JPMorgan plans to launch a Chase-branded digital bank in Germany by the end of this year or early next year. Mr. Dimon, JPMorgan's chief executive, plans to reach major European economies and secure enough customers to build a new profit engine. JPMorgan previously launched Chase in the UK in 2021. Setting up a digital bank from scratch is taking longer and more complicated than JPMorgan expected, according to people familiar with the matter. Chase is understood to have hoped to launch in Germany in 2022, but the launch date has been delayed due to a series of delays.
