How a Canadian banking giant’s acquisition of an American institution created an attractive cross-border banking platform for international entrepreneurs, corporations, and commodity traders.
In international finance, finding the right bank can be just as important as choosing the right corporate jurisdiction.
For companies operating across borders, banking relationships determine far more than where cash is deposited. They influence access to U.S. dollars, international payments, trade finance, credit facilities, and opportunities for expansion.
That is what makes the combination of Bank of the West and Bank of Montreal (BMO) particularly interesting.
When BMO completed its US$13.8 billion acquisition of Bank of the West from France’s BNP Paribas on February 1, 2023, it dramatically expanded its American banking presence.
The former Bank of the West customers were integrated into BMO’s U.S. banking platform in September 2023. The Bank of the West name has largely disappeared, but its American banking relationships and commercial expertise became part of a much larger North American institution.
For the right internationally structured business, the result deserves serious consideration.
A Canadian Banking Giant With American Reach
Founded in 1817, Bank of Montreal is Canada’s oldest bank and one of North America’s largest financial institutions.
By July 31, 2026, BMO Financial Group reported approximately C$1.5 trillion in total assets.
Its American commercial banking business operates primarily through BMO Bank N.A., an FDIC-insured U.S. national bank.
The Bank of the West acquisition originally added nearly 1.8 million customers and more than 500 branches and commercial and wealth management offices, significantly expanding BMO’s presence in California and other Western U.S. markets.
BMO has since rationalized parts of that network, including the September 2026 sale of 138 U.S. branches to First Citizens Bank.
But the strategic advantage remains: BMO combines a substantial Canadian banking franchise with an established American commercial banking platform.
That combination is especially valuable for businesses with legitimate operating requirements in both countries.
The Offshore Banking Advantage
First, an important distinction.
BMO Bank N.A. is not an offshore bank in the traditional tax-haven sense. It’s a regulated American bank, operating under U.S. law. Likewise, a Canadian BMO account is subject to Canadian banking regulation.
However, for a company headquartered outside the United States, maintaining an American bank account can represent an offshore banking relationship relative to its home jurisdiction.
This is where BMO’s international capabilities become attractive.
Consider a Canadian company with a U.S. subsidiary, American customers, international suppliers, and revenues denominated in U.S. dollars.
Rather than relying exclusively on cross-border wires from a Canadian institution, that company may benefit from a properly established U.S. banking relationship, with access to domestic payment systems and commercial banking services.
BMO can potentially serve both sides of that corporate structure through its Canadian and U.S. operations, subject to separate account approvals and applicable regulations.
For a company operating internationally, that is a practical advantage—not a secrecy strategy.
Five Reasons BMO Deserves a Place on the International Banking Shortlist
1. Access to the U.S. Dollar Economy
The U.S. dollar remains central to global commodity trading, international contracts, commercial finance, and corporate treasury management.
An appropriately structured U.S. business relationship can help a foreign-owned enterprise manage American receivables, pay domestic suppliers, and maintain dollar-denominated operating balances.
For businesses conducting significant USD transactions, reducing unnecessary currency conversions and simplifying payment flows can deliver meaningful operating efficiencies.
2. Two Banking Jurisdictions, One Financial Group
The distinction between a U.S. account and a Canadian account can be strategically useful.
A business may require Canadian-dollar operations for its Canadian activities while maintaining U.S.-dollar accounts for an American subsidiary or customer base.
BMO has dedicated cross-border commercial banking teams assisting businesses with expansion, receivables, payables, and financing requirements on both sides of the border.
Although accounts remain subject to the rules of their respective banking entities, an integrated relationship may offer better coordination than managing entirely unrelated banks.
3. Trade Finance for International Commerce
This may be BMO’s most overlooked advantage.
For companies importing machinery, exporting agricultural products, purchasing raw materials, or financing industrial projects, conventional checking accounts are only the beginning.
BMO offers international trade finance and risk management services, including support involving letters of credit and standby letters of credit.
Its Canadian commercial banking division reports trade-finance relationships involving more than 200 banks worldwide.
For established businesses with verifiable contracts, credible counterparties, and documented transactions, access to trade-finance specialists can be considerably more valuable than an ordinary offshore deposit account.
4. Banking Expertise Across Specialized Industries
BMO’s commercial banking platform serves sectors including agriculture, metals, manufacturing, logistics, shipping, technology, commercial real estate, and energy-related industries.
These are precisely the sectors where international banking frequently becomes complicated.
Commodity transactions, for example, may require enhanced verification of product origin, shipping documents, counterparties, and payment instructions.
Working with bankers who understand an industry’s commercial practices can help a properly documented transaction receive an appropriate assessment.
BMO’s industry specialization does not guarantee approval, but it gives suitable businesses a more relevant starting point.
5. Institutional Scale and Deposit Protection
Size alone does not make a bank safe, but institutional scale, regulatory supervision, and access to financial services matter when selecting an international banking partner.
Eligible deposits at BMO Bank N.A. are covered by U.S. Federal Deposit Insurance Corporation protection, generally up to US$250,000 per depositor, per insured bank, per ownership category, subject to applicable rules.
Larger corporate treasury balances require additional consideration because amounts above applicable insurance limits may be uninsured.
For internationally active corporations, counterparty diversification and prudent cash management remain essential.
Who Is the Right Company?
BMO’s cross-border banking proposition is especially compelling for a business that can demonstrate a legitimate economic reason for maintaining Canadian and American banking relationships.
Potential candidates include:
- Canadian companies expanding into the United States, particularly those establishing operating subsidiaries.
- American businesses with Canadian operations, requiring coordinated commercial banking services.
- International commodity traders and distributors with documented USD payments, suppliers, and counterparties.
- Technology, media, and professional-services companies generating cross-border subscription, licensing, or contract revenue.
- Established international companies seeking treasury management, financing, or trade-finance support across North America.
The critical factor is not simply where a company is incorporated. It is the nature of its business, its owners, its transactions, and its banking requirements.
A Nevada corporation, for example, may be a strong candidate if it maintains genuine commercial activity, transparent beneficial ownership, appropriate tax identification, and legitimate U.S. banking needs.
But incorporation alone does not create banking eligibility.
What International Companies Must Understand Before Applying
There is no shortcut around modern banking compliance.
BMO’s business-account documentation includes identification, tax identification numbers, corporate formation records, and beneficial-ownership information. Additional documents may be required.
Foreign ownership, complex corporate structures, unusual transaction patterns, and certain industries may attract additional scrutiny.
Companies should expect to provide clear explanations of their business model, expected transaction volumes, counterparties, and sources of funds.
Importantly, a foreign-incorporated company should not assume that it is automatically eligible for a standard U.S. business account. Eligibility and onboarding requirements must be confirmed directly with BMO.
Nor does offshore banking eliminate tax obligations, reporting requirements, or applicable anti-money-laundering and sanctions controls.
The most bankable international corporation is often the one with the simplest explanation of where its money comes from, why it moves, and where it is going.
The Invest Offshore Perspective: Banking Infrastructure Is a Competitive Advantage
For decades, offshore banking was often marketed around privacy, asset protection, and geographic diversification.
Those subjects remain relevant, but the most valuable modern banking relationships deliver something more practical: the ability to operate internationally with dependable financial infrastructure.
BMO’s combination of Canadian financial heritage, an expanded American banking presence, and international commercial capabilities makes it a compelling candidate for companies building legitimate cross-border operations.
Bank of the West’s legacy is especially significant because it helped expand BMO’s reach into the American West, strengthening a commercial banking network connected to major North American markets.
For an internationally minded corporation, access to the right relationship manager, treasury platform, and trade-finance team can make an enormous difference.
The key is selecting the bank according to the business—not creating a business merely to obtain a bank account.
Final Word: The Right Bank for the Right Structure
The acquisition of Bank of the West was more than a consolidation of banking assets. It helped build a broader North American financial platform under BMO.
For the right company, particularly one conducting legitimate business in both Canada and the United States, this combination can provide an attractive alternative to relying solely on traditional offshore financial centres.
It offers the potential for a strong U.S. banking presence, Canadian connectivity, international trade-finance expertise, and access to substantial commercial banking resources.
That does not make BMO the right bank for every offshore company.
But for a well-structured, transparent, internationally active enterprise, it makes BMO a bank worth investigating.
The future of offshore banking may be less about finding an obscure jurisdiction and more about building the right international banking relationships.
