South Korea's Tokenized Securities Roadmap: What the FSC Three-Phase Plan Means for Accounting

South Korea's Financial Services Commission (FSC) has released a formal three-phase plan to build the legal and market infrastructure for tokenized securities issuance. The first phase comes into force on 4 February 2027, when an amended Act on Electronic Registration of Stocks and Bonds takes legal effect. For accounting firms, auditors, and CFOs with South Korean exposure, the roadmap is not a distant policy aspiration: the FSC has committed to filing revisions to subordinate regulations by the end of September 2026, and the stablecoin payment layer planned for phase three will force a fresh look at how tokenized instruments and their settlement assets are classified under IFRS and, for US-reporting entities, under ASC 350-60.

The Three-Phase Structure

The FSC's roadmap is tied to two interlocking pieces of legislation: the amended Capital Markets Act and the Electronic Securities Act. Together, they form South Korea's first formal tokenized securities framework. The phasing is deliberate, designed to let market infrastructure catch up with legal recognition before broadening the scope of eligible instruments.

Phase One: Legal Recognition and Institutional Scope

From 4 February 2027, tokenized securities will be legally recognised as digitised forms of conventional securities under Korean law. The instruments in scope at launch are institutional money market funds, bonds, unlisted stocks, and fractional investment securities. The FSC will work with the Korea Securities Depository (KSD) to build the underlying tokenization infrastructure before the roadmap formally begins.

Fractional investment securities are worth flagging separately. They represent a structural innovation: the ability to divide ownership of an otherwise illiquid asset into smaller tradeable units recorded on a distributed ledger. For accounting purposes, this creates questions about unit-of-account, whether the fraction is itself a security or merely a participatory interest, and how fair value is determined when a liquid secondary market may not yet exist.

Phase Two: Public Offering Expansion

Phase two extends tokenization to all publicly offered securities. The FSC has not yet published a fixed date for this phase; it plans to decide the timeline alongside its September 2026 regulatory filing. The extension to retail-accessible instruments will raise the stakes considerably for disclosure frameworks, since publicly offered securities carry higher investor-protection obligations and more demanding prospectus and ongoing reporting standards.

Phase Three: On-Chain Stablecoin Settlement

The most significant accounting implication is embedded in phase three: the FSC explicitly targets on-chain payment settlement linked to stablecoins. This means that the settlement asset for a securities transaction would itself be a tokenized instrument, not a bank transfer arriving in a conventional nostro account. For any entity reporting under IFRS or US GAAP, the stablecoin leg of a securities settlement is not automatically treated as cash or a cash equivalent. Its classification depends on the stablecoin's legal structure, the rights it confers on the holder, and whether it meets the redemption and liquidity tests set out in IAS 7 or ASC 230.

Accounting and Reporting Implications

The FSC roadmap sits within a fast-moving global context. The International Accounting Standards Board's amendments to IAS 38 brought crypto assets under a fair-value-through-profit-or-loss model, and FASB's ASC 350-60 requires US-GAAP reporters to carry qualifying digital assets at fair value with changes recognised in net income. Both frameworks were written with fungible, exchange-traded crypto assets in mind. Tokenized securities complicate that picture.

Classification Under IFRS

A tokenized bond issued under the Korean Electronic Securities Act is legally a bond. Its accounting classification therefore follows IFRS 9 rather than IAS 38: the instrument is assessed against the solely-payments-of-principal-and-interest (SPPI) test and the entity's business model. If it passes SPPI and is held to collect, it goes to amortised cost. If it fails SPPI, it goes to fair value through profit or loss (FVTPL).

The wrinkle arrives when the tokenized bond is represented by a smart-contract token that may also carry embedded features, such as automatic coupon distributions or programmable redemption conditions, that could cause it to fail SPPI. Auditors and preparers should document the contractual terms of the on-chain instrument separately from its off-chain legal equivalent, because they may not be identical.

For tokenized equity (unlisted stocks are in phase one scope), IFRS 9 again governs classification. The entity can elect FVTPL or, for long-term strategic stakes, fair value through other comprehensive income (FVOCI) with no recycling. The challenge in Korea's case is fair value measurement for unlisted tokenized stocks, where observable market data may be thin. IFRS 13's hierarchy applies: level 3 valuations will be common in early phases, requiring robust documentation and, for auditors, heightened professional scepticism.

Stablecoin Settlement and the Cash Question

Phase three's on-chain settlement layer is where stablecoin accounting becomes directly operational rather than theoretical. If a Korean entity receives a stablecoin as the proceeds of a securities sale, the accountant must immediately ask: is this cash, a cash equivalent, or a financial asset? The answer controls both the balance sheet line and the statement of cash flows presentation.

Under IAS 7, a cash equivalent must be short-term, highly liquid, readily convertible to a known amount of cash, and subject to insignificant risk of change in value. Most stablecoins fail at least one of these tests depending on their reserve composition and redemption mechanics. A fiat-backed stablecoin with daily redemption at par may come close, but a stablecoin backed by a basket of crypto assets will almost certainly not qualify. The IASB has not yet issued specific stablecoin guidance, so preparers must apply existing principles by analogy.

US-reporting entities should also note FASB's ongoing work in this area. FASB's proposed stablecoin cash-equivalent clarification provides useful context for how the board is thinking about the boundary between cash equivalents and digital financial instruments, and the Korean phase-three timeline gives that debate added practical urgency for any group with Korean operations.

Disclosure and Internal Controls

The new framework will require Korean entities, and their foreign parents, to expand disclosures around digital asset holdings. Under IFRS 7, entities must disclose the nature and extent of risks arising from financial instruments, including market risk, credit risk, and liquidity risk. Tokenized securities introduce technology-specific risks, such as smart-contract failure or custody key loss, that do not map neatly onto the existing IFRS 7 disclosure templates. Firms should begin drafting supplementary disclosure policies now, rather than waiting for February 2027.

Internal controls are equally affected. The three-way reconciliation between on-chain ledger balances, custodian statements, and the general ledger is more complex for tokenized instruments than for conventional securities, particularly where fractional holdings are involved. Audit committees should be asking management how sub-ledger data from the KSD infrastructure will flow into ERP systems and how the completeness and accuracy of that flow will be evidenced.

Who Is Affected and When

Immediate Actions Before End-September 2026

The FSC's commitment to file subordinate regulation revisions by the end of September 2026 is the first concrete deadline. For accounting and audit firms advising Korean clients, this is the window to review engagement letters, assess whether new specialist skills (distributed ledger audit, smart-contract review) are needed, and update risk assessments for any clients active in the Korean capital markets. The Korea Securities Depository's infrastructure build is also underway now, and understanding its technical architecture will be necessary for designing audit procedures around completeness and existence of tokenized positions.

The February 2027 Go-Live

Legal recognition on 4 February 2027 is the date when tokenized instruments first appear on Korean balance sheets in quantity. For year-end reporting entities with a 31 December 2027 balance sheet date, the first full-year period of exposure will be 2027. Preparers should ensure accounting policies for tokenized securities are approved by the audit committee and reviewed by external auditors well before year-end, not during the audit fieldwork phase.

Entities in Scope

Korean banks, securities firms, and asset managers are the obvious primary participants. Foreign entities will become affected as phase two extends scope to publicly offered instruments and as international investors seek exposure to Korean tokenized assets. Group treasury teams of multinationals with Korean subsidiaries should map their potential exposure and assess whether existing group accounting policies for digital assets are adequate for tokenized securities, which are a legally distinct category from crypto assets under most existing policy frameworks.

Broader Regional Context

Korea's move is not isolated. The April 2026 announcement that the Ministry of Economy and Finance would pilot tokenized deposits for government operational spending, with a full rollout targeted for Q4 2026, signals that tokenized instruments are moving into the core of Korean public finance, not just capital markets. This matters for accounting firms because government counterparty transactions involving tokenized instruments will need to be reflected correctly in the financial statements of the private-sector entities on the other side of those trades.

The FSC roadmap also echoes similar frameworks in other jurisdictions, from the SEC's proposed transfer agent rules for tokenized securities in the United States to tokenized sukuk settlements in Malaysia. Korea's adoption of a phased, legislatively grounded approach, rather than a sandbox-only model, suggests the country intends tokenized securities to become a mainstream instrument class, not a niche experiment.

Firms tracking South Korea's tightening crypto AML enforcement will recognise that the FSC is building a coherent regulatory stack: AML obligations, capital markets law, and now a tokenization framework are all being developed in parallel. Accounting teams that treat these as separate compliance workstreams risk missing their interdependencies, particularly where on-chain transaction monitoring overlaps with financial statement assertions about completeness and existence.

The G20's broader endorsement of digital asset frameworks and the global direction of travel on stablecoin regulation give the Korean roadmap additional weight. The phase-three stablecoin settlement layer, in particular, will feed into the global debate about whether stablecoins used in regulated securities settlement deserve a bespoke accounting treatment rather than being forced into existing cash or financial-instrument categories. Standard-setters are watching real-world implementations like Korea's to inform that work.

Practical Next Steps for Accounting Firms and CFOs

Chart of Accounts and Policy Review

Start by identifying whether any existing account codes cover tokenized securities. Most firms will find they do not, because tokenized securities sit in the gap between conventional securities (handled by the custody team) and crypto assets (handled by a treasury or digital assets team, if one exists at all). A dedicated account structure, with sub-ledger linkage to on-chain data sources, should be designed before phase one instruments begin trading.

Vendor and Custodian Readiness

The KSD will provide core infrastructure, but firms will also rely on custodians, prime brokers, and potentially digital asset accounting software to aggregate and report positions. Assessing whether current service providers have built or are building KSD-compatible data feeds is a necessary step before February 2027. Digital asset accounting software that cannot ingest tokenized securities data from a Korean depository will not be fit for purpose when the framework goes live.

Auditor Dialogue

External auditors need early warning of any planned activity in Korean tokenized securities. The audit of tokenized instruments requires skills that overlap with, but are distinct from, conventional securities audit: understanding smart-contract logic, assessing on-chain custody evidence, and evaluating fair value inputs for thinly traded instruments. Audit teams that have not begun developing these competencies now will face resource constraints when 2027 fieldwork begins.
