Bitcoin Regulation: Two Steps Forward, One Step Back

A Tale of Two Regulatory Climates: Progress, Pushback, and What It Means for Bitcoin

The past week delivered a striking contrast in how major economies are choosing to integrate — or resist — Bitcoin into their established financial frameworks. In the United States, a landmark regulatory approval signals a maturing relationship between crypto infrastructure and federal oversight. Meanwhile, in Japan, the country's leading stock exchange is erecting new barriers for companies whose balance sheets are anchored in Bitcoin. Together, these developments paint a nuanced picture of a global financial system still wrestling with how to categorize, accommodate, and ultimately govern the world's leading digital asset.

This is not simply a story about regulatory bureaucracy. It is a story about whether Bitcoin-native businesses will be treated as legitimate participants in mainstream capital markets — or as outliers to be managed and contained.

The Facts

On the US front, the Office of the Comptroller of the Currency (OCC) has granted Coinbase, America's largest cryptocurrency exchange, a national trust bank charter — albeit with conditions attached ^[1]. The approval is significant because it allows Coinbase to operate under a unified federal regulatory framework, eliminating the need to navigate the patchwork of state-by-state licensing requirements that has long complicated expansion for crypto firms. Importantly, Coinbase will not be permitted to engage in traditional deposit-taking or lending activities. As CEO Brian Armstrong clarified: "We're not becoming a bank, but a trust company" — the goal being to bring existing crypto infrastructure under consistent federal supervision ^[1].

The OCC decision arrives at a politically charged moment in Washington. The so-called Clarity Act, which would establish a comprehensive federal framework for digital assets, is reportedly inching toward a legislative breakthrough, with multiple stakeholders signaling cautious optimism ^[1]. However, one sticking point continues to slow progress: whether stablecoin issuers should be permitted to pass yield on to users. This single unresolved question has dragged out negotiations for months, and its resolution could determine the pace at which the Clarity Act advances through Congress ^[1].

Across the Pacific, the picture is notably more complicated for Bitcoin treasury companies. Japan Exchange Group (JPX), the operator of the Tokyo Stock Exchange, has proposed suspending the inclusion of companies whose primary assets consist of crypto holdings from its major stock indices ^[2]. The stated rationale is that such companies introduce excessive volatility into index composition, given that their valuations are almost entirely tethered to cryptocurrency prices. The proposal is currently in a public consultation phase, with implementation planned for autumn 2026 if finalized ^[2].

The company most directly affected is Metaplanet, Japan's largest publicly listed Bitcoin treasury company, which this week became the third-largest corporate Bitcoin holder globally following the purchase of an additional 5,075 BTC ^[2]. Many market participants had anticipated that Metaplanet would be included in the TOPIX — Japan's broadest and most institutionally significant equity index — during its planned expansion in October 2026. That prospect now appears to be off the table, at least temporarily ^[2]. This follows a broader trend: index provider MSCI previously considered excluding Bitcoin treasury companies from its own indices, before ultimately deciding in January 2026 to allow those with more than 50% crypto on their balance sheets to remain — for now ^[2].

Analysis & Context

The Coinbase OCC charter and the JPX index exclusion proposal may appear unrelated on the surface, but they reflect the same underlying tension: Bitcoin is large enough and institutionally embedded enough that regulators can no longer ignore it, yet uncomfortable enough that traditional financial gatekeepers are still searching for ways to limit its influence on legacy systems. What we are witnessing is not a binary acceptance or rejection of Bitcoin — it is a selective, conditional integration, shaped by institutional self-interest as much as by genuine risk assessment.

For Coinbase, the trust charter is a meaningful milestone. Historically, crypto companies operating at scale have faced the uncomfortable choice of either working within a fragmented, expensive state-licensing regime or accepting regulatory ambiguity. A federal charter solves neither problem entirely, but it represents a significant reduction in compliance friction and a powerful signal to institutional partners who require regulatory clarity before committing capital. This mirrors patterns seen in the early integration of fintech firms into traditional banking oversight — initially met with skepticism, eventually normalized. The Clarity Act, if passed, would accelerate this normalization considerably, particularly for companies building on Bitcoin and other digital assets.

The Japanese situation is more nuanced and arguably more consequential for Bitcoin's medium-term institutional adoption narrative. Index inclusion matters enormously because of the mechanics of passive investing: when a stock enters a major index like the TOPIX, billions of dollars in index-tracking capital flows into it automatically. Blocking Bitcoin treasury companies from this mechanism is not just an administrative decision — it is a structural limitation on the capital formation capacity of companies like Metaplanet. This is not an existential threat, since Metaplanet primarily finances its Bitcoin acquisitions through equity issuance rather than passive index inflows ^[2]. But it represents a significant constraint on the "flywheel" model that made Strategy's approach so powerful in Western markets. It is worth noting that Strategy itself faced similar headwinds — the MSCI debate dragged on for months before a partial reprieve — suggesting that lobbying and public engagement during consultation periods can produce real results. Metaplanet's management would be well-advised to make its case aggressively during JPX's open consultation window.

Key Takeaways

• The OCC's conditional trust charter for Coinbase marks a genuine step forward for Bitcoin infrastructure in the US, reducing compliance complexity and signaling growing federal acceptance of crypto-native financial firms.
• The Clarity Act remains the most important near-term legislative development for Bitcoin businesses in the US — the resolution of the stablecoin yield debate will determine whether it advances quickly or stalls again.
• JPX's proposed index exclusion for Bitcoin treasury companies is a serious headwind for Metaplanet's institutional growth strategy, though it does not threaten the company's core operations or its ability to accumulate Bitcoin.
• The pattern is consistent across MSCI and JPX: traditional index providers are uncomfortable with Bitcoin-heavy balance sheets, but public consultation phases have proven to be genuine opportunities for industry pushback — as the MSCI outcome demonstrated.
• Investors watching Bitcoin's macro adoption story should track both the Clarity Act's progress and the JPX consultation outcome this autumn as two of the most consequential near-term regulatory data points for the asset class.
