To kill two birds with one stone

In mid-February 2020, Denmark's largest bank, Den Danske Bank, introduced negative interest rates for some of their private banking customers.

To to be able to take part in from this, one must, beside living in Denmark:
Have a savings capital of DKR 750,000 if you do not have a Nemkonto at DDB
Have a savings capital of DKR 1,500,000 if you have a Nemkonto at DDB

There must be many Danes with large savings capital, which represents a big cost for DDB to get them to make such a drastic decision. It may be an opportunity for some Danes to make some acquisitions in a heavily price-adjusted stock market and at the same time avoid negative interest rates.
