Four Reasons Institutional Investors Are Moving On-Chain — A Structural Shift in the BlackRock Era

① Tokenization of Existing Assets (RWA)

The RWA market reached approximately $20–26 billion (excluding stablecoins) in early 2026, posting roughly 300% year-over-year growth. The largest category is tokenized U.S. Treasuries, which expanded over 600% in 18 months to approximately $7.5 billion. BlackRock's BUIDL alone holds about $2.5 billion in AUM as of May 2026, commanding roughly 40% of the tokenized Treasury market. The yield source is identical to traditional financial instruments, but on-chain benefits—24/7 settlement, instant collateralization, and composability across protocols—attract institutions. The model is essentially "leveraging crypto infrastructure without taking crypto risk."

② Yield Generation on Crypto Holdings

The decision to hold crypto is already made on diversification and asymmetric-return grounds; staking is a secondary motivation to avoid leaving holdings idle. On March 12, 2026, BlackRock launched ETHB (iShares Staked Ethereum Trust) on Nasdaq as its first staking-enabled crypto ETF, attracting $254 million in its first week. The SEC clarified in 2025 that liquid staking does not constitute securities transactions, and the IRS permitted ETPs to stake. Solana staking ETFs, launched in November 2025, accumulated $1 billion AUM within their first month.

③ Crypto-Specific Products

Funding-rate arbitrage (e.g., Ethena USDe), basis trades, and restaking rewards represent structural alpha sources with no traditional-finance equivalent. Crypto market inefficiency itself is the alpha source, and specialist hedge funds are the primary users. An AIMA/PwC survey found 55% of hedge funds invested in crypto with average allocation of approximately 7% of assets, representing about $982 billion in surveyed AUM.

④ Portfolio-Level Sharpe Improvement

This is the foundational motivation underlying ①–③. Even if the standalone Sharpe ratio is inferior, low correlation and asymmetric upside improve the portfolio's overall Sharpe ratio. The Coinbase/EY 2025 survey found 86% of institutional investors hold or plan crypto exposure, with average allocations rising from 5% to 9% of AUM and projected to reach 18% within three years. Nomura's April 2026 survey similarly found ~80% of institutions plan 2–5% AUM allocation within three years.

[Business Development Insights]

1. RWA is the primary battleground for "crypto utility without crypto risk": Credit risk remains identical to traditional financial instruments while on-chain benefits accrue—the most accessible entry point for conservative institutions. For Japanese financial institutions considering on-chain participation, prioritizing RWA (especially tokenized Treasuries and money market funds) before staking or DeFi yield minimizes risk-taking while enabling infrastructure familiarity.
2. "Standard staking integration" becomes the decisive factor in the next ETF war: ETHB's success has triggered a flood of staking ETF applications for Solana, Cardano, and other PoS chains. Spot-only ETFs are structurally disadvantaged, making product design capabilities for embedding yield mechanisms (custodian selection, reward distribution, tax handling) the key competitive edge.
3. "Motivation-based segmentation" becomes essential in product design: The four motivations entail different client profiles, risk appetites, and regulatory requirements. Specialized services—RWA-focused (TradFi-adjacent), staking-focused (long-term holders), delta-neutral focused (hedge funds), and allocation-advisory focused (pensions/endowments)—will dominate. Generalist services treating all institutions uniformly will struggle to differentiate.
