SBI and Rakuten build crypto trusts as Japan finalizes retail rules. The shift could unlock institutional-style exposure for ordinary Japanese investors, changing the market structure.
Japan is moving to make cryptocurrency investing accessible to ordinary retail investors through a structure that bypasses the complexity of direct exchange trading. Several of the country's largest brokerage firms, including SBI Securities and Rakuten Securities, are building in-house crypto investment trusts and exchange-traded products. Other major financial companies are holding back until the government finalizes the new regulatory framework.
The shift matters because it replaces the current retail entry point – direct purchase on crypto exchanges – with a trust-based wrapper that integrates into existing brokerage accounts. For most Japanese investors, buying Bitcoin or Ethereum through a securities account is simpler than opening a separate exchange wallet, dealing with private keys, or navigating tax reporting on each trade.
A trust structure also changes the custody and settlement mechanics. Instead of holding the underlying asset directly, investors own shares in a vehicle that holds the crypto. That shifts the counterparty risk from the individual to the trust operator, which must meet Japan's custody standards. The tax treatment may also differ: capital gains on trust shares could fall under securities tax rules rather than the more complex crypto tax regime.
SBI Securities is the most advanced. The firm already operates a crypto exchange through its SBI VC Trade subsidiary and has the balance sheet to seed a trust product. Rakuten Securities is developing its own vehicle, leveraging the group's existing crypto exchange, Rakuten Wallet. Both are betting that retail demand will follow the path of least resistance – a brokerage login rather than a separate exchange account.
The move mirrors what has happened in other markets where exchange-traded products for crypto first gained traction. In the United States, the approval of spot Bitcoin ETFs shifted billions in retail and institutional flows from direct holdings to fund structures. Japan's version could have a similar effect, though the scale will depend on the final rules.
The government has not published a firm deadline for the new regulations. The delay is creating a two-tier market: early movers like SBI and Rakuten are building products under existing frameworks, while competitors wait for clarity on capital requirements, disclosure rules, and investor protection standards.
The key decision point for traders is whether to position for the regulatory tailwind now or wait for the actual product launches. If the trusts launch with favorable tax treatment and low expense ratios, they could pull liquidity away from direct exchange trading. That would compress spreads on retail-focused exchanges and push volume into the trust structure.
For now, the most concrete signal will come from the Financial Services Agency (FSA). Any published draft of the new rules will trigger a wave of filings from brokerages that are currently sitting on the sidelines. Until then, the build-out by SBI and Rakuten is the only live data point.
Japan has historically been a significant source of retail crypto volume, particularly during the 2017-2018 cycle. A regulated trust channel could bring back a portion of that capital that moved to offshore exchanges or stayed on the sidelines due to tax complexity. The impact on Bitcoin and Ethereum will depend on the size of the initial trust offerings and whether the products allow for in-kind creation and redemption.
Investors should watch for the FSA's regulatory publication and the first prospectus filings from SBI and Rakuten. Those documents will reveal the fee structure, custody arrangements, and whether the trusts will trade on the Tokyo Stock Exchange or an alternative venue. That is the next concrete catalyst for this story.
