7 Reasons JPX Should Reconsider Its Proposed Digital Asset Exclusion From TOPIX
A closer look at why the consultation’s proposed deferral sits awkwardly inside a rules-based benchmark and what a better path forward might look like.
JPX Market Innovation & Research (JPXI) is considering a new rule that would defer companies whose principal asset is cryptoassets from new inclusion in TOPIX and other periodically reviewed indices. The proposal is measured in tone, and the underlying concern, how to treat a newly emerging category of issuer, is a reasonable one for any index provider to think about.
But the specific rule under consultation raises real questions. It would affect companies like Metaplanet, Remixpoint, and ANAP Holdings, along with a growing set of Japanese issuers whose business models are fully legitimate, fully regulated, and fully aligned with long-standing corporate treasury practices.
Here are seven reasons JPXI should reconsider the proposal before February 2026.
1. The Rule Doesn’t Measure What TOPIX Normally Measures
TOPIX is designed to function as a broad, neutral, investable benchmark of the Japanese equity market. Its methodology already contains objective tools for that purpose: liquidity screens, free-float-adjusted market capitalization criteria, continuation buffers, and established treatment for delistings and other listing-quality events.
A crypto-asset screen is a different kind of test. It doesn’t measure liquidity, free float, turnover cost, market capitalization, or listing quality. It looks instead at the composition of a company’s balance sheet.
That’s a meaningful departure from how TOPIX eligibility has historically worked, and it deserves a clearer justification than the consultation currently provides. If a company satisfies TOPIX’s ordinary eligibility requirements, deferring it because of one category of asset introduces a new kind of judgment into a methodology that has been valued precisely for its objectivity.
2. “Principal Asset Is Cryptoassets” Needs a Clearer Definition
The consultation refers to companies whose “principal asset is cryptoassets,” but leaves several administrative questions open:
Is the test based on parent-only holdings or consolidated holdings?
Would exposure through wholly owned subsidiaries, affiliated companies, or strategic equity stakes be captured?
Would indirect exposure through securities, derivatives, or economically similar instruments count?
Is the inquiry formal (direct legal title) or substantive (economic exposure)?
These aren’t edge cases. They determine which companies the rule actually applies to. Index methodology gains its credibility from rules that are objective, measurable, and consistently administrable, and a clearer definition would help everyone: issuers, investors, and JPXI itself.
3. The Rule May Be Easier to Work Around Than to Apply
