But this has happened before
STOP THE WORLD - YOU ARE MISSING THE EVIDENCE OF THE PAST
One thing that is missed by all is that a similar event happened at Royal Bank of Canada about 7 years ago. RBC is "the" biggest bank in Canada so it was a very serious matter. I worked for them at the time, although not on the retail side.
The issues and stories about impacts and the overtime working by staff are exactly the same for Natwest as they were for RBC back then.
Yes it damaged the reputation ofg RBC but that was soon recovered. I suspect that some accounts were moved. Looking at the bank now it is one of the safest and well run in the world. it is certainly seems to be skirting the credit crises very well. RBC is impacted but then all banks are impacted.
We need to step back, and realise that this will blow over and life will will go on.
