Brazilian financial giant Itaú Unibanco has received conditional preliminary approval to establish a nationally chartered bank headquartered in Miami, a move that would expand the institution’s U.S. presence and further strengthen South Florida’s role as a gateway for Latin American capital.
The Office of the Comptroller of the Currency (OCC) issued the approval on August 14, 2026, for a proposed institution named Itaú Bank, National Association, according to OCC Corporate Decision #1386.
The decision allows Itaú to continue organizing the proposed bank. It does not authorize the institution to begin banking operations.
Miami bank would target Latin American wealth
Itaú Bank, National Association, is expected to operate as a full-service bank from a single Miami location. The OCC filing says the institution would focus on high- and ultra-high-net-worth individuals with Brazilian and broader Latin American connections.
Its proposed products and services include:
- Deposit accounts.
- Mortgages and other loan products.
- Credit cards.
- Fiduciary and wealth-management services.
The bank would also be able to enter arrangements with affiliated broker-dealer subsidiaries to maintain and expand existing client relationships, according to the OCC decision.
The proposed structure is designed to add products that Itaú’s existing U.S. affiliates do not currently offer. The bank would not initially build a traditional branch network.
The OCC approved the charter application along with requests for fiduciary powers and waivers of certain director residency and citizenship requirements. The application was sponsored by Itaú Unibanco, S.A., and Itaú Unibanco Holding S.A., based in São Paulo.

Preliminary approval is not permission to open
The OCC’s action is an important regulatory milestone, but several steps remain before Itaú Bank can serve customers.
The proposed bank must obtain approval from the Federal Reserve Board and the Federal Deposit Insurance Corporation (FDIC). The OCC decision states that final approval will not be granted unless those agencies act favorably on the required applications.
The bank must also apply for stock in a Federal Reserve Bank and obtain federal deposit insurance. Itaú has separately disclosed that the bank cannot begin operations until those approvals and other regulatory and operational requirements are complete. The company’s market disclosure is available through Itaú Unibanco’s investor-relations filing.
The OCC retains the authority to modify, suspend or rescind the preliminary approval if circumstances change before final authorization.
That distinction is significant. A preliminary conditional approval permits organizers to take steps toward forming the bank, but the institution cannot conduct the business of banking until it satisfies the preopening checklist and receives final approval from the OCC.
Proposed bank must open with $507 million in capital
The OCC requires Itaú Bank to have at least $507 million in initial paid-in capital, net of organizational and preopening expenses.
The proposed capitalization would involve the contribution of 100% of the ownership interests of Banco Itaú International, a Miami-based Edge Act corporation, to the new bank through Itaú’s U.S. holding-company structure. The OCC has also required additional approvals tied to that capitalization and the proposed business combination.
During its first three years of operation, the bank must maintain a Tier 1 leverage ratio of at least 8%. It must also notify the OCC in advance of significant changes to its business plan or operations and obtain a written determination of no objection before making those changes.
The OCC decision includes additional oversight requirements for senior executive officers and directors. Before certain appointments are made, the proposed bank must submit required information to the agency and receive a letter of no objection.

Technology and security requirements remain
The proposed institution must also demonstrate that its technology and control systems are ready for a regulated banking environment.
Before the OCC conducts its preopening examination, Itaú Bank must submit a detailed description of its final information-systems and operations architecture. That submission must cover vendor due diligence, electronic-banking security, information-systems personnel, internal controls, audit plans, customer authentication and verification, and business-resumption procedures.
The bank must complete an independent security review and testing of its electronic-banking platform. The review must evaluate protection against unauthorized access, cyberattacks, viruses, denial-of-service attempts and other forms of electronic intrusion.
It must also establish a customer-information security program that complies with federal interagency guidelines.
These requirements reflect the practical work still ahead. Organizers must build the bank’s operational infrastructure, finalize policies, establish governance controls, satisfy capital conditions and complete examinations before customers can be onboarded.
Approval carries deadlines
The preliminary approval is subject to specific timing requirements.
If the steps needed to secure the bank’s capital are not completed within 12 months of the August 14 decision, the approval will expire. The bank must also open for business within 18 months, unless the OCC grants an extension under what it describes as the most extenuating circumstances.
The OCC said it generally opposes extensions and expects the organizers to proceed diligently.
The deadlines place the proposed bank’s next steps on a defined regulatory clock. However, they do not guarantee that Itaú Bank will open by a particular date. Final authorization depends on the Federal Reserve, the FDIC, the OCC’s review of preopening conditions and the completion of the bank’s own organizational work.
Miami’s role as an international banking center
The proposed charter arrives as Miami continues to attract financial institutions, wealth managers and professional-services firms serving clients across the Americas.
The city’s location, air connections, multilingual workforce and longstanding commercial ties to Brazil and Latin America have made it a natural base for cross-border banking. Brickell, in particular, has developed into a dense financial district with international banks, investment firms, family offices, law firms and accounting practices supporting international clients.
Miami’s expanding financial ecosystem has also been tied to growth in technology, payments and international trade. Recent South Florida developments in fintech and financial infrastructure have reinforced the region’s appeal to institutions seeking access to both U.S. markets and Latin American customers. South Florida Digest has reported on the region’s expanding technology and fintech activity.
Itaú’s proposed national bank would add a major Brazilian institution to that environment. Its focus on high-net-worth customers with regional ties reflects the type of cross-border financial activity that has helped shape Miami’s banking market.
The decision also comes amid continued interest in South Florida from wealthy international residents, investors and businesses. That activity extends beyond banking into real estate, private aviation, trade, technology and professional services.

What happens next
Itaú’s immediate task is to complete the organizational process and satisfy the OCC’s conditions while pursuing the required Federal Reserve and FDIC approvals.
The bank must finalize its capital structure, submit related filings, complete technology and security preparations, establish governance and compliance systems, and demonstrate that it can operate safely and soundly.
Until those steps are complete, Itaú Bank, National Association, remains a proposed institution rather than an operating U.S. bank.
For Miami, however, the preliminary approval is already a notable signal. It reflects the city’s continuing importance to international financial institutions seeking a U.S. base for Latin American wealth and business relationships. If Itaú completes the remaining requirements, its Miami bank could become another significant link between South Florida, Brazil and the broader Latin American economy.
