Second, we need to keep in mind why interest rates are so low today. It is not an arbitrary decision of the central bank; it is because the euro area has been in a long and deep crisis where the economy needed low interest rates to recover. And what would happen if we were to raise rates in that environment?
The answer is that it would only push us back into recession, which would mean lower incomes and more job insecurity for everyone. And then, the ECB would have to keep interest rates lower for longer to get the economy back on track. None of this would be in the interests of savers in any country.
