Deutsche Bank (DBKGn.DE) completed the fourth and final phase of its years-long technical integration with Postbank on Monday.
Germany’s largest bank predicted cost reductions in 2023 and 2024 and 300 million euros ($326.52 million) in 2025.
Germany’s largest bank acquired Postbank, with its millions of customers and roots in the postal system, in 2008 during the global financial crisis, but it has struggled to integrate.
The bank merged its IT infrastructure with Postbank clients over the weekend, preventing some customers from using all services.
Deutsche will begin decommissioning Postbank hardware and software, saving money.
