Key Takeaways
  • • JPX's index provider passed over Metaplanet for inclusion in TOPIX despite its new eligibility, highlighting a rift between Japan Exchange Group (JPX) and the crypto-asset industry, according to Toyo Keizai Online.
  • • Index calculators are reportedly excluding companies whose crypto-asset holdings exceed 50% of their business, per the analysis.
  • • The analysis argues that inflating corporate value by accumulating Bitcoin and other crypto-assets on balance sheets will no longer be viable as the crackdown on digital asset treasury (DAT) companies intensifies.
  • • Pending domestic legal amendments and tax revisions allowing Bitcoin ETFs to trade in securities accounts could redirect proxy demand away from crypto-holding operating companies toward legitimate financial products.
  • • Custodians and trust banks are identified as the likely beneficiaries, while treasury companies lacking core business substance face potential NAV erosion and exclusion from passive flows.
Summary
According to Toyo Keizai Online, the crackdown on digital asset treasury (DAT) companies acquiring crypto-assets such as Bitcoin is intensifying, and Metaplanet's new inclusion in TOPIX was passed over. The episode highlights a rift between the Japan Exchange Group (JPX) and the crypto-asset industry over index inclusion. The article reports that JPX Research Institute has excluded companies with crypto-asset ratios above 50% from index inclusion.

The article characterizes the friction as a divergence between strong retail and corporate demand for crypto exposure via listed stocks and the regulatory barriers imposed by index calculators. Those barriers block inflows of passive capital, including from large institutional investors such as pension funds. The article notes that buying demand from investors seeking crypto gains through stock accounts has surged.

The analysis identifies a potential trigger in the lifting of the ban on domestic spot crypto ETFs, which would allow Bitcoin ETFs to be traded directly in securities accounts. Under this scenario, the flow of funds that had been buying corporate stocks as a substitute would change substantially. The article expects legal amendments and tax revisions to shift speculative buying from operating companies toward regulated financial products.

The article's forecast is that the practice of inflating corporate value through crypto purchases will become untenable, and that markets will scrutinize business substance and compliance with institutional standards. It expects treasury companies lacking operating businesses to be weeded out, with capital reallocated toward companies with real earnings and growth investment. The analysis also flags constraints, including regulatory approval lags, tax-system disparities on miscellaneous income, and the risk that innovation capital flows overseas.

The article's outlook for the next one to three years is that custodial infrastructure providers, such as trust banks, could gain as proxy holding premiums fade. Note that the source is a structural analysis generated by AI and is not investment advice.
