“Can a US megabank build a native cloud-core digital retail bank in the UK and then port that stack back to its home market?”
Chase UK is JPMorgan's greenfield digital retail bank in the UK, launched in 2021 as the first Chase-branded consumer bank outside North America. It runs on a modern cloud-native core (Thought Machine Vault) rather than legacy JPMorgan systems, and has been used as the proving ground for the core platform JPMorgan is now migrating its US retail bank onto. Product scope has expanded from current/savings accounts and debit to credit cards and investing (via Nutmeg).
