European Central Bank President Christine Lagarde says new coronavirus-related restrictions on everyday life in the euro zone add to the economic uncertainty, underlining the need for continued easy fiscal and monetary policy.

"New coronavirus-related restrictions currently being introduced across Europe will add to uncertainty for firms and households," she said at a meeting of the G30, a group of financiers, central bankers and academics.

Moreover, Lagarde warned that the Eurozone economy might shrink by between 8% and 12% in 2020 amid the negative impact of the coronavirus pandemic.

Lagarde earlier said that the "mild" scenario for the economic development in the Eurozone in 2020 with a 5% decline in GDP is already "outdated."
