Eurozone inflation remained in negative inflation territory for the fourth consecutive month, official data said Tuesday, with the European economy impaired by the second wave of the coronavirus.

The EU’s Eurostat data agency said inflation remained at -0.3% in November, way off the official target set by the European Central Bank of just under 2%.

The descent into deflation has put pressure on the European Central Bank (ECB) to draw up further stimulus measures, already at 1.35 trillion euros ($1.58 trillion), and should encourage governments to spend more.

Policymakers worry about falling prices as they can encourage consumers to hold off making purchases in hopes they fall further, which can lead to a spiral of dropping economic activity, employment and prices.

ECB chief Christine Lagarde has already pledged to bolster the economy with fresh stimulus at the central bank’s December meeting.

The first wave of virus cases in March prompted the ECB to roll out its unprecedented bond-buying scheme to keep borrowing costs low and boost the economy. Expectations are that a beefed-up version of the same scheme known as Pandemic Emergency Purchase Program (PEPP) will be on the table at the next monetary policy meeting on December 10.
