After a pause of a few months, the world's leading central banks are "printing" money again to try to bolster their economies. Commonly known as quantitative easing or QE, the European Central Bank (ECB) resumed its programme just before the turn of the year.

Negative rates are the destruction of money, an economic aberration based on the mistakes of many central banks and some of their economists who start from a wrong diagnosis: the idea that economic agents do not take more credit or invest more because they choose to save too much and therefore saving must be penalized to stimulate the economy.
