Talk of high street banks imposing negative rates in UK ramping up

This has been out for a few hours now (overnight). RBS and NatWest both warning of negative rates

(note - Royal Bank of Scotlsand owns NatWest)

RBS letter to customers:

• "Global interest rates remain at very low levels... this could result in us charging interest on credit balances"
• "We will consider any necessary action in the event of the Bank of England base rate falling below zero, but will do our utmost to protect our customers from any impacts"

The threat information is directed at business customers, not personal customers
