Monument Bank, a challenger bank in the UK, is in talks to raise £200m in private funding before pursuing an IPO on the Nasdaq exchange. The bank, which has already raised £135m from investors, aims to become the bank of choice for professionals and mass-affluent customers in the UK. It has already opened over 60,000 accounts and plans to expand internationally, with banking licenses in Dubai and India. The decision to list overseas would be seen as a blow to the London Stock Exchange.
