SBI and Rakuten Securities Launch Crypto Investment Trusts in Japan

SBI Securities has roughly 50 million accounts across its banking and securities divisions [1]. Rakuten Securities serves millions more through the same Rakuten ecosystem where Japanese consumers shop, travel, and bank. On May 17, 2026, both firms confirmed they are building crypto investment trusts in-house [2]. Not buying a stake in a crypto exchange. Not partnering with a startup. Building the product themselves, inside their own regulated infrastructure, for their existing client base.

Thesis

This essay argues one thing: the trust structure is the story, not the crypto. SBI and Rakuten are not making a bet on Bitcoin prices. They are solving the two problems that kept institutional money out of crypto for a decade, custody risk and regulatory ambiguity, by wrapping digital assets inside a product format that Japan's financial establishment already understands. That design decision is replicable across every major financial market in Asia. The firms that recognize this early will define the next wave of digital asset distribution.

What Actually Happened

On May 17, 2026, Nikkei Asia reported that SBI Securities and Rakuten Securities are developing crypto investment trusts to offer retail and institutional clients Bitcoin and Ethereum exposure through their existing brokerage accounts [3]. No new wallet. No separate exchange account. No custody headache for the end investor.

This is not a pilot. SBI and Rakuten are building these products within their own groups [4]. That means internal compliance sign-off, internal legal review, and internal capital commitment. Those are not the decisions you make for a checkbox product.

Nomura is also preparing crypto investment trusts, according to reporting from crypto.news dated May 17, 2026 [5]. Nomura is Japan's largest investment bank. When Nomura, SBI, and Rakuten are all moving toward the same product structure at the same time, you are not watching experimentation. You are watching an industry coordinate.

The regulatory backdrop matters here. Japan's Financial Services Agency is moving toward allowing funds to hold Bitcoin and Ether directly, with a target date around 2028 [5]. The trust products launching now are the bridge to that regime. They let firms build distribution, client familiarity, and operational infrastructure before the final regulatory gate opens. By the time direct fund holdings are permitted, these firms will have two years of product history and client data behind them.

SBI's broader tokenization ambitions add context. In February 2026, SBI Holdings and Startale announced a Layer 1 blockchain called Strium, designed to support spot and derivatives trading of tokenized equities and asset-backed instruments on a 24/7 basis [6]. In March 2026, SBI invested $50 million in Startale as part of a $63 million Series A [7]. SBI is not dabbling in digital assets. It is building infrastructure at every layer of the stack, from blockchain rails to retail distribution products.

Why the Trust Structure Is the Story

An investment trust, in plain terms, pools assets under a licensed manager. Investors hold units. The manager holds the underlying asset. That separation does a lot of work.

First, it eliminates direct custody risk for the investor. When you buy Bitcoin on an exchange, you are exposed to that exchange's counterparty risk. Mt. Gox is the oldest lesson. FTX is the most recent one. A trust shifts custody to a regulated, audited entity operating under a legal framework with defined obligations. That is a different product for a different buyer.

Second, it eliminates regulatory ambiguity for the distributor. A brokerage selling crypto directly faces questions about whether it is operating as a crypto exchange, whether its staff need different licenses, and whether its compliance framework covers the activity. A brokerage selling units in a licensed investment trust faces none of those questions. The trust is the regulated wrapper. The brokerage is just distributing a fund, which it already knows how to do.

Third, and this is the part that gets underweighted in most coverage, the trust structure is a business model. Management fees accrue on assets under management. The more clients allocate, the more fee revenue the firm earns. That creates a financial incentive to deepen crypto infrastructure investment, not just offer the product as a loss-leader. Incumbents who build this infrastructure will not walk away from it. The fee economics lock them in.

Compare this to what KDDI did three days before this announcement. KDDI paid $65 million for a 14.9% stake in Coincheck Group [8]. That was a telecom operator buying access to crypto infrastructure through an equity stake in an exchange. It is a smart move. But it is a passive position. KDDI gets exposure to Coincheck's growth. It does not get a product it can sell to its 30 million subscribers tomorrow.

SBI and Rakuten are doing something structurally different. They are building the distribution layer on top of the infrastructure. KDDI bought a seat at the table. SBI and Rakuten are building the pipe that moves product to millions of existing clients at scale. Both moves matter. Together they describe a single pattern: Japan's established financial and corporate institutions are integrating crypto into their core business, not treating it as a side experiment.

The Regulatory Moat Japan Just Built

Japan's Financial Services Agency has been one of the more methodical crypto regulators globally. It licensed exchanges early. It imposed strict custody requirements after the Coincheck hack of 2018. It has moved slowly but in one direction: toward a framework that allows regulated institutions to participate in digital asset markets without abandoning their existing compliance obligations.

The trust product structure fits that philosophy exactly. It does not ask Japan's financial establishment to become crypto-native. It asks them to apply existing fund management rules to a new asset class. That is a much easier ask, and the FSA has signaled it agrees by allowing this product category to move forward.

The 2028 target for allowing funds to hold Bitcoin and Ether directly is the next milestone [5]. If trust product demand accelerates faster than the FSA anticipated, that timeline could move. Regulators respond to market reality. If SBI and Rakuten report strong AUM growth in their trust products through 2026 and 2027, the case for accelerating the 2028 deadline becomes harder to ignore.

For the rest of Asia, Japan's FSA has done something valuable. It has demonstrated that a conservative, well-respected financial regulator can approve crypto trust products without the sky falling. Singapore's MAS and Hong Kong's SFC both watch FSA decisions closely. The compliance template Japan just validated is replicable. The legal structures, the custody requirements, the reporting obligations, none of these are Japan-specific inventions. They are standard fund management frameworks applied to a new asset class.

The Bear Case and Why It Underestimates the Structural Shift

Skeptics will argue that investment trusts are a watered-down crypto product. Investors do not hold the underlying asset. They cannot move coins to a private wallet. They cannot use their Bitcoin as collateral in DeFi protocols. The trust structure, in this reading, is crypto with the interesting parts removed, a product designed to satisfy compliance teams rather than actual crypto users. Skeptics will also note that Japan's retail investor base is famously conservative. High savings rates and low risk appetite may mean these products attract curiosity but not meaningful AUM.

The rebuttal is in the data SBI already has. SBI's banking and securities divisions had roughly 50 million accounts as of March 2024 [1]. Even a 1% allocation rate from that base, at modest position sizes, produces AUM that justifies the infrastructure investment. The product is not designed for crypto-native users. It is designed for the investor who wants exposure without operational complexity. That is a much larger market than the crypto-native one, and it is the market that moves institutional AUM at scale.

Who Should Care and What They Should Do

If you are a family office allocator in Asia: The compliance template Japan just validated is replicable. Singapore and Hong Kong are the obvious next markets. The question is not whether similar structures will appear there. The question is whether you wait for your local regulator to approve them or position early through existing Japan-domiciled vehicles. Family offices with existing Japanese brokerage relationships can access these products as soon as they launch. That is a near-term allocation decision, not a 2028 planning exercise.

If you build fintech infrastructure, specifically custody, reporting, or fund administration: SBI and Rakuten built their trust products in-house [4]. That was possible because they have large internal technology teams and existing fund infrastructure. The next wave of issuers, regional banks, smaller brokerages, asset managers in Southeast Asia, will not have that capability. They will buy it. The custody stack, the NAV calculation engine, the investor reporting layer, these are contract opportunities. The firms that build Japan-compliant crypto trust infrastructure in 2026 will have a reference client and a working product when the Singapore and Hong Kong versions of this conversation happen in 2027.

If you manage a traditional brokerage or fund platform outside Japan: Your clients are going to ask why you do not offer this. That question is coming from retail clients who read about SBI and Rakuten, and it is coming from institutional clients who are watching Japan's financial establishment validate the product category. The answer you give in the next 12 months will define your positioning. "We are evaluating" is a fine answer for six months. After that, it starts to sound like "we missed it."

What to Watch Next

Watch for a Tier 1 Asian custodian to announce a dedicated crypto trust custody agreement. The names to watch are MUFG, DBS, and Japan's major trust banks. SBI and Rakuten built in-house, but a custody announcement from a major trust bank would signal that the infrastructure layer is scaling beyond the two firms that moved first. That is the confirmation that this is a market, not two firms experimenting.

Watch the FSA's 2028 timeline for direct fund holdings. The current target allows funds to hold Bitcoin and Ether directly by 2028 [5]. Any FSA consultation paper, public comment period, or informal guidance suggesting that timeline is under review is the signal that market demand is running ahead of the regulatory schedule. If SBI and Rakuten report strong early AUM figures, watch for the FSA to open a review process before the end of 2026.

Watch Nomura's launch date relative to SBI and Rakuten. Nomura is preparing its own crypto investment trust product [5]. If Nomura launches within 60 days of SBI and Rakuten, the competitive pressure is real and other regional players will be forced to respond faster than they planned. If Nomura takes six months, it suggests the product is harder to build than the first movers made it look, which is useful information for anyone pricing infrastructure contracts in this space.

Japan just handed the rest of Asia a working blueprint. The trust structure solves the custody problem. The FSA's approval solves the regulatory ambiguity problem. The fee model solves the incumbent incentive problem. Three problems solved in one product design. The question is not whether this spreads. The question is which market moves first to copy it, and whether the firms building the infrastructure underneath it are ready when it does.
