Start of Innovative Banking Services by DOCOMO SMTB and Monex Securities

On August 28, 2026, DOCOMO SMTB Bank and Monex Securities will roll out a new automated deposit service designed to simplify financial transactions for their clients. This collaboration aims to provide a seamless experience for individuals looking to manage their finances more efficiently, reducing the hassle of manual transactions between bank and securities accounts.

What is the Automated Deposit Service?

The automated deposit service functions as a safety net for investors trading through Monex Securities. In instances where clients have insufficient funds for purchases, the service will automatically transfer the necessary amount from their DOCOMO SMTB Bank account. This ensures that trading can continue smoothly without interruptions typically caused by a lack of available funds.

No Additional Fees

Clients can benefit from this service without incurring any additional fees, allowing for hassle-free financial transactions 24/7. However, transactions will be affected during scheduled system maintenance periods.

Online Setup and Management

The process of signing up and configuring these services can be completed online through the dedicated websites of both DOCOMO SMTB Bank and Monex Securities. Importantly, customers who open a bank account with DOCOMO SMTB will have their securities account with Monex Securities preconfigured, eliminating the need for further actions to activate the service. Users can expect an app feature for Monex Securities to be available soon as well.

Simultaneous Account Opening

This new partnership also introduces the ability for customers to apply for both a DOCOMO SMTB Bank account and a Monex Securities account simultaneously. This feature streamlines the application process, making it more efficient and user-friendly. Furthermore, an upcoming function will allow Monex Securities clients to open a DOCOMO SMTB Bank account concurrently.

Benefits of the Partnership

The launch of these features stems from a strategic agreement made in December 2025 between the DOCOMO Group, which encompasses DOCOMO SMTB Bank and Monex Securities, aimed at creating more accessible financial services. The collaboration seeks to leverage each company’s resources and expertise towards implementing a customer-focused banking approach that emphasizes convenience and ease of use.

Previously, users needed to perform manual fund transfers to make trades through Monex Securities, which could be time-consuming and tedious. The new automated service facilitates real-time transactions, automatically providing funds when needed, thus enhancing usability between the two accounts. With DOCOMO SMTB Bank offering a wide range of financial services including deposits, payments, loans, and asset management, it complements Monex Securities’ role as the only securities company in the DOCOMO Group, providing an extensive array of financial products and services.

Additional Benefits with d Card

Integrating the DOCOMO SMTB Bank, Monex Securities, and d Card offers promotional benefits like enhanced point returns on everyday purchases using d Card, which provides an exciting incentive for users.

Drawbacks and Considerations

While these innovations offer smoother operations and convenience, customers should also acknowledge potential risks associated with trading and investment losses, reminding them of the importance of thoroughly reviewing investment materials before proceeding.

Conclusion

As DOCOMO SMTB Bank and Monex Securities continue to strengthen their collaboration, they pledge to deliver a modernized banking experience backed by their technological capabilities and rich product offerings, providing each customer with tailored financial solutions. This initiative not only enhances customer convenience but also marks a progressive step towards innovative and integrated financial services in the industry.
