The head of the ECB made a comment on the state of the Eurozone economy, saying that he was concerned about the decline in growth in Europe. Draghi said that the ECB is ready to use all of its resources to support growth in the Eurozone, including even the possibility of a new launch of the QE program (a program to inject liquidity into the markets). Note that the previous liquidity injection program in the huge amount of 2.5 trillion euros was completed only in December 2019.
The ECB's main rate is zero, the deposit rate minus 0.4% is a very long time ago.
