In an interview with CentralBanking.com, Chris Salmon, the executive director banking and chief cashier at the Bank of England, explained that the idea of moving away from paper banknotes is something the central bank is investigating. "It is incumbent on us to look carefully at the choices for substrates," he said. Salmon stressed that no decision has yet been made.
Salmon also shared his experiences of redesigning the £50 note and reported only a "tiny number" of counterfeits have surfaced since the note was introduced in November 2011.
Defending the relevance of the high-value note in an age where electronic transfers are more usual for larger sums, Salmon said the £50 note certainly has a place in payments and savings in the UK. He categorically rejected the idea of a £100 note being introduced in the UK, however.
