We must be able to safeguard their functioning also in the future. About a week ago, Europe experienced a short hiccup in the Visa payment card network. Even if the technical problem was solved in less than 10 hours, it showed how vulnerable our daily lives have become. When 75% of payments are not working, a lot of uncertainty and losses are created.
The event reminded us that, to ensure resilience, we need parallel safe infrastructures that can be scaled up, if the normal network is failing. Today, we still have cash. If or when cash is no longer used to the extent that it can be easily scaled up, other alternatives will be needed.
