Bank of the West was a prominent regional bank in the United States, with deep roots stretching back to its 1874 founding in San Jose, California. For decades, it was a familiar name in communities across the Western and Midwestern states. For much of its modern history, the bank operated as a U.S. subsidiary of the French banking giant, BNP Paribas. However, the Bank of the West story reached its final chapter in 2023 when it was acquired by Canada's BMO Financial Group (often known as Bank of Montreal). Following the acquisition, all of Bank of the West's operations, branches, and accounts were merged into BMO's existing U.S. subsidiary, now known simply as BMO. This marked the end of the Bank of the West brand. For investors, its history is a fantastic case study in global banking strategy, the dynamics of mergers and acquisitions (M&A), and how even well-established companies can become strategic assets in a larger corporate game.
Bank of the West's journey is a story of evolution and international ownership. It grew steadily for over a century, building a solid reputation and a strong deposit base. In 1979, it caught the eye of BNP Paribas, one of Europe's largest banks, which acquired it to establish a significant retail banking foothold in the United States. For over 40 years, Bank of the West operated under the BNP Paribas umbrella. This relationship provided the U.S. bank with the financial backing and global reach of a massive parent company. However, it also meant that its ultimate fate was tied to strategic decisions made thousands of miles away in Paris. For a global behemoth like BNP, a regional U.S. bank, even a large one, can eventually be deemed non-core to its primary objectives. This is exactly what happened, setting the stage for one of the biggest U.S. bank deals in recent years.
In late 2021, BMO announced its intention to acquire Bank of the West from BNP Paribas for a staggering $16.3 billion in cash. The deal was finalized in early 2023. From an investor's perspective, this transaction is rich with valuable lessons.
A value investor always asks “Why?” In this case, BNP's decision to sell wasn't a reflection of poor performance by Bank of the West. Rather, it was a strategic pivot.
For BMO, the acquisition was a game-changer. While BNP saw a non-core asset, BMO saw a golden opportunity to dramatically accelerate its U.S. expansion.
