7 Reasons JPX Should Reconsider Its Proposed Digital Asset Issuance From TOPIX

A closer look at why the proposed deferral of consultation sits uncomfortably within the rules-based benchmark – and what a better way forward might look like.

JPX Market Innovation & Research (JPXI) is considering a new rule that would exclude companies whose main assets are cryptoassets from new inclusion in TOPIX and other indexes that are updated from time to time. The proposal is measured by tone, and the basic concern – how to manage the emerging class of issuers – is reasonable for any index provider to think about.

But the specific legislation under discussion raises real questions. It would affect companies like Metaplanet, Remixpoint, and ANAP Holdings, as well as a growing set of Japanese issuers whose business models are fully legal, fully regulated, and fully consistent with long-term corporate finance practices.

Here are seven reasons JPXI should reconsider the proposal before February 2026.

1. The Law Doesn’t Measure How TOPIX Is Averaged

TOPIX is designed to serve as a comprehensive, neutral, investable benchmark for the Japanese equity market. Its methodology already contains objective tools for that purpose – liquidity screens, free-adjusted market capitalization methodology, continuation buffers, and established treatment for delisting and other listing quality events.

A crypto-asset screen is a different type of screening. It does not measure liquidity, free float, cost of ownership, market capitalization, or inventory quality. Instead it looks at the structure of the company’s balance sheet.

That’s a reasonable departure from how TOPIX’s merits have historically worked, and it deserves a clearer justification than the current consultation offers. If a company satisfies the general eligibility requirements of TOPIX, decommissioning it because of one asset class introduces a new type of judgment in the way it is valued precisely because of its discretion.

2. “Cryptoassets” Needs a Clear Definition

The consultation refers to companies whose “primary assets are cryptoassets,” but leaves several management questions open:

• Is the test based on parenting only or combined holdings?
• Can exposure to wholly owned subsidiaries, affiliates, or strategic equity stakes be held?
• Does indirect exposure through securities, derivatives, or similar financial instruments count?
• Is the inquiry legal (direct legal subject) or substantive (economic exposure)?

These are not crimes. They decide that the law applies to them in companies. The index method derives its credibility from objective, measurable, and uncontrollable rules, and a clear definition can help everyone – issuers, investors, and JPXI itself.

3. The Law May Be Easier to Practice Than to Apply

A practical concern follows the question of meaning. If the direct custody of Bitcoin by the parent company is not preferred, but the equivalent exposure by other entities is not, the law becomes more serious from a legal point of view than an economic point.

Consider the asymmetry:

• The exact position of Bitcoin can create a law
• A position in the iShares Bitcoin Trust ETF (IBIT) probably won’t
• The position on the list of Bitcoin miner will probably not
• A share in a company owned by crypto-link probably won’t

The economic exposure to these conditions can be very similar. The treatment of the index can be very different. That creates an incentive for issuers to restructure towards more transparent forms of exposure instead of disclosing direct holdings on the balance sheet. Benchmarking legislation generally works better when it encourages clear disclosure than vice versa.

4. Carve-Out of Existing Voters Creates Internal Tensions

The consultation considers deferring new installations while not applying the principle to existing parts. This is understandable from a stability perspective – no one wants unnecessary index churn.

But it also creates internal contradictions in the concept of law. If the exposure to Bitcoin treasury was not really compatible with TOPIX, it would be difficult to justify releasing the current members. And if it doesn’t match, it’s worth asking why new entrants who meet the same investment criteria should be treated differently.

Reconciling that asymmetry will greatly strengthen the proposal.

5. “Currently” Leaves the Timeline Open

The talks say the rollback will be in effect “for the time being,” without specifying the timing of the review, the extent of the rollout, or the sunset method. Actually, that leaves the timeline open.

Time is of the essence here. October 2026 will be the first revision of the periods under the next-generation TOPIX framework in which Standard and Growth market companies can qualify for the new process. Deferrals associated with that review, without a defined path back to eligibility, can serve as long-term exclusions even if not scheduled that way.

A clear review cadence – or a clear sunset – can make a proposal easier to evaluate on its own merits.

6. International Peers Take More Time on the Same Question

JPXI isn’t the only directory provider thinking about this. MSCI recently considered a border-based approach to digital-asset treasury companies and in the end did not accept the exclusion, admitting the need for more work to distinguish active companies from non-active or investment-like entities. FTSE Russell has not announced a similar rule.

The common thread is that the question of segregation has not been truly resolved. Active companies holding Bitcoin alongside other lines of business – media, energy, retail, mining, infrastructure – do not fit well into existing sectors, and the global index community is still adjusting its thinking.

Given that, there’s a strong case for JPXI to continue to consult with issuers and market participants before writing the rule, rather than moving forward where the broader discussion has reached.

7. The Asset Neutral Framework Will Remain Strong

If the underlying concern is that some listed companies are too concentrated or too investment-like, that concern should be addressed – but not limited to cryptoassets. Concentrated holdings may take many forms: listed shares, shares of private companies, fund interests, real estate, or other non-performing assets.

A framework that applies consistently across these categories may be more robust than a single property rule. It would also eliminate the definition and arbitrage concerns above, as the test would focus on the economic aspect that JPXI really cares about instead of a single asset class.

Several methods can do this:

• Improved disclosure standards in fixed treasury positions of any kind, giving investors clarity without changing the composition of the index
• Material neutral focus frame which applies the same test to any inactive material above the specified limit
• A different index option for investors looking for exposure to the Japanese market and cryptoasset heavyweights not listed, offered alongside – not instead of – the flagship brand

Where This Leaves the Proposal

None of this is to say that JPXI’s sense of carefully considering a new output stage is wrong. That’s not the case. Bitcoin finance companies are relatively new, and their prominence in Japan has grown quickly enough that questions about how to manage them should be taken seriously.

But the specific law of reasoning is narrower, vaguer, and more open-ended than the questions it tries to answer. A clear definition, a defined review period, and an asset-neutral framework would go a long way in addressing fundamental concerns while maintaining what has made TOPIX a reliable benchmark: objective, rules-based validity that reflects the Japanese equity market as it is.

That combination – substance over form, clarity over ambiguity, neutrality across all asset classes – seems to be a solid way forward.
