The basic rules of ring-fencing are that deposits from UK individuals and small businesses must be placed inside the ring-fence. Most exposures to financial institutions and trading activities must be placed outside the ring-fence. Some activities, notably banking for larger companies, may be on either side of the ring-fence. To comply with these rules, banks will need to move some customers into a new part of the bank. Different customers will be affected in different ways. Some customers will experience changes to their account details. For example, they may be issued with a new sort code and/or their bank account number may change. Payments sent using old account details will be rerouted to their intended destination, using automatic redirection facilities. Each bank will be communicating with its own customers about ring-fencing and how it will affect them. It is important that people take all the usual precautions when dealing with requests from businesses and banks to provide personal or financial information. These precautions include never disclosing security details such as PINs or full banking passwords, not automatically clicking on links contained in unsolicited emails, and not assuming an email or phone call is authentic.
