Some of the other items still in red in that version include parts of a hardline immigration policy that would see Italy increase detentions of undocumented immigrants and speed up deportations.
At a business forum on the shore of Lake Como in September a year ago the leaders of Italy's soaring populist parties brushed off suggestions that they wanted to lead their country out of the euro. The top two finishers - the upstart anti-establishment 5-Star Movement and the nationalist League party - have been inching this week toward an alliance that would have a razor-thin majority in Italy's parliament.
Mr. Salvini, speaking on Facebook live, relished the angst.
Borghi called on 5-Star to recognise the need to take on Brussels and got a response from its leader Luigi Di Maio.
Di Maio backed his potential coalition partner, saying the nascent government was "receiving constant attacks, even today by some eurocrats who weren't elected by anyone". The policy programme will probably be published on Thursday, 5-Star said. The League is also pushing an ambitious overhaul of the justice system.
The Maastricht Treaty was the 1992 agreement that, along with the 1957 Treaty of Rome, that formed the constitutional basis of the European Union. European Union officials also are nervously following developments of a proposed Italian referendum on the future of the euro currency and policies aimed at turning away refugees from Africa and the Middle East. It would also be Italy's first all-populist government.
Italian stocks .FTMIB tumbled 2.3 percent while Italy's 10-year bond yield jumped almost 19 basis points to 2.13 percent.
The dollar index .DXY , which measures the greenback against a basket of six other currencies, rose 0.16 percent to 93.365 after rising to 93.632 during the session, its highest since mid-December.
"They are preparing excuses if they can not maintain all their promises, so they want to unleash a battle against the European Union", said Andrea Romano, a lawmaker from the centre-left Democratic party.
Both parties plan to consult supporters over the weekend to see if they back the government pact. "Nobody knows exactly how it will all play out".
The League's support largely is centered in northern Italy, where it backs lower taxes and reining in central government spending, a popular platform in Italy's most productive region. Di Maio has pledged to guarantee a minimum income to the unemployed.
"For small caps, they are not exposed to a lot of the risks that larger caps are facing", McMillan said.
Nicola Pasini, a political scientist with the State University of Milan, said the parties are not a natural fit.
A new Italian government was put on hold on Monday after the leader of anti-establishment Five Star Movement asked President Sergio Mattarella for a few more days to form a coalition with the far-right League.
Salvini and Di Maio have both agreed to drop their own ambitions to be prime minister and are looking for a candidate from outside their parties to enact their program.
