Storing cash = savings account. You can't physically store cash at a bank, unless he means storing it in a safety deposit box.
It is meant the savings account. Cash is more likely to be stored privately in a safe.
The first message has nothing to do with interest rates, but for storing cash / withdrawal cash.
When you have a business you have pay for both storing cash and withdrawal cash.
When you are a person this normally is free (sometimes only a few times per year)
But this is the case for many years now.
Thank you for the answer. Then this is not news, but something normal. I thought there was a major change and that worried me.
A lot of European banks are now introducing negative interest rates on savings accounts, all related to the fact that they're forced to pay the ECB for storing funds.
