Bank of the West was a regional financial services company founded in 1874 and formerly headquartered in San Francisco, California. It provided a wide range of banking products and services, including personal banking, small business banking, commercial banking, and wealth management. In February 2023, Bank of the West was acquired by BMO Financial Group (Bank of Montreal). Consequently, Bank of the West's operations, branches, and customer accounts have been fully integrated into BMO. This page provides historical information and details pertaining to Bank of the West prior to and during its transition into BMO.
Served as the primary administrative and strategic center for all Bank of the West operations, including executive leadership, corporate strategy, risk management, and major departmental oversight before the BMO acquisition.
The headquarters was situated in a prominent building within San Francisco's financial district, reflecting its status as a significant regional bank. It housed modern office facilities typical for a large financial institution.
Bank of the West aimed to foster a customer-focused and community-oriented work culture. It emphasized teamwork, diversity, and inclusion. Post-acquisition, employees have been integrated into BMO's work culture.
The San Francisco headquarters was historically significant as the command center for a bank with a strong presence in the Western and Midwestern United States, guiding its growth and community impact for many years.
As a U.S. regional bank, Bank of the West's direct global presence was limited. However, prior to its acquisition by BMO, it was a subsidiary of BNP Paribas, a large international banking group headquartered in Paris, France. This affiliation provided Bank of the West and its customers with access to a global network and international banking capabilities. Post-acquisition, its global connections are now through BMO Financial Group, which has operations in Canada, the U.S., and select other international markets.
