Don't worry, once the inflation caused by the tanking pound kicks in, the BofE will need to raise interest rates a bit.
Also, given the current outlook, it will be a lucky business that has any money to store and move about.
Sorry, jeremy, but since charities often have business accounts, it's also going to be the very people who the marginalised and disenfranchised rely on. For instance, the homelessness chariity attached to our church as a £30K reserve account that covers the 192 bonds that are currently out for the individuals and families who the charity are working with. If the banks decide, en masse, to go down the same route as RBS and Nat West, that £30K pot
could be being eroded by the payment of interest to the relevant bank.
