This is very interesting, basically banks are going to be punished for not taking a risk with investor money, even before it's measured in real terms.The European Central Bank (ECB) has lowered its benchmark interest rate to 0.15% from 0.25% in an effort to stimulate economic growth and avoid deflation in the eurozone.
It has also reduced its deposit rate below zero, to -0.1%, which means commercial banks will have to pay to lodge their money with the central bank, rather than receive interest.
This means in real terms, you are going to be punished if you don't take risk with any savings.
The issue here, or rather as I see it, is that you've got some very different economies, with very different stages of economic cycle, and very different control requirements all shorehorned together.
Thankfully we never joined the euro!
