After yesterday’s last minute decision by Italy’s ruling coalition to boost the country’s 2019 deficit to 2.4% of GDP, a number that challenged Brussels and its demands for a deficit no greater than 2.0% and made a mockery of the finance minister’s insistence on a funding hole no greater than 1.6% of GDP, we said that it was only a matter of time before the market freaked out as Italy is now on collision course with Europe, and that time came this morning when traders dumped Italian assets with the bathwater, as Italian equities, bank stocks and bonds all tumbled in unison after deputy premier Matteo Salvini vowed to “press ahead” with the controversial budget plan including a deficit that would be three times larger than the deficit under the previous administration.
