target below 2 percent of GDP.
The president and the central banker have no direct role in making economic policy.
The 77-year-old president can reject a law and send it back to parliament, but he can do so only once. Parliament can then pass it again, unchanged, and he must sign it into law.
