Anyone who has read Bad Banks by Alex Brummer will understand that comments like those in Will King's latest blog are the tip of the iceberg.

People have lost faith in the banks. They trusted them for generations and now, after the crash and a surfeit of scandals, abuse of position, rip-offs and self-serving behaviour, it's over. Enough is enough.

This loss of trust is visceral and will not be changed by facile advertising and the passage of time. Banks will be UNbundled, not just because fintech competitors can, but because the banks are UNacceptable.

Their IT, ops and business model cannot pivot. Their scale cannot stop this. They are vulnerable.
