SBI Securities and Okasan Securities have entered into an absorption-type split agreement. Under the terms of the deal, Okasan Securities will transfer a significant portion of its "Okasan Online" business to SBI Securities, the industry leader.

The transfer, scheduled to take effect on October 13, 2026, marks a deepening of the existing partnership between the SBI and Okasan groups, who have previously collaborated in the asset management sector.

Scope of the Transfer

The deal focuses primarily on the core retail investment accounts. SBI Securities will take over Okasan Online’s general securities trading accounts, NISA (Nippon Individual Savings Account) accounts, and margin trading accounts. The transfer includes assets under custody, domestic spot equities, investment trusts, open margin positions, and margin collateral.

Notably, several specialized segments will remain with Okasan Securities and are excluded from this agreement. These include exchange-traded FX (Click 365) and CFD (Click 365) services, over-the-counter (OTC) FX, Chinese equities, and equity crowdfunding (ECF) services.

Strategic Rationale

The decision reflects a strategic pivot for Okasan Securities. The firm indicated it intends to concentrate its internal resources on its core strength: face-to-face consulting and digital integration for its high-touch services. By migrating its online-centric accounts to SBI Securities, Okasan ensures its digital-first customers gain access to SBI’s massive scale and robust technological infrastructure.

For SBI Securities, the acquisition further strengthens its dominant market share in the domestic online brokerage space, adding a new pool of active retail investors and NISA participants to its platform.

Impact and Next Steps

Both companies have stated that the financial impact of this transaction on their respective earnings is expected to be minimal.

In a joint statement, the companies emphasized their commitment to a smooth transition: "Through this transfer, we aim to realize the best interests of our customers and continue to support the asset formation of individual investors."

Okasan Online customers can expect to receive detailed instructions regarding the suspension of certain services and the specific migration process to SBI Securities via a dedicated website in the coming months.
