Bloomberg Expands Partnership with Graubündner Kantonalbank to Modernize Investment and Sustainability Reporting | LeapRate
Graubündner Kantonalbank (GKB), a major Swiss cantonal bank, has adopted a broader suite of Bloomberg’s Buy-Side Solutions to strengthen its investment operations, quantitative research and sustainability reporting capabilities.
The bank, a long-time user of the Bloomberg Terminal and Bloomberg Indices, will now implement Bloomberg AIM, an order and investment management platform, to streamline front-office workflows including trade execution, order generation and portfolio monitoring. GKB is also expanding its use of PORT Enterprise, giving investment teams access to portfolio and risk analytics integrated directly into daily processes.
Additionally, GKB is adopting Bloomberg’s BQuant Enterprise, a cloud-based analytics platform, to advance its quantitative investment capabilities. The bank is transitioning from Matlab and Excel to the Python-based system, which will support multi-factor investment models with real-time analytics, interactive scoring and backtesting through customized dashboards.
Gian Raffainer, Head Investment Center at GKB, said the expanded partnership strengthens connectivity across investment workflows while supporting quantitative research and sustainability reporting development. He noted the tools allow the bank to manage investment solutions professionally and in its clients’ best interests.
Jose Ribas, Global Head of Buy Side Solutions at Bloomberg, said the combination of BQuant Enterprise, AIM and PORT Enterprise creates a unified workflow for research, monitoring and reporting, helping GKB scale innovation across its investment functions.
Bloomberg’s Buy-Side Solutions offer multi-asset capabilities spanning the investment lifecycle, including research management, execution, portfolio analytics and compliance tools, all integrated with the Bloomberg Terminal.
As of December 2025, GKB manages roughly USD 18 billion in assets across its investment solutions.
