A deeper examination of why the consultation’s suggested deferral is incongruous within a rules-based benchmark and what a more effective approach might entail.
JPX Market Innovation & Research (JPXI) is contemplating a new regulation that would postpone the inclusion of companies whose primary asset is cryptoassets into TOPIX and other periodically evaluated indices. The proposal is temperate in its language, and the underlying apprehension, concerning how to categorize a nascent class of issuers, is a justifiable consideration for any index provider.
However, the specific regulation under review presents significant questions. It would impact entities such as Metaplanet, Remixpoint, and ANAP Holdings, along with an increasing number of Japanese companies whose operational frameworks are entirely compliant, fully regulated, and perfectly aligned with established corporate treasury methodologies.
Here are seven compelling arguments for JPXI to reconsider its proposal before February 2026.
1. The Rule Deviates from TOPIX’s Standard Measurement Criteria
TOPIX is intended to serve as a comprehensive, impartial, and investable gauge of the Japanese equity market. Its existing methodology incorporates objective instruments for this purpose, including liquidity assessments, market capitalization adjusted for free float, continuation buffers, and established protocols for delistings and other significant listing events.
A screen based on cryptoassets represents a different type of evaluation. It does not assess liquidity, free float, turnover costs, market capitalization, or listing quality. Instead, it scrutinizes the composition of a company’s balance sheet.
This constitutes a substantial divergence from the historical basis of TOPIX eligibility, warranting a more thorough justification than is currently provided in the consultation. If a company meets TOPIX’s conventional eligibility criteria, excluding it based on a single asset category introduces an unprecedented level of judgment into a methodology valued precisely for its impartiality.
2. A Precise Definition for “Principal Asset Is Cryptoassets” Is Lacking
The consultation refers to entities whose “principal asset is cryptoassets,” but leaves several practical ambiguities unresolved:
- Does the assessment consider holdings of the parent company exclusively or consolidated group holdings?
- Would exposure through wholly owned subsidiaries, associated firms, or strategic equity investments be encompassed?
- Would indirect exposure via securities, derivatives, or instruments with similar economic characteristics qualify?
- Is the inquiry focused on the formal aspect (direct legal ownership) or the substantive aspect (economic exposure)?
These are not minor technicalities. They are critical in determining the scope of the rule’s application. The credibility of an index methodology hinges on rules that are objective, quantifiable, and uniformly applicable, and a more precise definition would benefit all parties: the issuing companies, investors, and JPXI itself.
3. The Rule May Be More Susceptible to Circumvention Than Application
A practical challenge emerges from the definitional ambiguity. If direct holdings of Bitcoin by the parent entity are disfavored, while equivalent exposure through alternative structures is not, the rule becomes responsive to legal form rather than economic reality.
Consider the inherent imbalance:
- A direct Bitcoin holding would trigger the rule.
- A holding in the iShares Bitcoin Trust ETF (IBIT) would likely not.
- A stake in a publicly traded Bitcoin mining company would likely not.
- An investment in a crypto-affiliated subsidiary would likely not.
The economic exposure in these scenarios can be highly comparable, yet the index treatment would differ significantly. This creates an incentive for companies to restructure towards less transparent forms of exposure rather than openly reporting direct holdings on their balance sheets. A benchmark regulation typically functions more effectively when it encourages clear reporting rather than its opposite.
4. The Exemption for Existing Constituents Creates Internal Inconsistency
The consultation proposes deferring new inclusions while exempting current constituents from the rule. While this is understandable from a perspective of maintaining stability, as no one desires unnecessary index fluctuations.
However, it introduces an internal logical tension within the rule. If holding Bitcoin on treasury constitutes a genuine incompatibility with TOPIX, it becomes difficult to rationalize exempting current members. Conversely, if such holdings are not incompatible, it raises the question of why new entrants meeting the same investability criteria should face differential treatment.
Resolving this asymmetry would significantly strengthen the proposal.
5. The Phrase “For the Time Being” Indicates an Unspecified Duration
The consultation states that the deferral would be in effect “for the time being,” without defining a review period, an exit criterion, or a sunset clause. In practice, this renders the timeline indefinite.
The timing is crucial here. October 2026 marks the first periodic review under the next-generation TOPIX framework, under which companies in the Standard and Growth markets can become eligible through the new process. A deferral that coincides with this review, lacking a defined pathway back to eligibility, could effectively operate as a long-term exclusion, even if not explicitly framed as such.
A more defined review schedule or an explicit sunset provision would facilitate a more objective evaluation of the proposal’s merits.
6. Global Counterparts Have Adopted a More Measured Approach to the Same Issue
JPXI is not the sole index provider grappling with this challenge. MSCI recently explored a threshold-based approach for treasury companies dealing in digital assets and ultimately opted against a broad exclusion, acknowledging the need for further analysis to differentiate operating companies from non-operating or investment-like entities. FTSE Russell has not introduced a comparable regulation.
The common theme is that the classification issue remains genuinely unresolved. Operating companies holding Bitcoin alongside other business activities—such as media, energy, retail, mining, or infrastructure—do not fit neatly into existing categories, and the global index community is still in the process of formulating its approach.
In light of this, there is a reasonable basis for JPXI to engage further with issuers and market participants before formalizing a rule, rather than preceding the broader industry consensus.
7. An Asset-Agnostic Framework Would Offer Greater Longevity
If the underlying concern relates to certain listed companies becoming overly concentrated or investment-focused, this concern merits attention but is not exclusive to cryptoassets. Concentrated holdings can manifest in various forms, including listed equities, stakes in private companies, fund interests, real estate, or other non-operating assets.
A framework that applies uniformly across these categories would likely prove more enduring than a rule targeting a single asset type. It would also circumvent the definitional and arbitrage issues previously mentioned, as the test would focus on the economic characteristic of actual concern to JPXI, rather than a specific asset class.
Several avenues could achieve this:
- Enhanced reporting standards for concentrated treasury positions of any nature, providing investors with clarity without altering index composition.
- An asset-neutral concentration framework that applies a consistent test to any non-operating asset held above a specified threshold.
- An optional index variation for investors seeking exposure to the Japanese market with cryptoasset-heavy companies excluded, offered supplementary to, rather than in place of, the primary benchmark.
Implications for the Current Proposal
None of this suggests that JPXI’s inclination to carefully consider a new category of issuer is misguided. It is not. Companies with Bitcoin on their balance sheets are a relatively recent phenomenon, and their increasing visibility in Japan has accelerated the need to seriously address questions surrounding their treatment.
However, the specific rule under consultation is more restricted, less precise, and more open-ended than the issues it aims to resolve. A more defined scope, a fixed review period, and an asset-neutral framing would significantly contribute to addressing the underlying concerns while preserving the qualities that have established TOPIX as a trusted benchmark: objective, rules-based eligibility that accurately reflects the current Japanese equity market.
This approach—prioritizing substance over form, clarity over ambiguity, and neutrality across asset classes—appears to be the more robust path forward.
