This is how Sweden acts if the country's banks are subjected to a hacker attack

Every week, transactions worth SEK 20 billion are made with debit cards.

But if all digital payments in Sweden are knocked out by a hacker attack, cash remains as the only means of payment.

According to the Riksbank's head of department, Christina Wejshammar, there is a large cash stockpile that can be used in such a crisis situation, and it is rather distribution that can be a problem.

- You do not have to worry about our stock running out, the problem is to get it out in the community and have a capacity for us all to suddenly use cash instead of our cards, says Christina Wejshammar, head of department at the Riksbank.

MSB: Have 2000 in cash at home

If Sweden should actually end up in a situation where parts of the banking system are eliminated, the Swedish Civil Contingencies Agency (MSB) recommends that you have at least SEK 2,000 in cash at home.

- Preferably in different denominations.

It may be that there is no gear either, so you do not have to pay SEK 500 for a liter of milk, says MSB's CEO Camilla Asp.
