KB Securities, the brokerage arm of KB Financial Group, has entered a three-party memorandum of understanding with regulated tokenization platform Securitize and the Optimism Foundation. The agreement, signed on September 23, 2026, aims to develop and distribute tokenized securities for domestic institutional investors in South Korea, beginning with products issued on OP Mainnet, the Ethereum Layer-2 network operated by Optimism.

Under the arrangement, KB Securities will handle product structuring, issuance and distribution through its institutional client network. Securitize will supply the tokenization infrastructure, compliance framework, fund administration and ownership record-keeping. The Optimism Foundation will provide the blockchain settlement layer on OP Mainnet along with technical integration and commercialization support.

Initial Focus on Money Market and Asset Management Strategies

The first phase centers on institutional liquidity products. Plans call for a tokenized money market fund recorded as tokens on OP Mainnet rather than a traditional register. A second product will tokenize an investment vehicle linked to a flagship strategy managed by KB Asset Management, the group’s asset-management unit. Specific product names, launch dates and fee structures have not been disclosed.

Later stages of the partnership contemplate tokenized equities, American depositary receipts, corporate debt and South Korean government bonds once the domestic regulatory environment permits. In a subsequent phase, KB Securities intends to examine channels for offering existing global tokenized funds from international asset managers to Korean institutional and wholesale clients.

Regulatory Context in South Korea

The timing aligns with ongoing work by South Korea’s Financial Services Commission on rules for security token offerings and blockchain-based issuance. Under the commission’s three-stage roadmap, selected privately pooled money market funds and institutional bonds are expected to become eligible when amended securities rules take effect on February 4, 2027. Subsequent stages would extend the framework to publicly offered securities and later link settlement to stablecoin-based payments. Licensed financial firms are expected to be able to handle tokenized securities within the scope of their existing licenses.

KB Securities held approximately $56 billion in total assets and roughly $5 billion in shareholders’ equity as of December 2025, according to company figures. The firm operates across six countries, including the United States.

OP Mainnet’s Role and Broader Institutional Activity

OP Mainnet was selected for the initial money market fund issuance. The network offers low-cost settlement with approximately two-second block times and full compatibility with the Ethereum protocol. Securitize already manages more than $5 billion in tokenized assets and administers BlackRock’s BUIDL tokenized Treasury fund, which expanded onto OP Mainnet in November 2024 as part of a multi-network deployment.

Real-world asset totals on OP Mainnet stood near $39 million at the time of the announcement, with Securitize accounting for about $26 million. Secondary transfer volumes have remained limited, indicating that most activity to date has come from primary allocations rather than active secondary trading.

The memorandum of understanding establishes direction and division of responsibilities rather than a live product schedule. Success will depend on regulatory progress, institutional demand for the initial funds, and the eventual development of secondary market activity on the chosen network.
